No. 4."Ernest Renan (1823-1892) was a French philologist, philosopher and historian. His father died when he was aged five, and his mother wanted him to become a priest. Until he was about 16 years old, he was trained by the Church, but due to his investigative and truth-seeking nature as well as his studies (e.g. Hebrew), he was in doubt as to the historical truth of the Scriptures, and with the help of his sister he chose his own path in life. "He studied intensively the languages of the Bible and filled a number of minor academic positions, frequently encountering difficulties because of the heterodoxy and outspokenness of his religious opinions." (Printing and the Mind of Man 352). In 1840 he began studying philosophy and later philology, in 1847 he took his degree as Agrégé de Philosophie and became master at the Lycée of Vendome. After having returned from a mission to Italy in the year 1850 where he gathered material for his historical-philosophical masterpiece, "Averroës et l'Averroisme", he was offered employment at the "Bibliothèque Nationale" (at the manuscript department). In 1861 he was chosen to become professor of Hebrew at the Collège de France, but because the emperor refused to ratify the appointment (inspired by the Clerical party), he was not established in the chair untill 1870. In 1878 he was elected for the Academy. Renan is considered a scolar of the greatest excellence and an impressive writer. Renan's closest confidante was his sister, Henriette, who helped him quit the clerical carrier. They helped eachother financially, travelled together (e.g. on archaeological expeditions) and lived together for many years of their lives. His widely famous work, "Vie de Jésus" is dedicated to her, and their correspondence is very interesting and catching.

(16), 910 pp. A fine copy of the first edition of Moller’s commentaries on the psamls of David, published the same year as he was awarded the rectorship in the Wittenberg Academy. After initially receiving school education in his birthplace, he enrolled at the University of Wittenberg on June 14, 1546. He came into contact with Philipp Melanchthon, who primarily guided him in his preferred studies of oriental languages. The following year he enrolled at the University of Rostock. Back in Wittenberg, he acquired the academic degree of Master of Philosophy on February 24, 1551 and was accepted into the teaching staff of the philosophical faculty on July 7, 1554. At Melanchthon's efforts, after Paul Eber resigned from his professorship of Hebrew at the philosophy faculty, Moller received the position of professor of the Hebrew language at the University of Wittenberg. At the philosophical faculty he took over the deanship in 1562 and held the rectorship of the academy in 1573 and the equivalent vice-rectorate in 1565. He also became an assessor at the Wittenberg consistory in 1573. Moller was drawn to theological studies; he was listed as a theologian as early as 1561 and read about the minor prophets from the original text of the Bible. When in 1574 at the state parliament convened in Torgau the disputes between Philippists and Gnesiolutherans were decided in favor of the latter through the Torgau Articles, Moller and other Philippists refused to sign. He was then imprisoned in Wittenberg, Torgau and Leipzig and finally expelled from Electoral Saxony. On August 8, 1574, he returned to Hamburg and pursued both theological and medical studies. This enabled him to work as a doctor, which he continued until his death from a stroke. Not in Adams.

Leningrad - Moskva (Moscow), Molodaja Gvardija, 1933. 12mo. Stapled, in the original coloured illustrated wrappers: Some minor wear along spine, resulting in a tear to lower hinge, virtually no loss. A bit of minor soiling. A very fine copy of this fairly fragile publication. With many illustrations throughout. (18) ff. The scarce first edition of Marschak's important political and social comment to Russian society, masked as a children's story. Marschak played a seminal role in the emergence of children's literature in Russia after the Revolution, and the present work constitutes a prime example of the political satire and comment for which this genre also served as a cover. In pre-revolutionary Russia children literature had been in somewhat of a stand-still since the appearance of the first journal for children appeared in 1785. Throughout the entire 19th century texts by Russian authors were counted as children's literature, although they had by no means been written as such, e.g. works by Puschkin, Lermontov, Gogol, Turgenjev, Tolstoj etc., etc. There was no such thing as actual children's literature in its own right. Not until the 20th century did this change. With the political and social changes after the Revolution of 1917, the field of children's literature would change, and Marschak was at the centre of this change. He was the director of the actual children's periodical "The New Robinson", which hired authors to write stories specifically for children. This must naturally have been a relief for the children, but as important was the fact that this sort of writing could become a refuge for the authors themselves. To a large extent the genre of children's literature was considered harmless and not something that was politically supervised; this meant that the authors could express them self much more freely here that they would normally be able to. And thus, it is among the children's literature around 1930 that we find some of the most politically interesting Russian works, Marschak's "Mister Twister" being a prime example. The moral story of an American racist, who travels to Russia, refuses to stay in a hotel-room next door to a black man and ends up without a roof over his head, could be seen as a tale for children which instructs them in how to treat people equally and not look down upon others. But as much as this, and perhaps more, the present pamphlet is an ingenious piece of political satire which plays off socialism against capitalism. What would have been impossible in adult literature, becomes possible in that for children, and Marschak masters the ambiguity to perfection. Furthermore, it is a work in which Marschak displays his thrill with the technical progress of RussiaThe work appeared in German in 1933

London, Philosophical Transactions, 1807. 4to. No wrappers as extracted from "Philosophical Transactions" 1807 - Part I. Pp. With titlepage to Part I. Pp. 1-56 and 1 engraved plate (showing the pile used). A bit of browning to the plate and a larger brownspot in right margin. Otherwise clean and fine, wide-margined. First printing of a MILESTONE PAPER IN ELECTROCHEMISTRY in which Davy shows that electricity is capable of decomposing the most stable elements."Humphry Davy was one of the most brilliant chemists of the early nineteenth century. His early study of nitrous oxide brought him his first reputation, but his later and most importent investigations were devoted to electrochemistry. Following Galvani's experiments and the discovery of the voltaic pile, interest in galvanic electricity had become widespread. The first electrolysis by means of the pile was carried out in 1800 by Nicholson and Carisle, who obtained oxygen and hydrogen from water. Davy began to examine the chemical effects of electricity in 1800, and his numerous discoveries were presented in his Bakerian lecture to the Royal Society on November 20, 1806 (the paper offered here). His experiments, along the lines stated in this paper, lead to his discoveries of potassum and sodium in 1807 and the year after to barium, calcium and boron.(A Source Book in Chemistry p. 243). - Sparrow: Milestones of Science No 52. - Wheeler Gift: 2511.

1917. 4to. Original vellum-backed portfolio. Gilt frontcover. Pictorial etched title-page, signed in pencil by the artist + etched contemt-leaf (Sexnam Listv.) and 6 original etchings, all numbered 9/50 (= no. 9 of 50 copies) and all signed by the artist in pencil. A few brownspots to frontcover. Etchings clean and fine. Max Svabinský (1873-1962) was a Czech painter, draughtsman, graphic artist, and professor in Academy of Graphic Arts in Prague. Svabinský is considered to be one of the more notable artists in the history of Czech painting and produced significant work during the first half of the 20th century. He was relatively unusual among modernist artists in that his work was accepted by the communist regime; this was due at least in part to his having formed his artistic personality prior to 1900, prior to the advent of cubism.

First European publication of this classic paper which announced one of the most celebrated experiments in the history of physics and eventually led Einstein to his Relativity Theory (see PMM 378,410,408). The paper appeared first in the "American Journal of Science" just one month before in November, not in August as stated in PMM. The offered paper appeared in the December issue 1887 and in a slightly modified form.Michelson was the first American to be awarded the Nobel Prize for Physics, in 1907, for the measurement of the speed of light through the design and application of precise optical instruments such as the interferometer, which was used in this experiment."Michelson, trained at the U.S. Naval Academy, and Morley, minister turned chemist, began a series of experiments to determine the relation of ether drift and the velocity of light, effects of extremely minute values. They used a slightly silvered glass set angular to a ray of sunlight so that a part ofthe ray was transmitted, a part reflected out and again returned, thereby providing two paths, one perpendicular to the other. If drift existed, the superimposed rays would produce interference. None was observed, showing that the earth's motion did not affect the light's speed. The negative result held revolutionary implications which led directly thru Lorentz and Einstein to the acceptance of new standards of reference of time and space from geometry and cosmometry."(Dibner).Dibner No 161 (listing the offered paper from Philosophical Magazine). - Norman 1505.- Magee "A Source Book in Physics", pp. 369 ff.

First appearance of a milestone-paper in the history of chemistry and atomic theory as Prout here set forth - coupled with experimental evidences - the theory that the elements seems to have atomic weights that are whole number multiples of the atomic weight of hydrogen and that all elements is in some way a combination of hydrogen atoms. The theory announced here in Prout's first paper on the subjecy, is called PROUT'S HYPOTHESIS, and it was "not until the twentieth century that new views of the atom, arising out of the Second Scientific revolution of the 1890s, revitalized the notion. As a result of the work of Soddy and Aston a new form of Prout's hypothesis was established and Prout was found to be not wrong, but merely a century premature."(Asimov)."The concept of a primary substance as the basis of all matter has a tempting simplicity which has appealed to thinkers from the classic Greek age to our own day. The idea was revived in a new garb in 1815-1816 by a London physician, Willia Prout, who observed that with few exceptions the specific gravities of elementary gases (i.e., their atomic weight) were evenmultiples of of that of hydrogen. The experimental errors in the data then available were such asto make the hypothesis appear plausible. Prout concluded, therefore, that hydrogen isthe fundamental constituent from which all other elements are compounded....... his idea that all matter is composed of the same material is now established."(Leicester & Klickstein in "A Source Book in Chemistry 1400-1900", p. 275 ff.). - See also note to PMM 407, entry Moseley The Atomic Table.Parkinson "Breakthroughs", 1816 C.

Paris, L'Imprimerie Royale, 1768. 4to. Extract from "Mémoires fe Mathematique et de Physique, Présentés à l'Academie des Sciences par divers Savans", Tome V. With tittlepage to vol. 5. Pp. 341-357. Clean and fine. First appearance of Lavoisier's FIRST PUBLISHED CHEMICAL PAPER introducing quantitative methods in chemistry, and in which he for the first time brought a hydrometer in use to measure the specific gravities of components of a chemical solutions. Lavoisier defended the originality of his approach in the following words: "It is to the art of combination that the knowledge of the specific gravities of fluids can bring most light. This aspect of chemistry is much less advanced than we thought, we possess barely the rudiments of it." "This first paper, which in so many respects embodies the quantitative methods Lavoisier was to employ in his later work, had in fact been largely anticipated by others, notably by Marggraf, who had already discovered the composition of gypsum and shown that it contained water (phlegm). Yet Lavoisier’s work was more through; and his paper, his first contribution to the Academy of Sciences (read to the Academy on 25 February 1765), appeared in 1768. (The paper offered). - Lavoisier’s earliest chemical investigation, his study of gypsum, was mineralogical in character; begun in the autumn of 1764, it was intended as the first paper in a series devoted to the analysis of mineral substances. This systematic inventory was to be carried out, not by the method of J. H. Pott "who exposed minerals to the action of fire" but by reactions in solution, by the "wet way." "I have tried to copy nature," Lavoisier wrote. "Water, this almost universal solvent "is the cheif agent she employs; it is also the one I have adopted in my work." Using a hydrometer, he determined with the care the solubility of different samples of gypsum (samples of selenite, or lapis specularis, some supplied by Guettard and Rouelle). He made similar measurements with calcined gypsum(plaster of paris). Analysis convinced him that this gypsum was a neutral salt, a compound of vitriolic (sulfuric) acid and a calcareous or chalky base. Not content with having shown by analysis the composition of the gypsum, Lavoisier completed his proof by a synthesis following, as he said, the way that nature had formed the gypsum. He further demonstrated that gypsum, when transformed by strong heating into plaster of Paris, gives off a vapor, which he showed to be pure water, making up about a quarter of the weight of gypsum. Conversely, when plaster of Paris is mixed with water and turns into a solid mass, it avidly combines with water. Using the expression first coined by Rouelle, he called this the "water of crystallization." (DSB).Partington III, pp. 378-79. -

First printing of Szent-Györgyi's landmark paper in which he for the first time discovered and isolated "hexuronic acid" or "ascorbic acid", today commonly known as vitamin C. In 1937 he was awarded the Nobel in Medicine "for his discoveries in connection with the biological combustion processes, with special reference to vitamin C and the catalysis of fumaric acid"."Szent-Györgyi is most notably associated with the discovery of vitamin C. The discovery of vitamins themselves was recognized in 1929 in a Nobel Prize to Christiaan Eijkman and Gowland Hopkins. The search for vitamin C was then well underway in several labs. Ironically, the compound had already been isolated by Szent-Györgyi. Though no one-not even Szent-Györgyi-yet knew its identity." (DSB). "In 1928 Szent-Györgyi had proposed that hexuronic acid, a highly reducing substance that he had isolated from oranges, cabbages and adrenal glands, was responsible for the anti-scurvy properties of fruit and vegetables, that is, that hexuronic acid was vitamin C. Zilva disagreed, citing work that he had done showing that vitamin activity and reducing power were independent of one another. There the matter lay for four years until, in 1932, Szent-Györgyi, carried out experiments to see whether hexuronic acid would protect guinea pigs from scurvy [which it indeed did]". (Smith, Nutrition in Britain, P. 45). At the same time, for five years King's laboratory at the University of Pittsburgh had been trying to isolate the antiscorbutic factor in lemon juice using the original 1907 model of scorbutic guinea pigs which developed scurvy when not fed fresh foods but were cured by lemon juice. They had also considered hexuronic acid, but had been put off the trail when a coworker made the explicit (and mistaken) experimental claim that this substance was not the antiscorbutic substance. Finally, in late 1931, Szent-Györgyi gave Svirbely, formerly of King's lab, the last of his hexuronic acid with the suggestion that it might be the anti-scorbutic factor. By the spring of 1932, King's laboratory had proven this but published the result without giving Szent-Györgyi credit for it, leading to a bitter dispute over priority claims.Garrison & Morton 1059

Warfare and the Age of Printing, 7008.The Italian physician, alchemist and cartographer, Alexis of Piedmont or Girolamo Ruscelli, was born in Viterbo, Italy around 1500 (perhaps earlier), and died in Venice, Italy around 1565. He is (probably) the author of the important "Secreti", published in 1555, and the "Secreti Nuovi", published in 1567, the first of which was extremely popular and of considerable influence, the second of which must be said to be of the greatest interest, but apparently not very widely read. He also translated the Geography of Ptolemy into Italian, and his books on war and fire-works are now quite scarce. Most of his works were popular in his life-time and the century to come, and they were translated into Latin, German, French and Welsh. At a very early point he indicated the plan of a scientific academy, and he must be said to be a very interesting 16th century scientist.

Gay-Lussac et Arago", tome XVIII. - Decembre 1821, pp. 337-448 and 1 engraved plate. (The entire December-issue). Faraday's paper: pp. 337-370. First appearance in French of this landmark paper in electromagnetism. The present paper is a translation into French of Faraday's seminal paper "On some New Electro-Magnetical Motions, and on the Theory of Magnetism", which was originally published on October 21 in "The Quaterly Journal of Science", between one and two months before the present French version, which was published in "Annales de Chimie et de Physique", in December the same year. The work contains the first published mentioning of the "LINE AND FORCE CONCEPT". Faraday employed a magnet and a wire with a flowing current, caused each separately to rotate round the other, and concluded that a current-carrying wire is surrounded by a circular "line" of magnetic force."Ever since Hans Christian Oersted's announcement of the discovery of electromagnetism in the summer of 1820, editors of scientific journals had been inundated with articles on the phenomenon...Inspired by the editor of Philosophical Magazine, Richard Phillips, Faraday agreed to undertake a short historical survey but he did so reluctantly, since his attention was focused on problems of chemistry rather remote from electromagnetism. His entusiasm was aroused in September 1821, when he turned to the investigation of the peculiar nature of the magnetic force created by an electrical current. Oersted had spoken of the "electric conflict" surrounding the wire and had noted that "this conflict performs circles", but this imprecise description had had little impact upon Faraday. Yet as he experimented he saw precisely what was happening. Using a small magnetic needle to map the pattern of magnetic force, he noted that one of the poles of the needle turned in a circle as it was carried around the wire. He immediately realized that a single magnetic pole would rotate unceasingly around the current-carrying wire so long as the current flowed. He then set about devising an instrument to illustrate this effect...and so his experiment records the FIRST CONVERSION OF ELECTRICAL INTO MECHANICAL ENERGY. (Based on the article in DSB).- Faraday's discovery of "the lines of magnetic force" became the starting point for the revolutionary theories of Clark Maxwell and later of Einstein.

In 1820 Oersted had generated magnetism from electricity, Faraday here finds the opposite effect, generating electricity by magnetism. He also described the first electrical generator (second paper). THESE PAPERS ARE SOME OF THE GREAT CLASSICS OF CHEMISTRY AND PHYSICS."Faraday demonstrated this theory involving the lines of force....by inserting a magnet into a coil of wire attached to a galvanometer. While the magnet was being inserted or removd, current flowed through the wire. If the magnet was held stationary and the coil moved over it one way or the other, there was current in the wire. In either case the magnetic lines of force about the magnet were cut by the wire.If the magnet and coil were both held motionless, whether the magnet was within the coil or not, there was no current...Faraday hd thus discovered electricalinduction...It was to lead to great things, but this was not apparent."(Asimov)."Although his discovery of the electric motor and the dynamo was almost entirely identical to his theoretical discoveries, it laid the foundation of the modern electrical industry - electric light and power, teælephony, wireless telegraphy, televison etc. - by providing for the production of continous mechanical motion from an electrical source, and vice versa."

In "Nature", May - October, 1908, Vol. LXXVIII [78]. Library label to first page of index and bookplate pasted on to front free end-paper. Fine and clean Fine and clean P. 151; Pp. 105-6. [Entire volume: LII, 686 pp.]. First printing of this seminal publication in the history of television; it is generally considered the earliest and most important paper in the early development of television. It constitutes the first description of an electronic method of producing television.Responding to an article in the June 4, 1908 issue of Nature by Shelford Bidwell entitled "Telegraphic Photography and Electric Vision," A. A. Campbell Swinton wrote a letter to the editor of Nature proposing a solution to the most pressing problems in achieving "distant electric vision": "This part of the problem of obtaining distant electric vision can probably be solved by the employment of two beams of kathode rays (one at the transmitting and one at the receiving station) synchronously deflected by the varying fields of two electromagnets placed at right angles to one another and energised by two alternating electric currents of widely different frequencies, so that the moving extremities of the two beams are caused to sweep simultaneously over the whole of the required surface within the one-tenth of a second necessary to take advantage of visual persistence." (SWINTON)."The final, insurmountable problems with any form of mechanical scanning were the limited number of scans per second, which produced a flickering image, and the relatively large size of each hole in the disk, which resulted in poor resolution. In 1908 a Scottish electrical engineer, A. A. Campbell Swinton, wrote that the problems 'can probably be solved by the employment of two beams of kathode rays' instead of spinning disks. Cathode rays are beams of electrons generated in a vacuum tube. Steered by magnetic fields or electric fields, Swinton argued, they could 'paint' a fleeting picture on the glass screen of a tube coated on the inside with a phosphorescent material. Because the rays move at nearly the speed of light, they would avoid the flicker problem, and their tiny size would allow excellent resolution. Swinton never built a set (for, as he said, the possible financial reward would not be enough to make it worthwhile)..." (Britannica). Hiers, Early Television no 366.

Leipzig, Gross & Fritsch, 1724. 4to. Entire volume present. Nice contemporary full vellum. Small yellow paper label pasted to top of spine and library-label to inside of front board. Two smaller library stamps to title-page. Internally some browning and brownspotting, due to the paper quality. Overall a nice and tight copy. [Riccati-paper:] pp. 66-73. [Bernouilli-paper:] pp. 73-75. [Entire volume: (2), 532, (34) pp.]. The important first printing of Riccati's main work, his influential "Animadversiones in aequationes differentiales secundi gradus", in which the famous Riccati-equation is presented + Bernouilli's famous note on it."In his "Animadversiones in aequationes differentiales secundi gradus," published in Acta Eruditorum in 1724, Riccati suggested the study of cases of integrability [...] which is now known by his name. In response to this suggestion Nikolaus II Bernoulli wrote an important treatise on the equation and Daniel Bernoulli presented, in his Exercitationes quaedam mathematicae, the conditions under which it may be integrated by the method of separation of the variables. Euler also integrated it." (DSB, XI)."In the supplement volume to Acta Eruditorum, Riccati's paper is immediately followed by Daniel Bernoulli' Notata (St. 5.). As the latter admitted in the Exercitationes, he had Riccati's paper in his hands for two days before it was sent to Leipzig. In this short paper Daniel Bernoulli first claims that equation (D) is not an appropriate example because by substituting dy=q it can easily ("Haud magno negotio") be reduced to a first order differential equation." (Die Werke von Daniel Bernoulli, 1996, Birkhäuser, Volker Zimmermann (edt). "Riccati ( 1676 - 1754) was the son of a noble family who held land near Venice. His renown was such that Peter the Great invited him to come to Russia as president of the St. Petersburg Academy of Sciences. [...]. Riccati carried on an extensive correspondence with mathematicians all over Europe. His work were collected and published, four years after his death, by his sons, of whom two, Vincenzo and Giordano were themselves eminent mathematicians. (DSB, XI).

Paris: Gauthier-Villars, 1873. 4to. (282x225mm). Entire volume (1628 pp.) offered here in original blank wrappers, unopened. An exceptionally fine copy. 4 parts First edition of Hermite's epoch-making memoir in which he proved the transcendence of e, and thus initiated a new era in number theory. A decade later Lindemann used the method of Hermite's work to establish the transcendence of pi.

(Amsterdam ?), 1746. 4to. Samtidigt marmoreret hellæderbind. Overdådig rygforgyldning, forgyldt skindtitel. Lidt slidt ved øverste kapitæl. Rigt illustreret med kobberstukne portrætter, vignetter, prospekter, våbenskjolde i rokokomaner og foldede genealogiske tavler. Et blad fint repareret for en revnedannelse, uden tab. Et blad med en lille hul i teksten, uden tab. Enkelte brunpletter, men frisk, trykt på skrivepapir. Originaludgaven af Hofmans hovedværk, som siden udkom i en dansk udgave (1777-79). Hans omgang i Paris med tidens fornemste bogkunstnere gav ham smag for den nye franske bogkunst og han knyttede mange af disse kunstnere til udgivelsen af dette værk og dets pompøse udsmykning, således blev hans eget portræt, som indleder værker, stukket af den fremtrædende franske kunstner J.G. Wille. I værket redegøres for over 40 danske adelsslægter, Friis, Skeel, Rantzau, Thott m.v., og særligt må fremhæves afsnittet om Tycho Brahe, der ud over hans stukne portræt, indeholder kortet over Hven, prospekt af Uranienborg m.v.
