,,james ,,cutbush ,,james ,,cutbush ,,an ,,american ,,chemist #aghh-ahbc ,,by ,,edgar ,f4 ,,smith ,,provost ,,of ,,the ,,university ,,of ,,pennsylvania ,let us preserve the memory of the deserving2 perhaps it may prompt others likewise to deserve-- ,,philadelphia1 ,,pa4 #aiai ,,printed ,,by ,j4 ,b4 ,,lippincott ,,company ,,to ,,my ,,fellow-,,chemists ,,preface ,there is nothing thrilling in the following pages4 ,they contain the story of the life-work of a very modest man deeply interested in and enamoured with the science of chemistry1 who sought also to inspire others and to familiarize the general public of his time with the intimate connection of chemistry with manufactures and things which enter so largely into every-day occupations4 ,he was an active member of a small group of chemists who1 in the early years of eighteen hundred1 caused thousands of the laity to give thought to the possibilities of ,chemistry1 and in addition was a pioneer in pyrotechnics1 on which account he is deservedly entitled to every recognition4 ,more than a century has passed since his most serious efforts were put forth4 ,however1 it will not be long until that early galaxy of chemical enthusiasts of which he was a member will be accorded a high place in the history of the development of the science in ,america4 ,,james ,,cutbush ,,an ,,american ,,chemist #aghh-ahbc ,it is scarcely conceivable that anything pertaining to the development of chemical science in ,america would fail to interest its chemists4 ,the response to the needs of the ,nation in the last few years has shown how marvelously they wrought and the wonderful things which they brought to light4 ,yet in the long ago--in the days of which we only know by hearsay1 and through desultory reading1 there lived chemists with enthusiasm1 knowledge and initiative1 whose aim it was to have their chosen science contribute to the welfare of humanity4 ,in the labors of such men as ,james ,woodhouse1 ,robert ,hare1 ,adam ,seybert1 ,henry ,seybert1 ,john ,redman ,coxe1 ,joseph ,cloud1 ,gerard ,troost1 and many others1 the scientific spirit predominated1 although with it went the purpose1 more or less sharply defined1 of making their acquirements useful4 ,particularly noticeable was this in the instance of ,woodhouse4 ,the general consensus of opinion among present-day chemists is that chemistry should be helpful to all4 ,it may and should be scientific1 but its principles ought to be scientifically applied in every useful manner4 ,the reader1 desirous of learning the aims and ambitions of the fathers of the science in our country1 will profit by turning to the files of the ,aurora1 an old daily paper of ,philadelphia1 for the year #ahjh1 and beginning about the middle of ,july will there encounter a most interesting series of articles on the applications of chemistry under the general heading ,,application ,,of ,,chemistry ,,to ,,arts ,,and ,,manufactures ,there are fifteen separate papers4 ,in considering the period--#ahjh1--the age of the young ,republic1 and that the times were far from quiet2 that unrest and uncertainty prevailed as to the fate of the ,republic1 it does not surprise that thought should have been given to means of protection2 hence gunpowder was the very first product to engage the author of the series of articles4 ,the proving and analysis of the powder are discussed at length4 ,the methods appear very primitive in the light of present-day knowledge1 but one must not forget the period4 ,one hundred years hence the masterpieces of present-day chemists will perhaps provoke smiles upon the countenances of those who perchance read them4 ,in this pioneer contribution on gunpowder analysis the charcoal of the powder is often called oxid of carbon4 ,in referring to the separation of potassium and sodium it is recommended to precipitate out the first in the form of tartrate4 ,naturally1 nitre itself comes in for serious thought and the explosibility of the mixture of charcoal1 nitre and sulphur arrests the author's attention1 for he emphasizes the fact-- that1 independent of the formation of gases or airs1 the agency of caloric1 or matter of heat1 generated in the process of combustion1 considerably facilitates the strength of the powder1 in consequence of producing the expansion of these airs4 ,recently1 under the pressure of a national necessity1 which will not soon be forgotten1 the problem of getting nitre--nitrates and kindred bodies--had the earnest attention of chemists4 ,so1 in the period before and after #ahjh1 methods of forming nitre had grave consideration4 ,for instance1 this question1 now amusing1 was propounded-- ,how much nitre could be manufactured from the refuse animal and vegetable matter of the ,city of ,philadelphia in case of emergency8 ,what quantity could be prepared by elixating or washing the rubbish of old buildings1 the earth of stables1 cellars1 etc41 and the soil of certain tracts of the ,united ,states8 ,it is quite proper that mention should have also been made of the natural nitre beds1 as well as of the artificial beds built up from slow experience4 ,reference is made that in ,france nitre was won from the lime and rubbish of old1 ruinous buildings1 and from the floors of stables and pigeon houses1 while it is also recorded that during the ,american ,revolution1 the same means1 by the hand of economy and industry1 afforded quantities of this article in certain of the then ,colonies1 and that in the ,southern portions it was obtained from the earthen floors of tobacco houses4 ,the presentation of the earliest methods of getting nitre is extremely interesting1 extended and elaborate1 giving the reader a full view of pioneer conditions and endeavor4 ,the scheme of purification of nitre for gunpowder use is illuminating and attractive4 ,attention is directed to the saltpetre rock and caves of the western portion of our country4 ,the preparation of charcoal is discussed4 ,the adaptability of charcoal from various sources receives careful thought in connection with its use in gunpowder2 so1 too1 the sulphur used for this particular purpose1 and there is recommended as a source of this ingredient1 the common pyrites so abundant throughout the ,states4 ,among other topics1 of vital interest in these days1 discussed in the continuing articles1 is the manufacture of spirit from potatoes4 ,the method employed in ,germany is presented in detail after which it is said-- ,potato spirit of excellent quality has been made in this city 7,philadelphia74 ,it is found1 not only to be much cheaper than grain used entirely1 but to afford better flavoured liquor and other qualities which give it a decided preference4 ,fermentation1 yeast and baking receive mention4 ,brewing and the different kinds of beer are fully examined4 ,in those days adulteration was practiced1 for wormwood and quassia were found as substitutes4 ,the preparation of beer and ale for home consumption would very likely find little favor in the dry-bone spirit of the present1 much less would the refining of wines and other spirituous liquors of high alcohol content meet with approbation4 ,however1 such prohibitory questions as are now discussed did not vitally concern our forefathers1 so that it was most proper and praiseworthy to advise the public how1 through the instrumentality of chemistry1 many of the needed articles of life might be made in the highest degree of purity4 ,in many homes there existed miniature brewing plants4 ,at the other extreme1 among useful commodities1 were the manufacture of fish glue1 common glue1 gelatine1 albumen1 magnesia alba1 etc4 ,the several articles thus published in one of the most respected and influential papers of that early day--#ahjh--;had for their purpose the education of the general public in the application of a science to their use1 but there was also a desire to arouse a deep and steady interest in science in general1 which seems quite plain from a quotation from that remarkable address of ,dr4 ,john ,morgan--at one time ,physician-in-,chief of the ,american ,army4 ,the passage was-- ,oh6 let it never be said in this ,city or in this ,province1 so happy in its climate and in its soil1 where ,commerce has long flourished and plenty smiled1 that science1 the amiable daughter of liberty and sister of opulence1 droops her languid head1 or follows behind with a slow1 unequal pace4 ,doubtless deeply moved himself by this impassioned appeal1 the author of the ,aurora papers exclaimed-- ,i pronounce with confidence this shall never be the case4 ,every useful kind of learning shall here fix a favorite seat and shine forth in meredian splendour1 to accomplish which may every heart and every hand be united4 ,and then1 probably overpowered by an inner1 compelling force and conscious of the possibilities of his science in the cause of man and the undeveloped resources of our country1 quietly awaiting the oncoming alterations to be performed by applying chemistry1 he continues with like spirit-- ,if ever there was a time to bring the ,arts and ,manufactures to perfection in this ,country1 it is the present2 for the season is approaching1 when1 of necessity1 which is the mother of invention1 our internal resources1 and the application of them to our wants1 will advance a brilliant and glorious epoch in the annals of our ,country--second to none but the declaration of independence4 ,who is to establish the chain of manufactures--to convert the crude productions of ,nature into useful articles2 but you enlightened citizens1 men of science and improvement1 artists and manufacturers4 ,the laboratory of ,nature will be thrown open to you1 and to use the scriptural phrase1 ',ye shall know even as ye are known4' ,throughout the whole series of these papers there is manifest that noble patriotic spirit which shows itself in the last paragraph4 ,there exists also an intelligent and unselfish spirit1 so that as one finishes his reading there comes to mind a query as to the author who wrote thus in #ahjh--who was this early advocate of applied chemistry--this enthusiast in chemistry8 ,each article bears at its conclusion the initials ,j4,c41 which in several of the earlier articles are erroneously given as ,i4,c4 ,they throw no light on our curiosity and probably no one would ever have known whom ,j4,c4 represented had not the man himself in later life confessed that as a lad of twenty years he penned these papers4 ,they are exceedingly well composed4 ,they show a wide1 general knowledge and also great familiarity with the science of chemistry4 ,their young author was ,james ,cutbush4 ,when ,robert ,hare was twenty years of age he gave to the world one of the finest discoveries made by a chemist4 ,cutbush presented known chemical facts for the use and improvement of natural conditions4 ,might not the young men of these days1 surrounded by every sort of help1 make similar earnest and worthwhile contributions8 ,they surely can do this if they are imbued with the spirit of the forefathers--the ,american spirit in chemistry4 ,additional evidence of ,cutbush's chemical activity at this early age may be seen in a contribution to the ,philadelphia ,medical ,museum 7#ahjh7 upon mercury fulminate4 ,this interesting body he declared to be mercury oxalate and cited as his authority ,aikin's ,chemical and ,mineralogical ,dictionary4 ,he believed that its oxalic acid content was due to the action of nitric acid upon alcohol4 ,such being the case1 he argued that he saw no reason why the salt could not be prepared in a way by which no alcohol is employed4 ,accordingly1 he mixed intimately two parts of salt of sorrel and one part of red precipitate4 ,upon this mixture he poured sixteen parts of water1 and rubbed the solid mass intimately together4 ,in time the red-colored mass assumed an ash color1 when it was collected on a filter and dried4 ,in his own words-- ,on trying a part of this powder on an anvil with a hammer1 it exploded very violently1 the comparison of which to that prepared by ,howard's process was nearly equal4 ,while ,cutbush was in error1 relative to the true composition of the fulminate1 he at least gave to the scientific world a characteristic property of mercuric oxalate1 which does explode with considerable violence1 while at #ahj ,c4 it quickly breaks down with a mild explosive effect4 ,singularly enough1 he seems not to have abandoned the view that the interaction of alcohol and nitric acid give rise to oxalic acid4 ,while doing experimental work1 ,cutbush was active in the dissemination of science facts through the medium of his pen4 ,thus it was in this year 7#ahjh7 that he published the ,useful ,cabinet4 ,the surroundings of ,cutbush were congenial4 ,woodhouse was at the zenith of his career4 ,john ,redman ,coxe figured largely in ,philadelphia science circles4 ,the delightful and widely trained ,benjamin ,smith ,barton was a prime favorite with the younger men of science2 ,adam ,seybert was laying the foundations of mineralogical chemistry and ,gerard ,troost was soon to appear and give additional zest and impetus to chemical research4 ,to all these men ,cutbush was known and favorably known1 judging from his own allusions to them in his scattered writings4 ,of them all he seems to have entertained the strongest attachment to the celebrated ,barton and the talented ,coxe1 although he wrote of ,dr4 ,woodhouse as an experimenter unequalled4 ,it is strange1 however1 that his references to ,robert ,hare are few and meagre4 ,it is not easy to understand why this should be the case4 ,true1 there existed local prejudices and cliques in the closing decades of the #ahth ,century and the opening decades of the #aith ,century4 ,they are to be deplored1 but humanity is frail and perhaps it is wisest to pass them by1 yet so many things could be better understood if all the facts were laid bare4 ,frequent favorable mention was made by ,cutbush of ,john ,redman ,coxe1 hence probably the appearance of several of his contributions in the pages of the ,philadelphia ,medical ,museum1 edited at this particular time by ,coxe4 ,for example1 in #ahji1 ,cutbush published an article on the formation of ether in this journal1 and suggested that the product of the interaction of sulphuric acid and alcohol could be best purified by distilling it over manganese or lead dioxide and not over caustic potash as was customary4 ,he also dwelt on the production of ethylene in this process1 attributing its presence to the dehydrating action of sulphuric acid upon the alcohol4 ,momentarily1 he rejoiced over this observation1 believing it was new1 but promptly subsided when he discovered that ,fourcroy and ,vauquelin had long before made the same observations and given the same explanation4 ,two years later 7#ahaa71 in the same journal1 ,cutbush reported results gathered from experiments to determine the value of the hop to brewers4 ,he said much in regard to its essential oil in the preparation of malt liquor and repeated earlier personal observations upon the importance of chemistry in the brewing operations-- ,an art in which1 to the principles of chemistry1 many improvements have been made4 ,to our worthy and ingenious countryman1 ,mr4 ,hare1 much praise is due for various improvements in this art1 which1 we may add1 were in consequence of his correct principles in chemistry and natural philosophy4 ,here is one of the few references to ,robert ,hare made by ,cutbush4 ,it was when ,hare was devoting most of his time and mental energies to the development and improvement of his father's business4 ,he applied his scientific knowledge to it1 only in the end to have it fail through the conditions which came upon the country during the period of the ,war of #ahab4 ,one cannot easily forget the filial devotion of ,robert ,hare to his father in this particular business4 ,gladly would he have pursued pure science1 but he knew his duty and assumed it1 although unable to devote much time to science until #ahah4 ,but that story has been told4 ,another appreciation from ,cutbush which appears years later reads as follows3 ,the deflagrator of ,professor ,hare of ,philadelphia is an apparatus well calculated for many interesting experiments on galvanism4 ,to that gentleman we are indebted for the compound blowpipe1 which produces a very intense heat by the combustion of hydrogen in contact with oxygen gas4 ,notwithstanding ,professor ,clark of ,england has laid claim to the apparatus1 and the use of hydrogen gas in this way1 the merit of the discovery is due to our learned and ingenious countryman4 ,the next few years in the life of ,cutbush were most interesting4 ,he enjoyed mingling with his fellows1 and it is recorded that in #ahaj he became a member of ,lodge ,no4 #b1 ,free and ,accepted ,masons1 comprising in its membership ,general ,peter ,muhlenberg and many other distinguished ,philadelphians in various walks of life4 ,upon them he made an exceedingly favorable impression1 because in ,june of #ahaa1 ,cutbush was made presiding officer of his ,lodge and frequently thereafter he was invited to address his brethren upon some of the topics of the moment4 ,it is quite certain that he also availed himself in his dignified position to inculcate a knowledge of science1 and his favorite science chemistry in particular1 for on the pages of the ,freemason's ,magazine for #ahaa may be seen ,subjects and ,importance of ,chemistry--an article for laymen in which is plainly set forth how the science enters every walk of life4 ,in many respects it recalls the introductory chapter of ,parke's ,chemical ,catechism1 for it advises how chemistry removes the veil from the fabric of ,nature1 and makes us acquainted with all the phenomena which happen around us4 ,the offerings of ,cutbush were fitting and most timely4 ,they aroused the interest of his audience and induced many to enter upon scientific pursuits4 ,at one place he enlarged upon the wonderful medicinal properties of a chalybeate water near ,colestown1 ,n4 ,j41 giving its analysis and the healthful effect it seemed to produce on those who used it4 ,again1 in the ,december issue of the ,freemason's ,magazine 7#ahha71 he presented a most interesting1 readable and succinct historical sketch of our science which concludes as follows3 ,thus chemistry is become an entirely new science4 ,it is no longer confined to the laboratory of the arts3 it has extended its flights to the sublimest heights of philosophy1 and pursues paths formerly regarded as impenetrable mysteries4 ,placed forever in the elevated rank it now holds1 rich with all its new conquests1 it is become the science most adapted to the sublime speculations of philosophy1 the most useful in advancing all the operations of the arts1 and the most rational for scientific amusement4 ,exact in its process1 sure in its results1 varied in its operations1 without limits in its applications and its views1 severe and geometrical in its reasoning1 there is scarcely any human occupation which it does not enlighten1 and upon the perfection of which it may not have great influence4 ,it bestows great enjoyment to every class of individuals3 and who would not be ambitious of becoming acquainted with a science which enlightens almost every species of human knowledge8 ,imagine for a moment the effect of such an enthusiastic proclamation of the powers of chemistry on the readers of the ,magazine6 ,it would be and no doubt was contagious1 with the consequence that our science was called upon to aid infant industries4 ,cutbush was far-visioned and dreamed of the development of our ,country's national resources4 ,he had the spirit of ,woodhouse1 ,seybert and others1 who1 too1 were actuated for our ,country's welfare1 for its development physically and spiritually1 and how better could this be accomplished than through the medium of science1 and in large measure by chemical science8 ,in his historical resume ,cutbush mentions some of the philosophers who have 444 cultivated and enriched the new theory of chemistry with discoveries which will forever give immortality to their names1 we have to notice ,aikin1 ,babington1 ,bancroft1 ,beddoes1 ,blagdon1 ,cavendish1 ,chenevix1 ,crichton1 ,cruickshank1 ,davy1 ,lord ,dundonald1 ,lord ,dundas1 ,fordyce1 ,garnett1 ,hatchett1 ,henry1 ,higgins1 ,hope1 ,howard1 ,kirvan1 ,bishop of ,llandaff1 ,murray1 ,nicholson1 ,pearson1 ,tennant1 ,tilloch1 ,thompson1 ,wedgwood1 and ,wollaston2 and ,achard1 ,crell1 ,gilbert1 ,gren1 ,goetling1 ,humboldt1 ,hermbstadt1 ,klaproth1 ,lowitz1 ,richter1 ,scherer1 ,tromsdorff1 ,westrumb1 ,wiegleb1 ,bertholet1 ,chaptal1 ,fourcroy1 ,lagrange1 ,guiton1 ,van ,mons1 ,proust1 ,sequin1 ,vauquelin1 etc41 etc4 ,to the modern chemist these names probably represent little4 ,perhaps a few sound familiar1 but the majority are unknown to him4 ,for instance1 who would be apt to say much about the ,bishop of ,llandaff1 who wrote to ,henry1 author of one of the earliest and most delightful texts3 ,,cambridge1 ,oct4 #bh1 #aghg4 ,sir-- ,allow me to return you my thanks of the obliging manner in which you conveyed to me the kind notice1 which the ,literary and ,philosophical ,society were pleased to take of my essay2 and to assure you at the same time that it will give me great pleasure to be acquainted with a gentleman who is so eminently distinguished for his skill in chemistry1 as you have shewn yourself to be4 ,i have been told by good authority1 of an odd fact relative to calcined mercury1 the fact is this3 ,a bottle which contained some calcined mercury which had been purchased in ,london was left standing without its cork for near thirty years without being looked at4 ,when it was examined1 the greater part of it was revivified4 ,i have the honour to be1 ,sir1 ,yr obliged servt ,,bp4 ,,llandaff4 ,and this celebrated ,bishop was no less a personage than ,dr4 ,watson1 whose ,chemical ,essays are most charming1 instructive reading at the present moment4 ,students of the history of our science will find them to be so4 ,but all these early chemists--ancient1 if you please--are gone4 ,they cultivated chemistry with pleasure and ardor4 ,some left visible imprints1 while scarce a vestige remains of others4 ,their labours have made our path easier4 ,a century hence1 many honoured to-day and respected for their achievements1 will receive scant consideration1 though the work of the present looms up large in our judgment4 ,the founding of the ,columbian ,chemical ,society in #ahaa was an event in the chemical circles of ,philadelphia4 ,the old ,chemical ,society of ,philadelphia went out of existence in #ahji1 with the death of ,woodhouse4 ,the new organization was founded by a number of persons desirous of cultivating chemical science4 ,it comprised many young men zealous in research4 ,the names of eminent foreigners and distinguished ,americans are upon its rolls4 ,its meetings were monthly4 ,each year1 at the fall opening1 an oration on some chemical subject was delivered4 ,every month some member was appointed to read an original chemical essay4 ,it was recorded that any person desirous of membership 444 previous to his election 444 shall read an original essay on some chemical subject on which any member may speak not more than ten minutes4 ,this feature was held to be important2 at least the daily papers made note of it1 as is evident from the subjoined excerpt3 ,the following gentlemen have been elected ,junior members of the ,columbian ,chemical ,society1 during the last year1 after having read original dissertations1 the subjects of which are attached to their respective names3 ,mr4 ,t4 ,w4 ,robertson1 ',objections to the ,existence of a ,principle of ,repulsion4' ,mr4 ,francis ,brognard1 ',on ,chemical ,affinity4' ,mr4 ,lewis ,gerhardt1 ',on ,light4' ,mr4 ,dudley ,burwell1 ',on the ,chemical ,properties and ,medical ,uses of

,gignilliat1 ',on ,hydrogen ,gas4' ,mr4 ,john ,bent1 ',on ,oxygen ,gas4' ,the monthly meetings were announced in the city papers4 ,the announcements appeared at intervals through a period of years1 hence it may be assumed the ,society was an active organization and that its members regarded it as of consequence4 ,the personnel of its official family is not devoid of interest at present4 ,a single volume of memoirs1 printed in #ahac1 is still extant and may occasionally be seen2 from it will be learned that the ,hon4 ,thomas ,jefferson1 ,esq41 was the ,patron of the ,society and its ,president was ,james ,cutbush1 ,esq41 ,professor of ,natural ,philosophy1 ,chemistry and ,mineralogy in ,st4 ,john's ,college4 ,turning to the table of contents two contributions from the ,president are observed4 ,the first relates to the ,prognostic ,signs of the ,weather and the second is ,on the ,oxyacetite of ,iron as a ,test or ,reagent for the ,discovery of ,arsenic4 ,there is little chemistry in the first contribution1 and the second possesses value chiefly in the qualitative way4 ,they were evidently dashed off with the idea of arousing discussion1 in the hope that serious efforts might be set in operation in certain directions4 ,the thought which intrudes itself in looking through the ,memoirs1 noting the character of the individuals in the membership1 and upon recalling the chemical activities of ,cutbush1 is as to the man himself4 ,why should he1 barely twenty-three years of age1 be chosen to such an important and prominent station as that of ,president of the ,columbian ,chemical ,society8 ,what manner of man was he8 ,what his qualifications1 his fitness and his position in the science world of ,philadelphia8 ,a search through ancient volumes in many libraries failed to bring to light any facts bearing on these points4 ,the only fact discovered that had any value came from a newspaper advertisement bearing the date ,october1 #ahai4 ,it read3 ,bleaching ,liquor1 ,artificial ,musk1 ,phosphate of ,mercury and other chemical ,preparations1 prepared and sold by ,,james ,,cutbush ,chemist and ,apothecary ,no4 #be ,south ,fourth ,street1 ,phila4 where complete collections of chemical reagents are kept as usual4 ,here is a hint as to the occupation of ,cutbush4 ,he was a chemist--presumably a manufacturing chemist1 supplying the necessary reagents to persons desiring them for their chemical studies2 and further he was a pharmacist serving the various requirements of the medical men of the ,city4 ,thorough search through newspaper files disclosed that from the year #ahaa and perhaps two years earlier1 and extending up to the year #ahac--various announcements were made by ,cutbush as to lectures of a public nature4 ,these help us realize the character of the individual and his work4 ,for example-- ,dr4 ,cutbush's course of ,evening ,lectures on ,chemistry will commence early in the second week in ,november1 at the ,laboratory in ,videl's ,court1 in ,second1 near the ,corner of ,chestnut ,st4 and several months later the following notice was found-- ,,lectures on ,,theoretical ,,and ,,practical ,,pharmacy ,the subscriber1 at the solicitation of several medical gentlemen1 proposes to give a series of ,lectures on the ,theory and ,practice of ,pharmacy1 accompanied with the necessary chemical elucidations4 ,tickets may be had at #be ,south ,fourth ,st4 ,price #bj dollars4 ,,james ,,cutbush4 ,this was in the year #ahab4 ,early in #ahac1 a year after the preceding announcement1 there appeared-- ,j4 ,cutbush has the pleasure to announce to the ladies and gentlemen composing his class that the lectures on ,chemistry1 as well as those which are to follow on ,mineralogy and ,natural ,philosophy1 will be given in ,st4 ,john's ,lyceum in a building lately erected at the ,corner of ,chester and ,race1 between ,eighth and ,ninth ,sts4 ,n4,b4 ,the next lecture will be delivered this evening 7,saturday7 when1 at the request of several ladies1 the nitrous oxide or the exhilarating gas will be exhibited4 ,these announcements exhibit a phase in the development of chemical science which is worthy of pause and reflection4 ,science subjects had taken hold of many persons in the early years of the ,nineteenth ,century4 ,some of them became ardent enthusiasts and missioners in the extension of those subjects4 ,as early as #ahjh ,m4 ,godon gave lectures on ,mineralogy1 and in #ahaj announced a work of two volumes with a quarto supplement of charts4 ,the science of chemistry also had its advocates4 ,cutbush was evidently one of them1 although not the first4 ,this honor belongs to ,dr4 ,patrick ,kerr ,rogers1 father of ,william ,b4 ,rogers1 founder and first president of ,massachusetts ,institute of ,technology and ,president of the ,national ,academy of ,science1 of ,dr4 ,henry ,d4 ,rogers1 the eminent geologist1 and of ,james ,b4 and ,robert ,e4--both distinguished in the chemical field4 ,it was in #ahjb that ,patrick ,k4 ,rogers received his medical degree and embarked upon practice4 ,having spare time1 he began public lectures on the sciences1 confining himself from #ahjg to chemistry4 ,he was very successful4 ,one of his advertisements as it appeared in the ,aurora1 in #ahji1 read3 ,,evening ,,lectures ,,medical ,,and ,,chemical ,for ,gentlemen ,,dr4 ,p4 ,k4 ,,rogers ,having commenced a course of experimental lectures on ,chemistry to ladies1 proposes to give a similar course to gentlemen at a different hour4 ,twelve o'clock is the hour fixed for the former1 but as the gentlemen of the city are variously engaged in business during the day1 an evening hour will be more convenient for them4 ,the evening course is particularly intended to accommodate men who have a taste for scientific information and who cannot1 on account of their respective engagements during the day1 attend the lectures in the ,university4 ,a course for gentlemen will commence on ,tuesday and will terminate in the last week of ,february4 ,the hour will be seven o'clock in the evening4 ,two lectures at least1 sometimes three1 will be delivered every week4 ,about #aejj interesting experiments will be exhibited and submitted to the familiar inspection of the class4 ,several important experiments not hitherto introduced in any series of chemical demonstrations in this place will be displayed in the illustrations of different subjects4 ,the laboratory is in the lecturer's house in ,south ,ninth ,street1 opposite the ,university and is furnished with an excellent chemical apparatus4 ,the tickets for this course will be ten dollars4 ,the persons to take tickets will be entitled to the use of the lecturer's excellent medical and chemical library during the season4 ,persons wishing to attend this course will please call at the lecturer's home at any time before next ,tuesday in order to enter the names on the list4 ,ladies are informed that the list of subscribers to their course will not be closed until next ,monday at twelve o'clock at the hour the next lecture1 properly the first of the regular series1 will be delivered4 ,gentlemen are not admitted to these lectures4 ,in #ahaj ,dr4 ,rogers gave out a ,syllabus of #ab octavo pages ,on ,experimental ,lectures on ,natural ,philosophy and ,chemistry1 in which great emphasis was laid on the practical application of these sciences4 ,it also stated that it is even esteemed1 in some measure1 a cause of shame1 for persons of respectable education1 to be ignorant of their general principles4 ,in one newspaper announcement ,rogers said that in order to get sufficient space for his audience he had procured the use of the elegant and spacious ball room of ,m4 ,guillou4 ,in this special work he was repeating the labors of ,sir ,humphrey ,davy in ,london4 ,in reality1 ,rogers and his contemporaries and coadjutors were pioneer ,university ,extension ,lecturers4 ,they sought to popularize the natural and physical sciences and also broaden the vision or outlook of their hearers4 ,in the case of ,cutbush there was a strong desire to utilize chemistry in manufacture4 ,this he emphasized more strongly than any other lecturer4 ,another participant in the science propaganda was ,dr4 ,thomas ,p4 ,jones1 who devoted himself to ,chemistry4 ,the following notice of his lecture course is not devoid of interest3 ,on ,saturday1 the #acth inst41 at seven o'clock in the evening1 at ,dr4 ,jones' ,chemical ,lecture ,room1 ,s4,w4 ,corner of ,fourth and ,chestnut ,streets1 a lecture will be delivered on the properties of nitrous oxide1 or the exhilarating gas1 accompanied with a number of experiments4 ,a large quantity will be prepared to exhibit its effects when inhaled4 ,tickets at fifty cents each may be had at ,a4 ,finley's ,bookstore1 ,s4,e4 ,cor4 of ,chestnut and ,fourth ,streets1 or at the lecture room on the stated evening4 ,on perusing early chemical texts and advertisements1 such as those just given1 attention is pointedly called to nitrous oxide1 especially to its exhilarating properties1 for then it was laughing gas6 ,one ,philip ,h4 ,nicklin published a brochure entitled ,,the ,,only ,,genteel ,,way ,,of ,,getting ,,drunk ,a character representation of the effects produced by inhaling nitrous oxide gas4 ,the accuracy of which no man breathing can deny4 ,price #be cts4 ,to-day1 nitrous oxide means a benign ansthetic1 so helpful and merciful when one is brought under the knife of the skillful surgeon4 ,the honor accorded ,cutbush by his election to the ,presidency of the ,columbian ,chemical ,society was merited4 ,he was not only an active1 intelligent chemist1 devoted to the advancement of his science in all directions1 but he seems to have been an ardent enthusiast in the cause of education1 for on the #gth of ,november1 #ahaa1 he delivered an ,oration on ,education before the ,society for the ,promotion of a ,rational ,system of ,education4 ,his audience was large and consisted of the very best people of the city4 ,the printed oration shows that in addition to his chemical knowledge he was versed in the humanities1 in mathematics1 in philosophy and ancient history4 ,to-day the intelligent reader would pronounce the oration scholarly in every particular4 ,his chief purpose seems to have been to introduce into what was then the customary curriculum in schools a definite amount of science--natural and physical4 ,this is marked in the title of the organization before which he appeared on the occasion referred to1 in ,old ,st4 ,john's ,church4 ,the whole community was interested in education4 ,a society of educators had existed for a number of years4 ,neef had for a long time been advocating a system which was in reality a modification of the ,pestallozian ,system1 and men in every walk of life were seriously considering the innovations and advancements in this all-important subject4 ,little can be found in regard to the ,society for the ,promotion of a ,rational ,system of ,education1 but it may be inferred that the society had branches throughout the city and perhaps far beyond1 because elsewhere ,cutbush spoke of the society as under the ,presidency of ,john ,goodman1 ,esq41 and that its purpose was to bring about a reformation in education4 ,further1 ,goodman was a prominent layman in the ,church of ,old ,st4 ,john1 who with his associates1 ,messrs4 ,greiner and ,braeutigam1 fellow churchmen1 deeply impressed with the new thought1 seem to have established a school formed out of the ,lutheran congregation of the ,church of ,st4 ,john 444 instituted several professorships 444 one of which1 that of ,chemistry1 ,mineralogy and ,natural ,philosophy was conferred upon ,cutbush1 who proceeded to deliver courses on these subjects4 ,desirous of learning something in regard to ,st4 ,john's ,college1 the authorities of ,st4 ,john's ,lutheran ,church were consulted4 ,it must be remembered that this is the oldest ,english-speaking ,lutheran ,church in ,america4 ,it was founded by ,general ,peter ,gabriel ,muhlenberg1 and a unique distinction of this church is that in a period of #aac years it has had but three pastors4 ,nothing in the minutes of the church showed that a movement toward the establishment of a college had ever been made4 ,moreover1 search in the archives of the ,state ,department failed to bring to light the granting of a charter for an institution bearing the name of ,st4 ,john's ,college1 although in an old directory of ,philadelphia1 reference is made to ,st4 ,john's ,college1 and to the fact that ,cutbush was ,professor of ,chemistry1 ,mineralogy and ,natural ,philosophy in it4 ,the same source of information declared that the lectures were held back of ,st4 ,john's ,church in ,race ,street4 ,it may be questioned whether ,messrs4 ,goodman1 ,greiner and ,braeutigam1 who were the leaders of the congregation in the early years of #ahjj1 and enthusiasts in regard to the reformation in education1 did not1 perhaps1 carry out their thought without consulting the rest of their church associates4 ,in the history of the church there is a singular reference to the purchase of houses and lots which were known as the fourteen chimneys and the statement is made that the object of the purchase is not given4 ,these fourteen chimneys may have been the buildings back of ,st4 ,john's ,church on ,race ,street4 ,benjamin ,smith ,barton was another professor in ,st4 ,john's ,college1 who devoted himself to ,natural ,history and ,botany4 ,mr4 ,greiner1 who was associated with ,messrs4 ,goodman and ,braeutigam also taught in the institution1 and the head of the college or school was a ,mr4 ,bachman1 who later became a ,lutheran clergyman and naturalist of high repute in ,south ,carolina4 ,it is interesting at this far-away day to note the purposes of the ,society for the promotion of education as set forth in its constitution4 ,among other things1 it is said the education of youth in useful knowledge ought to be a primary object with parents and friends1 that more especially ought every endeavour to be made in a religious community to lay a sure and solid foundation for every moral and social virtue4 ,impressed with a conviction of this important truth1 a number of the members of ,st4 ,john's congregation1 willing to give every aid within their power toward the establishment and support of a ,rational ,system of ,education1 have formed themselves into a ,society for that purpose4 ,the copy of ,oration on ,education1 printed by ,cutbush1 which it was the privilege of the writer to peruse1 was the copy handed by ,cutbush ,to ,dr4 ,seybert with the compliments of the author4 ,in spite of age1 these words are very clear and legible1 and if the only relic by which to judge of the character of ,cutbush1 would indicate him to be a man of intelligence4 ,there were many other societies extant at this period and through subsequent years which had for their object the promotion of scientific education4 ,among these was the ,linnean ,society1 of which ,james ,cutbush was ,vice-,president4 ,cutbush had the honor of being one of the few of the original ,society of ,philadelphia for the ,promotion of ,national ,industry1 whose essays excited the attention of the citizens of the ,united ,states4 ,samuel ,jackson1 ,m4,d41 ,professor in the ,college of ,apothecaries1 was one of the most active members4 ,amidst all the activities of ,cutbush as a manufacturing chemist1 as a teacher of the science1 as a promoter of educational reforms1 as a member of many organizations1 he was very busy in a literary direction4 ,for example1 in #ahab he published a brochure on ,hydrostatics1 in which were described various hydrometers and their application4 ,numerous tables appear in it as well as many interesting and serviceable problems4 ,it was designed for and was helpful to artisans and to beginners in the science of physics and chemistry4 ,it is appropriately dedicated to the ,columbian ,chemical ,society4 ,in the year #ahac1 ,cutbush placed before the public his ,philosophy of ,experimental ,chemistry in two volumes4 ,it was dedicated to the ,professors and ,students of the ,university of ,pennsylvania and to the ,trustees of ,st4 ,john's ,college4 ,one cannot fail to wonder why ,cutbush should have so honoured the ,university when there is no record anywhere that he ever pursued studies under the gis of the ,university4 ,indeed1 it will probably remain a query as to where he was educated4 ,he is often spoken of as ,doctor ,cutbush and in at least two instances the title ,m4,d4 is placed after his name1 yet it is a fact that in no place where he personally was responsible for the printing of his name is there any title affixed to it4 ,every source of information from which it was hoped to ascertain where ,cutbush might have obtained the ,doctorate in the first decade of the #aith ,century failed to produce the fact4 ,libraries were searched and volumes that ordinarily convey such information were studied without positive result4 ,the little contribution on the ,philosophy of ,chemistry was favorably known1 for ,silliman1 in his reference to ,gorham's ,chemistry as the first book upon this subject by a native ,american1 credits ,cutbush with having written a similar work1 but speaks of the effort of ,cutbush as more elementary and not as exhaustive as that of ,gorham4 ,the introduction in the first volume of ,cutbush's work will always be interesting to ,american students of the science4 ,for example1 this quotation3 ,several original works have1 accordingly1 appeared1 and some editions of ,european treatises have been published with revisions1 corrections and additions by our countrymen4 ,the ,chemical and ,economical ,essays of ,pennington1 the edition of ,chaptal enlarged by the late ,james ,woodhouse 444 that of ,henry's ,chemistry by ,professor ,silliman of ,yale ,college1 with some others1 evince not only the learning and talents of our countrymen1 but a growing taste for the encouragement of learning and the acquisition of chemical knowledge4 ,besides these1 in the ,transactions of our ,societies and in the journals1 or periodical works1 several valuable papers have appeared4 ,the genius of the medical students of the ,university of ,pennsylvania1 in particular1 has been shown in a number of excellent inaugural dissertations1 some of which have added to the improvement of chemical science4 ,the first teacher of chemistry was ,dr4 ,benjamin ,rush 444 who may justly be styled the father of chemistry in ,america4 ,he commenced a course of lectures on this science in the then ,college of ,philadelphia2 and although chemistry at that day 7#agfh7 may be said to have been in its infancy1 yet the ,doctor did honour to the chair1 the school1 and his country4 ,we now speak of him only as a chemist4444 ,the advancement of chemistry in our city 444 is also indebted to other institutions4 ,the ,american ,philosophical ,society1 the ,college of ,physicians1 instituted in #aghg1 the ,medical ,society1 formed in #agga2 the ,chemical ,society under the patronage of ,doctors ,woodhouse and ,seybert1 which has since been dissolved2 the ,linnean ,society1 instituted under the presidency of the learned ,dr4 ,benjamin ,smith ,barton2 the ,columbian ,chemical ,society1 founded in #ahaa2 the ,academy of ,natural ,science--all show the zeal for useful knowledge and philosophical inquiry4444 ,for the introduction of popular chemistry1 the citizens of ,philadelphia are also indebted to ,doctors ,rogers and ,jones1 and to ,benjamin ,tucker1 who have taught ,chemistry with much zeal and talents4 ,many attractions are found in the ,philosophy of ,experimental ,chemistry4 ,the first discussion is that on ,chemical ,affinity4 ,two experiments are introduced4 ,in the first it is stated ,if equal parts1 by weight1 of sulphur and mercury be introduced into a crucible1 and in this situation exposed to a sufficient heat2 a compound will be formed1 called sulphuret of mercury4 ,in the second experiment the student is advised to ,mix together sulphur and potash1 and throw them into water2 the sulphur will separate4 ,if the same articles be put into a crucible and melted1 and then thrown into water1 the sulphur as well as the potash will be dissolved4 ,and next comes the ,rationale4 ,in the first experiment there is an instance of chemical action1 as well as of single affinity1 for the sulphur and mercury would remain separate if heat was not applied4 ,in consequence of this agent1 they unite into an uniform whole1 totally inseparable by mechanical means1 and possessing characters distinct from either of its constituent parts4 ,in the second experiment1 the union of sulphur with potash is effected by heat2 for if a sulphuret was not formed1 no solution of the sulphur would take place4 ,hence it is that chemical action is the consequence of a power1 without which it could never ensue1 and with which it always acts in unison4 ,this power is affinity4 ,then it is remarked3 ,chemistry is a science1 which has for its object to discover the constituent properties of bodies1 the result of the various combinations1 and the laws by which those combinations are effected4 ,its operations being either analytical or synthetical1 consist of composition1 or decomposition4 ,the laws which govern chemical changes have been resolved into those of attraction or affinity4 ,affinity of composition of chemical affinity differs from that of aggregation or cohesion or corpuscular attraction1 by acting upon matter of a different kind2 or by taking place between the ultimate constituent parts of bodies1 producing by its action1 substances possessing properties frequently very different1 and sometimes contrary to those of the constituent parts4 ,throughout the book the order of presentation is the experiment1 rationale1 and remarks4 ,a study of the ,philosophy shows clearly that ,cutbush presented his material in a rather original fashion4 ,his method is not observable in any of the text-books of that date4 ,in discussing potash1 ,cutbush wrote3 ,it has been supposed ever since our countryman1 ,dr4 ,woodhouse1 made an experiment with potash that this alkali had an inflammable base4 ,i am disposed to believe that the ,doctor was the first one who hazarded this conjecture as to the inflammable nature of potash when treated in certain ways4 ,the ,doctor found that a mixture of pearl ash with soot1 calcined by a very intense heat in a covered crucible1 when cold caught fire on the affusion of water4 ,the experiment was repeated with charcoal with the same result and the inflammation probably arose from the action of the base of the alkali on the water4 ,he says3 ,that ,thomas ,cooper 444 repeated this experiment1 and succeeded1 ,i think1 after several attempts1 in procuring the metal4 ,dr4 ,john ,redman ,coxe and myself also performed it1 but in our attempt we failed4 ,the professor1 however1 persevered1 and finally procured it4444 ,my brother1 ,dr4 ,edward ,cutbush1 succeeded in procuring it by using the heat of a black-smith's forge4 ,i have not heard of any other attempts in this country except by a gentleman in ,new ,york1 who was also successful4 ,these statements substantiate the idea that ,woodhouse isolated the metal potassium quite independently from any ,european chemist2 it even looks as if he may have isolated it in the manner referred to before ,sir ,humphrey ,davy had separated it with the aid of the electric current4 ,in the first volume of the ,philosophy there is a frontispiece1 a lamp furnace1 consisting of a brass rod1 fastened to a piece of metal1 furnished with rings of different diameters1 and thumb screws to raise or lower the lamp and rings when in use4 ,by this furnace evaporation1 digestion1 solution1 sublimation1 distillation and other processes1 which require a low temperature1 may be performed4 ,and in the second volume there is a frontispiece representing a portable universal furnace1 made of strong wrought iron plates and lined with bricks bedded in fire-proof loam4 ,the height of the furnace is two feet4 ,the body of the furnace is elliptical4 ,there are three openings in front of the furnace1 one above the other1 furnished with sliding doors1 and fitted with stoppers made of crucible ware4 ,both pieces of apparatus represent a marked advancement4 ,they were evidently exceedingly useful4 ,by their means it was possible to execute excellent work4 ,it would repay one to examine with care the various ,american text-books on chemistry1 beginning about #aggj and continuing down to #ahcj4 ,there would arise a picture before one's mind of the successive steps in the development of chemical apparatus1 and again1 the knowledge derived from the presentation of chemical theory and data would be refreshing and inspirational4 ,it is to be hoped that the time is not far distant when some library1 public or university library1 will go to the trouble of gathering the ,american texts on ,chemistry for the period just alluded to4 ,it is not likely that an alcove filled with this literature would be largely patronized1 yet it would be possible for the enthusiast on the development of chemistry in this country to collect from such a source a great deal of valuable material which might be presented with profit to the rising generation of ,american chemists4 ,cutbush had little leisure during the year #ahac1 as he was engaged with the duties of the ,college and was conducting popular lectures on an extended scale4 ,it was necessary for him to invite his friend1 ,dr4 ,george ,f4 ,lehman1 to assist in the various demonstrations4 ,they emphasized not only the theory but the practice of chemistry with its application to the useful arts4 ,their experiments were numerous and were of such a character as to appeal to the general public4 ,the course offered by ,professor ,cutbush and ,dr4 ,lehman was remunerative4 ,it is said the cost of tickets for ladies was #e4jj and those for gentlemen #h4jj4 ,in addition to the devotion of ,cutbush to these didactic courses in chemistry1 he spent much time in a literary way4 ,one of the best-known publishers of the city announced the purpose of printing the ,american ,artist's ,manual under the editorship of ,cutbush4 ,the advertisement stated-- ,to manufacturers1 however1 who are presumed to be interested in practical knowledge the value of such works is greatly diminished by the multiplicity of theories1 technical terms and complicated processes which they in general contain4 ,it is1 therefore1 unnecessary to expatiate on the advantages to be derived from such a publication as is now proposed in the present work4 ,while it is intended to embrace most of the ,arts and ,manufactures1 particular attention will be paid to those of agriculture1 brewing1 bleaching1 dyeing in its various branches1 the manufacture of glass1 pottery and all others which the situation of our country renders obviously of primary concern and importance4 ,this extensive and helpful publication appeared in #ahad in two octavo volumes of more than #fjj pages each4 ,the reader should note that ,the price to subscribers will be #g4jj in boards or #h4jj substantially bound1 payable on delivery4 ,those who procure subscriptions of nine copies and become accountable for their payment shall be entitled to one copy for their trouble4 ,the book was dedicated to ,benjamin ,smith ,barton4 ,no title of any kind appears after the author's name1 indicating that he had probably by the year #ahad severed his connection with all his educational projects in ,philadelphia4 ,in the preface the author speaks of ,having devoted the greater part of his life to chemical pursuits4 ,glancing through these volumes the impression made upon the reader was that the author had read widely in the sciences1 but particularly in his favorite science1 chemistry4 ,the book is really a popular dictionary of chemical technology4 ,while it is sparsely illustrated1 early forms of chemical glassware are pictured4 ,from these may be gathered the story of the gradual development of very useful apparatus1 for example1 such as is used in various kinds of distillation4 ,that ,cutbush had probably ceased his professional duties by the year #ahad1 as has just been hinted1 is further emphasized on noting that he was appointed ,assistant ,apothecary ,general in the ,u4 ,s4 ,army on the twelfth day of ,august in the year #ahad4 ,what his duties as such may have been has not been discovered4 ,it would not be fair to call it a radical change in position1 but it was a change which necessitated ,cutbush giving more thought and attention to pharmacy1 which in his earlier career was a secondary subject1 but in which he was so proficient that he attracted to himself the attention of leading men in medical circles4 ,he was in ,philadelphia1 prosecuting his duties as late as the year #ahai4 ,it is known that during this period he was attached to the ,northern ,division of the ,army4 ,in #ahbj ,dr4 ,james ,lovell1 ,surgeon ,general of the ,army1 suggested to ,general ,thayer1 ,superintendent of the ,military ,academy at ,west ,point1 that ,cutbush be appointed ,chief ,medical ,officer at the ,academy and ,post of ,west ,point4 ,in this capacity he served for seventeen months1 when he became ,acting ,professor of ,chemistry and ,mineralogy in the ,academy4 ,the first lecture in his new position was delivered ,october #i1 #ahbj4 ,in a sense1 it marked the beginning of a new career for ,cutbush4 ,he resumed teaching duties1 but gave himself more particularly to the study1 not only of gunpowder1 which never ceased to be interesting to him1 but to explosives of higher character1 and in this latter field he reached his greatest eminence and may confidently be regarded as a pioneer in it4 ,just before leaving ,philadelphia1 in the year #ahbj1 ,cutbush wrote ,benjamin ,silliman at some length on an improvement of the ,voltaic electrical lamp4 ,it was an ingenious modification and constituted the first contribution made by ,cutbush to the ,american ,journal of ,science4 ,but1 returning to his life at ,west ,point1 it may be observed that in #ahbb he contributed his second article to the ,journal of ,science1 which did not appear in print1 however1 until #ahbd4 ,this article related to the composition and properties of the ,chinese fire and the so-called brilliant fires4 ,it was very interesting4 ,it displayed a thorough and wide knowledge of pyrotechnics with which ,cutbush1 in previous years1 had been gradually familiarizing himself4 ,at one point he said3 ,most if not all the compositions used in fireworks1 including military fireworks1 were more the result of the labours of the artisan who was neither controlled by fixed principles nor by a knowledge of the effects and properties of bodies and of the systematic experiments of the chemist1 and yet in consequence of some fortuitous and repeated trials we find that he has been successful1 and moreover has amassed a body of facts which we may reasonably infer may either be rendered more perfect by knowledge or improved upon by the exact aid of chemical science4 ,here is every proof of his purpose to apply his understanding of chemical principles and his own experience to the solution of pyrotechnic problems1 for he continues3 ,pyrotechnics is at present considered under two heads1 namely1 fireworks for exhibition and military fireworks4 ,the latter is undoubtedly the most useful1 as it embraces a variety of propositions calculated for attack and defence both for naval and land service4 ,almost simultaneously there appeared in the same ,journal of ,arts and ,science another contribution by ,cutbush1 entitled ,,remarks ,,concerning ,,the ,,composition ,,and ,,properties ,,of ,,the ,,greek ,,fire ,in the light of recent events and the use of all sorts of chemical bodies for warfare and destruction it will not be uninteresting to introduce here a few paragraphs from this remarkable contribution4 ,he says3 ,the ,greek fire was invented by ,callinicus of ,heliopolis1 a town in ,syria1 who used it with so much skill and effect during a naval engagement that he destroyed a whole fleet of the enemy1 in which were embarked #cj1jjj men4 ,it appears that in the reign of ,louis ,,xv1 a chemist of ,grenoble1 ,dupre de ,mayen1 discovered a composition similar in effect to the ,greek fire of ,callinicus1 which was exhibited at ,brest1 and proved successful1 but the preparation was kept secret4 ,the original ,greek fire was used in #abia1 and also in #afgi4444 ,writers have defined it to be a sort of artificial fire1 which burns with increased violence when it mixes with water4444 ,that it was a liquid composition1 we may infer from the modes of using it1 which were several4 ,it was employed chiefly on board of ships1 and thrown on the vessels of the enemy by large engines4 ,it was sometimes kindled in particular vessels1 which might be called fire ships1 and which were introduced among a hostile fleet4 ,sometimes it was put into jars and other vessels1 and thrown at the enemy by means of projectile machines1 and sometimes it was squirted by soldiers from hand engines1 or blown through pipes4 ,this fire was also discharged from the foreparts of ships by a machine constructed of copper and iron1 the extremity of which is said to have resembled the open mouth and jaws of a lion or other animal4 ,they were painted1 and even gilded1 and were capable of projecting the liquid fire to a great distance4 444 ,john ,cameniata1 speaking of his native city1 ,thessalonica1 which was taken by the ,saracens in the year #ijd1 says that the enemy threw fire into the wooden works of the besieged1 which was blown into them by means of tubes1 and thrown from other vessels4444 ,this proves that the ,greeks1 in the beginning of the ,tenth ,century1 were no longer the only people acquainted with the art of preparing this fire1 the precursor of our gunpowder4 ,the ,emperor ,leo1 who about the same period wrote his ,art of ,war1 recommends such engines1 with a metal covering1 to be constructed in the foreparts of ships1 and he twice afterwards mentions engines for throwing out ,greek fire4444 ,for many centuries the method of making this dreadful article of destruction was lost2 but it has just been discovered by the librarian of the elector of ,bavaria1 who has found a very old ,latin manuscript which contains directions for preparing it4 444 ,on the subject of incendiary and other military fireworks1 the ,french have certainly laid the foundation for the very preparations now used by the ,british1 for the formul for such preparations may be traced to the ,french service4444 ,the ,moors were in possession of the secret for preparing the ,greek fire in #adcb1 according to the testimony of ,brocquire4 ,bertrandon de la ,brocquire was in ,palestine in #adcb as counsellor to the ,duke of ,burgundy4 ,he was present at ,barrat during one of the ,moorish celebrations4 ',it began1' he remarks1 'in the evening at sunset4 ,numerous companies scattered here and there were singing1 and uttering loud cries4 ,while this was passing1 the cannon of the castle was fired1 and the people of the town launched into the air bein haut et bein loin1 une maniere de fue plus gros fellot que je veisse oncques allume4 ,they told me they made use of such at sea1 to set fire to the sails of an enemy's vessel4 ,it seems to me that it is a thing easy to be made1 and at a little expense it may be equally well employed to burn a camp or a thatched village1 or in an engagement with cavalry to frighten their horses4 ,curious to know its composition1 ,i sent the servant of my host to the person who made this fire1 and requested him to teach me his method4 ,he returned for answer1 that he dare not1 for that he should run great danger were it known2 but there is nothing a man will not do for money4 ,i offered him a ducat1 which quieted his fears1 and he taught me all he knew1 and even gave me the moulds in wood1 with the other ingredients1 which ,i have brought to ,france4' 444 ,when ,constantinople was attacked1 the ,emperor ,leo burnt the vessels or boats1 to the number of one thousand eight hundred1 by means of the ,greek fire4444 ,its composition was kept secret at ,constantinople1 pretending that the knowledge of it came from an angel to the first and greatest of the ,constantines1 with a sacred injunction not to divulge it under any pretext1 etc4 ,it 444 was kept secret above #djj years 444 was stolen by the ,mahometans1 who employed it against the ,crusaders4 ,a knight1 it appears1 who despised the swords and lances of the ,saracens1 relates1 with heartfelt sincerity1 his own fears at the sight and sound of the mischievous engine that discharged a torrent of fire4 ',it came flying through the air1 like a winged1 long-tailed dragon1 about the thickness of a hogshead1 with a report of thunder1 and the velocity of lightning2 and the darkness of the night was dispelled by this deadly illumination4 ,the use of the ,greek1 or as it might now be called the ,saracen fire1 was continued to the middle of the ,fourteenth ,century1 when the scientific or casual compound of nitre1 sulphur and charcoal effected a new revolution in the art of war1 and the history of mankind4' 444 ,we do not know of any imitation of the original ,greek fire having been used in modern warfare1 but have no hesitation in believing that naphtha prepared as already stated would in many cases prove advantageous4 ,it seems to be well calculated for close naval combat1 if the object be to destroy the sails and rigging of an enemy's ship4 ,the rapidity and extent of its combustion1 added to the circumstances of its peculiar properties1 that of resisting the action of water in particular1 contribute altogether to this opinion4 ,the entire article from which these excerpts have been made is worthy of study1 even at this late date4 ,it is suggestive and carries with it many historical references of value4 ,the enthusiasm of ,cutbush for pyrotechnic bodies is manifest in every line of this publication4 ,about a year later 7#ahbc7 ,cutbush discussed the formation of cyanogen in processes not previously noticed4 ,he spoke of the appearance of this gas in the putrefaction of animal and vegetable matter1 making the following remarkable and in some respects startling statement3 ,i believe it would be found that the compound 7carburet of azote7 is the basis of the miasmata which produces malignant1 bilious diseases4444 ,marsh miasmata are generally the cause of intermittent fevers4 ,now under particular circumstances of action may we not admit the generation of carburet of azote or cyanogen1 and if so1 as it readily unites with hydrogen1 may it not be the miasma which produces malignant bilious fevers1 since it is known that hydrocyanic acid is destructive to animal life and a most virulent poison8444 ,miasmata of some kind are the cause of yellow fever4 ,for our part we believe it to be carburet of azote1 or of some of its combinations1 and of these that with hydrogen1 from its deleterious character1 seems to be the one4 ,another observation made in this connection was that cyanogen is produced when charcoal is heated with nitric acid4 ,cutbush stated that he placed charcoal and nitric acid together in a retort and subjected them to distillation1 collecting the product in ,woulfe's bottles1 after which the resulting solutions were impregnated with potash1 and common sulphate and persulphate of iron introduced4 ,the colour instantly changed and became more or less blue1 proving the existence of the perferrocyanite of iron and1 consequently1 of cyanogen4 ,having never met this method of preparing cyanogen1 experiments were made in the writer's laboratory to verify the statement4 ,a blue1 or what had the semblance of a blue color1 could be obtained at the point given by ,cutbush1 but just as soon as the solution was acidulated1 as is always done1 the precipitate disappeared and there was not the slightest indication that ,prussian blue had been formed4 ,even after hours of rest there was not a sign of it4 ,association on the part of ,cutbush with the men of science in ,philadelphia during the first decade of the ,nineteenth ,century led to an extension of his interest in science circles1 so that during leisure moments at ,west ,point 7#ahbd7 he wrote of the following minerals observed by him in and near that place3 ,molybdenite1 kaolin1 tremolite1 schorl1 adularia1 garnet1 actinolite1 precious serpentine 7remarkably elegant71 epidote and diallage4 ,recently1 attention has been called to a volume by ,cutbush entitled ,lectures on the ,adulteration of ,food and ,culinary ,poisons4444 ,with a ,means of ,discovering ,them and ,rules for ,determining the ,purity of ,substances4 ,it was published at ,newburgh1 ,n4 ,y41 in #ahbc4 ,the writer has never seen this volume4 ,his search for it has been unsuccessful4 ,another publication was ,a ,synopsis of ,chemistry1 ,arranged ,alphabetically1 ,comprehending the ,names1 ,synonyms1 and ,definitions in that ,science4 ,new ,york3 ,e4 ,lewis1 #ahba4 ,this book is also exceedingly rare4 ,the real magnum opus of ,cutbush resulted in ,a ,system of ,pyrotechny 7#ahbe71 which voluminous publication did not appear until after his decease1 and then largely through the efforts of his wife and former students in the ,cadet ,corps1 for1 in ,silliman's ,journal1 this note appeared3 ,mrs4 ,cutbush1 widow of the late ,dr4 ,cutbush1 of ,west ,point1 proposes to publish by subscription a ,treatise on ,pyrotechny by her husband1 ,dr4 ,james ,cutbush4444 ,by the reputation which ,dr4 ,cutbush sustained1 as well as by the ability which his elaborate treatises on these subjects already published in this journal display1 there can be no doubt that this posthumous work will be worthy of the public patronage1 which we hope will be liberally bestowed4 ,even to-day this publication stands out preminently and for years has been referred to by artisans and by scientists4 ,chapters dealing with military fireworks have been seriously studied4 ,in the light of the violent fires1 grenades1 etc41 used in the late war the writings of ,cutbush become very fascinating4 ,they show that he truly blazed the way in this field4 ,in the introduction to this splendid volume he wrote3 ,on this head1 that of the application of chemistry to pyrotechny1 we claim so much originality1 as1 so far as we know1 to have been the first1 who applied the principles of chemistry4444 ,as this subject1 however interesting to the theoretical pyrotechnist1 cannot be understood without a knowledge of chemistry1 it is obvious that that science is a powerful aid to pyrotechny4444 ,viewing pyrotechny either as a science or an art1 there is undoubtedly required in its prosecution much skill and practice4 ,the mere artificer or fireworker by constant habit may understand1 it is true1 how to mix minerals1 prepare composition1 charge cases1 etc41 444 but without a knowledge of chemistry he cannot understand the theory4444 ,indeed1 chemistry is indispensable to pyrotechny4 ,much time and thought were given by ,cutbush in the experimental development of this particular subject in his own laboratory4 ,in reading upon the subject he had collected a vast material which was then put to crucial experimental tests4 ,these1 outside of his teaching hours1 occupied his whole attention4 ,an outline of how the work in the chemical department of the ,united ,states ,military ,academy was conducted will not be devoid of interest4 ,first ,year ,theory and ,experimental ,chemistry4 ,second ,year ,application of ,chemistry to the ,arts1 ,manufactures and ,domestic ,economy1 constituting along with ,mineralogy the second course4 ,pyrotechny naturally was developed quite extensively4 ,teachers of chemistry will note with pleasure the questions which ,cutbush arranged for his student corps1 particularly those questions which had to do with pyrotechny3 ,what is saltpetre8 ,what is nitric acid8 ,what are the sources of saltpetre1 and how it is obtained8 ,how is it formed in nitre beds1 extracted1 and refined8 ,what circumstances are necessary to produce nitre1 and how does animal matter act in its production8 ,what is the difference between the old and new process for refining saltpetre8 ,what reagents are used to discover the presence of foreign substances in nitre8 ,what are nitre caves8 ,where do they exist8 ,what are the nitre caves of the western country1 and how is nitre extracted from the earth8 ,what proportion of nitre does the saltpetre of the nitrate caves afford8 ,what is the theory of the process for extracting saltpetre from nitrous earth1 or nitrate of lime8 ,what is sulphur8 ,how is it obtained1 and how is it purified for the manufacture of gunpowder8 ,of what use is sulphur in the composition of gunpowder8 ,does it add to the effective force of gunpowder8 ,what is charcoal8 ,what is the best mode of carbonizing wood for the purpose of gunpowder8 ,what woods are preferred for this purpose8 ,in the charring of wood1 what part is converted into coal1 and what gas and acid are disengaged8 ,what is the use of charcoal in gunpowder8 ,what is gunpowder8 ,what are considered the best proportions for forming it1 and what constitutes the difference between powder for war1 for gunning1 and for mining8 ,how does the combustion of gunpowder take place8 ,can you explain why combustion takes place without the presence of a gaseous supporter of combustion1 as gunpowder will inflame in vacuo8 ,what are the products of the combustion of gunpowder8 ,what gases are generated8 ,to what is the force of fired gunpowder owing8 ,what are the experiments of ,mr4 ,robins on the force of gunpowder8 ,how would you separate the component parts of gunpowder so as to determine their proportions8 ,what are gunpowder proofs8 ,what is understood by the comparative force of gunpowder8 ,what are eprouvettes1 etc48 ,in noticing in the same manner the preparations used for fireworks1 and for war1 as the rocket1 for instance1 the following questions were propounded2 viz41 ,what is a rocket8 ,how is it formed8 ,is the case always made of paper8 ,what is the war rocket8 ,what is the composition for rockets1 and how does it act8 ,what particular care is required in charging a rocket8 ,what is the cause of the ascension of rockets8 ,what is the use of the conical cavity1 made in a rocket at the time it is charged1 or bored out after it is charged8 ,how do cases charged with composition impart motion to wheels1 and other pieces of fireworks8 ,what is understood by the rocket principle8 ,what is the rocket stick and its use8 ,is the centre of gravity fixed1 or is it shifting in the flight of rockets8 ,how are rockets discharged8 ,what is the head of a rocket8 ,what is usually put in the head8 ,are all rockets furnished with a head8 ,what is understood by the furniture of a rocket8 ,how are the serpents1 stars1 fire-rain1 etc41 forming the furniture of a rocket1 discharged into the air1 when the rocket has terminated its flight1 or arrived at its maximum of ascension8 ,what forms the difference between a balloon1 in fireworks1 and a rocket8 ,as the balloon contains also furniture1 and is projected vertically from a mortar1 how is fire communicated to it1 so as to burst it in the air8 ,is the fuse used1 in this case1 the same as that for bombs1 howitzers1 and grenades8 ,what is the ,asiatic rocket8 ,the fougette of the ,french8 ,in what siege were they employed with success by the native troops of ,india8 ,what was the nature of their war-rocket8 ,what is the murdering rocket of the ,french8 ,is the conical head hollow1 solid1 blunt1 or pointed8 ,why is it called the murdering rocket8 ,what is the ,congreve rocket8 ,is ,congreve the inventor or improver of this rocket8 ,what are ,congreve rockets loaded or armed with8 ,in what part is the load placed8 ,is the case made up of paper or sheet-iron8 ,what are the sizes of ,congreve rockets8 ,in the introduction to ,pyrotechnics ,cutbush remarked that he had consulted many authorities without much advantage1 finding the ,french the most helpful4 ,of the ,english he said3 ,as respects the turtle torpedo and catamarin submarine machines1 it appears that ,bushnel claims the originality of the discovery from the date of his invention1 although similar contrivances had long ago been suggested4 ,fulton's improvements1 in the torpedo1 are deserving of particular attention1 but it is plain that the ,catamarin of the ,english is the same in principle and application as ,fulton's torpedo and that ,fulton deserves the merit of it4 ,the ,system of ,pyrotechny bears the ear-marks of much careful experimental study4 ,it is a most worthy contribution1 and is strong proof of the dominating force in the mind of ,cutbush1 namely1 to make his science as widely useful as possible4 ,chemists may justly take pride in this early contribution in the application of chemical principles4 ,the life story of ,cutbush has now been told4 ,it is really the story of his life activities1 for regrettable as it is1 there does lack a picture of the man's personality4 ,the parents of ,james ,cutbush were ,edward ,cutbush and ,anne ,marriat4 ,the father was a stone-cutter or carver4 ,to these good people were given four children3 ,edward1 born in #aggb2 ,ann1 in #aghb 7who died in #agih72 ,william1 born in #aghe1 and ,james in #aghh4 ,edward became prominent as a naval surgeon1 while ,william graduated from ,west ,point in #ahab1 and attained eminence as an engineer4 ,indeed1 at an early age1 ,william was a midshipman in the ,united ,states ,navy1 and was taken prisoner by the ,algerines at the time the frigate ,philadelphia ran aground in the harbor of ,tripoli1 from which he was released after two years' confinement in prison1 and returned to the ,united ,states1 when he became a cadet in the ,military ,academy4 ,james ,cutbush must have been a man of mark among his neighbors--as indicated by sundry positions of trust which he held4 ,further1 he must have been a favorite with the ,cadet ,corps at ,west ,point1 where he was buried4 ,his tomb there bears this inscription3 ,sacred to the memory of ,dr4 ,james ,cutbush1 ,member of the ,american ,philosophical ,society1 ,late ,surgeon1 ,u4 ,s4 ,army and ,professor of ,chemistry at the ,u4 ,s4 ,military ,academy1 ,west ,point1 ,n4 ,y41 who departed this life ,december #ae1 #ahbc1 aged #ce years4 ,an honourable tribute of respect from his grateful pupils4 ,the work of ,cutbush was of the genuine pioneer character1 and enriched the annals of ,american chemistry4 ,while it would be delightful to know more of the man1 cruel fate compels us to be content with the estimate1 brief though it is1 given in ,poulsen's ,american ,daily ,advertiser1 ,december #bc1 #ahbc3 ,a man not only known for his extensive knowledge of chemistry1 but distinguished for his philosophy and patriotism4 99 99 99 99
