It is scarcely conceivable that anything pertaining to the development of chemical science in America would fail to interest its chemists. 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 light. Yet in the long ago—in the days of which we only know by hearsay, and through desultory reading, there lived chemists with enthusiasm, knowledge and initiative, whose aim it was to have their chosen science contribute to the welfare of humanity. In the labors of such men as James Woodhouse, Robert Hare, The general consensus of opinion among present-day chemists is that chemistry should be helpful to all. It may and should be scientific, but its principles ought to be scientifically applied in every useful manner. The reader, desirous of learning the aims and ambitions of the fathers of the science in our country, will profit by turning to the files of the Aurora, an old daily paper of Philadelphia, for the year 1808, and beginning about the middle of July will there encounter a most interesting series of articles on the APPLICATION OF CHEMISTRY TO ARTS AND MANUFACTURES There are fifteen separate papers. In considering the period—1808,—the age of the young Republic, and that the times were far from quiet; that unrest and uncertainty prevailed as to the fate of the Republic, it does not surprise that thought should have been given to means of protection; hence gunpowder was the very first product to engage the author of the series of articles. The proving and analysis of the powder are discussed at length. The methods appear very primitive in the light of present-day knowledge, but one must not forget the period. One hundred years hence the masterpieces of present-day chemists will perhaps provoke "that, independent of the formation of gases or airs, the agency of caloric, or matter of heat, generated in the process of combustion, considerably facilitates the strength of the powder, in consequence of producing the expansion of these airs." Recently, under the pressure of a "How much nitre could be manufactured from the refuse animal and vegetable matter of the City of Philadelphia in case of emergency? What quantity could be prepared by elixating or washing the rubbish of old buildings, the earth of stables, cellars, etc., and the soil of certain tracts of the United States?" It is quite proper that mention should have also been made of the natural nitre beds, as well as of the artificial beds built up from slow experience. "same means, by the hand of economy and industry, afforded quantities of this article in certain of the then Colonies, and" that in the Southern portions it was obtained from the earthen floors of tobacco houses. The presentation of the earliest methods of getting nitre is extremely interesting, extended and elaborate, giving the reader a full view of pioneer conditions and endeavor. The scheme of purification of nitre for gunpowder use is illuminating and attractive. Attention is directed to the saltpetre rock The preparation of charcoal is discussed. The adaptability of charcoal from various sources receives careful thought in connection with its use in gunpowder; so, too, the sulphur used for this particular purpose, and there is recommended as a source of this ingredient, the common pyrites so abundant throughout the States. Among other topics, of vital interest in these days, discussed in the continuing articles, is the manufacture of spirit from potatoes. 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 (Philadelphia). It is found, not only to be much cheaper than grain used entirely, Fermentation, yeast and baking receive mention. Brewing and the different kinds of beer are fully examined. In those days adulteration was practiced, for wormwood and quassia were found as substitutes. The preparation of beer and ale for home consumption would very likely find little favor in the "dry-bone" spirit of the present, much less would the refining of wines and other spirituous liquors of high alcohol content meet with approbation. However, such prohibitory questions as are now discussed did not vitally concern our forefathers, so that it was most proper and praiseworthy to advise the public how, through the instrumentality of chemistry, many of the needed articles At the other extreme, among useful commodities, were the manufacture of fish glue, common glue, gelatine, albumen, magnesia alba, etc. The several articles thus published in one of the most respected and influential papers of that early day—1808—had for their purpose the education of the general public in the application of a science to their use, but there was also a desire to arouse a deep and steady interest in science in general, which seems quite plain from a quotation from that remarkable address of Dr. John Morgan—at one time Physician-in-Chief of the American Army. The passage was— "Oh! let it never be said in this City or in this Province, so happy in its climate Doubtless deeply moved himself by this impassioned appeal, the author of the Aurora papers exclaimed— "I pronounce with confidence this shall never be the case. Every useful kind of learning shall here fix a favorite seat and shine forth in meredian splendour, to accomplish which may every heart and every hand be united." And then, probably overpowered by an inner, compelling force and conscious of the possibilities of his science in the cause of man and the undeveloped resources "If ever there was a time to bring the Arts and Manufactures to perfection in this Country, it is the present; for the season is approaching, when, of necessity, which is the mother of invention, our internal resources, and the application of them to our wants, will advance a brilliant and glorious epoch in the annals of our Country—second to none but the declaration of independence. Who is to establish the chain of manufactures—to convert the crude productions of Nature into useful articles; but you enlightened citizens, men of science and improvement, artists and manufacturers. The laboratory of Nature will be thrown open to you, and Throughout the whole series of these papers there is manifest that noble patriotic spirit which shows itself in the last paragraph. There exists also an intelligent and unselfish spirit, so that as one finishes his reading there comes to mind a query as to the author who wrote thus in 1808—who was this early advocate of applied chemistry—this enthusiast in chemistry? Each article bears at its conclusion the initials J.C., which in several of the earlier articles are erroneously given as I.C. They throw no light on our curiosity and probably no one would ever have known whom J.C. represented had not the man himself in later life confessed that as a lad of twenty years he penned these papers. They are exceedingly When Robert Hare was twenty years of age he gave to the world one of the finest discoveries made by a chemist. Cutbush presented known chemical facts for the use and improvement of natural conditions. Might not the young men of these days, surrounded by every sort of help, make similar earnest and worthwhile contributions? They surely can do this if they are imbued with the spirit of the forefathers—the American spirit in chemistry. Additional evidence of Cutbush's chemical activity at this early age may be seen in a contribution to the Philadelphia Medical Museum (1808) upon mercury fulminate. This interesting body he declared to be mercury oxalate "On trying a part of this powder on an anvil with a hammer, it exploded very violently, the comparison of which to that prepared by Howard's process was nearly equal." While Cutbush was in error, relative to the true composition of the fulminate, he at least gave to the scientific world a characteristic property of mercuric oxalate, which does explode with considerable violence, while at 180° C. it quickly breaks down with a mild explosive effect. Singularly enough, he seems not to have abandoned the view that the interaction of alcohol and nitric acid give rise to oxalic acid. While doing experimental work, Cutbush was active in the dissemination of science facts through the medium of his pen. Thus it was in this year (1808) that he published the "Useful Cabinet." The surroundings of Cutbush were congenial. Woodhouse was at the zenith of his career. John Redman Coxe figured largely in Philadelphia science circles. The delightful and widely trained Benjamin Smith Barton was a "An art in which, to the principles of chemistry, many improvements have been made. To our worthy and ingenious countryman, Mr. Hare, much praise is due for various improvements in this art, which, we may add, were in consequence of his correct principles in chemistry and natural philosophy." Here is one of the few references to Robert Hare made by Cutbush. It was when Hare was devoting most of his time and mental energies to the development and improvement of his father's business. He applied his scientific knowledge to it, only in the end to have it fail through the conditions which came upon the country during the period of the War of 1812. One cannot easily forget the filial devotion of Robert Hare to his father in this particular business. Gladly would he have pursued pure science, but he knew his duty and assumed it, although unable to devote much time to science until 1818. But that story has been told. Another appreciation from Cutbush which appears years later reads as follows: "The deflagrator of Professor Hare of Philadelphia is an apparatus well The next few years in the life of Cutbush were most interesting. He enjoyed mingling with his fellows, and it is recorded that in 1810 he became a member of Lodge No. 2, Free and Accepted Masons, comprising in its membership General Peter Muhlenberg and many other distinguished Philadelphians in various walks of life. Upon them he made an exceedingly favorable impression, "removes the veil from the fabric of Nature, and makes us acquainted with all the phenomena which happen around us." The offerings of Cutbush were fitting and most timely. They aroused the interest of his audience and induced many to enter upon scientific pursuits. At one place he enlarged upon the wonderful medicinal properties of a chalybeate water near Colestown, N. J., giving its analysis and the healthful effect it seemed to produce on those who used it. Again, in the December issue of the Freemason's Magazine (1881), he presented a most interesting, readable and succinct historical sketch of our science which concludes as follows: "Thus chemistry is become an entirely new science. It is no longer confined to the laboratory of the arts: it has extended its flights to the sublimest heights of philosophy, and pursues paths formerly regarded as impenetrable mysteries. Placed forever in the elevated Imagine for a moment the effect of such an enthusiastic proclamation of In his historical resume Cutbush mentions some "of the philosophers who have ... cultivated and enriched the new theory of chemistry with discoveries which will forever give immortality to their To the modern chemist these names probably represent little. Perhaps a few sound familiar, but the majority are unknown to him. For instance, who would be apt to say much about the Cambridge, Oct. 28, 1787." "Sir— "Allow me to return you my thanks of the obliging manner in which you conveyed to me the kind notice, which the Literary and Philosophical Society were pleased to take of my essay; 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 chemistry, as you have shewn yourself to be. I have been told by good authority, of an odd fact relative to calcined mercury, the fact is this: 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 at. When it "I have the honour to be, Sir, "Yr obliged servt And this celebrated Bishop was no less a personage than Dr. Watson, whose "Chemical Essays" are most charming, instructive reading at the present moment. Students of the history of our science will find them to be so. But all these early chemists—ancient, if you please—are gone. They cultivated chemistry with pleasure and ardor. Some left visible imprints, while scarce a vestige remains of others. Their labours have made our path easier. A century hence, many honoured to-day and respected for their achievements, will receive scant consideration, though The founding of the Columbian Chemical Society in 1811 was an event in the chemical circles of Philadelphia. The old Chemical Society of Philadelphia went out of existence in 1809, with the death of Woodhouse. The new organization was founded "by a number of persons desirous of cultivating chemical science." It comprised many young men zealous in research. The names of eminent foreigners and distinguished Americans are upon its rolls. Its meetings were monthly. Each year, at the fall opening, "an oration on some chemical subject" was delivered. Every month some member was appointed to read "an original chemical essay." It was recorded that "any person desirous of membership ... previous to his election ... This feature was held to be important; at least the daily papers made note of it, as is evident from the subjoined excerpt: "The following gentlemen have been elected Junior members of the Columbian Chemical Society, during the last year, after having read original dissertations, the subjects of which are attached to their respective names: "Mr. T. W. Robertson, 'Objections to the Existence of a Principle of Repulsion.' "Mr. Francis Brognard, 'On Chemical Affinity.' "Mr. Lewis Gerhardt, 'On Light.' "Mr. Dudley Burwell, 'On the Chemical Properties and Medical Uses of Arsenic.' "Mr. Jeremiah J. Foster, 'On the History, Nature and Properties of Oxygen Gas.' "Mr. J. C. Foster, 'Objections to the Antiphlogistic Theory of Combustion.' "Mr. Charles Gignilliat, 'On Hydrogen Gas.' "Mr. John Bent, 'On Oxygen Gas.'" The monthly meetings were announced in the city papers. The announcements appeared at intervals through a period of years, hence it may be assumed the Society was an active organization and that its members regarded it as of consequence. The personnel of its official family is not devoid of interest at present. A single volume of memoirs, printed in 1813, is still extant and may occasionally be seen; from it will be learned that the "Hon. Thomas Jefferson, Esq., was the Patron" of the Society and its President Turning to the table of contents two contributions from the President are observed. 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 Arsenic." There is little chemistry in the first contribution, and the second possesses value chiefly in the qualitative way. They were evidently dashed off with the idea of arousing discussion, in the hope that serious efforts might be set in operation in certain directions. The thought which intrudes itself in looking through the Memoirs, noting the character of the individuals in the membership, and upon recalling the chemical activities of Cutbush, is as to "Bleaching Liquor, Artificial Musk, Phosphate of Mercury and other chemical Preparations, prepared and sold by "JAMES CUTBUSH "where complete collections of chemical reagents are kept as usual." Here is a hint as to the occupation of Cutbush. He was a chemist—presumably a manufacturing chemist, supplying the necessary reagents to persons desiring them for their chemical studies; and further he was a pharmacist serving the various requirements of the medical men of the City. Thorough search through newspaper files disclosed that from the year 1811 and perhaps two years earlier, and extending up to the year 1813—various announcements were made by Cutbush as to lectures of a public nature. These help us realize the character of the individual and his work. For example— "Dr. Cutbush's course of Evening Lectures on Chemistry will commence early in the second week in November, at the Laboratory in Videl's Court, in Second, near the Corner of Chestnut St." and several months later the following notice was found— "LECTURES "The subscriber, at the solicitation of several medical gentlemen, proposes to give a series of Lectures on the Theory and Practice of Pharmacy, accompanied with the necessary chemical elucidations. "Tickets may be had at 25 South Fourth St. "Price 20 dollars. This was in the year 1812. Early in 1813, a year after the preceding announcement, there appeared "J. Cutbush has the pleasure to announce to the ladies and gentlemen composing his class that the lectures on Chemistry, as well as those which are to follow on Mineralogy and Natural Philosophy, will be given in St. John's Lyceum in a building lately erected at the Corner of Chester and Race, between Eighth and Ninth Sts. "N.B. The next lecture will be delivered this evening (Saturday) when, at the request of several ladies, the nitrous oxide or the exhilarating gas will be exhibited." These announcements exhibit a phase in the development of chemical science which is worthy of pause and reflection. Science subjects had taken hold of many persons in the early years of the Nineteenth Century. Some of them became ardent enthusiasts and missioners in the It was in 1802 that Patrick K. Rogers received his medical degree and embarked upon practice. Having spare time, he began public lectures on the sciences, confining himself from 1807 to chemistry. He was very successful. "EVENING LECTURES "Having commenced a course of experimental lectures on Chemistry to ladies, proposes to give a similar course to gentlemen at a different hour. Twelve o'clock is the hour fixed for the former, but as the gentlemen of the city are variously engaged in business during the day, an evening hour will be more convenient for them. The evening course is particularly intended to accommodate men who have a taste for scientific information and who cannot, on account of their respective engagements "A course for gentlemen will commence on Tuesday and will terminate in the last week of February. The hour will be seven o'clock in the evening. Two lectures at least, sometimes three, will be delivered every week. About 1500 interesting experiments will be exhibited and submitted to the familiar inspection of the class. Several important experiments not hitherto introduced in any series of chemical demonstrations in this place will be displayed in the illustrations of different subjects. "The laboratory is in the lecturer's house in South Ninth Street, opposite the University and is furnished with an excellent chemical apparatus. "The tickets for this course will be ten dollars. The persons to take tickets "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 list. "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 lecture, properly the first of the regular series, will be delivered. Gentlemen are not admitted to these lectures." In 1810 Dr. Rogers gave out a Syllabus of 12 octavo pages "On Experimental Lectures on Natural Philosophy and Chemistry," in which great emphasis was laid on the practical application of these sciences. It also stated that "it is even esteemed, in some measure, a Another participant in the science propaganda was Dr. Thomas P. Jones, who devoted himself to Chemistry. The "On Saturday, the 13th inst., at seven o'clock in the evening, at Dr. Jones' Chemical Lecture Room, S.W. Corner of Fourth and Chestnut Streets, a lecture will be delivered on the properties of nitrous oxide, or the exhilarating gas, accompanied with a number of experiments. A large quantity will be prepared to exhibit its effects when inhaled. "Tickets at fifty cents each may be had at A. Finley's Bookstore, S.E. Cor. of Chestnut and Fourth Streets, or at the lecture room on the stated evening." On perusing early chemical texts and advertisements, such as those just given, attention is pointedly called to nitrous oxide, especially to its exhilarating "THE ONLY GENTEEL WAY OF GETTING DRUNK "A character representation of the effects produced by inhaling nitrous oxide gas. The accuracy of which no man breathing can deny. Price 25cts." To-day, nitrous oxide means a benign anÆsthetic, so helpful and merciful when one is brought under the knife of the skillful surgeon. The honor accorded Cutbush by his election to the Presidency of the Columbian Chemical Society was merited. He was not only an active, intelligent chemist, devoted to the advancement of his science in all directions, but he seems to have been an ardent enthusiast in the Little can be found in regard to the Society for the Promotion of a Rational System of Education, but it may be inferred that the society had branches throughout the city and perhaps far beyond, because elsewhere Cutbush spoke of the society as under the Presidency of John Goodman, Esq., and that its purpose was to bring about a reformation in education. Further, Goodman was a prominent layman in the Church of Old St. John, who with his associates, Messrs. Greiner and Braeutigam, fellow churchmen, deeply impressed Desirous of learning something in regard to St. John's College, the authorities of St. John's Lutheran Church were consulted. It must be remembered that this is the oldest English-speaking Lutheran Church in America. It was founded by General Peter Gabriel Muhlenberg, and a unique distinction of this church is that in a period of 113 years it has had but three pastors. Nothing in the minutes of the church showed that a movement toward the establishment of a college had ever been Benjamin Smith Barton was another professor in St. John's College, who devoted himself to Natural History and Botany. Mr. Greiner, who was associated with Messrs. Goodman and Braeutigam also taught in the institution, and the head of the college or school was a Mr. Bachman, who later became a Lutheran clergyman and naturalist of high repute in South Carolina. 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 constitution. Among other things, it is said "the education of youth in The copy of Oration on Education, printed by Cutbush, which it was the privilege of the writer to peruse, was the copy handed by Cutbush "To Dr. Seybert with the compliments of the author." In spite of age, these words are very clear and legible, and if the only relic by which to judge of the character There were many other societies extant at this period and through subsequent years which had for their object the promotion of scientific education. Among these was the Linnean Society, of which James Cutbush was Vice-President. Cutbush had the honor of being one of the few of the original Society of Philadelphia for the Promotion of National Industry, whose essays excited the attention of the citizens of the United States. Samuel Jackson, M.D., Professor in the College of Apothecaries, was one of the most active members. Amidst all the activities of Cutbush as a manufacturing chemist, as a teacher of the science, as a promoter of educational reforms, as a member of many organizations, he was very busy In the year 1813, Cutbush placed before the public his "Philosophy of Experimental Chemistry" in two volumes. It was dedicated to the "Professors and Students of the University of Pennsylvania and to the Trustees of St. John's College." 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 Ægis of the University. Indeed, The little contribution on the "Philosophy of Chemistry" was favorably known, for Silliman, in his reference to Gorham's Chemistry as the first book upon this subject by a native American, credits Cutbush with having written a "Several original works have, accordingly, appeared, and some editions of European treatises have been published with revisions, corrections and additions by our countrymen. The Chemical and Economical Essays of Pennington, the edition of Chaptal enlarged by the late James Woodhouse ... that of Henry's Chemistry by Professor Silliman of Yale College, with some others, evince not only the learning and talents of our countrymen, but a growing taste for the encouragement of learning and the acquisition of chemical "The first teacher of chemistry was Dr. Benjamin Rush ... who may justly be styled the father of chemistry in America. He commenced a course of lectures on this science in the then College of Philadelphia; and although chemistry at that day (1768) may be said to have been in its infancy, yet the Doctor did honour to the chair, the school, and his country. We now speak of him only as a chemist.... The advancement of chemistry in our city Many attractions are found in the Philosophy of Experimental Chemistry. The first discussion is that on Chemical Affinity. Two experiments are introduced. In the first it is stated "If equal parts, by weight, of sulphur and mercury be introduced into a crucible, and in this situation exposed to a sufficient heat; a compound will be formed, called sulphuret of mercury." In the second experiment the student is advised to "Mix together sulphur and potash, and throw them into water; the sulphur will separate. If the same articles be put into a crucible and melted, and then thrown into water, the sulphur as well as the potash will be dissolved." And next comes the "Rationale. In the first experiment there is an instance of chemical action, as well as of single affinity, for the sulphur and mercury would remain separate if heat was not applied. In consequence of this agent, they unite into an uniform whole, totally inseparable by mechanical means, and possessing characters distinct from either of its constituent parts. "In the second experiment, the union of sulphur with potash is effected by heat; for if a sulphuret was not formed, no solution of the sulphur would take place. Hence it is that chemical action is the consequence of a power, without which it could never ensue, and with which it always acts in unison. This power is affinity." Then it is remarked: "Chemistry is a science, which has for its object to discover the constituent Throughout the book the order of presentation is the experiment, rationale, and remarks. A study of the In discussing potash, Cutbush wrote: "It has been supposed ever since our countryman, Dr. Woodhouse, made an experiment with potash that this alkali had an inflammable base. 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 ways. The Doctor found that a mixture of pearl ash with soot, calcined by a very intense heat in a covered crucible, when cold caught fire on the affusion of water. 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 water." He says: "That Thomas Cooper ... repeated this experiment, and succeeded, I think, after several attempts, in procuring the metal. Dr. John Redman Coxe and myself also performed it, but in our attempt we failed. The professor, however, persevered, and finally procured it.... My brother, Dr. Edward Cutbush, succeeded in procuring it by using the heat of a black-smith's forge. I have not heard of any other attempts in this country except by a gentleman in New York, who was also successful." These statements substantiate the idea that Woodhouse isolated the metal potassium quite independently from any European chemist; it even looks as if he may have isolated it in the manner In the first volume of the Philosophy there is a frontispiece, a lamp furnace, consisting of a brass rod, fastened to a piece of metal, furnished with rings of different diameters, and thumb screws to raise or lower the lamp and rings when in use. By this furnace evaporation, digestion, solution, sublimation, distillation and other processes, which require a low temperature, may be performed. And in the second volume there is a frontispiece representing a portable universal furnace, made of strong wrought iron plates and lined with bricks bedded in fire-proof loam. The height of the furnace is two feet. The body of the furnace is elliptical. There are three openings in front of the furnace, Both pieces of apparatus represent a marked advancement. They were evidently exceedingly useful. By their means it was possible to execute excellent work. It would repay one to examine with care the various American text-books on chemistry, beginning about 1770 and continuing down to 1830. There would arise a picture before one's mind of the successive steps in the development of chemical apparatus, and again, the knowledge derived from the presentation of chemical theory and data would be refreshing and inspirational. It is to be hoped that the time is not far distant when some library, public or university library, will go to the trouble of gathering the American texts on Chemistry for Cutbush had little leisure during the year 1813, as he was engaged with the duties of the College and was conducting popular lectures on an extended scale. It was necessary for him to invite his friend, Dr. George F. Lehman, to assist in the various demonstrations. They emphasized not only the theory but the practice of chemistry with its application to the useful arts. Their experiments were numerous and were of such a character as to appeal to the general public. The course offered by In addition to the devotion of Cutbush to these didactic courses in chemistry, he spent much time in a literary way. One of the best-known publishers of the city announced the purpose of printing the American Artist's Manual under the editorship of Cutbush. The advertisement stated— "To manufacturers, however, who are presumed to be interested in practical knowledge the value of such works is greatly diminished by the multiplicity of theories, technical terms and complicated processes which they in general contain. It is, therefore, unnecessary to expatiate on the advantages to be derived from such a publication as is This extensive and helpful publication appeared in 1814 in two octavo volumes of more than 600 pages each. The reader should note that "The price to subscribers will be $7.00 in boards or $8.00 substantially bound, payable on delivery. Those who procure subscriptions of nine copies and become accountable for their payment shall be entitled to one copy for their trouble." The book was dedicated to Benjamin Smith Barton. No title of any kind appears after the author's name, indicating that he had probably by the year 1814 severed his connection with all his educational projects in Philadelphia. In the preface the author speaks of "Having devoted the greater part of his life to chemical pursuits." Glancing through these volumes the impression made upon the reader was that the author had read widely in the sciences, but particularly in his favorite science, chemistry. The book is really a popular dictionary of chemical technology. While it is sparsely illustrated, early forms of chemical glassware are pictured. From these may be gathered the story of the gradual development of very useful apparatus, for example, such as is used in various kinds of distillation. That Cutbush had probably ceased his professional duties by the year 1814, as has just been hinted, is further emphasized on noting that he was appointed Assistant Apothecary General in the U. S. Army on the twelfth day of August in the year 1814. What his duties as such may have been has not been discovered. It would not be fair to call it a radical change in position, but it was a change which necessitated Cutbush giving more thought and attention to pharmacy, which in his earlier career was a secondary subject, but in which he was so proficient that he attracted to himself the attention of leading men in medical circles. He was in Philadelphia, prosecuting his duties as late as the year 1819. It is known that during this period he was attached to the Northern Division of the Army. In 1820 Dr. James Lovell, Surgeon Just before leaving Philadelphia, in the year 1820, Cutbush wrote Benjamin But, returning to his life at West Point, it may be observed that in 1822 he contributed his second article to the Journal of Science, which did not appear in print, however, until 1824. This article related to the composition and properties of the Chinese fire and the so-called brilliant fires. It was very interesting. It displayed a thorough and wide knowledge of pyrotechnics with which Cutbush, in previous years, had been gradually familiarizing himself. At one point he said: "Most if not all the compositions used in fireworks, including military Here is every proof of his purpose to apply his understanding of chemical principles and his own experience to the solution of pyrotechnic problems, for he continues: "Pyrotechnics is at present considered under two heads, namely, fireworks for exhibition and military fireworks. Almost simultaneously there appeared in the same Journal of Arts and Science another contribution by Cutbush, 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 contribution. He says: "The Greek fire was invented by Callinicus of Heliopolis, a town in Syria, who used it with so much skill and "It appears that in the reign of Louis XV, a chemist of Grenoble, Dupre de Mayen, discovered a composition similar in effect to the Greek fire of Callinicus, which was exhibited at Brest, and proved successful, but the preparation was kept secret. The original Greek fire was used in 1291, and also in 1679.... Writers have defined it to be a sort of artificial fire, which burns with increased violence when it mixes with water.... That it was a liquid composition, we may infer from the modes of using it, which were several. It was employed chiefly on board of ships, and thrown on the vessels of the enemy by large engines. It was sometimes kindled in particular vessels, which might be called fire ships, and which were introduced "... John Cameniata, speaking of his native city, Thessalonica, which was taken by the Saracens in the year 904, says that the enemy threw fire into the wooden works of the besieged, which was blown into them by means of tubes, and thrown from other vessels.... This proves that the Greeks, in the "... On the subject of incendiary and other military fireworks, the French have certainly laid the foundation for the very preparations now used by the British, for the formulÆ for such "The Moors were in possession of the secret for preparing the Greek fire in 1432, according to the testimony of Brocquire. Bertrandon de la Brocquire was in Palestine in 1432 as counsellor to the Duke of Burgundy. He was present at Barrat during one of the Moorish celebrations. 'It began,' he remarks, 'in the evening at sunset. Numerous companies scattered here and there were singing, and uttering loud cries. While this was passing, the cannon of the castle was fired, and the people of the town launched into the air "bein haut et bein loin, une maniere de fue plus gros fellot que je veisse oncques allume." They told me they made use of such at sea, to set fire to the sails of an enemy's vessel. It seems to me that it is a thing easy to be made, and at a little expense The entire article from which these excerpts have been made is worthy of study, even at this late date. It is suggestive and carries with it many historical About a year later (1823) Cutbush discussed the formation of cyanogen in processes not previously noticed. He spoke of the appearance of this gas in the putrefaction of animal and vegetable matter, making the following remarkable and in some respects startling statement: "I believe it would be found that the compound (carburet of azote) is the basis of the miasmata which produces malignant, bilious diseases.... Marsh miasmata are generally the cause of intermittent fevers. Now under particular circumstances of action may we not admit the generation of carburet of Another observation made in this connection was that cyanogen is produced when charcoal is heated with nitric acid. Cutbush stated that he placed charcoal and nitric acid together in a retort and subjected them to distillation, collecting the product in Woulfe's bottles, after which the resulting solutions were impregnated with potash, and "common sulphate and persulphate of iron introduced. The colour instantly changed and became more or less blue, proving the existence of the perferrocyanite of iron and, consequently, of cyanogen." Having never met this method of preparing cyanogen, experiments were made in the writer's laboratory to verify the statement. A blue, or what had the semblance of a blue color, could be obtained at the point given by Cutbush, but just as soon as the solution was acidulated, as is always done, the precipitate disappeared and there was not the slightest indication that Prussian blue had been formed. Even after hours of rest there was not a sign of it. 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 "Molybdenite, kaolin, tremolite, schorl, adularia, garnet, actinolite, precious serpentine (remarkably elegant), epidote and diallage." Recently, attention has been called to a volume by Cutbush entitled "Lectures on the Adulteration of Food and Culinary Poisons.... With a Means of Discovering Them and Rules for Determining the Purity of Substances." It was published at Newburgh, N. Y., in 1823. The writer has never seen this volume. His search for it has been unsuccessful. Another publication was "A Synopsis The real magnum opus of Cutbush resulted in "A System of Pyrotechny" (1825), which voluminous publication did not appear until after his decease, and then largely through the efforts of his wife and former students in the Cadet Corps, for, in Silliman's Journal, this note appeared: "Mrs. Cutbush, widow of the late Dr. Cutbush, of West Point, proposes to publish by subscription a Treatise on Pyrotechny by her husband, Dr. James Cutbush.... By the reputation which Dr. Cutbush sustained, as well as by the ability which his elaborate treatises on these subjects already published Even to-day this publication stands out preËminently and for years has been referred to by artisans and by scientists. Chapters dealing with military fireworks have been seriously studied. In the light of the violent fires, grenades, etc., used in the late war the writings of Cutbush become very fascinating. They show that he truly blazed the way in this field. In the introduction to this splendid volume he wrote: "On this head, that of the application of chemistry to pyrotechny, we claim so much originality, as, so far as we know, to have been the first, who applied the principles of chemistry.... As this subject, however interesting to the Much time and thought were given by Cutbush in the experimental development of this particular subject in his own laboratory. In reading upon the subject he had collected a vast material which was then put to crucial An outline of how the work in the chemical department of the United States Military Academy was conducted will not be devoid of interest. First Year Theory and Experimental Chemistry. Second Year Application of Chemistry to the Arts, Manufactures and Domestic Economy, constituting along with Mineralogy the second course. Pyrotechny naturally was developed quite extensively. Teachers of chemistry will note with pleasure the questions which Cutbush arranged for his student corps, particularly those questions which had to do with pyrotechny: "What is saltpetre? What is nitric acid? What are the sources of saltpetre, and how it is obtained? How is it formed in nitre beds, extracted, and refined? What circumstances are necessary to produce nitre, and how does animal matter act in its production? What is the difference between the old and new process for refining saltpetre? What reagents are used to discover the presence of foreign substances in nitre? What are nitre caves? Where do they exist? What are the nitre caves of the western country, and how is nitre extracted from the earth? What proportion of nitre does the saltpetre of the nitrate caves afford? What is the theory of the process for extracting saltpetre from nitrous earth, or nitrate of lime? What is sulphur? How is it obtained, and how is it purified for the manufacture of gunpowder? Of what In the introduction to "Pyrotechnics" Cutbush remarked that he had "As respects the turtle torpedo and catamarin submarine machines, it appears that Bushnel claims the originality of the discovery from the date of his invention, although similar contrivances had long ago been suggested. Fulton's improvements, in the torpedo, are deserving of particular attention, 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 it." The "System of Pyrotechny" bears the ear-marks of much careful experimental study. It is a most worthy contribution, and is strong proof of the dominating force in the mind of Cutbush, namely, to make his science as The life story of Cutbush has now been told. It is really the story of his life activities, for regrettable as it is, there does lack a picture of the man's personality. The parents of James Cutbush were Edward Cutbush and Anne Marriat. The father was a stone-cutter or carver. To these good people were given four children: Edward, born in 1772; Ann, in 1782 (who died in 1798); William, born in 1785, and James in 1788. Edward became prominent as a naval surgeon, while William graduated from West Point in 1812, and attained eminence as an engineer. Indeed, at an early age, William was a midshipman in the United States Navy, and was taken prisoner by the Algerines at the time the frigate Philadelphia James Cutbush must have been a man of mark among his neighbors—as indicated by sundry positions of trust which he held. Further, he must have been a favorite with the Cadet Corps at West Point, where he was buried. His tomb there bears this inscription: "Sacred to the memory of Dr. James Cutbush, Member of the American Philosophical Society, Late Surgeon, U. S. Army and Professor of Chemistry at the U. S. Military Academy, West Point, N. Y., who departed this life December 15, 1823, aged 35 years. An honourable tribute of respect from his grateful pupils." The work of Cutbush was of the genuine pioneer character, and enriched the annals of American chemistry. While it would be delightful to know more of the man, cruel fate compels us to be content with the estimate, brief though it is, given in Poulsen's American Daily Advertiser, December 23, 1823: "A man not only known for his extensive knowledge of chemistry, but distinguished for his philosophy and patriotism."
