ADDEESS BY H. CARRINGTON BOLTON, VICE PRESIDENT, SECTION C. Fellow Members op the Chemical Section ; Ladies and Gentlemen : — The recognition by the Association of the equal rights of chem- ical science and the elevation of the late " Permanent Subsection " to the dignity of a "Section of Chemistry," now assembled for the first time, mark an important epoch in the annals of our organ- ization. Permit me to offer congratulations on our promotion and to express my high appreciation of the honor of presiding over your deliberations. The Permanent Subsection of Chemistry was organized at the Hartford meeting of the Association in 1874. It had its origin in the action of a number of chemists assembled at Northumberland in August of the same year to commemorate Priestley's discovery of Oxygen. At that memorable gathering a discussion of the advantages of forming an independent organization in the interests of chemistry led to the appointment of a committee* "to co- operate with the American Association for the Advancement of Science at their next meeting, to the end of establishing a chem- ical section on a firmer basis." This committee met at Hartford a few weeks later and united with the chemical members of the Association in founding a Per- •Thc committee consisted of Profs. Silliman, Smith, Hoiafoid, Hunt and Bolton. (3) 4 ADDRESS BY manent Subsection in accordance with tlie provision ^^^^ constitution adopted at tlie same meeting.

In tlie following yeai ''"c met at Detroit and tlie Subsection re- assembled under tie c ^^^^^ raanship of Prof. S. W. Johnson. Before adjourning the ^^^ ^^^^ elected Prof. Geo. F. Barker chairman for the ensuing year am passed a resolution requesting the ciiairman-elect to piep address. This was the origin of the custom which it is my pleasan duty to follow. Professor Barker accepted the task and his masterly essay on tlie Atom and the Molecule (1876) is remembered by many in this audience. Since tlien Prof. F. AV. Clarke (1« <8) has nrged in your hearing the endowment of laboratories of research ; Prof. Ira Remsen (1879) has magnified the claims of his chosen field of investigation— organic chemistry; and Prof. J. M. Oi-d- way (1880) has gracefully surveyed the experiences of the past, the needs of the present and tlie prospects of the future of chem- istry. _ _ The amendments to the Constitution, adopted by the Association at the Cincinnati meeting, provide, as you are aware, for nine sec- tions, each with its own presiding officer; since this may involve an equal number of annual addresses, it is hardly to be expected that each will maintain the elaborate character of those of former years. I ask you therefore to bear this fact in mind while I invite your attention to a rather superficial survey of CHEMICAL LITERATURE. The literature of chemistry, extending as it does through a period of more than fourteen centuries, varies greatlj' in character, in province and in design ; it partakes of the peculiar pliases exhibit- ed by the science at diflferent epochs and depicts the experiences and thoughts of those who cultivated it in all ages. It may be studied from several points of view : the biographer searches the voluminous records to acquire knowledge of the intellectual activ- ity of individuals ; the historian unfolds the progress made by the science in a special field or in its entirety, with philosophical in- quiries respecting eflfects and causes ; the bibliographer, scarcely penetrating beyond the title pages of the dusty tomes, laboriously catalogues them to facilitate the researches of others. H. CARUINGTON BOLTON. O We do not propose to give j'ou a biographical, an historical or a bibliographical treatise, but rather to review chemical writings as sources of information and as portions of the world's literary productions. "VVe shall concern ourselves less with the questions what were the personal history and life-work of a given author, and more with the queries what are the characteristics of the vari- ous classes of works at different epochs, what discoveries do they chronicle and what was their influence on the contemporaneous science. The very earliest information concerning chemical arts comes to us from that ancient nation supposed by some to have given its own name to the science itself; not onl}' do the sculptured tombs and temples of Egypt portray with unimpeachable authenticity and wonderful accuracy the technical skill of that venerable peo- ple, but these same monuments ai'e even now relinquishing their hold on long-buried treasures in the form of papyri, whose perplex- ing script no longer conceals their meaning from the erudition of Egyptologists. Of these miraculously preserved papyri the most valuable to chemistry is that discovered by Prof. George Ebers at Tliebes in 1872, and named after its learned discoverer. We have described this elsewhere ^ and shall not here enter into details. It is the most ancient medical work extant, being assigned to the sixteenth century B. C., and contains a vast amount of information on the medical practice and the pharmaceutical preparations at that re- mote period. The unknown author wrote less obscurely than many of a much later date, and when the whole papyrus shall have been deciphered it will prove an invaluable contribution to chemical history. The most ancient manuscript treating exclusively of chemical operations is a Greek papj'rus of Egyptian origin preserved in the Library of the University of Leyden. Its authorship is unknown, its date is placed by Reuvens in the third or fourth century A. D. This MS. consists of a collection of prescriptions and receipts for conducting various operations in metallic chemistry, such as the testing of gold and silver; the purification of lead, of tin and of silver ; the hardening of tin and of silver ; the albification of cop- per, etc. It deals little with alchemy though some of the receipts evidently refer to transmutations, as those entitled : " the prepara- 6 ADDRESS BY tion (artificial?) of silver;" "the preparation of gokl ;" "the pu- rification of tin by silver," etc. . , Eeference is made to sandarach (realgar), cadmia (zinc ore), ehrysocolla, cinnabar, natron (soda), mercury and other chemical substances, but no receipts are given for their preparation. The author quotes from the Materia Medica of Dioscorides who prob- ably preceded him by about two centuries. It is to be regretted that the full text of this ancient manuscript has never been piib- lished ; the little known of it foreshadows information of great in- terest.2 The great libraries of Paris, Rome, Venice, Milan, Escurial, Cracow, Gotha, Munich and Cologne preserve a large number of Greek alchemical manuscripts of unknown authorship and uncer- tain date. Hoefer, the French historian of chemistry, refers them to the third and fourth centuries,^ but other authorities with greater probability place them not earlier than the tenth and eleventh.* The most celebrated of these essays are attributed to Zosimus, of whose history nothing is certainly known, and bear these titles : "On Furnaces and Chemical Instruments," "On the Virtue and Composition of Waters," "On the Holy Water," "On the Sacred Art of Making Gold and Silver." In a treatise attributed to Sy- nesius, we find a description of a hydroscopium or hj-drometer which was rediscovered as long after as the sixteenth century. In a treatise attributed to Olympiodorus, he cites as authorities Democritus, Anaximander, Zosimus, Pelagius, and Marie a certain Jewess whom the later alchemists confounded with Miriam, Moses' sister. In these manuscripts chemistry is called the "sacred art" and the exceedingly obscure and figurative language in which they are written makes it well nigh impossible to separate fact from fancy ; Hoefer has indeed attempted to discover modern chemical concep- tions in the allusions to Egyptian myths and the chaotic collec- tions of spagyric arcana. Of systematic nomenclature thei-e is absolutely no trace ; indeed each author seems to have aimed to write treatises intelligible only to himself, and we greatly doubt his success in even this re- spect. " Cadinia," we are informed, " is magnesia," and " m^^nesia is the female antimony of Macedonia;" "nitre is white snlphnr which produces brass ;" equally clear is the statement that the bi-fl^S,;"' CARRINGTON BOLTON. 7 ''aposperaiatisra of the dragon is the mercury of cinnabar." That lexicons were early in demand is not surprising ; in fact some of the most ancient MSS. are "vocabularies of the sacred art," but even with their assistance it is difficult to form satisfactory concepts of contemporary chemical science. Suidas,5 a Greek lexicographer of the eleventh century, states that Diocletian having conquered the rebellious Egyptians (296 A. D.) destroyed their books on the preparation of silver and gold, lest becoming rich by the practice of that art they might again resist the Komans. Regrets at the wanton acts of this imperial biblioclast are tempered by the reflection that modern scholars are spared the study of such literary absurdities. The Chinese, that curious people who always claim a hearing when the origin or antiquity of arts and sciences is under consid- eration, were acquainted at a very remote period with many branches of chemical technology. We do not know of any special chemical literature produced by them, but the researches of Rev. Joseph EdkinsS and of Dr. W. A. P. Martin'' make it highly probable that scholars will yet discover contributions of no small importance to the early history of chemistry. Prof. George Glad- stone ^ has endeavored to ,show that the Chinese originated the doctrines and pursuit of alchemy and communicated it to the Ara- bians by whom it was disseminated throughout Europe. The high state of civilization and extraordinary intellectual de- velopment of the Arabians has left a deep impression on chemical science. Cultivated chiefly by physicians, attention was directed to its pharmaceutical applications, and in spite of the prohibitions of the Koran to the fascinations of alchemy. Of their extant writings, preserved in European libraries, only a portion have been edited ; those best known partake of the poetical imagery and hy- perbole characteristic of the Oriental mind. This is shown to some extent in the singular titles prefixed to their treatises, e. g., "The Rise of the Moon under the Auspices of Golden Particles," by the alchemist Dschildegl ; "A poem in the Praise of God, of Ma- homet and of Alchemy," by Dul-nun-el-Misri.s The well known treatises of Geber,i'"'Of the Investigation of Perfection," "Of the Sum of Perfection," "Of the Invention of Verity," and "Of Furnaces," notwithstanding a bewildering style of composition, which seems to confirm Dr. Johnson's derivation of O ADDRESS BY gibberish, from Geber, display very great familiarity with a large number of chemical substances and operations. Geber's works are generally assigned to the eighth century and consist chiefly of compilations from the "Books of the An- cients ;" he mentions no author by name. They contain chapters devoted to the seven known metals, to the methods of distil- lation, calcination, cupellation and other operations, to the prep- aration of saline substances and to chemical philosophy. Geber adopted Aristotle's views of the constitution of matter from four principles, the hot and cold, the wet and the dry, and addstliereto : "Mercury and sulphur are the components of metals," a doctrine which with slight modifications prevailed for more than eight cen- turies. Geber describes the preparation of nitric acid, of aqua regia, and of mercuric oxide ; he mentions the increase in weight of metals when calcined with sulphur, and gives the results of a rude quantitative analysis of crude sulphur. He constantly maintains the doctrine of transmutation of metals and gives a refutation of the ingenious arguments opposed thereto. His remarks on the qualifications of a chemist are most intelligent and are not inop- portune in modern times; he urges the necessitj' of diligence, patience, learning, a temperate disposition, slowness to anger, and a full purse, " for this science agrees not well with a man poor and indigent, " together with faith in the God who " withholds or gives to whom he will" the secrets of nature, and who will infallibly punish the foolish meddler with magical mysteries. To detail fully our obligations to Arabian chemists is no part of our plan. They have left an indelible impression on the very lan- guage of the science, in the words alcohol, alembic, alkali, borak, and many others. All honor to the intelligent authors who a thou- sand years ago defined chemistry as the " Science of Combustion, the Science of Weight, the Science of the Balance ! " i' In the middle ages intellectual activity was confined largely to the clergy, who controlled the schools of learning, the libraries, and nearly all sources of knowledge. University- chairs were oc- cupied exclusively by clerical professors'-, literature and science were cast in ecclesiastical moulds. Scientific treatises were the production of monks and emanated from cloisters. Many distin- guished philosophers mastered widely separated branches of learn- ing: among these were Alain de Lille (b. IIU), celebrated as a II. CARRINGTON BOLTON. 9 physician, tlieologian, poet and liistorian, who filled the epiiscopal chair at Auxerre ; Roger Bacon (b. 1214) an English cordelier ; Raymond Liilly (b. 1235), a Franciscan friar, and Albertus Mag- nus (b. 1193), Bishop of Ratisbon. The latter, amid the monoto- nous routine of a Dominican monastery, found leisure to distinguish himself iu astronomy, medicine, alchemy and, according to his ene- mies, in necromancy. At this remote period, accusations of dealing with magic were not unfrequently made against those whose learn- ing and skill in experimental sciences excited envy and supersti- tious zeal. 13 To treat the writings of these eminent ecclesiastics as a part of chemical literature requires perhaps a stretch of the imagination, yet three hundred years ago they were regarded as masterpieces of the science and formed the text-books of students of alchemy. The writings of these ecclesiastical philosophers are as comprehen- sive as the branches of learning they cultivated, and incredibly voluminous ; Albertus Magnus' collected works fill twenty-one folio volumes. 1* But a small fraction of these treatises are occupied with science and chemistry ; and of this fraction there is in many cases a reasonable doubt as to their authenticity. In fact, nothing was more common than the ascription of work by an obscure second-rate writer to some celebrated philosopher of preceding ages, in order to give the work the stamp of authority, — a decep- tion which previous to the invention of printing was more readily accomplished. It became difficult thei-efore to distinguish the apocryphal writings from the genuine. The former, it is true, frequently betray them- selves by anachronisms and other blunders, but many ingenious wri-' ters avoided such traps by adopting an enigmatical style worthy of the Delphian oracles. Basil Valentine was the reputed author of works held in the very highest esteem by the alchemists of the Middle Ages, yet the very existence of this individual is seriously questioned. Mystery surrounds Valentine's entire history, and his writings were given to the world in a most dramatic manner ; according to tradition they were hidden in the wall of a church at Erfurt and long after his death a thunderbolt shattered the wall and revealed the precious documents. Whether Valentine was a real personage or not the works as- cribed to him exhibit great familiarity with many chemical sub- 1* 10 ADDRESS BY ^ n .. xu 1 +1,0 nh
