,twenty-seven years ago the ,british ,association met in ,bradford1 not at that time raised to the dignity of a city4 ,the meeting was very successful1 and was attended by about two thousand persons--a forecast1 let us hope1 of what we may expect at the present assembly4 ,a distinguished chemist1 ,prof4 ,a4 ,w4 ,williamson1 presided4 ,on this occasion the association has elected for the presidential chair one whose attention has been given to the study of an important department of biological science4 ,his claim to occupy1 however unworthily1 the distinguished position in which he has been placed1 rests1 doubtless1 on the fact that1 in the midst of the engrossing duties devolving on a teacher in a great university and school of medicine1 he has endeavored to contribute to the sum of knowledge of the science which he professes4 ,it is a matter of satisfaction to feel that the success of a meeting of this kind does not rest upon the shoulders of the occupant of the presidential chair1 but is due to the eminence and active coperation of the men of science who either preside over or engage in the work of the nine or ten sections into which the association is divided1 and to the energy and ability for organization displayed by the local secretaries and committees4 ,the programme prepared by the general and local officers of the association shows that no efforts have been spared to provide an ample bill of fare1 both in its scientific and social aspects4 ,members and associates will1 ,i feel sure1 take away from the ,bradford meeting as pleasant memories as did our colleagues of the corresponding ,association ,franaise1 when1 in friendly collaboration at ,dover last year1 they testified to the common citizenship of the ,universal ,republic of ,science4 ,as befits a leading center of industry in the great county of ,york1 the applications of science to the industrial arts and to agriculture will form subjects of discussion in the papers to be read at the meeting4 ,since the association was at ,dover a year ago1 two of its former presidents have joined the majority4 ,the ,duke of ,argyll presided at the meeting in ,glasgow so far back as #ahee4 ,throughout his long and energetic life1 he proved himself to be an eloquent and earnest speaker1 one who gave to the consideration of public affairs a mind of singular independence1 and a thinker and writer in a wide range of human knowledge4 ,sir ,j4 ,wm4 ,dawson was president at the meeting in ,birmingham in #ahhf4 ,born in ,nova ,scotia in #ahbj1 he devoted himself to the study of the ,geology of ,canada1 and became the leading authority on the subject4 ,he took also an active and influential part in promoting the spread of scientific education in the ,dominion1 and for a number of years he was ,principal and ,vice-,chancellor of the ,mc,gill ,university1 ,montreal4 ,,scientific ,,method4 ,edward ,gibbon has told us that diligence and accuracy are the only merits which an historical writer can ascribe to himself4 ,without doubt they are fundamental qualities necessary for historical research1 but in order to bear fruit they require to be exercised by one whose mental qualities are such as to enable him to analyze the data brought together by his diligence1 to discriminate between the false and the true1 to possess an insight into the complex motives that determine human action1 to be able to recognize those facts and incidents which had exercised either a primary or only a secondary influence on the affairs of nations1 or on the thoughts and doings of the person whose character he is depicting4 ,in scientific research1 also1 diligence and accuracy are fundamental qualities4 ,by their application new facts are discovered and tabulated1 their order of succession is ascertained and a wider and more intimate knowledge of the processes of nature is acquired4 ,but to decide on their true significance a well-balanced mind and the exercise of prolonged thought and reflection are needed4 ,william ,harvey1 the father of exact research in physiology1 in his memorable work1 #8,de ,motu ,cordis et ,sanguinis1' published more than two centuries ago1 tells us of the great and daily diligence which he exercised in the course of his investigations1 and the numerous observations and experiments which he collated4 ,at the same time he refers repeatedly to his cogitations and reflections on the meaning of what he had observed1 without which the complicated movements of the heart could not have been analyzed1 their significance determined and the circulation of the blood in a continuous stream definitely established4 ,early in the present century1 ,carl ,ernst von ,baer1 the father of embryological research1 showed the importance which he attached to the combination of observation with meditation by placing side by side on the title page of his famous treatise #8,ueber ,entwickelungsgeschichte der ,thiere' 7#ahbh7 the words ,beobachtung und ,reflexion4 ,though ,i have drawn from biological science my illustrations of the need of this combination1 it must not be inferred that it applies exclusively to one branch of scientific inquiry2 the conjunction influences and determines progress in all the sciences1 and when associated with a sufficient touch of imagination1 when the power of seeing is conjoined with the faculty of foreseeing1 of projecting the mind into the future1 we may expect something more than the discovery of isolated facts2 their cordination and the enunciation of new principles and laws will necessarily follow4 ,scientific method consists1 therefore1 in close observation1 frequently repeated so as to eliminate the possibility of erroneous seeing2 in experiments checked and controlled in every direction in which fallacies might arise2 in continuous reflection on the appearances and phenomena observed1 and in logically reasoning out their meaning and the conclusions to be drawn from them4 ,were the method followed out in its integrity by all who are engaged in scientific investigations1 the time and labor expended in correcting errors committed by ourselves or by other observers and experimentalists would be saved1 and the volumes devoted annually to scientific literature would be materially diminished in size4 ,were it applied1 as far as the conditions of life admit1 to the conduct and management of human affairs1 we should not require to be told1 when critical periods in our welfare as a nation arise1 that we shall muddle through somehow4 ,recent experience has taught us that wise discretion and careful provision are as necessary in the direction of public affairs as in the pursuit of science1 and in both instances1 when properly exercised1 they enable us to reach with comparative certainty the goal which we strive to attain4 ,,improvements ,,in ,,means ,,of ,,observation4 ,while certain principles of research are common to all the sciences1 each great division requires for its investigation specialized arrangements to insure its progress4 ,nothing contributes so much to the advancement of knowledge as improvements in the means of observation1 either by the discovery of new adjuncts to research1 or by a fresh adaptation of old methods4 ,in the industrial arts1 the introduction of a new kind of raw material1 the recognition that a mixture or blending is often more serviceable than when the substances employed are uncombined1 the discovery of new processes of treating the articles used in manufactures1 the invention of improved machinery1 all lead to the expansion of trade to the occupation of the people1 and to the development of great industrial centers4 ,in science1 also1 the invention and employment of new and more precise instruments and appliances enable us to appreciate more clearly the signification of facts and phenomena which were previously obscure1 and to penetrate more deeply into the mysteries of nature4 ,they mark fresh departures in the history of science1 and provide a firm base of support from which a continuous advance may be made and fresh conceptions of nature can be evolved4 ,it is not my intention1 even had ,i possessed the requisite knowledge1 to undertake so arduous a task as to review the progress which has recently been made in the great body of sciences which lie within the domain of the ,british ,association4 ,as my occupation in life has required me to give attention to the science which deals with the structure and organization of the bodies of man and animals--a science which either includes within its scope or has intimate and widespread relations to comparative anatomy1 embryology1 morphology1 zology1 physiology and anthropology--,i shall limit myself to the attempt to bring before you some of the more important observations and conclusions which have a bearing on the present position of the subject4 ,as this is the closing year of the century it will not1 ,i think1 be out of place to refer to the changes which a hundred years have brought about in our fundamental conceptions of the structure of animals4 ,in science1 as in business1 it is well from time to time to take stock of what we have been doing1 so that we may realize where we stand and ascertain the balance to our credit in the scientific ledger4 ,so far back as the time of the ancient ,greeks it was known that the human body and those of the more highly organized animals were not homogeneous1 but were built up of parts1 the partes dissimilares 7 ta anomoia mer7 of ,aristotle1 which differed from each other in form1 color1 texture1 consistency and properties4 ,these parts were familiarly known as the bones1 muscles1 sinews1 blood-vessels1 glands1 brain1 nerves and so on4 ,as the centuries rolled on1 and as observers and observations multiplied1 a more and more precise knowledge of these parts throughout the animal kingdom was obtained1 and various attempts were made to classify animals in accordance with their forms and structure4 ,during the concluding years of the last century and the earlier part of the present1 the ,hunters1 ,william and ,john1 in our country1 the ,meckels in ,germany1 ,cuvier and ,st4 ,hilaire in ,france1 gave an enormous impetus to anatomical studies1 and contributed largely to our knowledge of the construction of the bodies of animals4 ,but whilst by these and other observers the most salient and1 if ,i may use the expression1 the grosser characters of animal organization had been recognized1 little was known of the more intimate structure or texture of the parts4 ,so far as could be determined by the unassisted vision1 and so much as could be recognized by the use of a simple lens1 had indeed been ascertained1 and it was known that muscles1 nerves and tendons were composed of threads or fibers1 and the blood and lymph-vessels were tubes1 that the parts which we call fasci and aponeuroses were thin membranes and so on4 ,early in the present century1 ,xavier ,bichat1 one of the most brilliant men of science during the ,napoleonic era in ,france1 published his #8,anatomie ,gnrale1' in which he formulated important general principles4 ,every animal is an assemblage of different organs1 each of which discharges a function1 and acting together1 each in its own way1 assists in the preservation of the whole4 ,the organs are1 as it were1 special machines situated in the general building which constitutes the factory or body of the individual4 ,but1 further1 each organ or special machine is itself formed of tissues which possess different properties4 ,some1 as the blood-vessels1 nerves1 fibrous tissues1 etc41 are generally distributed throughout the animal body1 whilst others1 as bones1 muscles1 and cartilage1 etc41 are found only in certain definite localities4 ,while ,bichat had acquired a definite philosophical conception of the general principles of construction and of the distribution of the tissues1 neither he nor his pupil ,bclard was in a position to determine the essential nature of the structural elements4 ,the means and appliances at their disposal and at that of other observers in their generation were not sufficiently potent to complete the analysis4 ,attempts were made in the third decennium of this century to improve the methods of examining minute objects by the manufacture of compound lenses1 and1 by doing away with chromatic and spherical aberration1 to obtain1 in addition to magnification of the object1 a relatively large flat field of vision with clearness and sharpness of definition4 ,when in ,january1 #ahcj1 ,joseph ,jackson ,lister read to the ,royal ,society his memoir 8,on ,some ,properties in ,achromatic ,object-,glasses ,applicable to the ,improvement of ,microscopes10 he announced the principles on which combinations of lenses could be arranged1 which would possess these qualities4 ,by the skill of our opticians1 microscopes have now for more than half a century been constructed which1 in the hands of competent observers1 have influenced and extended biological science with results comparable to those obtained by the astronomer through improvements in the telescope4 ,in the study of the minute structure of plants and animals1 the observer has frequently to deal with tissues and organs1 most of which possess such softness and delicacy of substance and outline that1 even when microscopes of the best construction are employed1 the determination of the intimate nature of the tissue1 and the precise relation which one element of an organ bears to the other constituent elements1 is1 in many instances1 a matter of difficulty4 ,hence additional methods have had to be devised in order to facilitate study and to give precision and accuracy to our observations4 ,it is difficult for one of the younger generation of biologists1 with all the appliances of a well-equipped laboratory at his command1 with experienced teachers to direct him in his work1 and with excellent text-books1 in which the modern methods are described1 to realize the conditions under which his predecessors worked half a century ago4 ,laboratories for minute biological research had not been constructed1 the practical teaching of histology and embryology had not been organized1 experience in methods of work had not accumulated2 each man was left to his individual efforts1 and had to puzzle his way through the complications of structure to the best of his power4 ,staining and hardening reagents were unknown4 ,the double-bladed knife invented by ,valentin1 held in the hand1 was the only improvement on the scalpel or razor for cutting thin1 more or less translucent slices suitable for microscopic examination2 mechanical section-cutters and freezing arrangements had not been devised4 ,the tools at the disposal of the microscopist were little more than knife1 forceps1 scissors1 needles2 with acetic acid1 glycerine and ,canada balsam as reagents4 ,but in the employment of the newer methods of research care has to be taken1 more especially when hardening and staining reagents are used1 to discriminate between appearances which are to be interpreted as indicating natural characters1 and those which are only artificial productions4 ,notwithstanding the difficulties attendant on the study of the more delicate tissues1 the compound achromatic microscope provided anatomists with an instrument of great penetrative power4 ,between the years #ahcj and #ahej a number of acute observers applied themselves with much energy and enthusiasm to the examination of the minute structure of the tissues and organs in plants and animals4 ,,cell ,,theory4 ,it had1 indeed1 long been recognized that the tissues of plants were to a large extent composed of minute vesicular bodies1 technically called cells 7,hooke1 ,malpighi1 ,grew74 ,in #ahca the discovery was made by the great botanist1 ,robert ,brown1 that in many families of plants a circular spot1 which he named areola or nucleus1 was present in each cell2 and in #ahch ,m4 ,j4 ,schleiden published the fact that a similar spot or nucleus was a universal elementary organ in vegetables4 ,in the tissues of animals also structures had begun to be recognized comparable with the cells and nuclei of the vegetable tissues1 and in #ahci ,theodore ,schwann announced the important generalization that there is one universal principle of development for the elementary part of organisms1 however different they may be in appearance1 and that this principle is the formation of cells4 ,the enunciation of the fundamental principle that the elementary tissues consisted of cells constituted a step in the progress of biological science which will forever stamp the century now drawing to a close with a character and renown equalling those which it has derived from the most brilliant discoveries in the physical sciences4 ,it provided biologists with the visible anatomical units through which the external forces operating on1 and the energy generated in1 living matter come into play4 ,it dispelled forever the old mystical idea of the influence exercised by vapors or spirits in living organisms4 ,it supplied the physiologist and pathologist with the specific structures through the agency of which the functions of organisms are discharged in health and disease4 ,it exerted an enormous influence on the progress of practical medicine4 ,a review of the progress of knowledge of the cell may appropriately enter into an address on this occasion4 ,,structure ,,of ,,cells4 ,a cell is a living particle1 so minute that it needs a microscope for its examination2 it grows in size1 maintains itself in a state of activity1 responds to the action of stimuli1 reproduces its kind and in the course of time it degenerates and dies4 ,let us glance at the structure of a cell to determine its constituent parts and the rle which each plays in the function to be discharged4 ,the original conception of a cell1 based upon the study of the vegetable tissues1 was a minute vesicle inclosed by a definite wall1 which exercised chemical or metabolic changes on the surrounding material and secreted into the vesicle its characteristic contents4 ,a similar conception was at first also entertained regarding the cells of animal tissues2 but as observations multiplied1 it was seen that numerous elementary particles1 which were obviously in their nature cells1 did not possess an inclosing envelope4 ,a wall ceased to have a primary value as a constituent part of a cell1 the necessary vesicular character of which therefore could no longer be entertained4 ,the other constituent parts of a cell are the cell plasm1 which forms the body of the cell1 and the nucleus embedded in its substance4 ,notwithstanding the very minute size of the nucleus1 which even in the largest cells is not more than one-five-hundredth of an inch in diameter1 and usually is considerably smaller1 its almost constant form1 its well-defined sharp outline and its power of resisting the action of strong reagents when applied to the cell1 have from the period of its discovery by ,robert ,brown caused histologists to bestow on it much attention4 ,its structure and chemical composition2 its mode of origin2 the part which it plays in the formation of new cells1 and its function in nutrition and secretion have been investigated4 ,when examined under favorable conditions in its passive or resting state1 the nucleus is seen to be bounded by a membrane which separates it from the cell plasm and gives it the characteristic sharp contour4 ,it contains an apparently structureless nuclear substance1 nucleoplasm or enchylema1 in which are embedded one or more extremely minute particles called nucleoli1 along with a network of exceedingly fine threads or fibers1 which in the active living cell play an essential part in the production of new nuclei within the cell4 ,in its chemical composition the nuclear substance consists of albuminous plastin and globulin2 and of a special material named nuclein1 rich in phosphorus and with an acid reaction4 ,the delicate network within the nucleus consists apparently of the nuclein1 a substance which stains with carmine and other dyes1 a property which enables the changes1 which take place in the network in the production of young cells1 to be more readily seen and followed out by the observer4 ,the mode of origin of the nucleus and the part which it plays in the production of new cells have been the subject of much discussion4 ,schleiden1 whose observations1 published in #ahch1 were made on the cells of plants1 believed that within the cell a nucleolus first appeared1 and that around it molecules aggregated to form the nucleus4 ,schwann again1 whose observations were mostly made on the cells of animals1 considered that an amorphous material existed in organized bodies1 which he called cytoblastema4 ,it formed the contents of cells1 or it might be situated free or external to them4 ,he figuratively compared it to a mother liquor in which crystals are formed4 ,either in the cytoblastema within the cells or in that situated external to them1 the aggregation of molecules around a nucleolus to form a nucleus might occur1 and1 when once the nucleus had been formed1 in its turn it would serve as a center of aggregation of additional molecules from which a new cell would be produced4 ,he regarded1 therefore1 the formation of nuclei and cells as possible in two ways--one within prexisting cells 7endogenous cell-formation71 the other in a free blastema lying external to cells 7free cell-formation74 ,in animals1 he says1 the endogenous method is rare1 and the customary origin is in an external blastema4 ,both ,schleiden and ,schwann considered that after the cell was formed the nucleus had no permanent influence on the life of the cell1 and usually disappeared4 ,under the teaching principally of ,henle1 the famous ,professor of ,anatomy in ,gttingen1 the conception of the free formation of nuclei and cells in a more or less fluid blastema1 by an aggregation of elementary granules and molecules1 obtained so much credence1 especially amongst those who were engaged in the study of pathological processes1 that the origin of cells within prexisting cells was to a large extent lost sight of4 ,that a parent cell was requisite for the production of new cells seemed to many investigators to be no longer needed4 ,without doubt this conception of free cell-formation contributed in no small degree to the belief1 entertained by various observers1 that the simplest plants and animals might arise1 without prexisting parents1 in organic fluids destitute of life1 by a process of spontaneous generation2 a belief which prevailed in many minds almost to the present day4 ,if1 as has been stated1 the doctrine of abiogenesis cannot be experimentally refuted1 on the other hand it has not been experimentally proved4 ,the burden of proof lies with those who hold the doctrine1 and the evidence that we possess is all the other way4 ,,multiplication ,,of ,,cells4 ,although von ,mohl1 the botanist1 seems to have been the first to recognize 7#ahce7 in plants a multiplication of cells by division1 it was not until attention was given to the study of the egg in various animals and to the changes which take place in it1 attendant on fertilization1 that in the course of time a much more correct conception of the origin of the nucleus and of the part which it plays in the formation of new cells was obtained4 ,before ,schwann had published his classical memoir in #ahci1 von ,baer and other observers had recognized within the animal ovum the germinal vesicle1 which obviously bore to the ovum the relation of a nucleus to a cell4 ,as the methods of observation improved1 it was recognized that1 within the developing egg1 two vesicles appeared where one only had previously existed1 to be followed by four vesicles1 then eight1 and so on in multiple progression until the ovum contained a multitude of vesicles1 each of which possessed a nucleus4 ,the vesicles were obviously cells which had arisen within the original germ-cell or ovum4 ,these changes were systematically described by ,martin ,barry so long ago as #ahci and #ahdj in two memoirs communicated to the ,royal ,society of ,london1 and the appearance produced1 on account of the irregularities of the surface occasioned by the production of new vesicles1 was named by him the mulberry-like structure4 ,he further pointed out that the vesicles arranged themselves as a layer within the envelope of the egg or zona pellucida1 and that the whole embryo was composed of cells filled with the foundations of other cells4 ,he recognized that the new cells were derived from the germinal vesicle or nucleus of the ovum1 the contents of which entered into the formation of the first two cells1 each of which had its nucleus1 which in its turn resolved itself into other cells1 and by a repetition of the process into a greater number4 ,the endogenous origin of new cells within a prexisting cell and the process which we now term the segmentation of the yolk were successfully demonstrated4 ,in a third memoir1 published in #ahda1 ,barry definitely stated that young cells originated through division of the nucleus of the parent cell1 instead of arising1 as a product of crystallization1 in the fluid cytoblastema of the parent cell or in a blastema situated external to the cell4 ,in a memoir published in #ahdb1 ,john ,goodsir advocated the view that the nucleus is the reproductive organ of the cell1 and that from it1 as from a germinal spot1 new cells were formed4 ,in a paper1 published three years later1 on nutritive centers1 he described cells1 the nuclei of which were the permanent source of successive broods of young cells1 which from time to time occupied the cavity of the parent cell4 ,he extended also his observations on the endogenous formation of cells to the cartilage cells in the process of inflammation and to other tissues undergoing pathological changes4 ,corroborative observations on endogenous formation were also given by his brother1 ,harry ,goodsir1 in #ahde4 ,these observations on the part which the nucleus plays by cleavage in the formation of young cells by endogenous development from a parent center--that an organic continuity existed between a mother cell and its descendants through the nucleus--constituted a great step in advance of the views entertained by ,schleiden and ,schwann1 and showed that ,barry and the ,goodsirs had a deeper insight into the nature and functions of cells than was possessed by most of their contemporaries1 and are of the highest importance when viewed in the light of recent observations4 ,in #ahda ,robert ,remak published an account of the presence of two nuclei in the blood corpuscles of the chick and the pig1 which he regarded as evidence of the production of new corpuscles by division of the nucleus within a parent cell2 but it was not until some years afterwards 7#ahej to #ahee7 that he recorded additional observations and recognized that division of the nucleus was the starting-point for the multiplication of cells in the ovum and in the tissues generally4 ,remak's view was that the process of cell division began with the cleavage of the nucleolus1 followed by that of the nucleus1 and that again by cleavage of the body of the cell and its membrane4 ,klliker had previously1 in #ahdc1 described the multiplication of nuclei in the ova of parasitic worms1 and drew the inference that in the formation of young cells within the egg the nucleus underwent cleavage1 and that each of its divisions entered into the formation of a new cell4 ,by these observations1 and by others subsequently made1 it became obvious that the multiplication of animal cells1 either by division of the nucleus within the cell1 or by the budding off of a part of the protoplasm of the cell1 was to be regarded as a widely spread and probably a universal process1 and that each new cell arose from a parent cell4 ,pathological observers were1 however1 for the most part inclined to consider free cell-formation in a blastema or exudation by an aggregation of molecules1 in accordance with the views of ,henle1 as a common phenomenon4 ,this proposition was attacked with great energy by ,virchow in a series of memoirs published in his #8,archiv1' commencing in ,vol4 #a1 #ahdg1 and finally received its death-blow in his published lectures on ,cellular ,pathology1 #aheh4 ,he maintained that in pathological structures there was no instance of cell development de novo2 where a cell existed1 there one must have been before4 ,cell-formation was a continuous development by descent1 which he formulated in the expression omnis cellula e cellul4 ,,karyokinesis4 ,while the descent of cells from prexisting cells by division of the nucleus during the development of the egg1 in the embryos of plants and animals1 and in adult vegetable and animal tissues1 both in healthy and diseased conditions1 had now become generally recognized1 the mechanism of the process by which the cleavage of the nucleus took place was for a long time unknown4 ,the discovery had to be deferred until the optician had been able to construct lenses of a higher penetrative power1 and the microscopist had learned the use of coloring agents capable of dyeing the finest elements of the tissues4 ,there was reason to believe that in some cases a direct cleavage of the nucleus1 to be followed by a corresponding division of the cell into two parts1 did occur4 ,in the period between #ahgj and #ahhj observations were made by ,schneider1 ,strasburger1 ,btschli1 ,fol1 van ,beneden and ,flemming1 which showed that the division of the nucleus and the cell was due to a series of very remarkable changes1 now known as indirect nuclear and cell division1 or karyokinesis4 ,the changes within the nucleus are of so complex a character that it is impossible to follow them in detail without the use of appropriate illustrations4 ,i shall have to content myself1 therefore1 with an elementary sketch of the process4 ,i have previously stated that the nucleus in its passive or resting stage contains a very delicate network of threads or fibers4 ,the first stage in the process of nuclear division consists in the threads arranging themselves in loops and forming a compact coil within the nucleus4 ,the coil then becomes looser1 the loops of threads shorten and thicken1 and somewhat later each looped thread splits longitudinally into two portions4 ,as the threads stain when coloring agents are applied to them1 they are called chromatin fibers1 and the loose coil is the chromosome 7,waldeyer74 ,as the process continues1 the investing membrane of the nucleus disappears1 and the loops of threads arrange themselves within the nucleus so that the closed ends of the loops are directed to a common center1 from which the loops radiate outwards and produce a starlike figure 7aster74 ,at the same time clusters of extremely delicate lines appear both in the nucleoplasm and in the body of the cell1 named the achromatic figure1 which has a spindle-like form with two opposite poles1 and stains much more feebly than the chromatic fibers4 ,the loops of the chromatic star then arrange themselves in the equatorial plane of the spindle1 and bending round turn their closed ends towards the periphery of the nucleus and the cell4 ,the next stage marks an important step in the process of division of the nucleus4 ,the two longitudinal portions1 into which each looped thread had previously split1 now separate from each other1 and whilst one part migrates to one pole of the spindle1 the other moves to the opposite pole1 and the free ends of each loop are directed toward its equator 7metakinesis74 ,by this division of the chromatin fibers1 and their separation from each other to opposite poles of the spindle1 two starlike chromatin figures are produced 7dyaster74 ,each group of fibers thickens1 shortens1 becomes surrounded by a membrane1 and forms a new or daughter nucleus 7dispirem74 ,two nuclei therefore have arisen within the cell by the division of that which had previously existed1 and the expression formulated by ,flemming--omnis nucleus e nucleo--is justified4 ,whilst this stage is in course of being completed1 the body of the cell becomes constricted in the equatorial plane of the spindle1 and1 as the constriction deepens1 it separates into two parts1 each containing a daughter nucleus1 so that two nucleated cells have arisen out of a prexisting cell4 ,a repetition of the process in each of these cells leads to the formation of other cells1 and1 although modifications in details are found in different species of plants and animals1 the multiplication of cells in the egg and in the tissues generally on similar lines is now a thoroughly established fact in biological science4 ,in the study of karyokinesis1 importance has been attached to the number of chromosomes in the nucleus of the cell4 ,flemming had seen in the ,salamander twenty-four chromosome fibers1 which seems to be a constant number in the cells of epithelium and connective tissues4 ,in other cells1 again1 especially in the ova of certain animals1 the number is smaller1 and fourteen1 twelve1 four and even two only have been described4 ,the theory formulated by ,boveri that the number of chromosomes is constant for each species1 and that in the karyokinetic figures corresponding numbers are found in homologous cells1 seems to be not improbable4 ,in the preceding description ,i have incidentally referred to the appearance in the proliferating cell of an achromatic spindle-like figure4 ,although this was recognized by ,fol in #ahgc1 it is only during the last ten or twelve years that attention has been paid to its more minute arrangements and possible signification in cell-division4 ,the pole at each end of the spindle lies in the cell plasm which surrounds the nucleus4 ,in the center of each pole is a somewhat opaque spot 7central body7 surrounded by a clear space1 which1 along with the spot1 constitutes the centrosome of the sphere of attraction4 ,from each centrosome extremely delicate lines may be seen to radiate in two directions4 ,one set extends towards the pole at the opposite end of the spindle1 and1 meeting or coming into close proximity with radiations from it1 constitutes the body of the spindle1 which1 like a perforated mantle1 forms an imperfect envelope around the nucleus during the process of division4 ,the other set of radiations is called the polar and extends in the region of the pole towards the periphery of the cell4 ,the question has been much discussed whether any constituent part of the achromatic figure1 or the entire figure1 exists in the cell as a permanent structure in its resting phase2 or if it is only present during the process of karyokinesis4 ,during the development of the egg the formation of young cells1 by division of the segmentation nucleus1 is so rapid and continuous that the achromatic figure1 with the centrosome in the pole of the spindle1 is a readily recognizable object in each cell4 ,the polar and spindle-like radiations are in evidence during karyokinesis1 and have apparently a temporary endurance and function4 ,on the other hand1 van ,beneden and ,boveri were of opinion that the central body of the centrosome did not disappear when the division of the nucleus came to an end1 but that it remained as a constituent part of a cell lying in the cell plasm1 near to the nucleus4 ,flemming has seen the central body with its sphere in leucocytes1 as well as in epithelial cells and those of other tissues4 ,subsequently ,heidenhain and other histologists have recorded similar observations4 ,it would seem1 therefore1 as if there were reason to regard the centrosome1 like the nucleus1 as a permanent constituent of a cell4 ,this view1 however1 is not universally entertained4 ,if not always capable of demonstration in the resting stage of a cell1 it is doubtless to be regarded as potentially present1 and ready to assume1 along with the radiations1 a characteristic appearance when the process of nuclear division is about to begin4 ,one can scarcely regard the presence of so remarkable an appearance as the achromatic figure without associating with it an important function in the economy of the cell4 ,as from the centrosome at the pole of the spindle both sets of radiations diverge1 it is not unlikely that it acts as a center or sphere of energy and attraction4 ,by some observers the radiations are regarded as substantive fibrillar structures1 elastic or even contractile in their properties4 ,others1 again1 look upon them as morphological expressions of chemical and dynamical energy in the protoplasm of the cell body4 ,on either theory we may assume that they indicate an influence1 emanating1 it may be1 from the centrosome and capable of being exercised both on the cell plasm and on the nucleus contained in it4 ,on the contractile theory1 the radiations which form the body of the spindle1 either by actual traction of the supposed fibrill or by their pressure on the nucleus which they surround1 might impel during karyokinesis the dividing chromosome elements toward the poles of the spindle1 to form there the daughter nuclei4 ,on the dynamical theory1 the chemical and physical energy in the centrosome might influence the cell plasm and the nucleus and attract the chromosome elements of the nucleus to the poles of the spindle4 ,the radiated appearance would therefore be consequent and attendant on the physico-chemical activity of the centrosome4 ,one or other of these theories may also be applied to the interpretation of the significance of the polar radiations4 ,,cell ,,plasm4 ,in the cells of plants1 in addition to the cell wall1 the cell body and the cell juice require to be examined4 ,the material of the cell body1 or the cell contents1 was named by von ,mohl 7#ahdf7 protoplasm1 and consisted of a colorless tenacious substance which partly lined the cell wall 7primordial utricle7 and partly traversed the interior of the cell as delicate threads inclosing spaces 7vacuoles7 in which the cell juice was contained4 ,in the protoplasm the nucleus was embedded4 ,ngeli1 about the same time1 had also recognized the difference between the protoplasm and the other contents of vegetable cells1 and had noticed its nitrogenous composition4 ,though the analogy with a closed bladder or vesicle could no longer be sustained in the animal tissues1 the name #8cell' continued to be retained for descriptive purposes1 and the body of the cell was spoken of as a more or less soft substance inclosing a nucleus 7,leydig74 ,in #ahfa ,max ,schultze adopted for the substance forming the body of the animal cell the term #8protoplasm4' ,he defined a cell to be a particle of protoplasm in the substance of which a nucleus was situated4 ,he regarded the protoplasm1 as indeed had previously been pointed out by the botanist ,unger1 as essentially the same as the contractile sarcode which constitutes the body and pseudopodia of the ,amba and other ,rhizopoda4 ,as the term #8protoplasm1' as well as that of #8bioplasm' employed by ,lionel ,beale in a somewhat similar though not precisely identical sense1 involves certain theoretical views of the origin and function of the body of the cell1 it would be better to apply to it the more purely descriptive term #8cytoplasm' or #8cell plasm4' ,schultze defined protoplasm as a homogeneous1 glassy1 tenacious material1 of a jelly-like or somewhat firmer consistency1 in which numerous minute granules were embedded4 ,he regarded it as the part of the cell especially endowed with vital energy1 whilst the exact function of the nucleus could not be defined4 ,based upon this conception of the jelly-like character of protoplasm1 the idea for a time prevailed that a structureless1 dimly granular1 jelly or slime destitute of organization1 possessed great physiological activity1 and was the medium through which the phenomena of life were displayed4 ,more accurate conceptions of the nature of the cell plasm soon began to be entertained4 ,brcke recognized that the body of the cell was not simple1 but had a complex organization4 ,hemming observed that the cell plasm contained extremely delicate threads1 which frequently formed a network1 the interspaces of which were occupied by a more homogeneous substance4 ,where the threads crossed each other1 granular particles 7milkrosomen7 were situated4 ,btschli considered that he could recognize in the cell plasm a honeycomb-like appearance1 as if it consisted of excessively minute chambers in which a homogeneous more or less fluid material was contained4 ,the polar and spindle-like radiations visible during the process of karyokinesis1 which have already been referred to1 and the presence of the centrosome1 possibly even during the resting stage of the cell1 furnished additional illustrations of differentiation within the cell plasm4 ,in many cells there appears also to be a difference in the character of the cell plasm which immediately surrounds the nucleus and that which lies at and near the periphery of the cell4 ,the peripheral part 7ektoplasma7 is more compact and gives a definite outline to the cell1 although not necessarily differentiating into a cell membrane4 ,the inner part 7endoplasma7 is softer and is distinguished by a more distinct granular appearance and by containing the products specially formed in each particular kind of cell during the nutritive process4 ,by the researches of numerous investigators on the internal organization of cells in plants and animals1 a large body of evidence has now been accumulated1 which shows that both the nucleus and the cell plasm consist of something more than a homogeneous1 more or less viscid1 slimy material4 ,recognizable objects in the form of granules1 threads1 or fibers can be distinguished in each4 ,the cell plasm and the nucleus respectively are therefore not of the same constitution throughout1 but possess polymorphic characters1 the study of which in health and the changes produced by disease will for many years to come form important matters for investigation4 7,to be concluded47 ,,the ,,bubonic ,,plague4 ,,by ,,frederick ,g4 ,,novy1 ,,sc4,d41 ,m4,d41 ,,junior ,,professor ,,of ,,hygiene ,,and ,,physiological ,,chemistry ,,in ,,the ,,university ,,of ,,michigan4 ,the province of ,yunnan in ,china adjoins ,french ,tonkin and ,british ,burmah4 ,it is of interest to the student of epidemiology because from this mountainous and difficultly accessible region there has issued but recently a disease which has been considered as practically extinct4 ,frightful as have been the ravages of the pest in the middle ages1 it is noteworthy that during the past hundred years1 with the exception of two slight outbreaks 7,noja in ,italy in #ahae1 and ,vetlianka in ,russia in #ahgh71 the disease has been unknown in ,europe4 ,during this time the pest has not been extinct1 but has existed to a greater or less extent in certain parts of ,asia and in ,africa4 ,four and possibly five of these endemic foci are known to-day4 ,the province of ,yunnan is one of these regions4 ,the mountainous district of ,gurhwal1 lying along the southern slope of the ,himalayas1 is another center where the pest has continued to prevail4 ,the recent travels of ,koch in eastern ,africa have brought to light a third region about ,lake ,victoria1 in the ,british province of ,uganda1 and the ,german ,kisiba1 where the plague has existed from time immemorial1 cut off as it were from the outer world4 ,only last year ,sakharoff called attention to a fourth focus in northeastern ,china1 and it is quite likely that a fifth focus exists in ,arabia4 ,these regions are of great importance in so far as the existence of permanent endemic foci sheds not a little light upon the development and spread of those great epidemics which1 like great tidal waves1 have in the past swept over whole countries and even continents4 ,it is not known when or from whence the pest was first introduced into ,yunnan4 ,unquestionably1 it has existed in the extreme western parts of the province for many decades4 ,eventually the disease spread throughout the province1 and frightful ravages are known to have occurred in #ahga-gc4 ,repeated visitations of this dread disease have taught the natives of ,yunnan1 as well as those of ,gurhwal and of ,uganda1 to desert their villages as soon as an unusual mortality is found to prevail among the rats4 ,in spite of the frequent recurrence of the plague1 it did not spread to neighboring provinces1 largely because of the fact that little or no communication exists between ,yunnan and the adjoining ,chinese states4 ,recently1 however1 the plague did succeed in crossing the frontier1 and1 in so doing1 it has given rise to an epidemic which1 as will be presently seen1 has already made an unenviable record and has a future that no one can foretell4 ,the way in which the disease spread from ,yunnan has been quite clearly established4 ,along the ,tonkin frontier1 throughout the provinces of ,quan-si and ,yunnan1 the ,chinese maintain a large number of military posts4 ,mule supply-trains for these posts passed from province to province over the difficult mountain paths4 ,the mule-drivers were natives of ,yunnan4 ,in #ahib the plague existed in ,yunnan1 and it was in the summer of #ahic that the disease appeared at ,long-,cheou in ,quansi among the ,yunnan mule-drivers4 ,these drivers arriving at the post of ,lieng-,cheng1 after one of their journeys from ,yunnan1 repaired to the city of ,long-,cheou1 about ten miles distant4 ,during their sojourn in this city the muleteers developed the first known cases of the plague4 ,from these men the disease spread throughout the city and to the neighboring posts and villages4 ,from ,long-,cheou the plague descended the ,canton ,river and reached ,naning-,phu4 ,from thence it followed overland to the seaport ,pakhoi1 some hundred and fifty miles distant4 ,a few months later1 in ,february1 #ahid1 it reached ,canton1 either by descending the river from ,naning-,phu or by boat from ,pakhoi4 ,that the plague at ,canton1 in #ahid1 had not lost any of its old-time destructiveness is seen in the fact that it is estimated to have caused not less than one hundred thousand deaths in ,canton in the short space of two months4 ,from ,canton the plague spread to ,hong ,kong in ,april1 #ahid4 ,it was during the existence of this epidemic that the first bacteriological studies of the disease were made and resulted in the discovery of the plague bacillus4 ,in the fall of #ahid1 the disease died out in ,hong ,kong1 but it reappeared in #ahie and #ahif4 ,considering the fact that ,hong ,kong is one of the most important maritime centers1 it is not surprising to find that in the spring of #ahif the plague was carried by shipping to the ,island of ,formosa4 ,it is quite certain that about the same time the plague was carried from ,hong ,kong to ,bombay4 ,at all events1 the existence of this disease was recognized in ,bombay in ,september1 #ahif1 by ,doctor ,viegas4 ,previous to this date1 the mortality in ,bombay was abnormally high1 undoubtedly due to the very unsanitary condition of the overcrowded city4 ,the existence of famine in ,india1 together with the filthy1 overcrowded condition of the population1 enabled the plague to gain a firm foothold in a relatively short time4 ,indeed1 there can be no doubt but that the disease was well established at the time it was first recognized4 ,it is no wonder1 then1 that in spite of the most stringent precautions1 it spread like wildfire1 so that in a short time the weekly deaths from the plague rose to nearly #b1jjj4 ,in the face of such a relentless enemy1 it is but natural that a large proportion of the population should seek safety in flight4 ,it is believed that fully #cjj1jjj people left ,bombay shortly after the plague developed4 ,there can be no doubt but that these refugees1 directly or indirectly1 carried the disease to the neighboring villages1 and thus contributed to the enormous dissemination of the pest throughout ,western ,india4 ,in the ,presidency of ,bombay there were reported1 in less than three years1 more than #bbj1jjj cases1 with more than #afd1jjj deaths4 ,when it is furthermore recognized that the natives concealed the existence of the disease as much as possible1 it will be evident that these figures reveal a partial but1 nevertheless1 a grim truth4 ,with ,bombay and the surrounding country thus seriously infected1 it became merely a question of time when the disease would be carried to other ports and countries1 by vessels and by overland routes4 ,in spite of the sanitary perfection which we may flatter ourselves on having attained in recent years1 it is nevertheless a fact that the disease is slowly but steadily and1 as it were1 stealthily invading port after port4 ,that the sanitary methods1 however1 are not at fault is seen in the fact that when an early and prompt recognition occurred1 the disease has been held in check4 ,the insidious spread of the disease is rather due to the enormous development of commerce and to the rapid means of communication with distant countries4 ,from ,bombay the plague has spread to ports on the ,persian ,gulf1 on the ,red ,sea1 and has reached ,alexandria4 ,aden1 ,djeddah1 ,port ,said1 ,cairo1 have all had outbreaks of the disease4 ,beirut and ,smyrna have each developed straggling cases4 ,isolated cases have been met with in ,london1 at ,st4 ,petersburg and in ,vienna4 ,however1 only three appreciable outbreaks have as yet occurred on ,european soil4 ,the first was that at ,oporto in ,portugal1 where one hundred and sixty cases1 with fifty-five deaths1 have developed up to the present time4 ,the second outbreak occurred at ,kolobovka1 a village near ,astrakhan4 ,of the twenty-four cases that developed there in ,july and ,august1 #ahii1 twenty-three died4 ,the last outbreak is that at ,glasgow1 where the disease made its appearance but a few weeks ago4 ,in addition to following the great international highway of ,suez1 the disease has insidiously spread to the countries of ,east ,africa4 ,mauritius and ,madagascar1 with the adjoining mainland of ,mozambique and ,lorenzo ,marquez1 have become more or less infected1 and1 if reports are to be credited1 it has also appeared in one of the ,boer towns and also on the ,ivory ,coast in ,western ,africa4 ,last fall the disease reached ,south ,america4 ,it apparently was first recognized at ,santos1 in ,brazil1 during ,october1 although early in ,september1 according to reports1 a peculiar disease1 causing swelling of the glands and death within forty-eight hours1 was reported at ,asunion1 the capital of ,paraguay4 ,at the present time ,rio ,janeiro is infected4 ,the sanitary condition of these ,south ,american cities is far from being the best1 and1 consequently1 there is but little hope that the disease will be eradicated or even held in check4 ,with ,south ,america more or less thoroughly infected1 it is evident that the ,united ,states1 as well as ,europe1 are now threatened from all sides4 ,the gravity of the situation is seen in the fact that already last ,november two cases of the plague were found in ,new ,york harbor aboard a coffee ship from ,santos4 ,several cases have also developed on ships bound from the latter city for ,mediterranean ports4 ,the ,united ,states is threatened not merely from the ,east ,atlantic and ,south ,atlantic1 but also from the ,pacific4 ,as a matter of fact1 the danger to our ,pacific ports is greater1 owing to the direct communication with the ,orient4 ,it has been already indicated that ,hong ,kong has continued to be infected ever since #ahid4 ,on several occasions it disappeared during the winter months1 only to reappear in spring4 ,with the more or less constant prevalence of the plague at this great seaport1 it necessarily will lead directly or indirectly to a dissemination of the disease along the entire ,pacific4 ,already it has prevailed at ,amoy1 and has even extended to other ,chinese ports as far as ,niu-,chwang4 ,for several years it has already persisted on the island of ,formosa4 ,japan was invaded last fall at ,kobe and at ,osaka1 and although it disappeared during the winter1 yet only a few weeks ago it has reappeared at the latter city4 ,sidney in ,australia1 and ,noumea in ,new ,caledonia1 are also infected at the present time4 ,manila1 ,honolulu and ,san ,francisco have successively become infected4 ,in all these places the disease1 with but very few exceptions1 has attacked the native or ,oriental population4 ,the extinction of the plague in the ,hawaiian ,islands since the end of ,march is a splendid demonstration of what energetic1 vigorous measures can accomplish4 ,the presence of the plague since ,march #h in ,chinatown1 in ,san ,francisco1 is readily recognized as a most serious condition1 especially after the courts have granted an injunction restraining the health officers from carrying out the necessary vigorous preventive measures4 ,a few words should be given here to the overland dissemination of the disease4 ,europe is not merely threatened by infected ships which may come from ,china1 ,india1 ,eastern ,africa or ,south ,america4 ,the overland routes from ,china and ,india are fully as grave a source of danger4 ,indeed1 as will be presently shown1 these are the routes along which the great epidemics of cholera and plague have always traveled in the past4 ,one of these great caravan routes leads from ,lahore in ,punjab through ,afghanistan into the ,russian province of ,turkestan1 where it meets the ,trans-,caspian railway4 ,this railway begins at ,samarcand in ,turkestan1 and passes through ,bokhara1 ,merv1 ,askabad and ends at ,uzun ,ada on the ,caspian ,sea opposite ,baku4 ,early in #ahii an outbreak of the plague occurred near ,samarcand1 undoubtedly brought up from ,india4 ,the precautions taken to prevent the spread were entirely successful1 and although no accounts have been officially published as to the means employed1 nevertheless it will be seen that the radical procedure employed by ,loris ,melikoff some twenty years ago was again resorted to4 ,inasmuch as the entire village was said to be afflicted it was surrounded by troops1 and no one was allowed to enter or leave4 ,the village and all that it contained was destroyed by fire4 ,with this route open continually it is evident that fresh importation must be expected sooner or later4 ,apparently a new plague focus1 independent of that in ,yunnan and ,hong ,kong1 has been recently discovered in ,manchuria4 ,the plague seems to have existed in this province for more than ten years under the name of ,tarabagan plague1 and is believed to be spread by a rodent1 the ,arctomis cobuc1 which is subject to a hemorrhagic pneumonia4 ,the presence of such an independent endemic focus in ,manchuria indicates the possibility of the spread of the disease by caravan to ,lake ,baikal1 and thence by the ,siberian railroad to ,russia4 ,indeed1 the epidemic of pneumonic type which began ,july1 #ahii1 at ,kolobovka1 in ,astrakhan1 while it may have been imported from ,persia1 might also owe its origin to the ,mongolian focus4 ,russia1 however1 is not the only country endangered by the overland transmission of the disease4 ,there are commercial highways which lead from ,northwestern ,india through ,baluchistan and ,persia to the ,caucasus1 and through ,turkey to ,constantinople4 ,grave danger threatens from this source1 and more especially from the cities along the ,persian ,gulf4 ,two important cities here are already infected1 namely1 ,bushire1 in ,persia1 and ,bassorah on the ,tigris1 in ,turkey4 ,it would appear as if ,turkey and ,persia would escape with difficulty from a visitation of this dread disease4 ,such1 then1 is the geographical distribution of the present outbreak of the plague4 ,this1 an apparently extinct disease1 has suddenly reappeared and given evidence of its power to spread death and desolation4 ,fortunately1 however1 modern sanitary precautions are quite able to restrict its progress1 provided they be applied at the proper time and place4 ,filth and overcrowding1 protracted wars and famine1 have been the powerful allies of the plague in the past4 ,through their aid this disease has made a deep impression upon the pages of history4 ,it may not be out of place1 therefore1 to turn from the present outbreak of the disease and trace its grewsome past4 ,in ancient writings references are found which would seem to indicate the existence of the plague at a very early date4 ,the ,bible contains several such references 7,deuteronomy1 ,chapter #bh1 paragraph #bg4 ,samuel ,i1 ,chapter #e1 paragraphs #f1 #i74 ,the latter especially deals with the plague which attacked the ,philistines after they took the ark4 ,the rle of rats in the dissemination of the disease is1 as some believe1 apparently referred to in the trespass offering of 8five golden emerods and five golden mice40 ,the return of the ark1 together with this trespass offering1 brought also the plague1 8because they had looked into the ark of the ,lord1 even he smote of the people fifty thousand and threescore and ten men40 ,poussin's painting of this ,philistine plague1 exhibited in the ,louvre1 shows several dead rats on the streets4 ,it is evident that the susceptibility of the rat to the plague had been noticed even at this early date4 ,the plague of boils visited upon the ,egyptians as related in ,exodus 7,chapter #i1 paragraphs #i and #aj7 has also been taken to indicate the pest of today1 but neither of these scriptural references can be said to be sufficiently definite4 ,the ,attic plague1 which ravaged the ,peloponnesus #dcj years before ,christ1 has been accurately described by an eye-witness1 the historian ,thucydides4 ,his narration may be considered the earliest exact record of an epidemic4 ,like all the great epidemics of subsequent ages1 it was ushered in by the overcrowding1 the misery and the famine consequent upon prolonged wars4 ,the combustible material was there1 and all that necessary was the spark to begin the work of death and devastation4 ,it is noteworthy that the origin of the pest was traced by ,thucydides to ,egypt or ,ethiopia1 from whence it spread gradually overland to ,asia ,minor and thence by boat to ,athens4 ,the nature of this first great historic epidemic is and will remain uncertain4 ,there are those who consider the ,attic pestilence as one of bubonic plague1 but the fact that in the very careful description of the disease no mention is made of buboes and the statement that death occurred from the seventh to the ninth day would indicate that the disease was something else4 ,buboes are characteristic1 it is true1 of the plague1 but it should be remembered that outbreaks of the pneumonic form1 with little or no glandular enlargement are not uncommon4 ,death1 however1 in the case of plague is very common on the second or third day1 and is less liable to occur in more protracted cases4 ,these facts lead to the commonly accepted belief that the ,attic pest was not the bubonic plague4 ,it may have been typhus fever1 possibly smallpox4 ,the great pestilence which devastated ,rome and its dependencies in #aff1 ,anno ,domini1 is known as the plague of ,antoninus or of ,galen4 ,this prolonged epidemic was brought to ,rome by the returning legions from ,seleucia4 ,it was not characterized by buboes1 and it is very probable that it was largely smallpox4 ,on the other hand1 the plague of ,saint ,cyprian1 which prevailed from #bea to #bff ,anno ,domini1 may have been partly bubonic in nature1 since1 it prevailed during the fall and winter months and ceased during the hot summer4 ,the disease was said to be communicated by means of clothing and by the look4 ,it spread from ,ethiopia to ,egypt and thence through the known world4 ,although the above early epidemics cannot be identified with the bubonic plague1 there is nevertheless excellent evidence of the existence of this disease in remote antiquity4 ,the first undoubted testimony on this point is that furnished by ,rufus of ,ephesus1 who lived in the first century of the ,christian era4 ,the writings of this author are no longer extant1 but they are quoted by ,oribasius1 the physician and friend of ,julian the ,apostate1 who lived in the fourth century4 ,the writings of ,oribasius were discovered in the ,vatican ,library and were published early in this century by ,cardinal ,mai4 ,in the forty-fourth 8,book of ,oribasius0 occurs the extract taken from ,rufus of ,ephesus1 from which it appears that 8the so-called pestilential buboes are all fatal and have a very acute course1 especially when observed in ,libya1 ,egypt and in ,syria4 ,dionysius mentions it4 ,dioscorides and ,posidonius have described it at length in their treatise upon the plague which prevailed during their time in ,libya40 ,the description which then follows of the buboes and of the disease is an exact counterpart of the present plague4 ,the writings of the authors quoted by ,rufus are no longer extant1 but one thing is certain1 and that is that the ,dionysius referred to lived not later than #cjj years before ,christ4 ,the other two physicians lived in ,alexandria contemporaneous with the birth of ,christ4 ,it may1 therefore1 be considered as an established fact that the plague existed in ,egypt1 ,libya and ,syria as early as #cjj years before ,christ4 ,this is of especial interest in view of the recent discovery by ,koch of an endemic plague focus in ,british ,uganda and ,german ,kisiba1 at the headwaters of the ,nile4 ,whether it ever invaded ,european territory prior to the sixth century is unknown4 ,the great plague of ,justinian which broke out in #edb1 ,anno ,domini1 appeared first in ,egypt1 and from thence it spread east and west throughout the known world and persisted for more than a half century4 ,so unknown was the plague in ,europe at that time that the physicians of ,constantinople considered it a new disease4 ,procopius1 who was an eye-witness of the plague at ,constantinople1 states that the daily mortality in that city was at times over #aj1jjj4 ,the pandemic of ,justinian resulted in the distribution of the plague for the first time throughout the length and breadth of known ,europe4 ,from that time on the early chroniclers make repeated mention of devastating plagues consequent upon the miseries of war and famine4 ,the descriptions of these pestilences are1 as a rule1 insufficient to identify them with the bubonic plague4 ,typhus1 scurvy1 smallpox and other diseases undoubtedly alternated in the work of destruction4 ,of the scores of epidemics thus recorded during the eight centuries following this first visitation few1 indeed1 can be identified to a certainty with the bubonic plague1 and yet there can be no doubt but that this disease occupied no second rank during the dreary darkness of the middle ages4 ,this era in history may be said to have been ushered in by the ,justinian plague1 and it was closed by an even more disastrous outbreak of this same disease4 ,all the ravages and slaughter consequent upon the great historic battles1 when taken together1 pale into insignificance on comparison with that dread visitation of the fourteenth century1 the #8black death'4 ,it is noteworthy that this great historic epidemic did not originate in ,egypt1 as did many of its predecessors4 ,without exception the contemporaneous writers ascribe its origin to ,cathay1 or the ,china of today4 ,this fact is of interest when it is borne in mind that at the present time we know of the existence of two endemic foci in ,china1 besides that of ,gurhwal in ,india1 of ,beni ,cheir in ,arabia and of ,uganda and ,kisiba in ,africa4 ,whatever may have been its source1 the fact is that it advanced from the ,orient along the three principal routes of travel4 ,one of these led from the ,persian ,gulf through ,bassorah and ,bagdad along the ,euphrates1 across ,arabia to ,egypt and ,northern ,africa4 ,another route passed from ,india through ,afghanistan1 and skirting the southern borders of the ,caspian and ,black ,seas1 eventually reached ,asia ,minor4 ,a third route from ,turkestan and ,china led around the northern shore of the ,caspian ,sea to ,crimea1 and thence to ,constantinople4 ,it was along these several routes that the plague advanced and spread over most of ,western ,asia and ,northern ,africa4 ,the ,european black death1 however1 can be traced with accuracy to the ,crimean peninsula4 ,gaffa1 a town in ,crimea1 now known as ,theodosia1 had been founded and fortified by the ,genoese4 ,it1 as well as other cities along the ,black ,sea1 was largely populated by ,italians4 ,one of these1 ,gabriel de ,mussis1 a lawyer in ,gaffa1 has left a faithful account of his experience and share in the introduction of the plague into ,europe4 ,in #acdf in the ,orient numberless ,tartars and ,saracens were attacked with an unknown disease and sudden death4 ,in the city of ,tanais1 through some excess1 a racial struggle ensued between the ,tartars and the ,italian merchants4 ,the latter eventually escaped and took refuge in ,gaffa1 which in time was besieged by the ,tartars4 ,during the siege1 which lasted three years1 the ,tartar hordes were attacked by the plague1 which daily carried off many thousands4 ,the besiegers1 despairing of reducing the city by direct attack1 attempted to do so in another way4 ,by means of their engines of war they projected the dead bodies into the beleaguered city1 which1 as a result1 soon became infected4 ,the ,christian defenders took to their ships1 and abandoning ,gaffa1 sailed westward1 touching at ,constantinople1 ,greece1 ,italy and ,france4 ,wherever the infected vessels touched they left the plague4 ,constantinople thus became infected early in #acdg4 ,during the summer ,greece1 ,sardinia1 ,corsica and parts of the ,italian coast developed the disease4 ,in the fall it reached ,marseilles4 ,the following year it spread inland into ,italy1 ,france1 ,spain1 and even into ,england4 ,in another year or two it spread over ,germany1 ,russia1 and crossed to the ,scandinavian peninsula4 ,within four years it had completed the circuit of ,europe1 spreading untold death and misery4 ,no greater catastrophe has been recorded in the history of the world4 ,the rapidity with which the disease spread among the fugitives from ,gaffa1 and in the cities visited by their ships1 is despairingly narrated by ,de ,mussis1 who1 returning in one of the ships to ,genoa1 says3 8,after landing we entered our homes4 ,inasmuch as a grave disease had befallen us1 and of the thousands that journeyed with us scarcely ten remained1 the relatives1 friends and neighbors hastened to greet us4 ,woe to us who brought with us the darts of death1 who scattered the deadly poison through the breath of our words40 ,according to this writer #dj1jjj died in ,genoa1 leaving scarcely a seventh of the original population4 ,venice was said to have lost #ajj1jjj1 ,naples #fj1jjj1 ,sienna #gj1jjj1 ,florence #ajj1jjj4 ,all told1 ,italy lost half of its population4 ,of the contemporaneous writers none has printed the horrors of the plague more vividly than does ,boccaccio in his introduction to the #8,decameron4' 8,what magnificent dwellings1 what notable palaces were then depopulated to the last person6 ,what families extinct6 ,what riches and vast possessions left1 and no known heir to inherit6 ,what numbers of both sexes in the prime and vigor of youth1 whom in the morning either ,galen1 ,hippocrates1 or sculapius himself but would have declared in perfect health1 after dining with their friends here have supped with their departed friends in the other world60 ,from ,marseilles the plague spread through ,provence with disastrous results4 ,in some monasteries not even a single survivor was left4 ,in one of these ,petrarch's brother buried thirty-four of his companions4 ,at ,avignon1 the seat of the ,pope1 #a1hjj deaths occurred in three days4 ,in ,paris more than fifty thousand died of the plague4 ,in ,england the black death appeared in ,august1 #acdh1 and continued till the autumn of #acdi1 when it disappeared4 ,london1 which at that time probably had a population of #de1jjj1 had a mortality of about #bj1jjj4 ,no exact statement can be made of the relative mortality in ,england1 although many undoubtedly extravagant guesses are recorded by contemporaneous writers4 ,it is estimated that the population of ,europe previous to the outbreak of the black death was about one hundred and five millions4 ,one quarter of the population1 or about twenty-five millions1 are said to have died of the plague4 ,this may be but a mere estimate1 it may be grossly inaccurate1 but it nevertheless indicates the deadly character of the pestilence4 ,according to a report made to ,pope ,clement ,,vi1 the total mortality for the known world was placed at forty-three millions4 ,one-half the population of ,italy succumbed4 ,the ,order of ,minorites in ,italy lost #cjj1jjj members4 ,the ,order of ,capuchins in ,germany lost #abf1jjj members1 while the total of deaths in ,germany was placed at #a1bjj1jjj4 ,the invasion of ,europe by the black death was sudden and rapid4 ,the seeds of the disease1 once planted on ,european soil1 persisted1 as might be expected1 for no little time4 ,although the great epidemic was said to have lasted till #acfj1 it must not be inferred that it then ceased altogether4 ,diverse localities retained the infection1 and1 as a result1 new outbreaks1 though to a less extent1 continued to outcrop during the following years4 ,from that time on every decade or two witnessed more or less pronounced outbreaks of the disease in ,france1 ,england and ,italy4 ,the chroniclers of those local outbreaks during the latter half of the fourteenth and during the entire fifteenth century did not always make it clear that the pestilence described was the real plague4 ,it was but natural to include typhus and other diseases under the dreaded term of pest4 ,nevertheless1 the frequency of these outbreaks indicates the persistence and the wide dissemination of the plague during those years4 ,during the sixteenth century the plague apparently began to show a decrease in its frequency1 although during this period1 as before1 other epidemic diseases were mistaken for it4 ,germany1 ,holland1 certain cities in ,france1 and especially in ,italy were scourged by the plague during this century4 ,the noteworthy outbreak in ,italy in #aege-gg was due to fresh importation from the ,orient4 ,the disease spread throughout ,italy1 and the devastation it caused was not inferior to that of the great plague two centuries before4 ,for example1 in #aegf in ,venice #gj1jjj died of the disease4 ,during the seventeenth century the plague asserted itself with great severity4 ,following a famine1 it prevailed in ,russia in #afja-afjc1 and some idea of its destructiveness may be gained when it is stated that in ,moscow alone #abg1jjj lives were taken4 ,during the following decade even greater epidemics prevailed in ,western ,europe4 ,france and ,england were invaded1 and in ,switzerland it even penetrated to the highest ,alps4 ,basel in #afji-afaa had #d1jjj deaths1 while ,london in #afjc yielded #cc1jjj4 ,the terrible epidemic which ravaged ,northern ,italy in #afbi-afca deserves more than a passing notice4 ,during those years more than a million died of the disease4 ,scarcely a town in ,northern ,italy escaped4 ,the city which1 perhaps1 suffered the most was ,milan1 where1 in #afcj1 the deaths from all diseases are said to have amounted to #ahf1jjj4 ,the ,milan outbreak has been graphically described by ,manzoni1 in his celebrated #8,i ,promessi ,sposi4' ,unrecognized1 the disease entered ,milan in ,october1 #afbi4 ,the mild cases which were met with during the winter months lulled the fears of the people and encouraged the mass of physicians to deny the existence of the plague4 ,but in ,april the disease began to assert itself in terrible earnest4 ,the frenzied populace1 blind to the contagiousness of the disease1 were possessed with the strange hallucination that obtained during former plague epidemics in other ,italian cities1 that the pest spread because of poison scattered about by evil-minded persons4 ,suspicious strangers were1 as a result1 stoned in the streets1 imprisoned and even put to death by legal process because of such fanatical beliefs4 ,to offset the growing pestilence1 the people demanded of the ,archbishop that a solemn religious procession be held1 and that the holy relics of ,saint ,charles be exposed4 ,at first this was refused1 but eventually it was granted4 ,the procession bearing the saintly body was solemnly held on the #aath of ,june4 ,the fanatical security which these devotions engendered was rudely shattered when1 a few days later1 the disease burst forth with renewed activity among all classes in all parts of the city4 ,nevertheless1 as ,manzoni observes1 the faith was such that none recognized that the procession itself was directly the cause of the new outburst of the disease by facilitating the spread of the contagion4 ,again the belief asserted itself that the #8untori1' or poisoners1 mixed with the crowd and with their unguents and powders had infected as many as possible4 ,from that day the fury of the contagion continued to grow to such an extent that scarcely a house remained exempt from the disease4 ,the number of patients in the pesthouse rose from #b1jjj to #ab1jjj1 and later reached #ag1jjj4 ,the daily mortality rose from #ejj to #a1bjj1 then #a1ejj1 and is even said to have reached #c1ejj4 ,milan1 before the epidemic1 was said to have had a population of from #bjj1jjj to #bej1jjj4 ,the loss by death has been variously estimated at from #adj1jjj to #ahf1jjj4 ,all these deaths were not due to the plague4 ,thus1 large numbers of children died as a result of starvation consequent upon the death of their parents from the plague4 ,the horrors attendant upon such a dreadful visitation can well be imagined4 ,scarcity of help in removing the dead and in taking care of the sick made itself felt1 to say nothing of the lack of food4 ,enormous trenches1 one after another1 were filled with the bodies of the victims1 carried thither by the hardened monatti1 the counterpart of the ,florentine becchini1 so well portrayed by ,lord ,lytton in his #8,rienzi4' ,these bearers of the sick and dead were naturally recruited from the lowest criminal classes1 and it can1 therefore1 cause but little wonder that an epidemic of the worst of crimes was associated with that of the plague4 ,in #afef ,italy was again invaded by the plague1 and on that occasion ,genoa lost #fe1jjj of its population by death4 ,about the same time terrible epidemics of the disease ravaged ,russia1 ,turkey and ,hungary4 ,london1 in #affe1 suffered dreadfully from the plague4 ,the disease appears to have been imported from ,holland1 where it was known to have existed for some time4 ,the progress of the disease in ,london has been vividly portrayed by ,defoe in the #8,journal of the ,plague ,year' and in the #8,due ,preparations for the ,plague4' ,it is supposed that the pest had been imported in bales of goods from ,smyrna into ,holland in #affc4 ,from thence it crossed over to ,london1 where the first deaths were reported about the first of ,december in #affd4 ,toward the end of that month another death occurred in the same house1 but during the following six weeks no new case developed4 ,about the middle of ,february1 however1 a person died of the plague in another house4 ,from that time only occasional cases of plague were reported1 although the weekly mortality was rapidly rising and was greatly in excess of the usual rate4 ,thus1 while the ordinary weekly mortality ranged from two hundred and forty to three hundred1 this was gradually increased1 so that in the third week in ,january it had risen to four hundred and seventy-four4 ,after a slight remission1 the mortality again rose1 so that early in ,may plague cases were reported more frequently4 ,it soon became evident that the plague1 as in ,milan in #afcj1 had slowly but surely gained a firm foothold4 ,the increased mortality was undoubtedly due to unsuspected plague cases of either the pneumonic or the septicemic type4 ,during ,may1 and especially during the hot weather in ,june1 the disease continued to spread4 ,at the same time1 the panic-stricken people began to leave the city in large numbers4 ,in ,july the condition was truly deplorable4 ,to quote ,defoe3 8,london might well be said to be all in tears2 the mourners did not go about the streets1 indeed1 for nobody put on black or made a formal dress of mourning for their nearest friends2 but the voice of mourning was truly heard in the streets4 ,the shrieks of women and children at the windows and doors of their houses1 where their dearest relations were perhaps dying1 or just dead1 were so frequent to be heard as we passed in the streets1 that it was enough to pierce the stoutest heart in the world to hear them4 ,tears and lamentations were seen almost in every house1 especially in the first part of the visitation2 for toward the latter end men's hearts were hardened1 and death was so always before their eyes1 that they did not so much concern themselves for the loss of their friends1 expecting that themselves should be summoned the next hour40 ,london at this time had a population of nearly half a million4 ,the deaths from the plague during #affe1 as reported in the bills of mortality1 are #fh1eif4 ,by far the larger number of these occurred in ,august1 ,september and ,october4 ,the weekly mortality from the disease rose from a few cases in ,may to over #g1jjj per week in ,september4 ,it may1 indeed1 be close to the truth when ,defoe states that #c1jjj were said to have been buried in one night4 ,the great plague of ,london in #affe was by no means the only visitation of that kind4 ,from the time of the black death in #acdh1 ,london had a continuous record of plague infection4 ,on an average it had an epidemic of plague every fifteen years4 ,some of these were fully as severe as that of #affe4 ,thus1 in #afjc1 with a population of #bej1jjj1 there were over #cc1jjj reported deaths from the plague4 ,in #afbe1 #da1jjj died of pest out of a population of #cbj1jjj4 ,one of the most remarkable facts in connection with the great plague is this--that it was the last in ,england4 ,the great fire of #afff is supposed to have extinguished the plague1 but this cannot be said to be true4 ,the disease continued to a slight extent in #afff and isolated cases were reported as late as #afgi1 but after that date it disappeared completely and from that time until this year ,england has been absolutely free from the plague4 ,the sudden extinction of the plague in ,england after it had become domesticated1 so to speak1 for nearly three centuries1 is indeed difficult to explain4 ,creighton sees an inhibiting influence in the growth of the practice of burial in coffins4 ,but the absence of famine1 together with the cessation of domestic wars and strife and the abeyance of want and misery1 had not a little effect4 ,as will presently be seen1 the extinction of the plague in ,england was no more remarkable than its disappearance from ,western ,europe4 ,the history of plague in the seventeenth century does not close with the ,london epidemic4 ,from #afge-afhd the disease ravaged ,northern ,africa1 ,turkey1 and from thence invaded ,austria and even reached ,southern ,germany4 ,the ,vienna outbreak of #afgi can be said to have been no less terrible than that of ,milan or of ,london4 ,the deaths from the plague in ,vienna in that year have been variously estimated at from #gj1jjj to double that number4 ,from ,vienna the plague reached ,prague1 where in #ahfa it is said to have caused no less than #hc1jjj deaths4 ,it is not to be wondered at that a nation scourged by thirty years of relentless warfare1 by religious persecution and finally tried thus severely by the plague should inscribe upon the equestrian statue of their patron saint the heart-rending appeal1 #8,lord1 grant that we do not perish4' ,the close of the seventeenth century saw the disappearance of the plague from ,western ,europe4 ,in ,eastern ,europe1 however1 the disease continued to exist even during the eighteenth century4 ,nevertheless1 a change had taken place for the better1 and as the years went on the retrogression of the plague became more and more distinct4 ,during the first two decades of the eighteenth century the plague was widely distributed in ,eastern ,europe4 ,it was present especially in ,constantinople and in the ,danubian provinces4 ,from the latter it extended to ,russia 7,ukraine71 and from thence to ,poland4 ,the disastrous invasion of ,russia by ,charles ,,xii4 of ,sweden1 ending in his defeat at ,poltawa in #agji1 led to its further dissemination to ,silesia1 ,eastern ,prussia1 the ,baltic provinces and seaports1 and even to ,scandinavia4 ,it was during this epidemic that ,dantzic1 in #agji1 lost #cc1jjj1 and ,stockholm #dj1jjj by the plague4 ,during the years #agji and #agaj the plague mortality in the ,baltic provinces exceeded #cjj1jjj4 ,three years later1 in #agac1 the plague spread up the ,danube and reached ,vienna1 ,prague and even ,bavaria4 ,during these two decades ,western ,europe was entirely free from the dread disease4 ,in #agbj the disease suddenly developed in ,marseilles and extended from thence to neighboring towns and the country districts of ,provence4 ,terrible as was this visitation it is of interest1 inasmuch as it was the last occurrence of the plague on ,french soil1 and the last in ,western ,europe until the recent outbreak in ,portugal4 ,the plague was said to have been imported into ,marseilles by a merchant vessel1 the #8,grand ,saint ,antoine'1 from ,syria4 ,on its way to ,marseilles several deaths occurred on shipboard1 but the cause was overlooked4 ,on the #beth of ,may1 #agbj1 two days after the arrival of the vessel1 another death occurred among the crew4 ,the disease was still not believed to be the plague1 and although quarantine was instituted1 new cases appeared among the crew and the dock laborers employed in unloading the vessel1 and it was not until the disease reached the city that its true nature was recognized4 ,the germs of the disease had then been scattered broadcast4 ,unsanitary a city as ,marseilles is to-day1 it must have been vastly more so in #agbj4 ,the result of the addition of plague germs to the want1 misery and filthy condition was at once evident4 ,during ,august the mortality averaged four and even five hundred per day4 ,in ,september the daily mortality rose to #a1jjj4 ,so great was the terror of the populace that it became impossible to secure bearers of the dead1 to obtain nurses and attendants4 ,the dead were left in heaps upon the streets1 so that it became necessary to transfer to the city #gjj galley slaves1 who were required to remove the bodies4 ,these same galley slaves were even pressed into service as nurses4 ,the diseased were abandoned by friends and relatives1 and under such conditions it need not be wondered at that they received little or no attention from others4 ,food and water were denied to the unfortunates1 and when food was administered to the pesthouses it was thrown into the windows by machinery4 ,the disease continued in ,marseilles until ,december1 #agba1 but isolated cases persisted until ,april1 #agbb4 ,during the fifteen months of its duration it carried off #dj1jjj of the population4 ,according to ,defoe1 there died of the plague in ,marseilles and within a league of its walls #fj1jjj4 ,from ,marseilles the plague reached ,aix1 and in the winter of #agbj and #agba it carried off #ah1jjj of its people4 ,it also reached ,arles1 where1 in #agba1 out of a population of #bc1jjj1 #aj1jjj died 7forty-five per cent74 ,the same year1 in ,toulon1 which had a population of #bf1jjj1 the plague attacked #bj1jjj of the population1 and of these #ac1jjj1 or about one-half of the original population1 died4 ,the country districts about ,marseilles were likewise invaded4 ,out of a population of #bdh1jjj1 there died of the plague #hh1jjj1 or fully thirty-five per cent4 ,it is evident from this description that the plague of #agbj was in nowise inferior to that of #acdh4 ,fortunately1 the disease did not spread beyond ,provence4 ,it is noteworthy that in many instances1 in ,marseilles1 people secluded themselves in their houses1 avoiding all communication with the outer world1 and in this way escaped4 ,similar isolation of cloisters1 insane asylums1 likewise resulted in freedom from the disease which stalked so freely throughout the stricken city4 ,it was experience of this kind in isolation of the healthy which led ,defoe to write his #8,due ,preparations for the ,plague4' ,toward the middle of the century the plague reasserted itself in the ,danubian provinces1 the constant battleground between the ,turks and ,russians and ,austrians4 ,in #agch it not only prevailed in ,russia but also invaded ,hungary4 ,of more importance than this occurrence is the outbreak of the plague in #agdc in ,sicily4 ,the last epidemic of plague had occurred in ,messina in #afbd4 ,after a lapse of one hundred and twenty years1 it reappeared with terrible results4 ,in ,messina1 as in ,marseilles and in ,london1 the first cases were not recognized as plague cases and1 as a result1 the infection spread until1 like a veritable explosion1 the disease developed all over the city4 ,the plague1 with its attendant misery of lack of food1 and even of water1 was in vain combated by religious processions4 ,the plague corpses were in heaps in the streets1 as in ,marseilles1 and cremation was resorted to in order to effect their removal4 ,that year #cj1jjj died of plague in the city of ,messina4 ,with the exception of a slight epidemic at ,noja in #ahae1 this outbreak in ,messina in #agdc was the last one to appear in ,italy4 ,in #agee1 the plague was introduced into ,transylvania by an ,armenian merchant from the ,black ,sea4 ,before it was extinguished1 #d1cjj deaths were recorded4 ,next to that of ,marseilles and of ,messina1 the most noteworthy outbreak of plague was that which occurred in #agga in ,moscow4 ,the disease was introduced by troops returning from the ,danubian provinces4 ,as so often has been the history of plague1 the first cases were not recognized1 and the existence of pest was denied4 ,when the plague was demonstrated to be present1 it is said by ,haeser that three-fourths of the populace deserted the city4 ,the disease began early in ,march and increased during the early summer months4 ,in ,august over #g1jjj deaths resulted1 while in ,september the records show that #ba1jjj died4 ,in ,october the plague decreased1 but still #ag1jjj deaths attested to its fearful power4 ,early in ,january it became extinct1 after a duration of ten months1 and after having caused the death of more than #eb1jjj people4 ,toward the close of the eighteenth century1 at the time of the ,napoleonic invasion of ,egypt and ,syria1 the ,french armies came into contact with the plague4 ,bonaparte's visit to the pest-stricken soldiers at ,jaffa has been perpetuated in the historic canvas which is to be seen at ,versailles4 ,during the nineteenth century the plague ravaged ,northern ,africa on diverse occasions4 ,constantinople was invaded in #ahjb1 #ahjc1 #ahjh4 ,it was also present to a slight extent in the ,caucasus and in ,astrakhan4 ,a notable plague epidemic appeared in ,egypt in #ahab1 and soon spread through ,turkey and ,southern ,russia4 ,constantinople and ,odessa were severely scourged4 ,in ,odessa out of a population of #bh1jjj there died #ab1jjj4 ,it is a noteworthy fact that the ,napoleonic wars1 with all their incident hardships and misery1 did not develop or spread the plague in ,europe4 ,the outbreaks of the disease were limited during this period to ,africa and to ,turkey1 ,bosnia1 ,roumania1 ,dalmatia and to ,southern ,russia4 ,two exceptions1 however1 are to be noted4 ,in #ahab the ,island of ,malta was infected and more than #f1jjj of its people yielded to the disease4 ,the epidemic of #ahae at ,noja1 in ,apulia1 was the first recurrence of the plague on ,italian soil since #agdc1 and thus far it has been the last4 ,the ,balkan ,peninsula and ,southern ,russia were visited from time to time by the plague up to about #ahda4 ,for nearly forty years ,europe was wholly free from the disease1 which1 however1 continued its existence in ,northern ,africa1 in ,mesopotamia and in ,india4 ,the ,russo-,turkish war of #ahgh brought the ,russian troops into contact with the disease in the ,caucasus1 and the epidemic at ,vetlianka on the lower ,volga was unquestionably introduced by such returning soldiers4 ,such1 then1 has been the history of the bubonic plague4 ,no other epidemic disease can be traced authentically as far back as the #8,black ,death4' ,the characteristic symptoms1 the rapid death1 the excessive mortality are all features which have been noted through more than twenty centuries4 ,the plague bacillus discovered in #ahid by ,yersin1 judged by its effect1 is neither more nor less virulent than its early progenitors4 ,it has often died out in a given locality or country1 it has even been forced back to its original ancestral home1 but still the same type1 the same species has perpetuated itself unchanged4 ,if the plague on its present world-wide journey does not cause such terrible outbreaks as it has in the past1 it will be not because the germ has been altered by time1 but because man has changed in so far as he has slowly learned and profited by the lessons of previous epidemics4 ,,gasoline ,,automobiles4 ,,by ,,william ,,baxter1 ,,jr4 ,to understand the operation of a gasoline vehicle it is necessary to be somewhat familiar with the principle on which gasoline motors act4 ,briefly stated1 it is as follows3 ,the gasoline is converted into a vapor1 and in this state is mixed with a sufficient amount of air to cause it to ignite when heated to a proper temperature4 ,this mixture of air and vapor is admitted into a cylinder in which a piston moves freely1 this part being substantially the same as in a steam engine4 ,by means of an electric spark or a hot tube1 the mixture is ignited1 burning so violently as to expand the products of the combustion with such rapidity as virtually to become an explosion4 ,the force of this explosion pushes the piston to the further end of the cylinder1 and by means of a connecting rod and a crank this movement imparts a rotary motion to a shaft4 ,illustration3 ,,fig4 #a4 ,,gasoline ,,motor4 ,the entire operation is made perfectly clear by the aid of ,fig4 #a1 which is a simple diagram of a single cylinder motor4 ,the chamber ,r contains the gasoline4 ,air enters this chamber through tube b1 as indicated by the arrow1 and passes out between the plate c and the surface of the gasoline4 ,the float d keeps the plate c in the proper position regardless of the amount of liquid in the reservoir4 ,the heated gases exhausted from the cylinder pass through the pipe r1 and thus heat the gasoline so that it vaporizes freely and the air passing under c becomes charged with the necessary proportion of vapor4 ,the mixed air and vapor enter a valve chamber ,s1 from which the flow into pipe e is regulated by the movement of handle a4 ,in this chamber there is another valve1 operated by an independent handle1 and by means of this more air can be admitted into the mixture when desired4 ,through the pipe e and the valve f the vapor enters chamber ,q1 which connects with the top of the cylinder4 ,suppose the shaft ,g is rotating1 then the piston will be drawn down from the position in which it is shown and thus a vacuum will tend to form in chamber ,q4 ,this action will cause the valve f to open and the mixture of air and vapor will flow into ,q until the piston reaches its lowest position and begins to ascend4 ,at this instant the valve f will close1 and then the upward movement of the piston will compress the mixture in the chamber ,q4 ,when the piston reaches the upper position1 after completing the down and up strokes1 the lever l and the contact point p will come together1 and an electric current developed in the induction coil ,m will pass through the wires j and k and produce a spark at i between the ends of the metallic terminals passing through the plug of insulating material1 which is shown in dark shading4 ,this spark will cause the mixed air and vapor to ignite1 producing an explosion that will force the piston down for the second time4 ,on the second upward movement of the piston the gases produced by the combustion of the vapor will be forced out through the valve h into the chamber ,t and the pipe r4 ,the valve h and the lever l are operated by cams mounted on the shaft m1 and they are so set that the spark at i occurs when the chamber ,q is full of the explosive mixture and the piston is at the top of the cylinder4 ,the valve opens when the piston begins to move upward after the explosion has forced it to the bottom position4 ,as will be seen1 the piston must move down to draw in a supply of the explosive mixture2 it then moves upward to compress it1 and on the second down stroke it is pushed by the force of the explosion4 ,from this action it can be clearly realized that the power developed by the motor comes from the force exerted by explosions at every alternate revolution of the shaft4 ,on that account the cams that move the valve h and the lever l are placed on a separate shaft1 which is geared to the main shaft in the ratio of two to one2 that is1 the wheel ,k is twice the diameter of the wheel ,j4 ,as the force of the piston acts on the shaft only once in every two revolutions it is necessary to provide a heavy fly wheel ,o1 which will store up enough momentum to continue the rotation of the motor through the ineffective revolution4 ,before the motor can put forth an effort it is necessary for the piston to move downward so as to draw in a supply of explosive gases and then to move up so as to compress them and produce an explosion2 therefore1 the motor will not start of its own accord1 but must be set in motion4 ,in the act of starting the wheel ,o is turned by hand4 ,the combustion of the gasoline vapor within the chamber ,q and the upper end of the cylinder develops a large amount of heat1 and unless means are provided for dissipating it the temperature will soon rise to a point that will interfere with the proper action of the motor4 ,two ways are employed to carry off the heat4 ,one is by surrounding the cylinder with a water jacket1 as shown in the diagram at ,,nn2 and the other is to provide the exterior of the cylinder with numerous thin ribs so as to increase the surface exposed to the air and thus increase the radiation4 ,illustration3 ,,fig4 #b4 ,,petroleum ,,spirit ,,motor4 ,the electric spark is a very effective igniter for the explosive mixture1 and1 by properly setting cam n the explosion can be made to take place just at the position of the piston that may be found the most desirable2 but the points at i are liable to get out of order1 and the battery that actuates the induction coil ,m and the coil itself can become a source of more or less trouble1 and on that account the igniting is effected in some motors by means of a hot tube4 ,when this is used the cam n1 the lever l and the electrical parts of the apparatus are not required4 ,in their stead a tube is placed on the upper side of the chamber ,q and this tube is maintained at a red heat by means of a flame impinging against its outer surface4 ,when the explosive mixture is compressed it rises in the interior of the hot tube1 and when it reaches the portion that is hot enough to produce combustion an explosion takes place4 ,by many engineers this arrangement is regarded as superior to the electric spark on account of its simplicity4 ,gasoline motors are made with one1 two or more cylinders1 but in each cylinder the action that takes place is that described above4 ,the actual construction of a motor is not so simple as might be assumed from the appearance of ,fig4 #a2 many details are required which are not here shown4 ,a more perfect idea of the actual construction of a gasoline motor can be had from ,fig4 #b1 which is a working drawing of a recent ,european invention4 ,in this design it will be noticed that the cylinder is cooled by radiation into the surrounding air1 the exterior surface being increased by numerous circular ribs and also by extending a hollow trunk from the upper side of the piston1 so as not only to increase the radiating surface1 but also to allow the hot air to escape from the chamber ,t in which the crank discs revolve4 ,in this drawing ,e is the explosion chamber1 corresponding to ,q in ,fig4 #a1 and the valve s is the counterpart of f1 while s' corresponds to the valve h4 ,the upper pipe t is the pipe e of ,fig4 #a and the lower pipe t' is the pipe r of the same figure4 ,although the crank discs1 connecting rods and other details are different in shape1 it will readily be seen that their relation to each other is the same4 ,illustration3 ,,fig4 #c4 ,,reversing ,,mechanism4 ,since a gasoline motor cannot start of its own accord1 it is necessary in vehicles in which they are used so to arrange the driving gear that the motor may be kept in motion all the time and always in the same direction1 hence1 to reverse the direction of the carriage1 reversing mechanism1 independent of the motor1 must be provided4 ,the most simple mechanism for a gasoline vehicle employing spur gearing exclusively is shown in diagrammatic form in ,fig4 #c4 ,in this figure ,a represents the cylinder of the motor1 ,b the crank disc chamber and ,m the vaporizing receptacle1 which is generally called the carburator4 ,the pinion ,c1 on the end of the motor shaft1 meshes into a gear ,d which is mounted upon a sleeve ,e which revolves freely round shaft ,g4 ,this sleeve has its ends formed so as to engage with the gears mounted upon shaft ,g1 and by means of a lever1 which is not shown1 but which works in groove a1 the clutch either s or ss can be thrown into engagement with its corresponding gear4 ,if s is thrown into gear1 as shown in the drawing1 the wheel ,f will turn ,h and the pinion ,i will rotate the gear ,j which is mounted upon the axle of the carriage4 ,if the clutch ss is thrown into engagement1 the gear ,g will turn ,k and this wheel will turn l2 but1 as can be clearly seen1 the direction in which l will revolve will be opposite to its motion when driven through ,f and ,h1 therefore1 if when ,f drives the carriage runs forward1 when ,g drives it will run backward1 and when ,e is moved to the central position1 so that neither s nor ss engages with their respective gears1 the vehicle will stand still1 but the motor will continue to revolve4 ,illustration3 ,,fig4 #d4 ,,plan ,,and ,,elevation ,,of ,,underberg ,,motor ,,voiturette4 ,this diagrammatic arrangement is more simple than the gearing actually used and is not as complete in action as many of the devices1 as it only provides means whereby the direction of rotation of the axle may be changed1 while in many carriages the gearing also varies the ratio between the speed of the motor and the driving wheels4 ,it is also quite common to combine in the train of gearing spur gears and sprocket wheels1 and in some instances even belts4 ,fig4 #d illustrates a ,french gasoline automobile made by ,underberg1 of ,nantes4 ,the first figure is a side view1 and the second is a plan of the truck and driving mechanism4 ,illustration3 ,,fig4 #e4 ,,cherrier ,,two-,,speed ,,gear4 ,the motor1 which is of the single cylinder type1 cooled by radiation into the air1 is located at ,n4 ,the pinion on the end of the motor shaft engages with the wheel on the end of shaft ,a4 ,this shaft carries four gears1 which can be moved by means of lever ,c1 so as to engage with corresponding gears on shaft ,b1 thus providing four different speeds4 ,the motion of ,b is transmitted to the rear axle by means of a belt that runs over the pulleys p and ,p1 the latter being carried by a differential gear1 so as to run the two driving wheels at proper velocities4 ,the circular ribs surrounding the motor cylinder are well shown in the figure1 in which the carburator of ,c is also seen4 ,the housing for the motor is open at the sides so as to give air currents free access4 ,in ,fig4 #d the speed changing gears are shown1 the reversing train being omitted2 but if it were also drawn in1 the diagram would be far more elaborate than ,fig4 #c4 ,another form of variable speed gear is shown in ,fig4 #e4 ,this provides for two speeds4 ,the large wheel ,e is on the carriage axle1 and it is driven either by a pinion ,f1 or by ,j4 ,upon the shaft ,o there are two friction clutches ,c ,d1 and when ,c acts the pinion ,f drives ,e1 and when ,d acts the pinion ,g drives ,h1 which in turn drives ,i1 and this wheel is mounted on the same shaft as ,j4 ,some of the best-known makers of gasoline vehicles do not employ variable gears and depend for changes in the speed wholly upon variation in the velocity of the motor4 ,the ,de ,dion carriages are made in this way1 the gearing being substantially as illustrated in ,fig4 #c4 ,illustration3 ,,fig4 #f4 ,,panhard ,,levassor ,,vehicle4 ,illustration3 ,,fig4 #g4 ,,motor ,,of ,,vehicle4 ,fig4 #f shows a gasoline vehicle made by ,panhard ,levassor1 who are perhaps the best known ,french manufacturers of automobiles1 as their vehicles have been the winners in all the notable races held within the past few years4 ,the motor they use is shown in ,fig4 #g1 and1 as can be readily seen1 is of the two-cylinder type1 cooled by a water jacket1 just as in ,fig4 #a4 ,the explosion is produced by means of a hot tube1 as explained in connection with the last-named figure4 ,this motor is placed under the body of the vehicle1 and is connected with the rear axle by means of a train of gearing which terminates in sprocket wheels and chains that connect with driving wheels1 each one being operated by a separate chain4 ,in ,fig4 #f the sprocket wheel and chain are well defined1 and forward of these can be seen the outline of the casing enclosing the gearing4 ,illustration3 ,,fig4 #h4 ,,general ,,view ,,of ,,renault ,,voiturette4 ,illustration3 ,,fig4 #i4 ,,plan ,,of ,,the ,,truck4 ,illustration3 ,,fig4 #aj4 ,,variable ,,speed ,,gear4 ,fig4 #h shows another ,european design1 in which a variable-speed gear is used4 ,the plan of the truck1 showing the general arrangement of the mechanism1 is presented in ,fig4 #i1 and the details of the variable-speed gear are shown in ,fig4 #aj4 ,the motor is located at ,a1 and through a friction clutch ,b1 and the variable speed gear ,c1 it rotates the shaft ,h1 which runs lengthwise of the vehicle4 ,motion is imparted to the hind axle by means of bevel gears contained within the casing ,d4 ,the large bevel gear on the axle is of the differential type1 so as to drive the wheels ,r ,r at the proper velocities4 ,when a high speed is desired1 the variable speed gear1 ,fig4 #aj1 is set so that shaft ,m drives ,n direct1 the clutch at ,e being moved so as to interlock4 ,n is the end of shaft ,h1 so that with this connection the bevel pinion1 which meshes into the axle gear at ,d1 revolves at the same velocity as the motor shaft4 ,by moving the handle ,v1 ,fig4 #i1 to the right1 an intermediate speed is obtained1 and by moving it to the left1 the carriage is run at the lowest velocity4 ,when the handle ,v is turned to the right1 the ends ,m and ,n1 which form the clutch ,e1 ,fig4 #aj1 are separated1 and at the same time the lower shaft ,h is moved toward ,m1 so as to cause gear #a to mesh into gear #b1 and also #c into #g4 ,by this means the end ,n of the axle-driving shaft is rotated through the train of gears #a1 #b1 #c and #g4 ,if the handle ,v is turned to the left1 the shaft ,i is moved toward ,m1 so as to cause gear #a to mesh into gear #d1 and gear #f into #h1 the latter being secured to end ,n of the axle-driving shaft4 ,the speeds obtained by these changes are in the ratio of nearly #a1 #b and #d4 ,illustration3 ,,fig4 #aa4 ,,plan ,,of ,,the ,t,,rgan-,,foy ,,voiturette4 ,fig4 #aa shows the plan of a light ,french carriage1 which is equipped with a double cylinder motor1 set in a horizontal position above the front axle1 and arranged to impart motion to the hind axle by means of belts4 ,the motor1 which is located at ,a1 turns a vertical shaft1 and this1 through spur gears1 rotates a horizontal fly wheel1 ,b4 ,two pulleys are mounted upon the motor shaft1 and from these belts run to tight and loose pulleys on a countershaft1 ,s4 ,from the latter the rear axle is driven through two sets of spur gearing1 which give two different speeds4 ,by means of the belts1 two other speeds are obtained1 thus giving1 in all1 four different velocities4 ,to stop and start1 the belts are shifted from the tight to the loose pulleys by a belt-shifter1 f4 ,at h1 a muffling chamber is located1 into which the motor exhausts1 so as to reduce the noise4 ,the elevation and plan of one of the celebrated ,french racing-machines1 the ,valle car1 is shown in ,fig4 #ab4 ,the motor of this machine is of sixteen horse-power capacity1 has four cylinders1 and is connected so as to impart motion to the hind axle by means of a single wide belt1 which is marked ,g in both the line drawings4 ,the driving-pulley on the motor shaft is located at ,h1 and the axle pulley at ,h'4 ,within the latter there is a train of gears for reversing the direction of rotation of the axle1 and also for obtaining the differential velocities of the two driving wheels4 ,there is no mechanism for variable speed1 this being obtained wholly by changes in the velocity of the motor4 ,the motor speed can be made to vary through a wide range by using four cylinders1 with which it is possible to reduce the velocity so low that it would be likely to bring the machine to a standstill if provided with one1 or even two1 cylinders4 ,the change in the motor velocity is obtained in part by the action of a governor located in a chamber at ,a1 and in part by the action of the electric ignition device which is arranged so that the time when the spark is produced can be varied4 ,the rear axle is so held that it can be moved through a short distance1 horizontally1 by manipulating the lever ,d1 and in this way the belt ,g can be made tight or loose1 thus affording another means for varying the speed4 ,a brake is provided which presses against the inner side of the axle pulley1 ,h4 ,this brake is used ordinarily1 but in the case of an emergency another brake can be operated which presses against the outside of the wheel in the space between the two sides of the belt4 ,it is claimed for this vehicle that by the elimination of mechanical speed-changing devices1 a great deal of weight is saved1 and that this is more than enough to compensate for the extra weight of the motor1 arising from the use of four cylinders4 ,in most gasoline carriages it is necessary to provide a slow-speed gear for hill-climbing1 as the motor cannot put forth a sufficient effort to ascend a steep grade at the normal velocity4 ,with this racing-machine such a gear is not required owing to the enormous power of the motor4 ,illustration3 ,,fig4 #ab4 ,,elevation ,,and ,,plan ,,of ,,vallee ,,car4 ,there are quite a number of gasoline automobiles manufactured in this country1 and1 as in the case of the steam and the electric carriages1 they compare most favorably with the best ,european products1 in so far as the artistic effect is concerned4 ,that such is the case can be realized at once by an examination of ,figs4 #ac and #ad4 ,we regret our inability to illustrate the mechanism of these vehicles1 but the truth is1 that the manufacturers appear to be unwilling to make public the details of their designs4 ,in the phaeton shown in ,fig4 #ac1 a single-cylinder motor is used1 and it is so arranged that it can run at different velocities1 so that no variable speed mechanism is required1 except a single train of gears1 which is thrown into action when running uphill4 ,the motor itself can be run at any velocity from #bjj to #hjj revolutions per minute1 thus giving a speed variation of four to one4 ,a carriage of this make competed in the last international automobile race from ,paris to ,lyons1 ,france1 and although it failed to come in first1 it made a remarkable showing1 which might have been considerably improved if it had not been for an accident which compelled it to retire from the contest4 ,illustration3 ,,fig4 #ac4 ,,winton ,,phaeton4 ,illustration3 ,,fig4 #ad4 ,,oakman ,,vehicle4 ,the vehicle shown in ,fig4 #ad is of small size and light construction1 although amply strong for the purpose for which it is intended4 ,the power of the motor1 which is located under the seat1 is transmitted through friction wheels4 ,in looking at the illustration it will be noticed that the hind wheels have a circular rim attached to the inner side1 and of a diameter somewhat smaller than the wheel itself4 ,two small friction wheels are placed so that either one may be pressed against the inner surface of this rim4 ,the shape of the rim1 as well as that of the small wheels1 is such that they hug each other firmly1 so that the rim is carried around in a direction which corresponds with the direction of rotation of the friction wheel4 ,in operating the carriage the motor is set in motion1 and then one or the other of the two friction wheels is pressed against the rim on the driving wheel1 according to whether it is desired to run forward or backward4 ,while this arrangement might not operate with entire success if applied to a heavy vehicle1 it appears to be all that could be desired for a light carriage4 ,three-wheel vehicles have been used1 but there is a difference of opinion as to their value1 as the construction has disadvantages as well as advantages4 ,it is evident that such a vehicle can be steered with greater ease than one running on four wheels1 but on country roads1 where the wagon wheels roll down a smooth surface1 and leave the space between in a rough condition1 it is equally evident that the third wheel1 in passing over this uneven surface1 would jolt the vehicle to a considerable extent4 ,on a smooth pavement the three-wheel vehicle will run fully as well as the four-wheel2 but1 on the other hand1 on such a pavement the latter can be steered with as little effort as the former1 so that the question of superiority of design is one that probably depends upon individual taste4 ,from the descriptions of automobiles given in this and the two preceding articles1 it will be seen that although many of them are used1 especially in ,france1 they are not entirely free from objectionable features4 ,the electrical vehicles are provided with the most simple and durable machinery1 and1 being noiseless1 odorless and free from smoke1 are all that could be desired in so far as their operation is concerned2 but they are heavy and can only be used in places where the batteries can be recharged4 ,the steam vehicles are light1 have simple mechanism and can run anywhere2 but they exhaust steam into the air1 which is clearly visible in cold or wet weather1 and the heat from the engine and boiler is an objection1 at least in summer time4 ,the gasoline vehicles run well1 but are noisy1 and the odor of the gasoline is disagreeable as well4 ,,some ,,scientific ,,principles ,,of ,,warfare4 ,,by ,,william ,j4 ,,roe4 ,as in boxing1 fencing1 saber and bayonet exercises1 there are comparatively few postures1 guards1 thrusts and strokes1 so in warfare1 whether the numbers be large or small1 the arms most modern or ancient1 there are just a few principles to whose steady adherence and skilful manipulation all success is due4 ,in order that these may become apparent without irksome study of military details1 let us imagine a command of say a thousand men1 fairly well drilled1 of good ordinary intelligence and engaged in a cause worthy of being fought for4 ,we have been in camp for some time1 but an order has now come to join the main army4 ,this is a long distance off1 the railway communications have been broken1 and the intervening country1 though possessed of good roads1 is more or less in the hands of the enemy4 ,our scouts have kept us informed as to the condition of the country for several miles around2 our first day's march is1 therefore1 not hampered with any especial dread of surprise4 ,we move quickly and at ease4 ,safe as everything appears to be1 the commander relaxes none of the needful precautions2 at least fifty men1 under command of an experienced officer1 are sent quite far to the front1 the distance varying with the nature of the country--the farther1 the more broken it may be4 ,the best roads are followed2 the men are allowed to march at ease1 though always preserving-their company organization1 while the officers are always more or less on the alert4 ,there is a small rear guard1 but it is upon the advance that the main responsibility falls4 ,of the fifty thrown forward1 about half will remain together2 the rest are scattered2 some far to the front along the highway2 others on either side of the route1 riding up the hills on either hand1 making sure that no deep gorge1 dense growth of forest or thicket1 nor even a field of grain conceals an enemy4 ,it is upon the alertness of those vedettes on front and flanks that the safety of the force in great measure depends4 ,history records many relaxations of this principle of precaution1 and for lack of it sudden ambushes and deplorable disasters4 ,it was thus1 in spite of ,washington's repeated warnings1 that ,braddock fell into a cunning ambuscade1 and thus 7not to multiply examples7 that ,custer and his command were massacred to a man among the high ,rockies4 ,on the annexed map the men may be located at #8,a' marching from #8,d' in the direction of the village1 #8,f'4 ,the advance is at #8,b'1 the rear guard at #8,c'4 ,the commander rides with the main column1 near the front4 ,the black dots1 with pennons1 indicate the general position of the vedettes at this point1 though1 of course1 they are continually advancing4 ,the commander has noted on his map a foot path1 beginning at #8,d'1 leading over the rugged hills4 ,by taking this path a considerable distance could be saved2 but it is quite impracticable for the wagons1 and the troops1 therefore1 continue along the high road4 ,the valley is gently undulating1 with a gradual slope from the low hills towards the stream4 ,illustration ,the projecting hills near the head of the column form an especially dangerous point4 ,what easier than for an enemy to plant batteries here on either side of the road4 ,a sudden1 heavy fire would throw a negligent force at once into disorder2 a situation to be taken instant advantage of by a vigorous adversary2 a charge of horse concealed behind the hill at #8,o'1 and nothing might be left except flight1 with great loss of life1 and surrender with loss--if not of honor1 at least of reputation as a safe leader4 ,happily1 we shall avoid both alternatives4 ,our scouts have explored most thoroughly every possible vantage ground4 ,they have not been content with any mere glances2 their instructions are to take nothing for granted4 ,that field1 marked #8,g'1 looks innocent enough1 but the tall1 thick rye or corn may cover a skilfully placed battery4 ,the plot marked #8,m' may be simply a vineyard2 but it does no harm to inquire4 ,the inhabitants of the country are friendly1 and1 therefore1 the chances are not favorable to this sort of surprise2 but in war it is often not the likely1 but the unexpected that happens2 the commander who knows his business guards against the remote possibility4 ,though we have imagined a force of a thousand1 it must not be lost sight of that the same kind of precautions should be employed for very much larger numbers2 indeed1 you need only alter the scale of the map1 imagine additional roads1 a railway line or two1 increase to thousands1 if necessary1 the fifty of our vanguard1 and the result is but an application of the very first principle of warfare3 ,eternal vigilance is the price of safety as well as of liberty4 ,the troops have been in camp for some time2 their condition is excellent for a long march4 ,as the corn and rye are not yet gathered1 the time is early summer4 ,the roads are in prime condition4 ,they set out by sunrise and halted for perhaps two hours at noon4 ,it is by thus sparing his troops during the heat of the day that the colonel will have a body of men fresh enough at nightfall to march1 if necessary1 all night4 ,but no such urgency exists2 it is nearing sunset1 and preparations are now being made to encamp4 ,by his map the colonel has informed himself in the matter of distances1 and has decided that they shall pitch their tents somewhere in the vicinity of the village 7#8,f'74 ,the scouts report an eligible location for camp at #8,s'1 and this is finally chosen4 ,it has several advantages1 being comparatively level1 and yet upon high ground1 and has in close proximity several wells of good water4 ,the train containing provisions and ammunition is parked in the safest locality1 the horses picketed1 and the guns--perhaps two or three field pieces and machine guns--placed where they can be most easily handled4 ,by all means1 give the men as good a supper as the neighborhood affords4 ,it will be wise not to encroach upon the rations1 but rather draw supplies from the village2 there are1 no doubt1 purveyors of one sort or another to be found ready enough to supply us1 the more so that they will be amply paid4 ,refreshed by their supper the men are ready to turn in at tattoo2 by the time #8taps' have sounded most are soundly sleeping4 ,but some are awake2 if doing their full duty1 wider awake than ever they are likely to be in times of peace4 ,the same attention to the bodily comfort of his men which impelled the colonel to give them a long rest at midday and a comfortable meal1 applies with increased force to those detailed early in the morning for the night's guard2 during the march these have been spared as far as possible1 even being allowed a lift now and then in an ambulance4 ,such privileges are not granted by a commander who knows his craft as a concession to the laziness1 but rather as a preparation for the effectiveness of his men4 ,this is a principle of action1 and may apply to business as well as war1 that the strong head never withholds reasonable and proper indulgence2 the better1 it may be said1 to enforce at needful times reasonable and proper exertions4 ,as soon as the camp is established the guards are posted4 ,if great precautions were needed during the day1 much more are they by night4 ,if fifty were sufficient on the march we need a hundred during the hours of darkness4 ,in the case of a large army an elaborate system of night guards is necessary3 ,first1 #8advanced guards'1 occupying strong positions at some distance from the main body2 beyond these are the picket guards2 further still towards the front what are called #8grand guards'1 from which are thrown forward the outposts1 to which the line of sentinels is directly attached4 ,in case of alarm1 the sentinels fall back upon the outposts2 these upon the grand guards2 they1 in turn1 if necessary1 upon the pickets2 the necessities of the case and the strength of the enemy's demonstration determining the movements of the defense1 even perhaps to the #8long roll' and rousing of the entire army4 ,in our case1 no such elaborate system is possible2 we content ourselves with outposts and the line of sentinels1 all that will be needed1 if vigilant1 to guard against surprise4 ,the colonel1 attended by the officer in command of the guard1 will select the sites for outposts4 ,these1 five in number1 are marked by stars upon the map4 ,the direction from which an attack is most probable is from the ridge 7#8,r'1 #8,r'74 ,the men are usually on the sentinel line for two hours at a time1 with opportunity for four hours' sleep2 that is1 with shifts1 or1 as they are called1 #8reliefs' of three parties1 two hours on and four off4 ,this is not1 however1 invariable1 it being sometimes wiser to relieve the men oftener or not so often1 this being regulated by circumstances--the state of weather1 distance of posts apart1 fatigue of the men1 etc41 etc4 ,the sentinels will be posted on clear nights generally upon high ground2 in bad or foggy weather the foot of the slope is preferable4 ,the officer will see that no obstacle prevents the sentinel from retreating upon his outpost if attacked4 ,the men will be directed to take advantage of any cover that offers1 always to keep in easy touch with one another and watchful1 never to raise a false alarm1 but quickly and decidedly a real one1 and while not failing to discover the meaning of anything unusual in their front1 never to expose themselves from mere bravado4 ,what measures shall be taken in case of an attack in force must1 of course1 depend entirely upon circumstances4 ,a night attack1 intended merely as an annoyance1 or #8feeler'1 or at most to stampede some of the cattle1 or to gather information as to strength1 resources1 etc41 is quite a different affair from one planned for the purpose of complete victory1 either the destruction1 dispersal or capture of the command4 ,a mere night foray is generally executed by comparatively few4 ,the opposing chief may be desirous of getting information concerning the force that his scouts have reported is advancing down the valley4 ,a little expedition like ours sometimes serves as a disguise for a momentous strategical movement4 ,the chief determines to find out all he can as to our purpose4 ,he has found us vigilant by day2 he resolves to try what the night may disclose4 ,this sort of surprise is apt to produce better results than the project of some dashing subaltern1 anxious for the bauble reputation4 ,for such an attack an hour near midnight is usually selected1 that the information may be gathered or the mischief done and a retreat effected under cover of darkness4 ,a dark1 wet1 blustering1 or--if the time be winter--an especially cold night is chosen4 ,the degree of success to be attained depends naturally upon the element of surprise4 ,unless this be complete the attacking party will find their attempt usually quite futile4 ,the other sort of attack--that which has for its object the capture of the position--is usually planned to take place during the extreme darkness just preceding daybreak4 ,the enemy has perhaps crawled on hands and knees up the slopes towards the line of sentinels4 ,the van of this force is composed entirely of picked men1 officered by the coolest heads4 ,signals are agreed upon1 exact times for action arranged1 and everything calculated to a nicety to insure that suddenness which is the very soul of success4 ,it is in the planning of such an expedition that true qualities of generalship are shown4 ,it is the fashion rather to decry the military merits of ,washington2 yet ,i know of few events in history that show more sagacity than the swift crossing of the wintry ,delaware and the surprise of ,trenton4 ,it was sagacious chiefly for the accurate comprehension of the probabilities4 ,washington knew the convivial habits of ,rahl's ,hessians1 especially at ,christmas-tide2 he reckoned upon finding them in the midst of carousals1 and the result proved the value of his forethought4 ,under ordinary circumstances1 on the march1 to quarter a command inside four walls is never advisable4 ,the men are not as readily under the eye of their officers2 in case of surprise they cannot be called into the ranks as quickly2 discipline insensibly relaxes1 and the machine 7for an armed force ought to be that1 however intelligent its units7 fails to respond instantaneously to the word of the chief4 ,in case of a serious attack1 however1 the village may serve a most important purpose4 ,should the houses be substantial ones of stone or brick1 each may become a most efficient1 if temporary fortification4 ,one consideration which might have prevented its occupation has now no longer any weight4 ,apart from any natural feeling of good will for our fellow citizens1 how unwise it would be to unnecessarily exasperate them4 ,but now in the face of the enemy1 it will be surprising if any soul is churl enough to grudge a patriotic hospitality4 ,most of the denizens will1 indeed1 make haste to hide their precious persons in the cellar1 but will seldom grumble at the necessity4 ,with the utmost celerity the baggage and horses are moved to the most sheltered spot2 the guns1 under strong guards1 posted where they may be best utilized2 some of the men1 previously detailed for just such an emergency1 are engaged in throwing up earthworks1 piling logs1 stones1 anything that can be utilized for barricades4 ,the officer charged with that duty1 if possible a skilled engineer1 goes quickly from place to place1 hurriedly indicating the lines of defense2 these connecting the several buildings in such a manner as to enclose the entire command within lines of quite formidable intrenchments4 ,all this time the troops1 having taken possession of the houses1 have poured an uninterrupted fire upon the assailants1 obliging them to retire1 or at least giving the diggers--or sappers1 as they are called--time to complete their labor of defense4 ,surrounded by a force sufficiently large to make resistance in the field quite hopeless1 we are at least in position to protract the struggle1 and one capable of defense1 except against an assault in overwhelming numbers1 or against heavy artillery4 ,the latter they are not provided with1 or the measures we are taking might all go in the end for nothing4 ,several assaults are attempted during the day1 but are easily repulsed with no small loss4 ,the enemy at last withdraws1 and we now see that he is busy throwing up intrenchments4 ,meanwhile1 we have not been idle4 ,to facilitate communication1 and to enable us to concentrate our forces under cover1 passageways have been constructed between the various buildings1 inner partitions preventing free access from room to room within the houses have been broken through1 and the dbris1 together with beds broken up1 mattresses and #8any old thing' capable of arguing with a bullet1 piled in the window embrasures1 leaving loopholes here and there1 as occasion offers1 while galleries may be constructed with loopholes in the floor to fire downwards4 ,illustration3 #b ,one of the most important matters to be attended to is the securing of as many good positions as possible1 from which fire may be concentrated upon exposed points4 ,in a regular siege the points of attack selected will always be those most exposed1 on account of their projecting beyond the line of defense4 ,in the case of a village like this resisting an attempt at capture the principles are identical2 it will certainly be the points that project that will be danger spots and which will therefore require especial attention4 ,illustration3 #c ,you observe on the enlarged map of the village that there are double lines between the outer buildings2 these are the improvised intrenchments4 ,notice that they have not been constructed flush with the face of the outer walls in any instance2 but always considerably retired4 ,the object of this arrangement is more effectually to defend the barricades4 ,in the annexed sketch 7,no4 #c7 #8,a' and #8,b' represent the two adjacent buildings and the lines #8,,cd' the breastwork4 ,in the buildings are windows--#8,e' and #8,f'--from which a heavy fire can be concentrated upon the assailants1 as may be seen from the direction of the arrow heads4 ,on the outer line are several projecting1 and1 therefore1 especially exposed points2 such as those at #8,a'1 #8,b' and #8,c'4 ,the arrow heads show the direction of protective fire4 ,as additional protection1 it might be wise to hold the two buildings 7#8,h'1 #8,h'7 outside the village4 ,if not held1 they ought1 if possible to be destroyed1 as also those marked #8,,jj'1 not included in the defensive lines1 as they offer excellent cover for the enemy4 ,the utmost care should be taken to provide a safe magazine for the ammunition and to cover well the place selected for a hospital4 ,the wagons and horses would be best protected in the space marked #8,,lll'4 ,should our defense prove too obstinate for direct assault1 it may be that the enemy will construct regular intrenchments from which to dig a trench deep enough to protect1 and large enough to hold a body of troops1 thus enabling them to approach sufficiently near to assail some weak point1 without too great risk4 ,the modern repeating rifle1 dangerous at a thousand yards1 and fatal at a hundred1 has given the defense so great preponderance that it requires quick work indeed to capture a stronghold4 ,observe the broken lines #8,,of and #8,,pf'2 these show the direction of possible trenches dug by the enemy4 ,but #8,,of' would be raked by the fire from the outlying house1 #8,h'2 the other is1 therefore1 the only feasible mode of approach4 ,the principle of defense1 shown by the direction of the arrow heads in the case of the beleaguered village1 is applicable to all conditions where ramparts are used4 ,suppose the command whose fortunes we have followed had been attacked while on the march at the point #8,a' on ,map #a4 ,the opposing force was manifestly too strong for resistance in the field2 they retreat to the rocky eminence #8,k' and there proceed to fortify the position4 ,a glance at ,diagram #d will show what they will try at least to accomplish4 ,in military language that shaded portion of the work to be constructed is called a bastion2 it consists of two faces 7#8,,ax' and #8,,ay'71 and the two flanks 7#8,,jy' and #8,,hx'74 ,the faces of this bastion are defended 7as the arrow heads indicate7 by the flanks of adjacent bastions2 that is1 the face #8,,ay' is swept by a raking fire from #8,,ze'1 and the face #8,,ax' from #8,,fg'4 ,reciprocally1 #8,,hx' rakes the face #8,,bg'1 and #8,,jy' the face #8,,ed'1 and so on round the intrenchment4 ,illustration3 #d ,all that has been said as to protecting the ammunition and stores will apply to this work as it did to the village4 ,if a spring of water can be included1 as at #8,o'1 this will be found of incalculable advantage4 ,of all forms of defensive ramparts the straight line is the worst2 if time does not permit a work with bastions1 however irregular1 an enclosure shaped somewhat like a star is serviceable 7shown in ,diagram #f1 ,figs4 #8,a'1 #8,b' and #8,c'74 ,should an enclosed work be impracticable1 the line should have its ends 7or #8flanks'7 strongly guarded1 and be broken up1 as in ,diagram #e #8,d' into short straight lines nearly at right angles1 to serve for mutual support4 ,this principle of mutual support1 however achieved1 is called that of #8defensive relations'1 and is capable of adaptation to all kinds of defensive works1 whether of a few men beleaguered in an improvised fortification1 a considerable number in a scientifically constructed work--permanent or field fortification--a fortress with an entire army behind its ramparts1 or a cordon of forts surrounding a great city4 ,illustration3 #e1 #f ,the ground plan of the work having been decided upon and staked out the men start in with pick and shovel1 digging1 if possible1 a ditch1 and throwing the material into the shape of the shaded portion of ,diagram #g4 ,the ditch1 outside the fort1 indicated by the figure #8,,fghj' serves the twofold purpose of getting material for the parapet #8,,abcdef'1 and for embarrassing an enemy in any attempt at assault4 ,to further embarrass him every sort of obstacle that may be at hand should be put to use--trees1 butts turned our way1 boughs interlacing2 stakes driven deep into the soil close together2 barbed wires wound in and out2 in short1 every expedient that may delay his advance and keep him as long as possible exposed to our most effective fire4 ,illustration3 #g ,the drawing 7#g7 was made with no attempt at exactness of proportion1 and simply to show the essentials2 the slope #8,,ef' is made as steep as the nature of the soil will permit2 #8,,de' slopes enough to enable a soldier standing upon #8,,bc' to fire upon an enemy entangled among the obstacles at #8,j'1 but never enough to weaken the mass of earth at and near #8,d'4 ,observe how common-sensible all these arrangements are2 not one too many or too few2 just the things that a practical man1 if he could think as he felt1 would do if suddenly called to command with an enemy advancing upon him4 ,unfortunately1 perhaps1 for the purposes of a patriotic and peaceful people1 men are inclined1 even though brave as courage itself1 to get nervous or nerveless in the immediate presence of danger4 ,this is the reason1 rather than for any especial erudition involved in war's art1 that we need trained soldiers--men trained to think mechanically and to act automatically amid the uproar of battle4 ,illustration3 #h ,we have carefully1 if briefly1 considered the requirements of the first maxim of strategy--,,caution--the need of it1 and the practical methods of securing it2 and also of the second maxim--,,defensive ,,relations--their necessity1 and how to secure them4 ,it now remains to consider the meaning of that phrase1 #8turning a position'1 or #8flanking' an enemy1 as to which of late we read so much in the daily press4 ,the map 7marked #h7 gives an idea of a section of country where two armed bodies meet under conditions that permit one flank to be completely guarded from attack2 these are the left flank of the force #8,a'1 and the right flank of #8,b'4 ,both rest upon a lake or broad river4 ,a steep precipice or deep morass1 as at #8,h'1 would serve as well4 ,suppose our force has advanced from the direction #8,c'1 the enemy down the road from #8,e' to #8,g'4 ,soon they form opposed lines facing each other1 the reserve somewhat to the rear and sheltered by some inequality of ground1 the #8thin blue line'1 almost1 but not quite1 touching elbows1 stretched along the crest of the ridge in front1 taking advantage of every chance to protect themselves--trees1 stone walls1 ditches2 kneeling1 crawling1 lying face down1 eyes along the rifle barrel1 finger on trigger1 keen and murderous1 but prudent1 and parsimonious of life4 ,the solid formations1 such as went out of vogue with old-time weapons1 would melt away before machine guns and ,krag-,jrgensens like frost before an ,august sun4 ,it seems as if all chivalry had departed2 it has but changed its ways4 ,the object of #8flanking' a position is to so manage as to turn that attenuated line into a mass of men upon which to let loose with dire effect either the quick-firing guns or the sharp edges of our horsemen's sabers4 ,notice those long1 bent1 black lines1 bending like fish hooks4 ,the arrow heads indicate the direction of a flanking attack2 from #8,f'1 through the woods1 up the ravine1 to fall upon the exposed end of the enemy's front at #8,k'4 ,such would be our most feasible method of flanking2 the foe might1 however1 have anticipated us1 either by providing a bloody hospitality somewhere in that ravine1 or by a flank movement of his own1 as the bent black line shows1 around the woods1 to fall upon our right flank at #8,f'4 ,such an operation1 if successful for them1 would be utterly disastrous to us4 ,surprised by a sudden and unexpected attack upon the weakest point and unable to change front in time1 men lose heart1 forget discipline1 huddle in masses1 confused and disorganized1 or fly like sheep1 in either case food for firearms1 gluttonous of such occasions4 ,it requires sometimes but a very small force upon a flank to produce great results2 the appearance upon the field1 even at a distance1 of ,joseph ,e4 ,johnston's corps at the first ,bull ,run was sufficient to demoralize the whole ,union army1 and at the battle of ,arcola1 ,bonaparte completely flanked the ,austrians with a few flourishes of his trumpets4 ,so we have for a third maxim of war the necessity of ,,protected ,,flanks4 ,if we know or think that a ,johnston lurks on either hand1 we ought to be sure of our ,pattersons2 if we apprehend an unfriendly visit from a ,blucher1 we should see to it that our ,grouchy is trustworthy4 ,let us now broaden our view of operations1 that we may see how the principles established for a limited number of men on the march1 in the field1 or behind fortifications1 may apply upon a larger scale4 ,to this end a brief study of the map 7#i7 will show four contiguous countries--#8,a'1 very populous1 powerful and wealthy1 having a navy capable of control of the high seas1 and a large and efficient army2 #8,c' represents a country even more populous1 but not aggressive1 #8,d' an insignificant power1 while #8,b' is a country considerable in extent1 but largely mountainous1 and sparsely inhabited by a rude but warlike people4 ,a cause of war comes up between #8,a' and #8,b'4 ,in ancient times the ruder nation would have been the aggressor1 tempted by the wealth and invited by the enervated populace of the larger civilization4 ,now the conditions are likely to be reversed4 ,however1 war begins2 the forces of #8,a' move hastily towards the frontier1 while his fleet blockades #8,b's' solitary seaport at the point #8,e'4 ,the maxim of ,,caution now naturally expands2 instead of information culled by a few daring riders from a narrow circuit1 it should be made to embrace the widest area of country and the utmost latitude of information--the condition of the enemy as to armament1 resources1 position of forces1 possible disaffection among the people--everything4 ,in war no item comes amiss4 ,the wealthier country will here have a manifest advantage2 it can afford to hire spies1 and can even 7as ,england did during the ,revolution7 purchase the treason of some disaffected chief4 ,caution for the lesser country will--if good generalship prevails--take the shape of occupying and strengthening the natural strategic positions4 ,these are nothing but flanks of a bastion on a large scale4 ,upon the map round black dots represent strategic positions along the frontier4 ,they are points susceptible of thorough fortification which control the several passes in

city1 the railway line or the adjacent rivers would furnish #8,a' with a practical base2 his line of advance would be in the direction #8,,fg'1 called the #8line of operations'2 #8,g'1 a fortified pass1 the proximate1 and #8,j'1 the capital of #8,b'1 the ultimate objective point of the campaign4 ,but it will be noted with what facility a determined enemy could fall upon #8,a's' communications from the point #8,h'1 which would also be the case were the advance made from #8,k' towards #8,l'4 ,of course1 in the end1 the larger resources will prevail2 but it may be that #8,a'1 baffled and

results of these coperating factors of degeneracy have stopped short of the extremes that might have been expected in a land of earth-despisers4 ,buddhism in its orthodox ,chinese form is radically

formidable rivals4 ,,religious ,,beliefs ,,of ,,the ,,central ,,eskimo4,b ,,by ,,professor ,,franz ,,boas4 ,b ,a description of the religious beliefs of the ,central ,eskimo1 based upon observations made by the writer1 was published in the ,sixth ,annual ,report of the ,bureau of ,ethnology4 ,the following account embodies observations which ,capt4 ,james ,s4 ,mutch1 of ,peterhead1 ,scotland1 following a suggestion of the writer1 had the kindness to make4 ,the material for this study was collected by ,capt4 ,mutch during a long-continued stay in ,cumberland ,sound4 ,the ,eskimo who inhabit the coasts of ,arctic ,america subsist mainly by the chase of sea-mammals1 such as seals of various kinds1 walruses and whales4 ,whenever this source of supply is curtailed1 want and famine set in4 ,the huts are cold and dark--for heat and light are obtained by burning the blubber of seals and whales--and soon the people succumb to hunger and to the terrors of the rigorous climate4 ,for this reason the native does everything in his power to gain the good-will of the sea-mammals and to insure success in hunting4 ,all his thoughts are bent upon treating them in such a manner that they may allow themselves to be caught4 ,on this account they form one of the main subjects of his religious beliefs and customs4 ,they play a most important part in his mythology1 and a well-nigh endless series of observances regulates their treatment4 ,the mythological explanation of all the prevailing customs in regard to sea-mammals is contained in a tale which describes their origin3 8,a girl named ,avilayuk refused all her suitors1 and for this reason she was also called #8,she who does not want to marry4' ,there was a stone near the village where she lived4 ,it was speckled white and red4 ,the stone transformed itself into a dog and took the girl to wife4 8,she had many children1 some of whom became the ancestors of various fabulous tribes4 ,the children made a great deal of noise1 which annoyed ,avilayuk's father1 so that he finally took them across the water to a small island4 ,every day the dog swam across to the old man's hut to get meat for his family4 ,his wife hung around his neck a pair of boots that were fastened to a string4 ,the old man filled the boots with meat1 and the dog took them back to the island4 8,one day1 while the dog was gone for meat1 a man came to the island in his kayak,c and called the young woman4 #8,take your bag and come with me1' he shouted4 ,he had the appearance of a good-looking1 tall man1 and the woman was well pleased with him4 ,she took her bag1 went down to the kayak1 and the man paddled away with her4 ,after they had gone some distance1 they came to a cake of floating ice4 ,the man stepped out of the kayak on to the ice4 ,then she noticed that he was quite a small man1 and that he appeared large only because he had been sitting on a high seat4 ,then she began to cry1 while he laughed and said1 #8,oh1 you have seen my seat1 have you8' ,according to another version1 he wore snow-goggles made of walrus-ivory1 and he said1 #8,do you see my snow-goggles8' and then laughed at her because she began to cry4 ,then he went back into his kayak1 and they proceeded on their journey4 ,c ,the one-man hunting canoe of the ,eskimo4 8,finally they came to a place where there were many people and many huts4 ,he pointed out to her a certain hut made of the skins of yearling seals1 and told her that it was his1 and that she was to go there4 ,they landed4 ,the woman went up to the hut1 while he attended to his kayak4 ,soon he joined her in the hut1 and staid with her for three or four days before going out sealing again4 ,her new husband was a petrel4 8,meanwhile her father had left the dog1 her former husband1 at his house1 and had gone to look for her on the island4 ,when he did not find her1 he returned home1 and told the dog to wait for him1 as he was going in search of his daughter4 ,he set out in a large boat1 traveled about for a long time1 and visited many a place before he succeeded in finding her4 ,finally he came to the place where she lived4 ,he saw many huts1 and1 without leaving his boat1 he shouted and called his daughter to return home with him4 ,she came down from her hut1 and went aboard her father's boat1 where he hid her among some skins4 8,they had not been gone long when they saw a man in a kayak following them4 ,it was her new husband4 ,soon he overtook them1 and when he came alongside he asked the young woman to show her hand1 as he was very anxious to see at least part of her body1 but she did not move4 ,then he asked her to show her mitten1 but she did not respond to his request4 ,in vain he tried in many ways to induce her to show herself2 she kept in hiding4 ,then he began to cry1 resting his head on his arms1 that were crossed in front of the manhole of the kayak4 ,avilayuk's father paddled on as fast as he could1 and the man fell far behind4 ,it was calm at that time and they continued on their way home4 ,after some time they saw something coming from behind toward their boat4 ,they could not clearly discern it4 ,sometimes it looked like a man in a kayak4 ,sometimes it looked like a petrel4 ,it flew up and down1 then skimmed over the water1 and finally came up to their boat and went round and round it several times and then disappeared again4 ,suddenly ripples came up1 the waters began to rise1 and after a short time a gale was raging4 ,the boat was quite a distance away from shore4 ,the old man became afraid lest they might be drowned2 and1 fearing the revenge of his daughter's husband1 he threw her into the water4 ,she held on to the gunwale2 then the father took his hatchet and chopped off the first joints of her fingers4 ,when they fell into the water they were transformed into whales1 the nails becoming the whalebone4 ,still she clung to the boat2 again he took his hatchet and chopped off the second joints of her fingers4 ,they became transformed into ground seals4 ,still she clung to the boat2 then he chopped off the last joints of her fingers1 which became transformed into seals4 ,now she clung on to the boat with the stumps of her hands1 and her father took his steering-oar and knocked out her left eye4 ,she fell backward into the water and he paddled ashore4 8,then he filled with stones the boots in which the dog was accustomed to carry meat to his family1 and only covered the top with meat4 ,the dog started to swim across1 but when he was halfway the heavy stones dragged him down4 ,he began to sink and was drowned4 ,a great noise was heard while he was drowning4 ,the father took down his tent and went down to the beach at the time of low water4 ,there he lay down and covered himself with the tent4 ,the flood tide rose and covered him1 and when the waters receded he had disappeared40 ,this woman1 the mother of the sea-mammals1 may be considered the principal deity of the ,central ,eskimo4 ,she has supreme sway over the destinies of mankind1 and almost all the observances of these tribes are for the purpose of retaining her good-will or of propitiating her if she has been offended4 ,among the eastern tribes of this region she is called ,sedna1 while the tribes west of ,hudson ,bay call her ,nuliayuk4 ,she is believed to live in a lower world1 in a house built of stone and whale-ribs4 ,in accordance with the myth1 she is said to have but one eye4 ,she cannot walk1 but slides along1 one leg bent under1 the other stretched forward4 ,her father lives with her in this house1 and lies covered up with his tent4 ,the dog watches the entrance1 being stationed on the floor of the house4 ,the souls of seals1 ground seals and whales are believed to proceed from her house4 ,after one of these animals has been killed its soul stays with the body for three days4 ,then it goes back to ,sedna's abode1 to be sent forth again by her4 ,if1 during the three days that the soul stays with the body1 any taboo or prescribed custom is violated1 the violation becomes attached to the animal's soul4 ,although the latter strives to free itself of these attachments1 which give it pain1 it is unable to do so1 and takes them down to ,sedna4 ,the attachments1 in some manner that is not explained1 make her hands sore1 and she punishes the people who are the cause of her pains by sending to them sickness1 bad weather and starvation4 ,the object of the innumerable taboos that are in force after the killing of these sea animals is therefore to keep their souls free from attachments that would hurt their souls as well as ,sedna4 ,the souls of the sea animals are endowed with greater powers than those of ordinary human beings4 ,they can see the effect of the contact with a corpse1 which causes objects touched by it to appear of a dark color2 and they can see the effect of flowing blood1 from which a vapor rises that surrounds the bleeding person and is communicated to every one and every thing that comes in contact with such a person4 ,this vapor and the dark color of death are exceedingly unpleasant to the souls of the sea animals1 that will not come near a hunter thus affected4 ,the hunter must therefore avoid contact with people who have touched a body1 or with such as are bleeding4 ,if any one who has touched a body or who is bleeding should allow others to come in contact with him he would cause them to become distasteful to the seals and therefore also to ,sedna4 ,for this reason the custom demands that every person must at once announce if he has touched a body or if he is bleeding4 ,if he does not do so1 he will bring ill luck to all the hunters4 ,these ideas have given rise to the belief that it is necessary to announce the transgression of any taboo4 ,the transgressor of a custom is distasteful to ,sedna and to the animals1 and those who abide with him will become equally distasteful through contact with him4 ,for this reason it has come to be an act required by custom and morals to confess any and every transgression of a taboo1 in order to protect the community from the evil influences of contact with the evil-doer4 ,the descriptions of ,eskimo life given by many observers contain records of starvation which1 according to the belief of the natives1 was brought about by some one transgressing a law and not announcing what he had done4 ,i presume this importance of the confession of a transgression with a view to warning others to keep at a distance from the transgressor has gradually led to the idea that a transgression1 or we might say a sin1 can be atoned for by confession4 ,this is one of the most remarkable religious beliefs of the ,central ,eskimo4 ,there are innumerable tales of starvation brought about by the transgression of a taboo4 ,in vain the hunters try to supply their families with food2 gales and drifting snow make their endeavors fruitless4 ,finally the help of the angakok,d is invoked1 and he discovers that the cause of the misfortune of the people is due to the transgression of a taboo4 ,then the guilty one is searched for4 ,if he confesses1 all is well1 the weather moderates1 and the seals will allow themselves to be caught2 but if he obstinately maintains his innocence1 his death alone will soothe the wrath of the offended deity4 ,d ,the medicine-man or shaman of the ,eskimo4 ,while thus the reason appears clear why the taboos are rigorously enforced by public opinion1 the origin of the taboos themselves is quite obscure4 ,it is forbidden1 after the death of a sea mammal or after the death of a person1 to scrape the frost from the window1 to shake the beds1 or to disturb the shrubs under the bed1 to remove oil-drippings from under the lamp1 to scrape hair from skins1 to cut snow for the purpose of melting it1 to work on iron1 wood1 stone1 or ivory4 ,women are1 furthermore1 forbidden to comb their hair1 to wash their faces and to dry their boots and stockings4 ,a number of customs1 however1 may be explained by the endeavors of the natives to keep the sea mammals free from contaminating influences4 ,all the clothing of a dead person1 more particularly the tent in which he died1 must be discarded2 for if a hunter should wear clothing made of skins that had been in contact with the deceased1 these would appear dark and the seal would avoid him4 ,neither would a seal allow itself to be taken into a hut darkened by a dead body1 and all those who entered such a hut would appear dark to it and would be avoided4 ,while it is customary for a successful hunter to invite all the men of the village to eat of the seal that he has caught1 they must not take any of the seal meat out of the hut1 because it might come in contact with persons who are under taboo1 and thus the hunter might incur the displeasure of the seal and of ,sedna4 ,it is very remarkable that the walrus is not included in this series of regulations4 ,it is explicitly stated that the walrus1 the white whale and the narwhal are not subject to these laws1 which affect only the sea animals that originated from ,sedna's fingers4 ,there is1 however1 a series of laws that forbid contact between walrus1 seal and caribou4 ,it is not quite clear in what mythical concept these customs originate4 ,there is a tradition regarding the origin of walrus and caribou which is made to account for a dislike between these two animals4 ,a woman created both these animals from parts of her clothing4 ,she gave the walrus antlers and the caribou tusks4 ,when man began to hunt them1 the walrus upset the boats with his antlers and the caribou killed the hunter with his tusks4 ,therefore the woman called both animals back and took the tusks from the caribou and gave them to the walrus4 ,she took the antlers1 kicked the caribou's forehead flat and put the antlers on to it4 ,ever since that time1 it is said1 walrus and caribou avoid each other1 and the people must not bring their meat into contact4 ,they are not allowed to eat caribou and walrus meat on the same day except after changing their clothing4 ,the winter clothing which is made of caribou-skin must be entirely completed before the men will go to hunt walrus4 ,as soon as the first walrus has been killed1 a messenger goes from village to village and announces the news4 ,all work on caribou-skins must cease immediately4 ,when the caribou-hunting season begins1 all the winter clothing1 and the tent that has been in use during the walrus-hunting season1 are buried1 and not used again until the following walrus-hunting season4 ,no walrus hide1 or thongs made of such hide1 must be taken inland1 where is the abode of the caribou4 ,similar laws1 although not quite so stringent1 hold good in regard to contact between seal and walrus4 ,the natives always change their clothing or strip naked before eating seal during the walrus season4 ,the soul of the salmon is considered to be very powerful4 ,salmon must not be cooked in a pot that has been used for boiling other kinds of meat4 ,it is always cooked at some distance from the hut4 ,boots that were used while hunting walrus must not be worn when fishing salmon1 and no work on boot-legs is allowed until the first salmon has been caught and placed on a boot-leg4 ,the fact that these taboos are not restricted to caribou and walrus suggests that the mythical explanation given above does not account for the origin of these customs1 but must be considered as a later effort to explain their existence4 ,the transgressions of taboos do not affect the souls of game alone4 ,it has already been stated that the sea mammals see their effect upon man also1 who appears to them of a dark color1 or surrounded by a vapor which is invisible to ordinary man4 ,this means1 of course1 that the transgression also affects the soul of the evil-doer4 ,it becomes attached to it and makes him sick4 ,the shaman is able to see1 by the help of his guardian spirit1 these attachments1 and is able to free the soul from them4 ,if this is not done the person must die4 ,in many cases the transgressions become attached also to persons who come in contact with the evil-doer4 ,this is especially true of children1 to whose souls the sins of their parents1 and particularly of their mothers1 become readily attached4 ,therefore when a child is sick the shaman1 first of all1 asks its mother if she has transgressed any taboos4 ,the attachment seems to have a different appearance1 according to the taboo that has been violated4 ,a black attachment is due to removing oil-drippings from under the lamp4 ,as soon as the mother acknowledges the transgression of a taboo1 the attachment leaves the child's soul and the child recovers4 ,the souls of the deceased stay with the body for three days4 ,if a taboo is violated during this time the transgression becomes attached to the soul of the deceased4 ,the weight of the transgression causes the soul pain1 and it roams about the village1 endeavoring to free itself of its burden4 ,it seeks to harm the people who1 by their disobedience to custom1 are causing its sufferings4 ,it causes heavy snows to fall and brings sickness and death4 ,such a soul is called a tupilak4 ,toward the middle of autumn it hovers around the doors of the huts4 ,when a shaman discovers the tupilak he advises the people1 who assemble1 and prepare to free it of its burden4 ,all the shamans go in search of it1 each a knife in hand4 ,as soon as they find it1 they stab it with their knives1 and thus cut off the transgressions4 ,then the tupilak becomes a soul again4 ,the knives with which it was stabbed are seen by the people to be covered with blood4 ,the ,central ,eskimo believe that man has two souls4 ,one of these stays with the body1 and may enter temporarily the body of a child which is given the name of the departed4 ,the other soul goes to one of the lands of the souls4 ,of these there are several4 ,there are three heavens1 one above another1 of which the highest is the brightest and best4 ,those who die by violence go to the lowest heaven4 ,those who die by disease go to ,sedna's house first1 where they stay for a year4 ,sedna restores their souls to full health and then she sends them up to the second heaven4 ,those who die by drowning go to the third heaven4 ,people who commit suicide go to a place in which it is always dark and where they go about with their tongues lolling4 ,women who have had premature births go to ,sedna's abode and stay in the lowest world4 ,the other soul stays with the body4 ,when a child has been named after the deceased1 the soul enters its body and remains there for about four months4 ,it is believed that its presence strengthens the child's soul1 which is very light and apt to escape from the body4 ,after leaving the body of the infant1 the soul of the departed stays nearby1 in order to re-enter its body in case of need4 ,when a year has elapsed since the death of the person1 his soul leaves the grave temporarily and goes hunting1 but returns frequently to the grave4 ,when the body has entirely decayed it may remain away for a long time4 ,evidently the ,eskimo also believe in the transmigration of souls4 ,there is one tradition in which it is told how the soul of a woman passed through the bodies of a great many animals1 until finally it was born again as an infant4 ,in another story it is told how a hunter caught a fox in a trap and recognized in it the soul of his departed mother4 ,in still another tale the soul of a woman1 after her death1 entered the body of a huge polar bear in order to avenge wrongs done to her during her lifetime4 ,almost the sole object of the religious ceremonies of the ,eskimo is to appease the wrath of ,sedna1 of the souls of animals1 or of the souls of the dead1 that have been offended by the transgressions of taboos4 ,this is accomplished by the help of the guardian spirits of the angakut4 ,the most important ceremony of the ,eskimo is celebrated in the fall4 ,at this time of the year the angakut1 by the help of their guardian spirits1 visit ,sedna and induce her to visit the village1 and they endeavor to free her of the transgressions that became attached to her during the preceding year4 ,one angakok throws her with his harpoon1 another one stabs her1 and by this means they cut off all the transgressions4 ,the ceremony is performed in a darkened snow-house4 ,after the ceremony the lamps are lighted again and the people see the harpoon and the knife that were used in the ceremony covered with blood4 ,if the angakut should fail to free ,sedna from the transgressions1 bad weather and hunger would prevail during the ensuing winter4 ,on the following day ,sedna sends her servant1 who is called ,kaileteta1 to visit the tribe4 ,she is represented by a man dressed in a woman's costume and wearing a mask made of seal-skin4 ,on this day the people wear attached to their hoods pieces of skin of that animal of which their first clothing was made after they were born4 ,it seems that the skins of certain animals are used for this purpose1 each month having one animal of its own4 ,it is said that if they should not wear the skin of the proper animal1 ,sedna would be offended and would punish them4 ,the angakut also cure sick persons and make good weather with the help of their guardian spirits4 ,they discover transgressions of taboos and other causes of ill luck4 ,one of the most curious methods of divination applied by the angakut is that of #8head-lifting4' ,a thong is placed around the head of a person who lies down next to the patient4 ,the thong is attached to the end of a stick which is held in hand by the angakok4 ,then the latter asks questions as to the nature and outcome of the disease1 which are supposed to be answered by the soul of a dead person1 which makes it impossible for the head to be lifted if the answer is affirmative1 while the head is raised easily if the answer is negative4 ,as soon as the soul of the departed leaves1 the head can be moved without difficulty4 ,amulets are extensively used as a protection against evil influences and to secure good luck4 ,pregnant women wear the teeth of wolves on the backs of their shirts4 ,these same teeth are fastened to the edge of the infant's hood4 ,the string which passes under the large hood of the woman who carries her child on her back is fastened at one end to a bear's tooth1 which serves to strengthen the child's soul4 ,when the child begins to walk about1 this string and the bear's tooth are attached to its shirt and worn as amulets4 ,pyrites1 when thrown upon a spirit1 are believed to drive it away4 ,as compared with the beliefs of the ,greenlanders1 the beliefs of the ,central ,eskimo are characterized by the great importance of the ,sedna myth and the entire absence of the belief in a powerful spirit called ,tonarssuk1 which seems to have been one of the principal features of ,greenland beliefs4 ,there is an evident tendency among the ,central ,eskimo to affiliate all customs and beliefs with the myth of the origin of sea animals4 ,this tendency seems to have been one of the principal causes that molded the customs and beliefs of the people into the form in which they appear at the present time4 ,,mental ,,energy4,e ,,by ,,edward ,,atkinson4 ,e ,presented before the ,new ,york meeting of the ,american ,association for the ,advancement of ,science4 ,according to the common conception1 political economy is held to deal with material forces only2 with land1 labor and capital2 with the production1 distribution and consumption of the materials of human existence4 ,these are food1 clothing and shelter4 ,it1 therefore1 bears the aspect of a purely material study of material forces4 ,yet no more purely metaphysical science exists1 and there can be1 in my view of the subject1 no more ideal conceptions than those which are derived from the study of these purely material forces4 ,many of the errors commonly presented under the name of the #8claims of labor' have arisen from the limited and partial conception of the function of economic science4 ,we have become accustomed to deal with the so-called material forces of nature and with the physical work and labor of man under the general term of #8,energy'4 ,what man does by his own labor or physical energy is to convert the products of land and sea1 of mine and forest1 into new forms from which he derives shelter1 food and clothing4 ,in a material sense all that any one can get in or out of life1 be he rich or poor1 is what we call our board and clothing4 ,such being the fact1 what a man consumes is his cost to the community2 what he spends yields to others the means of buying the supplies for their own wants2 their consumption is then their cost to the community4 ,the physical forces of nature are limited4 ,the earth is endowed with a fixed quantity of materials that we call gaseous1 liquid and solid4 ,it receives a certain amount of heat from the sun which1 for all practical purposes1 may be considered a fixed quantity of energy1 even if in eons it may be exhausted4 ,the physical energy of man is devoted to the transformation of these physical forces under the law of conservation2 he can neither add to nor diminish the quantity4 ,he can transform solid into gas and gas into liquid4 ,he can1 according to common speech1 consume some of these products1 but his consumption is only another transformation4 ,his own body is but one of the forms of physical energy on the way toward another form4 ,these elements of nature1 formerly limited to earth1 air and water1 are now listed under many titles of what are called elements2 ,i believe over sixty that have not yet been differentiated1 but all may yet be resolved into a unit of force4 ,you will observe that in our arithmetic we have ten numerals which can be divided into fractions4 ,in our music we deal with seven notes and their variants4 ,in our alphabet we have twenty-six letters4 ,these factors correspond in some measure to what we call elements in nature4 ,there is a limit to the number of combinations that can be made of the numerals and their fractions1 to the notes of music and their variants1 and of the letters of the alphabet2 but in each case this limit is so remote as to be negligible1 like the exhaustion of the heat of the sun4 ,may we not deal with the elements of nature in the same way8 ,can any one prescribe a limit to their conversion and reconversion to the use of mankind8 ,is it not in these processes of conversion that we derive our subsistence8 ,we make nothing4 ,all that we can do is to move something4 ,we move the soil and we move the seed2 nature gives the harvest4 ,we direct the currents of falling water1 of heat and of steam2 nature imparts the force or energy to which man has only given a new direction4 ,we are now imparting new directions to the force that we call electricity1 and to what we call cold4 ,what is the force from which we derive this power of transforming physical energy8 ,may we not call it mental energy8 ,is not mental energy the factor in mankind by which he is differentiated from the beast8 ,does not man only accumulate experience1 and is there any limit to the power of mind over matter8 ,if these points are well taken1 mental energy is the fourth and paramount factor in providing for material existence1 and the science of political economy1 which deals with land1 labor and capital1 becomes a purely metaphysical science when we admit the force of mental energy into the combination4 ,we deal1 as ,i have said1 with sixty elements1 so-called1 more or less1 but the unity of nature is the most important fact ever proved by science2 the correlation of all forms of physical energy leading logically from the idea of manifold forces or gods to the unity of creation1 necessarily ending in the conception of unity of a creator1 or the one ,god4 ,this modern development of mental science is but the ,hebrew concept of the creation in a new form4 ,the ,hebrew race was the first one of the historic races with whom the unity of creation and the unity of the creator became an article of faith4 ,i doubt not that it was in that concept and the power derived from it that the ,hebrew intellect asserted its preminence in the history of the world4 ,according to that concept1 to man is given 8dominion over the fish of the sea and over the fowl of the air and over every living thing that moveth upon the earth40 ,by what force does man hold dominion unless it is through his mental energy and his capacity to accumulate experience8 ,all the industrial arts are antedated by the industries of animals4 ,the tailor finds his prototype in the tailor bird2 the mason in the wasp2 the farmer in the agricultural ant2 the bridge-builder in the spider2 the weaver in the weaver bird2 the creator of water power in the beaver1 and so on4 ,yet no other animal except man has developed or extended any of these arts4 ,no other animal except man has learned to make and use fire and not to run away from it4 ,if1 then1 man by his power of mental energy converts the original and crude forces with which the earth is endowed into new forms1 and by giving them new direction increases his power of production of the means of his own subsistence and enjoyment of life1 does it not follow that creation is a continuous procession in which man is a factor8 8,there is a divinity that shapes our ends1 rough hew them as we may40 ,the ideal of #8an honest ,god the noblest concept of man' becomes the converse of an honest man the noblest work of ,god--honest in a broad sense in his dealings with the forces of nature2 true to his function4 ,there is a painful side to statistical and economic study4 ,the penalty of being able to read what is written between the lines and the columns of the figures is the conclusion that after we have all done the best work that the present conditions of science will permit1 the entire product barely suffices to keep mankind in existence2 his fixed capital1 so-called1 is at the mercy both of time and of the inventor who substitutes better methods which at less cost of effort or labor yield more abundance to the community as a whole4 ,but on the other hand1 no matter how hard the struggle for existence may be1 we find the promise of future abundance even in the insufficient product which has been derived from the application of science and invention up to date4 ,witness the relative progress of the last century as compared with all the previous centuries2 then attempt to conceive what will be the condition of humanity a century hence1 knowing1 as we do1 that the applications of science through mental energy now proceed in geometric progression1 reversing the dogma of ,malthus and leading to the concept of production unlimited1 consumption limited4 ,if it be true that there is no conceivable limit to the power of mind over matter or to the number of conversions of force that can be developed1 providing in increasing measure for the wants of the human body1 it follows that pauperism is due to poverty of mental energy1 not of material resources4 ,the next step in the development of this theory may be presented in this form3 ,no man is paid by the measure in time or physical effort1 for the work or labor that he performs4 ,no man can claim payment in money or in kind on the ground that he has done a day's work of a greater or less number of hours4 ,in all civilized countries we are members one of another2 rich or poor2 whether we work with our hands or our heads1 or both combined4 ,material existence is supported by conversion of one form of physical energy into another4 ,social energy is maintained by the exchange of one form of service for another4 ,the measure of compensation is not the number of hours of labor put into the product or service4 ,the standard by which services are measured is what the buyer is saved from doing1 not what the seller does4 ,each of us might possibly be able to house1 clothe and feed ourselves if we were cast upon an island possessing sufficient natural resources4 ,if a hundred persons representing all the classes in society were wrecked upon such an island1 each adult or each person above ten years old would probably find a way to house1 feed and clothe himself4 ,why do we not house1 feed and clothe ourselves1 and why would not the hundred representatives of different classes wrecked on an island each do his own part of the work for himself only8 ,simply for the reason that men are either endowed from birth with different aptitudes1 or different aptitudes are developed in their environment4 ,each one finds out that by delegating to another certain kinds of work he saves his own time and energy4 ,each one finds out what he can do for the next man1 while the next man finds out what he can do for him4 ,there is in every transaction of life an unconscious cerebration or estimate of the services rendered to us1 saving each of us mental or manual energy1 whenever we buy any product or service from another4 ,that unconscious cerebration affects the minds or habits or acts of both parties in every purchase and sale4 ,there may be errors in regard to the service itself4 ,the ignorant man will buy quack medicines that he had better let alone1 but what he pays under the false impression of benefit to himself is his measure of what he hopes to save2 while the quack medicine vender1 taking advantage of the ignorance of others1 filches from them the means of subsistence1 even of wealth1 under the pretext of service4 ,as time goes on1 however1 false measures of service are eliminated with increasing intelligence1 and true benefits constitute more and more the vast proportion of the exchanges4 ,the same ignorance which leads the masses of the people of every country to submit to military dictation1 even in a bad cause1 also leads to the wars of tariffs among nations by which prejudice and animosity are kept up4 ,the false conception that in international commerce what one nation gains another must lose1 is promoted by the advocates of protection1 many of whom very honestly believe that through the exclusion of foreign goods domestic industry may be promoted1 wholly ignoring the fact that arts and industries are developed by intelligence and not by legislation4 ,the advocates of bounties and of special legislation also ignore the fact that in this country1 where mental energy is more nearly free in its action than in any other1 manufactures and the mechanic arts develop in due proportion according to the age and the natural resources of the territory or state1 nine-tenths or more of the occupations which are listed under these titles being free in the nature of things from any possibility of foreign competition through the import of a product of like kind4 ,there may be nothing new in this essay1 but until my own observation had led me to the conclusion that land1 labor and capital were alike inert and incapable without the cordinating power of mental energy1 the doubt continued to exist in my mind which is often expressed about the possibility of economic science having any real existence or right to the title4 ,also1 until my own observation led me to the conclusion that the cost of a man to the community is what he consumes1 and not what he secures in the way of income1 the correlation of wealth and welfare had not been satisfactorily reconciled4 ,i think that a very large part of what is written under the title of political economy would be greatly modified1 and perhaps never have been written1 had these concepts been derived by the writers from experience1 as they have been in my own observation4 ,i have not much patience with abstract or priori theories1 my own method being one of observation1 then referring to the various authorities in order to find out whether my observations or their abstract theories have been shallow and superficial4 ,again1 ,i find in the ideal of the continuous miracle of creation in which man is a factor the solution of many intellectual difficulties4 ,in the face of such a perception of the methods of the universe1 the larger part of the dogmas that have been put forth under the name of religion take their place with much of the historic rubbish which passes under the name of history4 ,when it becomes plain that every man has his place in the progress of continuous creation1 and is a factor in it2 that nothing is constant but change2 that there is no such thing as fixed capital2 all the doubts and fears regarding the future of humanity vanish in the light of sure progress4 ,what greater stimulus can there be than for every man each in his own way rendering service for service1 his objective point being only the welfare of himself and his family1 when he attains the conviction that by so much as his mental energy adds to the sum of the utilities by which mankind lives1 so may that part which he consumes and which represents his cost to the community be fully justified1 even though it is earned with more apparent ease and less physical exertion than are called for from his poorer neighbors4 ,incomplete as his studies were1 ,i have always found in the #8,harmonies' of ,frederic ,bastiat the greatest encouragement and the greatest incentive to the work which ,i have undertaken under the name of political economy1 leading more and more to the conviction that war and warfare1 whatever influence they may have had in developing progress in the past1 are now due to ignorance and greed2 the war of tariffs due to selfishness and stupidity2 and the contest of labor and capital due to the errors of the ignorant workman and the ignorant capitalist alike4 ,all interests are harmonious4 ,the evolution of science and invention will surely bring them together on the lines of righteousness1 peace and material abundance4 ,this essay has been condensed from a lecture prepared and given before a ,clergymen's ,club some months ago4 ,in it ,i tried to show the necessary connection of religion and life as developed by economic study1 the law of mutual service being the rule by which commerce lives and moves and has its being4 ,this lecture has since been read to several clubs of very different types of men1 and from the great interest excited ,i am led to think there is something in it fit for the student of facts and figures to say4 ,i may1 therefore1 venture to repeat the statement of two principles which are presented in this treatise1 which ,i think have been seldom if ever fully developed in any of the standard works upon political economy4 ,to my own mind these are basic principles which when applied may profoundly modify many of the concepts of students of economic science4 ,i join in the view that the family is the unit of society1 the home the center4 ,the end of all production is consumption4 ,nothing is constant but change1 and there is no such thing as fixed material capital of any long duration in the progress of time4 ,the two principles which ,i have endeavored to enforce are as follows3 ,first4 ,the cost of each person or head of the family is what he and his immediate dependents consume4 ,his income1 whether measured in terms of money or in products1 is1 therefore1 no measure of his cost2 what he distributes in payment for service rendered being expended by those who receive it in procuring the commodities which constitute their cost to the community4 ,second4 ,no person who is occupied or is in the employment or service of others is paid for what he does4 ,his work may occupy long hours and may be applied to arduous manual labor1 or it may be done in a short number of hours per day1 with but little physical effort4 ,neither the hours nor the effort constitute any measure on which payment can be based4 ,the measure of payment is fixed by the measure of the work saved to him who makes the payment1 consciously or unconsciously estimated4 ,these two precepts or principles1 coupled with the theory that there is no conceivable limit to the power of mind over matter1 or to the number of transformations of physical energy to which direction may be given in the material support of humanity1 bring the visions of the ,utopians within the scope of a law of progress in material welfare to which no limit can be put in time or space4 ,,chapters ,,on ,,the ,,stars4 ,,by ,,prof4 ,,simon ,,newcomb1 ,u4 ,s4 ,n4 ,,variable ,,stars4 ,it is a curious fact that the ancient astronomers1 notwithstanding the care with which they observed the heavens1 never noticed that any of the stars changed in brightness4 ,the earliest record of such an observation dates from #aeif1 when the periodical disappearance of ,omicron ,ceti was noticed4 ,after this1 nearly two centuries elapsed before another case of variability in a star was recorded4 ,during the first half of the nineteenth century ,argelander so systematized the study of variable stars as to make it a new branch of astronomy4 ,in recent years it has become of capital interest and importance through the application of the spectroscope4 ,students who are interested in the subject will find the most complete information attainable in the catalogues of variable stars1 published from time to time by ,chandler in the #8,astronomical ,journal4' ,his third catalogue1 which appeared in #ahif1 comprises more than #cjj stars whose variability has been well established1 while there is always a long list of #8suspected variables'--whose cases are still to be tried4 ,the number to be included in the established list is continually increasing at such a rate that it is impossible to state it with any approximation to exactness4 ,the possibility of such a statement has been yet further curtailed by the recent discovery at the ,harvard ,observatory that certain clusters of stars contain an extraordinary proportion of variables4 ,altogether at the time of the latest publication1 #eji such stars were found in twenty-three clusters4 ,the total number of these objects in clusters1 therefore1 exceeds the number known in the rest of the sky4 ,they will be described more fully in a subsequent chapter4 ,for the present we are obliged to leave this rich field out of consideration and confine our study to the isolated variable stars which are found in every region of the heavens4 ,variable stars are of several classes1 which1 however1 run into each other by gradations so slight that a sharp separation cannot always be made between them4 ,yet there are distinguishing features1 each of which marks so considerable a number of these stars as to show some radical difference in the causes on which the variations depend4 ,we have first to distinguish the two great classes of irregular and periodic stars4 ,the irregular ones increase and diminish in so fitful a way that no law of their change can be laid down4 ,to this class belong the so-called #8new stars'1 which1 at various periods in history1 have blazed out in the heavens1 and then in a few weeks or months have again faded away4 ,it is a remarkable fact that no star of the latter class has ever been known to blaze out more than once4 ,this fact distinguishes new stars from other irregularly variable ones4 ,periodic stars are those which go through a regular cycle of changes in a definite interval of time1 so that1 after a certain number of days1 sometimes of hours1 the star returns to the same brightness4 ,but even in the case of periodic stars1 it is found that the period is more or less variable1 and1 in special cases1 the amount of the variation is such that it cannot always be said whether we should call a star periodic or irregular4 ,the periodic stars show wide differences1 both in the length of the period and in the character of the changes they undergo4 ,in most cases they rapidly increase in brightness during a few days or weeks1 and then slowly fade away1 to go through the same changes again at the end of the period4 ,in other cases they blaze up or fade out1 from time to time1 like the revolving light of a lighthouse4 ,some stars are distinguished more especially by their maximum1 or period of greatest brightness1 while others are more sharply marked by minima1 or periods of least brightness4 ,in some cases there are two unequal minima in the course of a period4 ,chandler's third catalogue of variable stars gives the periods of #bhj of these objects1 which seem to have been fairly well made out4 ,a classification of these periods1 as to their length1 will be interesting4 ,there are1 of periods3 ,less than #ej days #fc ,stars4 ,between #ej and #ajj days #f 0 0 #ajj 0 #aej 0 #i 0 0 #aej 0 #bjj 0 #ah 0 0 #bjj 0 #bej 0 #bi 0 0 #bej 0 #cjj 0 #dj 0 0 #cjj 0 #cej 0 #dd 0 0 #cej 0 #djj 0 #dd 0 0 #djj 0 #dej 0 #ah 0 0 #dej 0 #ejj 0 #f 0 0 #ejj 0 #eej 0 #a 0 0 #eej 0 #fjj 0 #a 0 0 #fjj 0 #fej 0 #a 0 ,it will be seen from this that1 leaving out the cases of very short period1 the greater number of the periods fall between #cjj and #djj days4 ,from this value the number falls off in both directions4 ,only three periods exceed #ejj days1 and of these the longest is #faj days4 ,we infer from this that there is something in the constitution of these stars1 or in the causes on which their variation depends1 which limits the period4 ,this limitation establishes a well-marked distinction between the periodic stars and the irregular variables to be hereafter described4 ,returning to the upper end of the scale1 the contrast between the great number of stars less than fifty days1 and the small number between fifty and one hundred1 seems to show that we have here a sharp line of distinction between stars of long and those of short period4 ,but1 when we examine the matter in detail1 the statistics of the periods do not enable us to draw any such line4 ,about eight periods are less than one day1 and the number of this class known to us is continually increasing4 ,about forty are between one and ten days1 and from this point upwards they are scattered with a fair approach to equality up to a period of one hundred days4 ,there is1 however1 a possible distinction1 which we shall develop presently4 ,illustration3 ,,fig4 #a4 ,,the ,,law ,,of ,,change ,,in ,a ,,variable ,,star4 ,the law of change in a variable star is represented to the eye by a curve in the following way4 ,we draw a straight horizontal line ,a ,x to represent the time4 ,a series of equidistant points1 a1 b1 c1 d1 etc41 on this will represent moments of time4 ,one of the spaces1 a1 b1 c1 etc41 may represent an hour1 a day1 or a month1 according to the rapidity of change4 ,we take a to represent the initial moment1 and erect an ordinate aa'1 of such length as to represent the brightness of the star on some convenient scale at this moment4 ,at the second moment1 b1 which may be an hour or a day later1 we erect another ordinate bb'1 representing the brightness at this moment4 ,we continue this process as long as may be required4 ,then we draw a curve1 represented by the dotted line1 through the ends of all the ordinates4 ,in the case of a periodic star it is only necessary to draw the curve through a single period1 since its continuation will be a repetition of its form for any one period4 ,we readily see that if a star does not vary1 all the ordinates will be of equal length1 and the curve will be a horizontal straight line4 ,moreover1 the curve will take this form through any portion of time during which the light of the star is constant4 ,there are three of the periodic stars plainly visible to the naked eye at maximum1 of which the variations are so wide that they may easily be noticed by any one who looks for them at the right times1 and knows how to find the stars4 ,these stars are3 ,omicron ,ceti1 called also ,mira ,ceti4 ,beta ,persei1 or ,algol4 ,beta ,lyr4 ,it happens that each of these stars exemplifies a certain type or law of variations4 ,omicron ,ceti4 ,on ,august #ac1 #aeif1 ,david ,fabricius noticed a star in the constellation ,cetus1 which was not found in any catalogue4 ,bayer1 in his #8,uranometria'1 of which the first edition was published in #afja1 marked the star ,omicron1 but said nothing about the fact that it was visible only at certain times4 ,fabricius observed the star from time to time1 until #afji1 but he does not appear to have fully and accurately recognized its periodicity4 ,but so extraordinary an object could not fail to command the attention of astronomers1 and the fact was soon established that the star appeared at intervals of about eleven months1 gradually fading out of sight after a few weeks of visibility4 ,observations of more or less accuracy having been made for more than two centuries1 the following facts respecting it have been brought to light3 ,its variations are somewhat irregular4 ,sometimes1 when at its brightest1 it rises nearly or quite to the second magnitude4 ,this was the case in ,october1 #ahih1 when it was about as bright as ,alpha ,ceti4 ,at other times its maximum brightness scarcely exceeds the fifth magnitude4 ,no law has yet been discovered by which it can be predicted whether it shall attain one degree of brightness or another at maximum4 ,its minima are also variable4 ,sometimes it sinks only to the eighth magnitude2 at other times to the ninth or lower4 ,in either case it is invisible to the naked eye4 ,as with other stars of this kind1 it brightens up more rapidly than it fades away4 ,it takes a few weeks from the time it becomes visible to reach its greatest brightness1 whatever that may be4 ,it generally retains this brightness for two or three weeks1 then fades away1 gradually at first1 afterward more rapidly4 ,the whole time of visibility will1 therefore1 be two or three months4 ,of course1 it can be seen with a telescope at any time4 ,the period also is variable in a somewhat irregular way4 ,if we calculate when the star ought to be at its greatest brightness on the supposition that the intervals between the maxima ought to be equal1 we shall find that sometimes the maximum will be thirty or forty days early1 and at other times thirty or forty days late4 ,these early or late maxima follow each other year after year1 with a certain amount of regularity as regards the progression1 though no definable law can be laid down to govern them4 ,thus1 during the period from #aghb to #ahjj it was from thirteen to twenty-four days late4 ,in #ahab it was thirty-nine days late4 ,from #ahde to #ahef it was on the average about a month too early4 ,several recent maxima1 notably those from #ahie to #ahih1 again occurred late4 ,formul have been constructed to show these changes1 but there is no certainty that they express the actual law of the case4 ,indeed1 the probability seems to be that there is no invariable law that we can discover to govern it4 ,argelander fixed the length of the period at #cca4i days4 ,more recently1 ,chandler fixed it at #cca4f days4 ,it would seem1 therefore1 to have been somewhat shorter in recent times4 ,it was at its maximum toward the end of ,october1 #ahih4 ,we may1 therefore1 expect that future maxima will occur in ,july1 #aija2 ,june1 #aijb2 ,may1 #aijc2 ,april1 #aijd1 and so on1 about a month earlier each year4 ,during the few years following #aijc the maxima will probably not be visible1 owing to the star being near conjunction with the sun at the times of their occurrence4 ,the most plausible view seems to be that changes of a periodic character1 involving the eruption of heated matter from the interior1 of the body to its surface1 followed by the cooling of this matter by radiation1 are going on in the star4 ,the star ,algol1 or ,beta ,persei1 as it is commonly called in astronomical language1 may1 in northern latitudes1 be seen on almost any night of the year4 ,in the early summer we should probably see it only after midnight1 in the northeast4 ,in late winter it would be seen in the northwest4 ,from ,august until ,january one can find it at some time in the evening by becoming acquainted with the constellations4 ,it is nearly of the second magnitude4 ,one might look at it a score of times without seeing that it varied in brilliancy4 ,but at certain stated intervals1 somewhat less than three days1 it fades away to nearly the fourth magnitude for a few hours1 and then slowly recovers its light4 ,this fact was first discovered by ,goodrick in #aghc1 since which time the variations have been carefully followed4 ,the law of variation thus defined is expressed by a curve of the following form3 ,illustration3 ,,fig4 #b4 ,,law ,,of ,,variation ,,of ,a ,,star ,,of ,,the ,,algol ,,type4 ,the idea that what we see in the star is a partial eclipse caused by a dark body revolving round it1 was naturally suggested even to the earliest observers4 ,but it was impossible to test this theory until recent times4 ,careful observation showed changes in the period between the eclipses1 which1 although not conclusive against the theory1 might have seemed to make it somewhat unlikely4 ,the application of the spectroscope to the determination of radial motions1 enabled ,vogel1 of ,potsdam1 in #ahhi1 to set the question at rest4 ,his method of reasoning and proceeding was this3 ,if the fading out which we see is really due to an eclipse by a dark body1 that body must be nearly or quite as large as the star itself1 else it could not cut off so much of its light4 ,in this case1 it is probably nearly as massive as the star itself1 and therefore would affect the motion of the star4 ,both bodies would1 in fact1 revolve around their common center of gravity4 ,therefore1 when after the dark body has passed in front of the star1 it has made one-fourth of a revolution1 which would require about seventeen hours1 the star would be moving towards us4 ,again1 seventeen hours before the eclipse1 it ought to be moving away from us4 ,the measurement of six photographs of the spectrum1 of which four were taken before the eclipses and two afterward1 gives the following results3 ,before eclipses3 ,velocity from the sun equals #ci km4 per second4 ,after eclipses3 ,velocity toward the sun equals #dg km4 per second4 ,these results show that the hypothesis in question is a true one1 and afforded the first conclusive evidence of a dark body revolving around a distant star4 ,a study of the law of diminution and recovery of the light during the eclipse1 combined with the preceding motions1 enabled ,vogel to make an approximate estimate of the size of the orbit and of the two bodies4 ,the star itself is somewhat more than a million of miles in diameter2 the dark companion a little less4 ,the latter is about the size of our sun4 ,their distance apart is somewhat more than three millions of miles2 the respective masses are about one-half and one-fourth that of the sun4 ,these results1 though numerically rather uncertain1 are probably near enough to the truth to show us what an interesting system we here have to deal with4 ,we can say with entire certainty that the size and mass of the dark body exceed those of any planet of our system1 even ,jupiter1 several hundred fold4 ,the period of the star is also subject to variations of a somewhat singular character4 ,these have been attributed by ,chandler to a motion of the whole system around a third body1 itself invisible4 ,this theory is1 however1 still to be proved4 ,quite likely the planet which causes the eclipse is not the only one which revolves around this star4 ,the latter may be the center of a system like our solar system1 and the other planets may1 by their action1 cause changes in the motion of the body that produces the eclipses4 ,the most singular feature of the change is that it seems to have taken place quite rapidly1 about #ahdj4 ,the motion was nearly uniform up to near this date2 then it changed1 and again remained nearly uniform until #ahij4 ,since then no available observations have been published4 ,it is found that several other stars vary in the same way as ,algol2 that is to say1 they are invariable in brightness during the greater part of the time1 but fade away for a few days at regular intervals4 ,this is a kind of variation which it is most difficult to discover1 because it will be overlooked unless the observer happens to notice the star during the time when an eclipse is in progress1 and is thoroughly aware of its previous brightness4 ,one might observe a star of this kind very accurately a score of times1 without hitting upon a moment when the partial eclipse was in progress4 ,on the principle that like effects are due to like causes1 we are justified in concluding that in the cases of all stars of this type1 the eclipses are caused by the revolution of a dark body1 now called #8,algol variables1' round the principal star4 ,a feature of all the ,algol variables is the shortness of the periods4 ,the longest period is less than five days1 while three are less than one day4 ,this is a result that we might expect from the nature of the case4 ,the nearer a dark planet is to the star1 the more likely it will be to hide its light from an observer at a great distance4 ,if1 for example1 the planet ,jupiter were nearly as large as the sun1 the chances would be hundreds to one against the plane of the orbit being so nearly in the line of a distant observer that the latter would ever see an eclipse of the sun by the planet4 ,but if the planet were close to the sun1 the chances might increase to one in ten1 and yet farther to almost any extent1 according to the nearness of the two bodies4 ,still1 we cannot set any definite limit to the period of stars of this type2 all we can say is that1 as the period we seek for increases1 the number of stars varying in that period must diminish4 ,this follows not only from the reason just given1 but from the fact that the longer the interval that separates the partial eclipses of a star of the ,algol type1 the less likely they are to be detected4 ,,stars ,,of ,,the ,,beta ,,lyr ,,type4 ,the star ,beta ,lyr shows variations quite different in their nature from those of ,algol1 yet having a certain analogy to them4 ,anyone who looks at the constellation ,lyr a few nights in succession and compares ,beta with ,gamma1 a star of nearly the same brightness in its neighborhood1 will see that while on some evenings the stars are of equal brightness1 on others ,beta will be fainter by perhaps an entire magnitude4 ,a careful examination of these variations shows us a very remarkable feature4 ,on a preliminary study1 the period will seem to be six and one-half days4 ,but1 comparing the alternate minima1 we shall find them unequal4 ,hence the actual period is thirteen days4 ,in this period there are two unequal minima1 separated by equal maxima4 ,that is to say1 the partial eclipses at intervals of six and one-half days are not equal4 ,at the alternate minima the star is half as bright again as at the intermediate minima4 ,it is impossible to explain such a change as this merely by the interposition of a dark body1 and this for two reasons4 ,instead of remaining invariable between the minima1 the variation is continuous during the whole period1 like the rising and falling of a tide4 ,moreever1 the inequality of the alternating minima is against the theory4 ,pickering1 however1 found from the doubling of the spectral lines that there were two stars revolving round each other4 ,then ,prof4 ,g4 ,w4 ,myers1 of ,indiana1 worked out a very elaborate mathematical theory to explain the variations1 which is not less remarkable for its ingenuity than for the curious nature of the system it brings to light4 ,his conclusions are these3 ,beta ,lyr consists of two bodies1 gaseous in their nature1 which revolve round each other1 so near as to be almost touching4 ,they are of unequal size4 ,both are self-luminous4 ,by their mutual attraction they are drawn out into ellipsoids4 ,the smaller body is somewhat darker than the other4 ,when we see the two bodies laterally1 they are at their brightest4 ,as they revolve1 however1 we see them more and more end on1 and thus the light diminishes4 ,at a certain point one begins to cover the other and hide its light4 ,thus the combined light continues to diminish until the two bodies move across our line of sight4 ,then we have a minimum4 ,at one minimum1 however1 the smaller and darker of the two bodies is projected upon the brighter one1 and thus diminishes its light4 ,at the other minimum1 it is hiding behind the other1 and therefore we see the light of the larger one alone4 ,this theory receives additional confirmation from the fact1 shown by the spectroscope1 that these stars are either wholly gaseous1 or at least have self-luminous atmospheres4 ,some of ,professor ,myers's conclusions respecting the magnitudes are summarized as follows3 ,the larger body is about #j4d as bright as the smaller4 ,the flattening of the ellipsoidal masses is about #j4ag4 ,the distance of centers is about #a-g_/h the semi-major axis of the larger star1 or about #ej1jjj1jjj kilometers 7say #cj1jjj1jjj miles74 ,the mass of the larger body is about twice that of the smaller1 and #i times the mass of the sun4 ,the mean density of the system is a little less than that of air4,f ,f #8,astrophysical ,journal'1 ,vol4 ,,vii1 ,january1 #ahih4 ,it should be remarked that these numbers rest on spectroscopic results1 which need further confirmation4 ,they are1 therefore1 liable to be changed by subsequent investigation4 ,what is most remarkable is that we have here to deal with a case to which we have no analogy in our solar system1 and which we should never have suspected1 had it not been for observations of this star4 ,the gap between the variable stars of the ,algol type and those of the ,beta ,lyr type is1 at the present time1 being filled by new discoveries in such a way as to make a sharp distinction of the two classes difficult4 ,it is characteristic of the ,algol type proper that the partial eclipses are due to the interposition of a dark planet revolving round the bright star4 ,but suppose that we have two nearly equal stars1 ,a and ,b1 revolving round their common center of gravity in a plane passing near our system4 ,then1 ,a will eclipse ,b1 and1 half a revolution later1 ,b will eclipse ,a1 and so on in alternation4 ,but1 when the stars are equal1 we may have no way of deciding which is being eclipsed1 and thus we shall have a star of the ,algol type1 so far as the law of variation is concerned1 yet1 as a matter of fact1 belonging rather to the ,beta ,lyr type4 ,if the velocity in the line of sight could be measured1 the question would be settled at once4 ,but only the brightest stars can1 so far1 be thus measured1 so that the spectroscope cannot help us in the majority of cases4 ,the most interesting case of this kind yet brought to light is that of ,tau ,cygni4 ,the variability of this star1 ordinarily of the fourth magnitude1 was discovered by ,chandler in ,december1 #ahhf4 ,the minima occurred at intervals of three days4 ,but in the following summer he found an apparent period of #a d4 #ab h41 the alternate minima being invisible because they occurred during daylight1 or when the star was below the horizon4 ,with this period the times of minima during the summer of #ahhh were predicted4 ,it was then found that the times of the alternate minima1 which1 as we have just said1 were the only ones visible during any one season1 did not correspond to the prediction4 ,the period seemed to have greatly changed4 ,afterward1 it seemed to return to its old value4 ,after puzzling changes of this sort1 the tangle was at length unraveled by ,dunr1 of ,lund1 who showed that the alternate periods were unequal4 ,the intervals between minima were one day nine hours1 one day fifteen hours1 one day nine hours1 one day fifteen hours1 and so on1 indefinitely4 ,this law once established1 the cause of the anomaly became evident4 ,two bright stars revolve round their common center of gravity in a period of nearly three days4 ,each eclipses the other in alternation4 ,the orbit is eccentric1 and1 in consequence1 one-half of it is described in a less time than the other half4 ,if we could distinguish the two stars by telescopic vision1 and note their relative positions at the four cardinal points of their orbit1 we should see the pair alternately single and double1 as shown in the following diagrams3 ,a ,b ,position 7#a71 stars at pericenter 99 99 ,interval1 #af hours4 ,position 7#b71 ,a eclipses ,b 99 ,interval1 #bj hours4 ,b ,a ,position 7#c71 stars at apocenter 99 99 ,interval1 #bj hours4 ,position 7#d71 ,b eclipses 99 ,interval1 #af hours4 ,position 7#a7 is repeated 99 99 ,u ,pegasi is a star which proved as perplexing as ,tau ,cygni4 ,it was first supposed to be of the ,algol type1 with a period of about two days4 ,then it was found that a number of minima occurred during this period1 and that the actual interval between them was only a few hours4 ,the great difficulty in the case arises from the minuteness of the variation1 which is but little more than half a magnitude between the extremes4 ,the observations of ,wendell1 at the ,harvard ,observatory1 with the polarizing photometer1 enabled ,pickering to reach a conclusion which1 though it may still be open to some doubt1 seems to be the most likely yet attainable4 ,the star is of the ,beta ,lyr type2 its complete period is #h hours #ei minutes #da seconds1 or #ai seconds less than nine hours2 during this period it passes through two equal maxima1 each of magnitude #i4c1 and two unequal minima #i4gf and #i4i1 alternately4 ,illustration3 ,,fig4 #c4 ,,light ,,curve ,,of ,u ,,pegasi1 ,,of ,,the ,,beta ,,lyr ,,type1 ,,from ,,observations ,,by ,,wendell ,,at ,,the ,,harvard ,,observatory4 ,,magnitude ,,at ,,maximum1 #i4cb2 ,,at ,,principal ,,minimum1 #i4ij2 ,,at ,,secondary ,,minimum1 #i4gf4 ,,period1 #i ,,hours4 ,the difference of these minima1 #jm4 #ad1 is less than the errors which really ordinarily affect measures of a star's magnitude with the best photometers4 ,some skepticism has1 therefore1 been felt as to the reality of the difference which1 if it does not exist1 would reduce the periodic time below four and one-half hours1 the shortest yet known4 ,but ,pickering maintains that1 in observations of this kind upon a single star1 the precision is such that the reality of the difference1 small though it be1 is beyond reasonable doubt4 ,taking ,pickering's law of change as a basis1 ,myers has represented the light-curve of ,u ,pegasi on a theory similar to that which he constructed for ,beta ,lyr4 ,his conclusion is that1 in the present case1 the two bodies which form the visible star are in actual contact4 ,a remarkable historic feature of the case is that ,poincar has recently investigated1 by purely mathematical methods1 the possible forms of revolving fluid masses in a condition of equilibrium1 bringing out a number of such forms previously unknown4 ,one of these1 which he calls the apiodal form1 consists of two bodies joined into one1 and it is this which ,myers finds for ,u ,pegasi4 ,quite similar to these two cases is that of ,zeta ,herculis4 ,this star1 ordinarily of the seventh magnitude1 was found1 at ,potsdam1 in #ahid1 to diminish by about one magnitude4 ,repeated observations elsewhere indicate a period of very nearly four days4 ,actually it is now found to be only ten minutes less than four days4 ,the result was that during any one season of observation the minima occur at nearly the same hour every night or day4 ,to an observer situated in such longitude that they occur during the day1 they would1 of course1 be invisible4 ,continued observations then showed a secondary minimum1 occurring about half-way between the principal minima hitherto observed4 ,it was then found that these secondary minima really occur between one and two hours earlier than the mid-moment1 so that the one interval would be between forty-six and forty-seven hours and the other between forty-nine and fifty4 ,the time which it takes the star to lose its light and regain it again is about ten hours4 ,more recent observations1 however1 do not show this inequality1 so that there is probably a rapid motion of the pericenter of the orbit4 ,it will be seen that this star combines the ,algol and ,beta ,lyr types4 ,it is an ,algol star in that its light remains constant between the eclipses4 ,it is of the ,beta ,lyr type in the alternate minima being unequal4 ,from a careful study1 ,seliger and ,hartwig derived the following particulars respecting this system3 ,diameter of principal star1 #ae1jjj1jjj kilometers4 ,diameter of smaller star1 #ab1jjj1jjj kilometers4 ,mass of the larger star1 #agb times sun's mass4 ,mass of the smaller star1 #id times sun's mass4 ,distance of centers1 #de1jjj1jjj kilometers4 ,time of revolution1 #c;d4 #bc;h4 #dim4 #cb4gs4 ,it must be added that the data for these extraordinary numbers are rather slender and partly hypothetical4 ,beta ,lyr is always of the same brightness at the same hour of its period1 and ,algol has always the same magnitude at minimum4 ,it is true that the length of the period varies slowly in the case of these stars4 ,but this may arise from the action of other invisible bodies revolving around the visible stars4 ,this general uniformity is in accord with the theory which attributes the apparent variations to the various aspects in which we see one and the same system of revolving stars4 ,another variable star showing some unique features is ,eta ,aquil4 ,what gives it special interest is that spectroscopic observations of its radial motion show it to have a dark body revolving round it in a very eccentric orbit1 and in the same time as the period of variation4 ,it might therefore be supposed that we have here a star of the ,algol or ,beta ,lyr type4 ,but such is not the case4 ,there is nothing in the law of variation to suggest an eclipsing of the bright star1 nor does it seem that the variations can readily be represented by the varying aspects of any revolving system4 ,the orbit of this star has been exhaustively investigated by ,wright from ,campbell's observations of the radial motion4 ,the laws of change in the system are shown by the curves below1 which are reproduced1 in great part1 from ,wright's paper in the #8,astrophysical ,journal4' ,illustration3 ,,fig4 #d4 ,,light-,,curve ,,and ,,radial ,,velocity ,,of ,,eta ,,aquil4 ,the lower curve is the light-curve of the star during a period of #g4afg days4 ,starting from a maximum of #c4e mag41 it sinks1 in the course of #e days1 to a minimum of #d4gm4 ,it was found by ,schwab that the diminution is not progressive1 but that a secondary maximum of #c4hm4 is reached at the end of the second day4 ,after reaching the principal minimum it rises rapidly to the principal maximum in #b days4 ,the upper curve shows the radial velocity of the star during the period of variation4 ,it will be seen that the epoch of greatest negative velocity1 which referred to the center of mass of the system1 is #af4b km4 per second1 occurs at the time of maximum brightness4 ,the greatest positive velocity1 #bc4i km41 occurs during the sixth day of the period just after the time of minimum brightness4 ,finally1 the moments of inferior and superior conjunction of the dark body with the bright one are neither of them an epoch of minimum brightness1 which takes place half-way between the two4 ,the most plausible conclusion we can draw is that the light of the star is affected by the action of the dark body during its revolution4 ,but how the change may be produced we cannot yet say4 ,,classification ,,of ,,variable ,,stars4 ,a classification of variable stars1 based on the period of variation and the law of change1 was proposed by ,pickering4 ,it does not1 however1 seem that a hard and fast line can yet be drawn between different types and classes of these bodies1 one type running into another1 as we have found in the case of the ,algol and ,beta ,lyr types4 ,yet the discovery of the cause of the variation in these types makes it likely that a division into two great classes1 dependent on the cause of variation1 is possible4 ,we should then have3 7#a7 ,stars1 or systems1 constituting to vision a single star1 of which the apparent variability arises from the rotation of the system as a whole1 or from the revolution of its components around each other4 7#b7 ,stars of which the changes arise from other and as yet unknown causes4 ,the main feature of the stars of the first class is that we are under no necessity of supposing any actual change in the amount of light which they emit4 ,their apparent variations are purely the effect of perspective1 arising from the various aspects which they present to us during their revolution round each other4 ,if we could change our point of view so that the plane of the orbit of ,algol's planet no longer passed near our system1 ,algol would no longer be a variable star4 ,under the same circumstances the apparent variations in a star of the ,beta ,lyr type would cease to be noticeable1 if they did not disappear entirely4 ,the stars of this class are also distinguished by the uniformity and regularity with which they go through their cycle of change4 ,the stars of the other class1 which we may call the ,omicron ,ceti type1 are different not only in respect to the length of the period1 but in the character of the variation4 ,there are certain general laws of variation and irregularities of brightness which stars of this class go through4 ,starting from the time of the minimum1 the increase of light is at first very slow4 ,it grows more and more rapid as the maximum is approached1 in which time there may be as great an increase in two or three days as there formerly was in a month4 ,the diminution of light is generally slower than the increase4 ,the magnitude at corresponding times in different periods may be very different4 ,thus1 as we have already remarked1 ,omicron ,ceti is ten times as bright at some maxima as it is at others4 ,the periods also1 so far as they have been made out1 vary more widely than those of stars of the other type4 ,the idea has sometimes been entertained that these variations of light are due to a revolution of the star on its axis4 ,a very little consideration will1 however1 show that this explanation cannot be valid4 ,however bright a star might be on one side1 or however dark on the other1 any one region of its surface would be visible to us half the time and a change of brightness from different degrees of brilliancy on different sides would be gradual and regular4 ,it is not impossible that the variability may be in some way connected with the action of a body revolving round the star4 ,this seems to be the case with ,eta ,aquil4 ,the radial motion of this object shows the existence of a dark body revolving round it in the same period as that of the star's variation4 ,from what has been said1 it will be seen that1 although a sharp line cannot be drawn1 there seems to be some distinction between the stars of short and long periods4 ,the number of stars which have been known to belong to the first class is quite small1 only about fifteen1 all told4 ,on the other hand1 there are still left some stars having a period less than ten days1 which are otherwise not distinguishable from the ,omicron ,ceti type4 ,it seems quite likely that the variations in the periods of these stars are1 in some way1 connected with the revolution of bright or dark bodies round them4 ,they also vary more widely than those of stars of the other two types4 ,this might easily happen in the case of stars really variable through a cycle of changes going on in consequence of the action of interior causes4 ,the periodic stars of short period1 which have not been recognized as of the ,algol or ,beta ,lyr type1 form an interesting subject of study4 ,although the separation between them and the stars of long period is not sharp1 it seems likely to have some element of reality in it4 ,but no conclusions on the subject can be reached until the light-curves of a large number of them are carefully drawn2 and this requires an amount of patient and accurate observation which cannot be carried out for years to come4 ,,suspected ,,variations ,,in ,,the ,,color ,,of ,,stars4 ,the question whether certain stars vary in color without materially changing their brightness has sometimes been raised4 ,this was at one time supposed to be the case with one of the stars of ,ursa ,major4 ,this suspected variation has not1 however1 been confirmed1 and it does not seem likely that any such changes take place in the color of stars not otherwise variable4 ,,possible ,,secular ,,variations ,,in ,,the ,,brilliancy ,,of ,,stars4 ,all the variations we have hitherto considered take place with such rapidity that they can be observed by comparisons embracing but a short interval of time--a few days or months at the outside4 ,a somewhat different question of great importance is still left open4 ,may not individual stars be subject to a secular variation of brilliancy1 meaning by this term a change which would not be sensible in the course of only one generation of men1 but admitting of being brought out by a comparison of the brightness of the stars at widely distant epochs8 ,is it certain that1 in the case of stars which we do not recognize as variable1 no change has taken place since the time of ,hipparchus and ,ptolemy8 ,this question has been investigated by ,c4 ,s4 ,pierce and others4 ,the conclusion reached is that no real evidence of any change can be gathered4 ,the discrepancies are no greater than might arise from errors of estimates4 ,there is1 however1 an analogous question which is of great interest and has been much discussed in recent times4 ,in several ancient writings the color of ,sirius is described as red4 ,this fact would1 at first sight1 appear to afford very strong evidence that1 within historic times1 the color of the brightest star in the heavens has actually changed from red to a bluish white4 ,two recent writers have examined the evidence on this subject most exhaustively and reached opposite conclusions4 ,the first of these was ,dr4 ,t4 ,j4 ,j4 ,see1 who collated a great number of cases in which ,sirius was mentioned by ancient writers as red or fiery1 and thus concluded that the evidence was in favor of a red color in former times4 ,shortly afterwards1 ,schiaparelli examined the evidence with equal care and thoroughness and reached an opposite conclusion1 showing that the terms used by the ancient authors1 which might have indicated redness of color1 were susceptible of other interpretations2 they might mean fiery1 blazing1 etc41 as well as red in color1 and were therefore probably suggested by the extraordinary brightness of ,sirius and the strangeness with which it twinkled when near the horizon4 ,in this position a star not only twinkles1 but changes its color rapidly4 ,this change is not sensible in the case of a faint star1 but if one watches ,sirius when on the horizon1 it will be seen that it not only changes in appearance1 but seems to blaze forth in different colors4 ,it seems to the writer that this conclusion of ,schiaparelli is the more likely of the two4 ,from what we know of the constitution of the stars1 a change in the color of one of these bodies in so short a period of time as that embraced by history is so improbable as to require much stronger proofs than any that can be adduced from ancient writers4 ,in addition to the possible vagueness or errors of the original writers1 we have to bear in mind the possible mistakes or misinterpretations of the copyists who reproduced the manuscripts4 ,,the ,,parallaxes ,,of ,,the ,,stars4 ,it needs only the most elementary conceptions of space1 direction and motion to see that1 as the earth makes its vast swing from one extremity of its orbit to the other1 the stars1 being fixed1 must have an apparent swing in the opposite direction4 ,the seeming absence of such a swing was in all ages before our own one of the great stumbling blocks of astronomy4 ,it was the base on which ,ptolemy erected his proof that the earth was immovable in the center of the celestial sphere4 ,it was felt by ,copernicus to be a great difficulty in the reception of his system4 ,it led ,tycho ,brahe to suggest a grotesque combination of the ,ptolemaic and ,copernican systems1 in which the earth was the center of motion1 round which the sun revolved1 carrying the planets with it4 ,with every improvement in their instruments1 astronomers sought to detect the annual swing of the stars4 ,each time that increased accuracy in observations failed to show it1 the difficulty in the way of the ,copernican system was heightened4 ,how deep the feeling on the subject is shown by the enthusiastic title1 ,copernicus ,triumphans1 given by ,horrebow to the paper in which1 from observations by ,roemer1 he claimed to have detected the swing4 ,but1 alas1 critical examination showed that the supposed inequality was produced by the varying effect of the warmth of the day and the cold of the night upon the rate of the clock used by the observer1 and not by the motion of the earth4 ,hooke1 a contemporary of ,newton1 published an attempt to determine the parallax of the stars1 under the title of 8,an ,attempt to ,prove the ,motion of the ,earth10 but his work was as great a failure as that of his predecessors4 ,had it not been that the proofs of the ,copernican system had accumulated until they became irresistible1 these repeated attempts might have led men to think that perhaps1 after all1 ,ptolemy and the ancients were somehow in the right4 ,the difficulty was magnified by the philosophic views of the period4 ,it was supposed that ,nature must economize in the use of space as a farmer would in the use of valuable land4 ,the ancient astronomers correctly placed the sphere of the stars outside that of the planets1 but did not suppose it far outside4 ,that ,nature would squander her resources by leaving a vacant space hundreds of thousands of times the extent of the solar system was supposed contrary to all probability4 ,the actual infinity of space2 the consideration that one had only to enlarge his conceptions a little to see spaces a thousand times the size of the solar system look as insignificant as the region of a few yards round a grain of sand1 does not seem to have occurred to anyone4 ,considerations drawn from photometry were also lost sight of1 because that art was still undeveloped4 ,kepler saw that the sun might well be of the nature of a star2 in fact1 that the stars were probably suns4 ,had he and his contemporaries known that the light of the sun was more than ten thousand million times that of a bright star1 they would have seen that it must be placed at one hundred thousand times its present distance to shine as a bright star4 ,if1 then1 the stars are as bright as the sun1 they must be one hundred thousand times as far away1 and their annual parallax would then have been too small for detection with the instruments of the time4 ,such considerations as this would have removed the real difficulty4 ,the efforts to discover stellar parallax were1 of course1 still continued4 ,bradley1 about #agdj1 made observations on ,draconis1 which passed the meridian near his zenith1 with an instrument of an accuracy before unequalled4 ,he thus detected an annual swing of #bj on each side of the mean4 ,but this swing did not have the right phase to be due to the motion of the earth2 the star appeared at one or the other extremity of its swing when it should have been at the middle point1 and vice versa4 ,what he saw was really the effect of aberration1 depending on the ratio of the velocity of the earth in its orbit to the velocity of light4 ,it proved the motion of the earth1 but in a different way from what was expected4 ,all that ,bradley could prove was that the distances of the stars must be hundreds of thousands of times that of the sun4 ,an introductory remark on the use of the word parallax may preface a statement of the results of researches now to be considered4 ,in a general way1 the change of apparent direction of an object arising from a change in the position of an observer is termed parallax4 ,more especially1 the parallax of a star is the difference of its direction as seen from the sun and from that point of the earth's orbit from which the apparent direction will be changed by the greatest amount4 ,it is equal to the angle subtended by the radius of the earth's orbit1 as seen from the star4 ,the simplest conception of an arc of one second is reached by thinking of it as the angle subtended by a short line at a distance of two hundred and six thousand times its length4 ,to say that a star has a parallax of #a would therefore be the same thing as saying that it was at a distance of a little more than two hundred thousand times that of the earth from the sun4 ,a parallax of one-half a second implies a distance twice as great2 one of one-third1 three times as great4 ,a parallax of #jbj implies a distance of more than a million times that of our unit of measure4 ,the first conclusive result as to the extreme minuteness of the parallax of the brighter stars was reached by ,struve1 at ,dorpat1 about #ahcj4 ,in the high latitude of ,dorpat the right ascension of a star can be determined with great precision1 not only at the moment of its transit over the meridian1 but also at transit over the meridian below the pole1 which occurs twelve hours later4 ,he1 therefore1 selected a large group of stars which could be observed twice daily in this way at certain times of the year1 and made continuous observations on them through the year4 ,it was not possible1 by this method1 to certainly detect the parallax of any one star4 ,what was aimed at was to determine the limit of the average parallax of all the stars thus observed4 ,the conclusion reached was that this limit could not exceed one-tenth of a second and that the average distance of the group could not1 therefore1 be much less than two million times the distance of the sun2 if1 perchance1 some stars were nearer than this1 others were more distant4 ,by a singular coincidence1 success in detecting stellar parallax was reached by three independent investigators almost at the same time1 observing three different stars4 ,to ,bessel is commonly assigned the credit of having first actually determined the parallax of a star with such certainty as to place the result beyond question4 ,the star having the most rapid proper motion on the celestial sphere1 so far as known to ,bessel1 was #fa ,cygni1 which is1 however1 only of the fifth magnitude4 ,this rapid motion indicated that it was probably among the stars nearest to us1 much nearer1 in fact1 than the faint stars by which it is surrounded4 ,after several futile attempts1 he undertook a series of measurements with a heliometer1 the best in his power to make1 in ,august1 #ahcg1 and continued them until ,october1 #ahch4 ,the object was to determine1 night after night1 the position of #fa ,cygni1 relative to certain small stars in its neighborhood4 ,then he and his assistant1 ,sluter1 made a second series1 which was continued until #ahdj4 ,all these observations showed conclusively that the star had a parallax of about #j4ce4 ,while ,bessel was making these observations1 ,struve1 at ,dorpat1 made a similar attempt upon ,alpha ,lyr4 ,this star1 in the high northern latitude of ,dorpat1 could be accurately observed throughout almost the entire year4 ,it is one of the brightest stars near the ,pole and has a sensible proper motion4 ,there was1 therefore1 reason to believe it among the nearest of the stars4 ,the observations of ,struve extended from #ahce to ,august1 #ahch1 and were1 therefore1 almost simultaneous with the observations made by ,bessel on #fa ,cygni4 ,he concluded that the parallax of ,alpha ,lyr was about one-fourth of a second4 ,subsequent investigations have1 however1 made it probable that this result was about double the true value of the parallax4 ,the third successful attempt was made by ,henderson1 of ,england1 astronomer at the ,cape of ,good ,hope4 ,he found from meridian observations that the star ,alpha ,centauri had a parallax of about #a4 ,this is a double star of the first magnitude1 which1 being only #cj from the south celestial pole1 never rises in our latitudes4 ,its nearness to us was indicated not only by its magnitude1 but also by its considerable proper motion4 ,although subsequent investigation has shown the parallax of this body to be less than that found by ,henderson1 it is1 up to the time of writing1 the nearest star whose distance has been ascertained4 ,the extreme difficulty of detecting movements so slight as those we have described1 when they take six months to go through their phases1 will be obvious to the reader4 ,he would be still more impressed with it when1 looking through a powerful telescope at any star1 he sees how it flickers in consequence of the continual motions going on in the air through which it is seen and how difficult it must be to fix any point of reference from which to measure the change of direction4 ,the latter is the capital difficulty in measuring the parallax4 ,how shall we know that a star has changed its direction by a fraction of a second in the course of six months8 ,there must be for this purpose some standard direction from which we can measure4 ,the most certain of these standard directions is that of the earth's axis of rotation4 ,it is true that this direction varies in the course of the year1 but the amount of the variation is known with great precision1 so that it can be properly allowed for in the reduction of the observations4 ,the angle between the direction of a star and that of the earth's axis1 the latter direction being represented by the celestial pole1 can be measured with our meridian instruments4 ,it is1 in fact1 the north polar distance of the star1 or the complement of its declination4 ,if1 therefore1 the astronomer could measure the declination of a star with great precision throughout the entire year1 he would be able to determine its parallax by a comparison of the measures4 ,but it is found impossible in practice to make measures of so long an arc with the necessary precision4 ,the uncertain and changing effect of the varying seasons and different temperatures of day and night upon the air and the instrument almost masks the parallax4 ,after several attempts with the finest instruments1 handled with the utmost skill1 to determine stellar parallax from the declinations of the stars1 the method has been practically abandoned4 ,the method now practiced is that of relative parallax4 ,by this method the standard direction is that of a small star apparently alongside one whose parallax is to be measured1 but1 presumably1 so much farther away that it may be regarded as having no parallax4 ,in this assumption lies the weak point of the method4 ,can we be sure that the smaller stars are really without appreciable parallax8 ,until recent times it was generally supposed that the magnitude of the stars afforded the best index to their relative distances4 ,if the stars were of the same intrinsic brilliancy1 the amount of light received from them would1 as already pointed out1 have been inversely as the square of the distance4 ,although there was no reason to suppose that any such equality really existed1 it would still remain true that1 in the general average1 the brighter stars must be nearer to us than the fainter ones4 ,but when the proper motions of stars came to be investigated1 it was found that the amount of this motion afforded a better index to the distance than the magnitude did4 ,the diversity of actual or linear motion is not so wide as that of absolute brilliancy4 ,stars have1 therefore1 in recent times1 been selected for parallax very largely on account of their proper motion1 without respect to their brightness4 ,it is now considered quite safe to assume that the small stars without proper motion are so far away that their parallax is insensible4 ,ever since the time of ,bessel the experience of practical astronomers has tended toward the conclusion that the best instrument for delicate measurements like these is the heliometer4 ,this is an equatorial telescope of which the object glass is divided along a diameter into two semicircles1 which can slide along each other4 ,each half of the object glass forms a separate image of any star at which the telescope may be pointed4 ,by sliding the two halves along each other1 the images can be brought together or separated to any extent4 ,if there are two stars in proximity1 the image of one star made by one-half of the glass can be brought into coincidence with that of the other star made by the other half4 ,the sliding of the two halves to bring about this coincidence affords a scale of measurement for the angular distance of the two stars4 ,the most noteworthy forward steps in improving the heliometer are due to the celebrated instrument-makers of ,hamburg1 the ,messrs4 ,repsold1 aided by the suggestions of ,dr4 ,david ,gill1 astronomer at the ,cape of ,good ,hope4 ,the latter1 in connection with his coadjutor1 ,elkin1 made an equally important step in the art of managing the instrument and hence in determining the parallax of stars4 ,the best results yet attained are those of these two observers and of ,peter1 of ,germany4 ,yet more recently1 ,kapteyn1 of ,holland1 has applied what has seemed to be the unpromising method of differences of right ascension observed with a meridian circle4 ,this method has also been applied by ,flint1 at ,madison1 ,wis4 ,through the skill of these observers1 as well as that of ,brnnow and ,ball1 in applying the equatorial telescope to the same purposes1 the parallax of nearly #ajj stars has been measured with some approach to precision4 ,a rival method to that of the heliometer has been discovered in the photographic telescope4 ,the plan of this instrument1 and its application to such purposes as this1 are extremely simple4 ,we point a telescope at a star and set the clock-work going1 so that the telescope shall remain pointed as exactly as possible in the direction of the star4 ,we place a sensitized plate in the focus and leave it long enough to form an image both of the particular star in view and of all the stars around it4 ,the plate being developed1 we have a permanent record of the relative positions of the stars which can be measured with a suitable instrument at the observer's leisure4 ,the advantage of the method consists in the great number of stars which may be examined for parallax1 and in the rapidity with which the work can be done4 ,the earliest photographs which have been utilized in this way are those made by ,rutherfurd in ,new ,york during the years #ahfj to #ahge4 ,the plates taken by him have been measured and discussed principally by ,rees and ,jacoby1 of ,columbia ,university4 ,before their work was done1 however1 ,pritchard1 of ,oxford1 applied the method and published results in the case of a number of stars4 ,one of the pressing wants of astronomy at the present time is a parallactic survey of the heavens for the purpose of discovering all the stars whose parallax exceeds some definable limit1 say #ja4 ,such a survey is possible by photography1 and by that only4 ,a commencement1 which may serve as an example of one way of conducting the survey1 has been made by ,kapteyn on photographic negatives taken by ,donner at ,helsingfors4 ,these plates cover a square in the ,milky ,way about two degrees on the side1 extending from #ce #ej in declination to #cf #ej1 and from #bj;h4 #am4 in ,r4 ,a4 to #bj;h4 #ajm4 #bds4 ,three plates were used1 on each of which the image of each star is formed twelve times4 ,three of the twelve impressions were made at the epoch of maximum parallactic displacement1 six at the minimum six months later1 and three at the following maximum4 ,the parallaxes found on the plates can only be relative to the general mean of all the other stars1 and must therefore be negative as often as positive4 ,the following positive parallaxes1 amounting to #ja1 came out with some consistency from the measures3 ,star1 ,b4 ,d41 #cigb ,mag4 #h4f ,r4,a4 #bj;h41 #bm4 #js4 ,dec4 #ce4e ,par4 #j4aa ,star1 ,b4 ,d41 #chhc ,mag4 #g4a ,r4,a4 #bj;h41 #bm4 #cs4 ,dec4 #cf4a ,par4 #j4ah ,star1 ,b4 ,d41 #djjc ,mag4 #i4b ,r4,a4 #bj;h41 #dm4 #ehs4 ,dec4 #ce4d ,par4 #j4aj ,star1 ,b4 ,d41 #ciei ,mag4 #g4j ,r4,a4 #bj;h41 #im4 #ads4 ,dec4 #cf4c ,par4 #j4aj ,against these are to be set negative parallaxes of -#j4ji1 -#j4jh and several a little smaller1 which are certainly unreal4 ,the presumption in favor of the actuality of one or more of the above positive values1 which is created by their excess over the negative values1 is offset by the following considerations3 ,the area of the entire sky is more than #dj1jjj square degrees1 or #aj1jjj times the area covered by the ,helsingfors plates4 ,we cannot well suppose that there are #a1jjj stars in the sky with a parallax of #j4aj1 or more without violating all the probabilities of the case4 ,the probabilities of the case are therefore against even one star with such a parallax being found on the plates4 ,yet the cases of these four stars are worthy of further examination1 if any of them are found to have a sensible proper motion4 ,on an entirely different plan is a survey just concluded by ,chase with the ,yale heliometer4 ,it includes such stars having an annual proper motion of #j4je or more as had not already been measured for parallax4 ,the results1 in statistical form1 are these3 #b stars have parallaxes between #i4bj and #j4be4 #f stars have parallaxes between #j4ae and #j4bj4 #aa stars have parallaxes between #j4aj and #j4ae4 #bd stars have parallaxes between #j4je and #j4aj4 #cd stars have parallaxes between #j4jj and #j4je4 #h stars have parallaxes between -#j4je and #j4jj4 #e stars have parallaxes between -#j4aj and -#j4je4 #b stars have parallaxes between -#j4ae and -#j4aj4 -- #ib1 total number of stars4 ,it will be understood that the negative parallaxes found for fifteen of these stars are the result of errors of observation4 ,assuming that an equal number of the smaller positive values are due to the same cause1 and subtracting these thirty stars from the total number1 we shall have sixty-two stars left of which the parallax is real and generally amounts to #j4je1 more or less4 ,the two values approximating to #j4be seem open to little doubt4 ,we might say the same of the six next in the list4 ,the first two belong to the stars #ed ,piscium and ,weisse1 #ag;h41 #cbb4 ,,discussion ,,and ,,correspondence4 ,,the ,,meetings ,,of ,,the ,,american ,,association4 ,the ,american ,association for the ,advancement of ,science has a membership ranging from #a1ijj to #b1jjj4 ,of this number probably at no one time was there an aggregate of #cjj persons present at the recent annual meeting in ,new ,york4 ,when the ,association meets in an ,eastern city the attendance is generally twice if not three times as large as when it convenes in the ,west4 ,so little was made of the recent meeting1 locally or officially1 that an intelligent resident of the city remarked3 8,why1 ,i intended to have attended some of the meetings1 but seeing no reference in the daily papers1 it entirely escaped my mind40 ,of the #b1jjj members1 about #hjj are fellows2 the #a1bjj and more registered as members are1 presumably1 persons devoting little or no time to independent research along scientific lines1 but persons who while not actively so engaged are more than ordinarily interested in the discussion of scientific topics4 ,these have in the past paid dues and attended the meetings of the ,association with more or less regularity4 ,it is a question in the minds of some of the #a1bjj if their attendance at the meetings is desired4 ,their membership1 so far as it relates to the five dollars initiation fee and three dollars dues1 is without question acceptable1 and to persons reading papers in the various sections their presence is preferable to empty seats1 but in view of the fact that during recent years the management of the ,association has eliminated1 so far as possible1 the popular features of the general programme1 the question is reasonably asked3 8,does the management desire the attendance of the #a1bjj1 or is their financial support all that is desired80 ,it was stated some years ago that the purpose of the ,association was to furnish not only an occasion for scientists to present original papers1 but also to interest the public by holding the meetings annually in different parts of the country2 but if attendance is not secured 7by preparation and publication of interesting features of a programme7 no great interest will be awakened by a meeting held in any part of the country4 ,i should like to suggest the following ways of increasing the interest of the meetings3 ,the general daily sessions might be made occasions of rare interest by the introduction of prominent men of science who would make at least brief remarks4 ,this would make it possible for those who have limited time to become familiar with the faces of those whom they would like to know1 and the little #8sample' of scientific thought thrown out would doubtless awaken desire for more4 ,it will be objected that the meetings of the council immediately preceding the general session prevent holding an official meeting at that hour4 ,the public and the #a1bjj would care little whether the session were official or unofficial so it were interesting and instructive4 ,the officers of the several sections could easily secure distinguished representatives of their respective sciences to give brief addresses followed by discussion1 and thus the morning hour would prove an attraction to citizens and others who might be unable to attend the sessions following4 ,again1 citizens1 where the meetings are held1 would be pleased to provide excursions to points of local interest and extend social courtesies1 if they were given in return the mental food in digestible form1 with which the ,association is so amply supplied4 ,it remains with the management to decide whether attendance shall be restricted to the few actively engaged in scientific pursuits1 or whether it shall include the #a1bjj and more who would be glad to avail themselves of the benefits of a programme suited to average scholarship and intellectual capacity4 ,there is no better medium for discussion of the above views than through the widely read pages of ,,the ,,popular ,,science ,,monthly4 ,m4 ,e4 ,d4 ,,trowbridge4 ,detroit1 ,mich4 ,the questions brought up by our correspondent have been carefully considered by all those who are interested in the ,american ,association for the ,advancement of ,science4 ,when the ,association was founded fifty years ago there was no division into sections2 the papers and discussions were intelligible and interesting to all members4 ,at that time there were but few members1 the scientific life of the country was small1 and it was a privilege for a city to entertain the ,association4 ,but fifty years have brought changes in many directions4 ,specialization in science has become essential for its further progress1 and it has been necessary to divide the ,association into numerous sections and to found special societies4 ,hospitality can now only be provided at great expense1 and ,eastern cities no longer regard it as a privilege to entertain the numerous societies that gather within their hotels4 ,the newspapers do not regard a meeting of the ,association as an important event and will not devote space to it4 ,the ,association must do the best it can to adapt itself to existing conditions4 ,the recent meeting in ,new ,york had perhaps the largest attendance of scientific men of any in the history of the ,association with the exception of the anniversary meeting two years ago1 but ,new ,york ,city1 especially in the month of ,june1 is not a desirable place for social functions4 ,it is not reasonable for a member interested in science as an amateur to expect to purchase for three dollars a week's entertainment4 ,his dues secure reduced railway and hotel rates2 he can meet his friends and become acquainted with scientific men2 he can always find on the programme papers that are of interest2 he receives the annual volume of #8,proceedings' and the weekly journal1 #8,science1' the cost of which is five dollars per year4 ,but apart from these direct returns1 he is surely repaid for membership by knowing that he is one of those who are united for the advancement of science in ,america4--,,editor1 ,,popular ,,science ,,monthly4 ,,the ,,color ,,red4 ,,to ,,the ,,editor ,,of ,,the ,,popular ,,science

,flournoy1 entitled #8,des ,indes la ,plante ,mars1',g contains an account of a remarkable case of mental automatism1 or sub-conscious personality4 ,the subject is a young woman of about thirty years1 apparently in good health1 but always of a nervous and imaginative type4 ,she developed tendencies towards lapses of consciousness1 hallucinations and automatic actions2 and these developed later1 under the inspiration of spiritualistic sances1 into a series of cycles1 or automatic dramas1 in which the medium speaks or writes and acts under the influence of several diverse subordinate personalities4 ,in one of these cycles--which1 it must be understood1 are continued from one sitting to another1 although in her intermediate normal life she knows nothing of what she has said or done in the trance--she becomes ,marie ,antoinette1 and is said to act the part with unusual dramatic skill4 ,in another and far more elaborate cycle the scene is transferred to the planet ,mars1 and the houses1 scenery1 plants and animals1 peoples1 customs and goings-on of the planet are described2 sketches are made1 and reproduced in the volume1 of these extra-mundane appearances4 ,still more remarkable is the appearance of the ,martian language1 which in successive sances the subject hears1 speaks1 sees before her in space1 and1 in the end1 even writes4 ,from the mystery of ,mars we are taken to the equally mysterious ,hindu cycle2 here the medium becomes an ,indian princess of the fifteenth century1 reveals her history and that of her associates in the ,oriental life1 tells of herself as ,simandini2 of ,sivrouka1 her prince1 who reigned over ,kanara and built in #adja the fortress of ,tschandraguiri4 ,wonderful to relate1 these names are not fictitious1 but are mentioned by one ,de ,marls in a volume published in #ahbh2 the author1 however1 does not enjoy a high reputation as a historian4 ,when occasional utterances of the ,hindu princess are taken down1 they are found in part to have close resemblance to ,sanskrit words2 while in her normal condition the medium is as ignorant of ,sanskrit as she is of any language except ,french1 and is entirely ignorant of both ,de ,marls and the people of ,india five hundred years ago4 ,surely this is a tale1 bristling with mystery and improbability1 which1 if told carelessly or with a purpose1 we should dismiss as a willful invention6 ,m4 ,flournoy has been unusually successful in revealing the starting points of the several automatisms and of connecting them with intelligible developments of the medium's mental life2 and the manifestations1 though they remain as remarkable examples of unconscious memory and elaboration of ideas1 nowhere transcend these limitations4 ,the sketches of ,martian scenery are clearly ,japanesque or vaguely ,oriental2 the ,martian language is pronounced an #8infantile' production1 and is clearly modeled after the ,french1 the characters being the result of an attempt to make them as oddly different from our own as possible2 the ,sanskrit goes no farther than what one could get from a slight acquaintance with a ,sanskrit grammar2 and while there is a copy of ,de ,marls in the ,geneva ,library 7where the medium lives71 no connection can be established between either ,de ,marls or the grammar and the subject of this study4 ,most of this knowledge of these remarkable sub-conscious states would have been impossible were it not for #8spirit control' of one ,leopold1 who1 in accordance with the doctrine of reincarnation which permeates the several cycles1 was in his life the famous ,cagliostro4 ,by suitable suggestion1 ,leopold can be induced to make the entranced subject speak1 write1 draw1 or interpret her strange messages from other worlds2 and where ,leopold says #8nay' all progress is stopped4 ,this case has many analogies with other cases that have been recorded1 but goes beyond most of them in the complexity and bizarre character of the unconscious elaborations and in the feats of memory and creative imagination which it entails4 ,these accomplishments1 it should be well understood1 never appeared suddenly or fully developed1 but only after a considerable period of subliminal preparation1 and then only hesitatingly1 and little by little1 just as is the case with the acquisitions of normal consciousness2 and all these acquisitions bear unmistakable marks of belonging to the same person4 ,the special value of this account thus lies in the accuracy of the description and the success with which the account has been made thoroughly intelligible and significant4 ,g ,the book has just been published by the ,harpers in an ,english version1 under the title #8,she ,lived in ,mars4' ,,the ,,mosquitoes ,,of ,,the ,,united ,,states4 ,dr4 ,l4 ,o4 ,howard1 the entomologist of the ,united ,states ,department of ,agriculture1 has just published a bulletin entitled1 8,notes on the ,mosquitoes of the ,united ,states3 ,giving some ,account of their ,structure and ,biology1 with ,remarks on ,remedies40 ,the author has1 for some years1 been interested in the general subject of the biology of mosquitoes and of remedies to be used against them1 and has brought together in this bulletin all the published and unpublished notes which he has been collecting during this period4 ,the bulletin contains synoptic tables of all ,north ,american mosquitoes1 prepared by ,mr4 ,d4 ,w4 ,coquillett1 and gives detailed facts regarding the geographical distribution of the different species mentioned4 ,all the five ,north ,american genera are illustrated and full1 illustrated accounts are given of the life history of the two principal genera1 ,culex and ,anopheles1 as studied in ,culex pungens and ,anopheles quadrimaculatus4 ,the author calls special attention to the two genera of large mosquitoes1 ,psorophora and ,megarhinus1 and urges the importance of the study of these two genera1 especially by physicians in the ,south1 in regard to their possible relation to the spread of malaria4 ,considerable space is given to the subject of remedies1 the principal ones considered being kerosene on breeding pools1 the introduction of fish in fishless ponds1 the artificial agitation of water and general community work4 ,it is clearly shown not only that the mosquito may be1 in many localities1 readily done away with at comparatively slight expense1 but that by careful work many malarious localities may be made healthy4 ,the subject of mosquitoes and malaria is not discussed in the bulletin1 which contains simply references to available papers on this subject1 like the article by ,dr4 ,patrick ,manson1 published in ,,the ,,popular ,,science ,,monthly for ,july1 the aim of the author being to bring together all available facts about the mosquitoes of the ,united ,states1 in order to assist physicians who are studying the malarial relation from the point of view of local conditions4 ,,the ,,progress ,,of ,,science4 ,the ,british1 ,french and ,german ,associations for the ,advancement of ,science have held their annual meetings in the course of the past month4 ,in each of these countries and in most other ,european countries1 as well as in ,america1 there are migratory scientific congresses of the same general character4 ,as these have grown up somewhat independently1 they evidently meet a common need4 ,science cannot be advanced by a man working independently and in isolation4 ,the printing press was essential to the beginnings of modern science1 while at the same time it was usual for the scientific student to travel from place to place that he might learn and teach4 ,then in the seventeenth and eighteenth centuries1 as the cultivation of science became more general1 royal academies were founded4 ,the ,royal ,society was established at ,london in #affj under the patronage of ,charles ,,ii41 the ,academy of ,sciences at ,paris in #afff under ,louis ,,xiv41 the ,royal ,academy at ,berlin in #agjj under ,frederick ,i41 the ,imperial ,academy at ,st4 ,petersburg in #agbd under ,peter the ,great1 and in other cities similar academies were founded under similar auspices4 ,then in the first half of the present century1 as science continued to grow1 the more democratic organizations for the advancement of science were established4 ,the ,society of ,german ,scientific ,men and ,physicians was formed1 chiefly through the efforts of ,humboldt1 in #ahbb2 the ,swiss ,association in #ahbi1 and the ,british ,association in #ahca4 ,our own ,association was established in #ahdg1 but was then the intergrowth of a society dating from #ahdj4 ,these associations are significant of the spread of science among all the people4 ,science is no longer the concern of a few men under royal patronage1 but the two great movements of the present century--the growth of democracy and the growth of science--have united for their common good4 99 99 99 99 99 ,the ,british ,association held its annual meeting at ,bradford1 beginning on ,september #e1 under the presidency of ,sir ,william ,turner1 professor of anatomy in the ,university of ,edinburgh4 ,we are able to publish1 from a copy received in advance of its delivery1 his presidential address1 which traces the growth during the present century of knowledge regarding fundamental biological problems4 ,the addresses of the presidents before the sections are usually written in a way that can be readily understood by those who are not specialists1 and are consequently of greater interest to a general audience than some of the corresponding addresses before the ,american ,association4 ,the addresses at ,bradford were3 ,before the section of mathematical and physical science ,dr4 ,joseph ,larmor discussed recent developments of physics with special reference to the extent to which explanation can be reduced purely to description2 before the section of chemistry ,prof4 ,h4 ,w4 ,perkin argued that radical changes should be made in the methods of teaching inorganic chemistry2 before the section of geology ,prof4 ,w4 ,j4 ,sollas spoke of the development of the earth1 including the different critical periods in its history2 before the section of zology ,dr4 ,r4 ,h4 ,traquair chose as his subject the bearing of fossil fishes on the doctrine of descent2 before the section of geography ,sir ,george ,robertson considered certain geographical aspects of the ,british ,empire and the changes brought about by improved means of intercommunication2 before the section of economic science and statistics ,major ,p4 ,g4 ,craigie spoke of the use of statistics in agriculture2 before the section of mechanical science ,sir ,alexander ,binnie traced the historical development of science2 before the section of anthropology ,prof4 ,john ,rhys dealt with the ethnology of the ,british ,isles1 with special reference to language and folk-lore2 before the section of botany ,prof4 ,sidney ,h4 ,vines reviewed the development of botany during the present century4 ,in addition to these addresses1 evening discourses were given by ,prof4 ,francis ,gotch on #8,animal ,electricity1' and by ,prof4 ,w4 ,stroud on #8,range ,finders4' ,the usual lecture to workingmen was given by ,prof4 ,sylvester ,p4 ,thompson1 his subject being #8,electricity in the ,industries4' 99 99 99 99 99 ,bradford is situated in the coal regions1 and is an industrial center devoted especially to the manufacture of textiles4 ,more attention was paid to local interests than is usual at the meetings of the ,american ,association4 ,an exhibit was arranged to show the development of the elaborate fabrics from the unwashed fleeces1 and another consisting of a collection of carboniferous fossils found in the neighborhood4 ,a joint discussion was arranged between the sections of zology and botany on the conditions which existed during the growth of the forests which supplied material for the coal1 and there were a number of papers devoted to the coal measures and the fossils which they contain4 ,another subject connected with the place of meeting was the report of the committee on the underground water system in the carboniferous limestone4 ,by the use of chemicals the course of the underground waters has been traced1 including their percolation through rock fissures1 and excursions were made to the site of the experiments4 ,the local industries received treatment from several sides4 ,among other discussions of more than usual interest was that on #8,ions' before the physical section and on #8,what is a ,metal8' before the chemical section4 ,features of popular interest were accounts of adventures in ,asia1 ,africa and the ,antarctic regions1 by ,captain ,deasy1 ,captain ,george and ,mr4 ,borchgrevinck1 respectively1 and ,major ,ross's paper on #8,malaria and ,mosquitoes4' 99 99 99 99 99 ,the ,french ,association met at ,paris in the month of ,august1 with the numerous other congresses4 ,general ,sebert1 in his presidential address1 reviewed the progress of the mechanical industries during the century and devoted the last third of his time to a discussion of international bibliography1 but without mentioning the ,international ,catalogue which now seems to be an accomplished fact4 ,the secretary of the ,association1 in his review of the year1 devoted special attention to the joint meetings of the ,british and ,french associations last summer at ,dover and ,calais4 ,the treasurer was able to make a report that the treasurers of other national associations will envy4 ,the capital is over #bej1jjj1 and the income from all sources about #ag1jjj1 of which about #c1jjj was awarded for the prosecution of research and to defray the cost of publication of scientific monographs4 ,the national association for the advancement of science of ,germany--the #8,gesellschaft deutscher ,naturforscher und ,aerzte'--held its annual meeting at ,aachen toward the middle of ,september4 ,an account of the proceedings has not yet reached us1 but the congresses are always largely attended and the combination of addresses of general interest1 of special papers before the numerous sections and of social functions1 is perhaps more effective than in any other society4 ,it also appears to be a considerable advantage for medical men and scientific men to meet together4 99 99 99 99 99 ,while from the scientific point of view the present century has been notable for the development of national associations for the advancement of science1 its latter decades have witnessed a growth of international scientific meetings which may be expected to become dominant in the twentieth century4 ,there are at least one hundred congresses1 having more or less reference to science1 meeting at ,paris during the present summer4 ,perhaps the most noteworthy of these1 from the point of view of the organization of science1 is the ,international ,association of ,academies1 which was established last year at a conference held at ,wiesbaden4 ,in this ,association eighteen of the great academies of the world1 including our own ,national ,academy of ,sciences1 have been united to promote the interests of science4 ,literature is also included--of the eighteen academies1 twelve include in their scope both science and literature1 four are devoted to science only and two to literature only4 ,it is planned to have a general meeting every three years1 to which each academy will send as many delegates as it regards as desirable1 though each academy will have but one vote4 ,in the interval between the general meetings1 the business of the ,association is to be directed by a committee1 on which each academy is represented4 ,the object of the ,association is to plan and promote scientific work of international interest which may be proposed by one of the constituent academies1 and generally to promote scientific relations between different countries4 ,the ,royal ,society has proposed the measurement1 by international coperation1 of an extended arc of the meridian in the interior of ,africa4 99 99 99 99 99 ,the ,international ,congress of ,physics marked an advance owing to the fact that it met for the first time this year1 and it appears that the proceedings were of unusual interest4 ,this was in a large measure due to the arrangements of the ,french ,physical ,society1 which did not simply make up a programme from a mass of heterogeneous researches1 but secured some eighty reports on the present condition of physical science4 ,these were prepared by many of the leading physicists of the world and when published--as they are about to be in three volumes--will set forth the condition of the science with completeness and authority4 ,there were in all seven sections4 ,in the first1 which was concerned with measurement1 in addition to numerous reports several propositions were brought forward in regard to units1 which1 being international in character1 are specially fitted for discussion at such a congress4 ,as the members1 however1 were not in most cases delegates from governments and scientific bodies1 no definite action was taken1 though some recommendations were made4 ,the decimalization of time was not recommended1 nor was the proposal to give a name to units of velocity and acceleration4 ,it was1 however1 decided that the #8,barrie' be adopted as the unit of pressure4 ,the other sections were for mechanical physics1 for optics1 for electricity1 for magneto-optics and radio-activity1 for cosmical physics and for biological physics4 ,among the reports and papers of commanding interest only two can be mentioned--the introductory address by ,m4 ,poincar1 discussing the relations between experimental and mathematical physics1 and one by ,lord ,kelvin on the waves produced in an elastic solid traversed by a body acting on it by attraction or repulsion1 in which1 from a strictly mathematical point of view1 he advanced the hypothesis of a movable atom surrounded by an immovable ether4 ,in addition to various receptions1 a session was held at the ,sorbonne1 where ,messrs4 ,becquerel and ,curie gave demonstrations with radio-active substances1 and one at the ,ecole ,polytechnique1 where ,president ,cornu showed apparatus which had been used in the determination of the velocity of light4 ,at the close of the congress the foreign secretaries placed a crown on the tomb of ,fresnel4 99 99 99 99 99 ,while a physical congress was meeting at ,paris this year for the first time1 the ,geological ,congress1 which was one of the first international congresses to be organized1 held its eighth session1 beginning on ,august #af4 ,america1 in spite of the number and importance of the inventions it has given to the world1 has not as yet done its share for the advancement of physical science1 but in geology it occupies a foremost place4 ,it was natural1 therefore1 that while ,american physicists were scarcely represented on the programme of the ,physical ,congress1 they occupied a prominent place on the programme of geological papers4 ,among the three hundred members present1 the representation from ,america included ,messrs4 ,stevenson1 ,hague1 ,osborn1 ,ward1 ,willis1 ,white1 ,cross1 ,scott1 ,todd1 ,kunz1 ,choquette1 ,adams1 ,mathew and ,rice1 and they presented a number of the more important papers4 ,m4 ,karpinsky1 the retiring president1 gave the opening address1 which was followed by an address of welcome by ,m4 ,gaudry1 the president of the congress4 ,a geological congress can offer special attractions in the way of excursions1 and these were admirably arranged on the present occasion--both the shorter excursions to the classic horizons in the neighborhood of ,paris and the more extended ones that followed the close of the meeting4 ,the guide for the twenty long excursions and numerous shorter trips1 prepared by the leading ,french geologists1 was an elaborately illustrated volume representing the present condition of our knowledge of ,french geology4 ,the ninth geological congress will be held at ,vienna three years hence4 99 99 99 99 99 ,the ,international ,congress of ,mathematics met for the second time at ,paris1 though there had been a preliminary meeting on the occasion of the ,chicago ,exposition4 ,there were about two hundred and twenty-five mathematicians in attendance1 including seventeen from the ,united ,states4 ,m4 ,poincar presided1 and the vice-presidents1 some of whom were not present1 were ,messrs4 ,czuber1 ,gordon1 ,greenhill1 ,lindelf1 ,lindemann1 ,mittag-,leffler1 ,moore1 ,tikhomandritzky1 ,volterra1 ,zeuthen and ,geiser4 ,the sections and their presiding officers were as follows3 7#a7 ,arithmetic and ,algebra3 ,hilbert2 7#b7 ,analysis3 ,painlev2 7#c7 ,geometry3 ,darboux2 7#d7 ,mechanics and ,mathematical ,physics3 ,larmor2 7#e7 ,bibliography and ,history3 ,prince ,roland ,bonaparte2 7#f7 ,teaching and ,methods3 ,cantor4 ,valuable papers were presented by ,m4 ,cantor on works and methods concerned with the history of mathematics1 by ,professor ,hilbert on the future problems of mathematics and by ,professor ,mittag-,leffler on an episode in the life of ,weierstrass1 but the programme appears to have been not very full nor particularly interesting4 ,time was found for a half-day's discussion of a universal language1 but not to carry into effect the plans begun at ,zurich three years ago for a mathematical bibliography4 ,the next congress will meet four years hence in ,germany1 probably at ,baden-,baden4 99 99 99 99 99 ,the untimely death of ,james ,edward ,keeler1 director of the ,lick ,observatory1 is a serious blow to astronomy and to science4 ,born at ,la ,salle1 ,ill41 forty-three years ago1 he was educated at the ,johns ,hopkins ,university and in ,germany4 ,when only twenty-one years old he observed the solar eclipse of #ahgh1 and drew up an excellent report4 ,three years later he was a member of the expedition to ,mt4 ,whitney under ,professor ,langley1 whose assistant he had become at the ,allegheny ,observatory1 and whose bolometric investigations owe much to him4 ,he became astronomer at the ,lick ,observatory while it was in course of erection1 and in #ahia he succeeded ,professor ,langley as director of the ,allegheny ,observatory4 ,he was called to the directorship of the great ,lick ,observatory in #ahih4 ,keeler's work in astrophysics1 including his photographs of the spectra of the red stars and his spectroscopic proof of the meteoric constitution of ,saturn's rings1 demonstrated what he could accomplish at a small observatory unfavorably situated4 ,at ,mt4 ,hamilton he was able in the course of only two years to organize thoroughly the work of the ,observatory1 and to adapt the ,crossley reflector for his purpose1 taking photographs of the nebul that have never been equalled4 ,his discovery that most nebul have a spiral structure is of fundamental importance4 ,it is not easy to overestimate what might have been accomplished by ,keeler in the next twenty or thirty years1 both by his own researches and by his rare executive ability1 for it must be remembered that his genius as an investigator was rivaled by personal qualities which made his associates and acquaintances his friends4 99 99 99 99 99 ,henry ,sidgwick1 late ,knightbridge professor of moral philosophy at ,cambridge1 died on ,august #bh1 at the age of sixty-two years4 ,there are usually not many events to record in the life of a university professor1 but ,sidgwick had an opportunity to prove his character when he resigned a fellowship in ,trinity ,college because holding it implied the acceptance of certain theological dogmas4 ,liberalizing influences1 however1 were at work1 of which he himself was an important part1 and he was later elected honorary fellow of the same college1 and in #ahhc became professor of moral philosophy in the ,university4 ,sidgwick published three large works--#8,methods of ,ethics' 7#ahgd71 #8,principles of ,political ,economy' 7#ahhc7 and #8,elements of ,politics' 7#ahia7--;in addition to a great number of separate articles4 ,all these works1 especially the #8,ethics1' show an intellect to a rare degree both subtle and scientific4 ,there was a distinction and a personal quality in what he wrote that made each book or essay a work of art1 as well as a contribution to knowledge4 ,those who knew ,professor ,sidgwick--and the writer of the present note regards it as one of the fortunate circumstances of his life that he was for several years a student under him--realize that the qualities of the man were even more rare than those of the author4 ,his hesitating utterance1 always ending in exactly the right word1 but represented the caution and correctness of his thought4 ,subtlety1 sincerity1 kindliness and humor were as happily combined in his daily conversation as in his writings4 ,it is said that he was never #8entrapped into answering a question by yes or no1' but his deeds and his influence were positive without qualification or limitation4 99 99 99 99 99 ,friedrich ,wilhelm ,nietzsche1 who died on almost the same day as ,sidgwick1 was also a writer on ethics and once a university professor1 but the life and writings of the two men present a strange contrast4 ,where ,sidgwick's touch was light as an angel's1 ,nietzsche trampled like a bull2 the one was the embodiment of reason1 caution1 consideration and kindliness1 the other represented paradox1 recklessness1 violence and brute force4 ,still ,nietzsche deserves mention here1 as his ethical views1 based on the ,darwinian theory of the survival of the fit1 are not unlikely to be urged hereafter by saner men1 and to become an integral part of ethics when ethics becomes a science4 ,as a matter of fact1 after resigning his professorship at ,zurich1 and even while writing his remarkable books1 ,nietzsche suffered from brain disease1 and during the past eleven years his reason was completely lost4 ,,index4 ,,names ,,of ,,contributors ,,are ,,printed ,,in ,,small
