Leipzig, Barth, 1915. 8vo. In the original printed wrappers. Author's presentation offprint with the printed presentation statement on top of frontwrapper "Überreicht vom Verfasser" [i.e. "Given by the author"]. Offprint from "Annalen der Physik", Vierte Folge, Band 48, 1915. A very fine copy, near mint. Pp. 1103-1112. Scarce presentation offprint with the printed presentation of Smolukowski's important drift-diffusion equation or the Smoluchowski equation. Here he documented that In some cases, the average velocity field exists because of a force, for example, the equation might describe the flow of ions dissolved in a liquid, with an electric field pulling the ions in some direction. This is referred to as the drift-diffusion equation (not to be confused with the Einstein-Smoluchowski relation)

(London, Harrison and Sons, 1879). 4to. No wrappers as extracted from "Philosophical Transactions" 1878 - Vol. 169 - Part II. Pp. 563-575 a. 2 lithographed plates. Clean and fine. First printing of this pioneer paper introducing the concept of NEURAL NETWORKS and initiating the "NEURON DOCTRINE"."His early histological work on the nerves of the jellyfish Aurelia aurita led to his very early promotion of the idea that nerve cells are structurally and functionally independent units.... This later became known as the ‘neuron doctrine’... Schäfer was led to study the structure of the subumbrellar nervous plexus in Aurelia aurita. He found that each nerve fiber was distinct from and nowhere structurally continuous with any other; he thought it reasonable to assume fiber-to-fiber transmission from "inductive action," possibly electric, the result being the same as if there were a real network."(DSB).

(Paris, Crochard, 1838). No wrappers. In: "Annales de Chimie et de Physique, Par MM. Gay-Lussac et Arago.", 2e Series, Tome 68, Cahier 3 entire issue offered. Pp. 225-352. Wöhler & Liebig's paper: pp. 225-336. First French edition of this importent paper in the development of organic chemistry. It is the last joint paper of importence from "these two men, ...pioneers in the development of organic chemistry, form a twin constellation in the chemical firmament"(Alexander Findley in "A Hundred Years of Chemistry", p. 23). The paper is a translation of "Untersuchungen über die Natur der Harnsäure", published at the same time in Justus Liebigs Annalen der Chemie (1838), Wöhler and Liebig collaborated on one more major piece of work, a study of uric acid. (The paper offered). Wöhler suggested the subject, and the idea seems to have come from his medical interests. Uric acid was not easily obtainable–snake excrement was the only substantial source–and relationships with urea and allantoin were suspected by Wöhler. As a student he had won a prize in 1828 for an essay on the conversion in the human body of chemicals taken orally and excreted in urine. The technique adopted by Liebig and Wöhler was to subject uric acid, ad the derivatives they prepared, to oxidation and reduction by reagents of different concentrations and strengths. Wöhler seems to have been the first to heat reagents together in sealed glass tubes, but after an explosion he thought metal ones safer.Their 100-page paper described fourteen new compounds and their preparation and analysis.7 An attempt to establish a new radical called "uril" (C8N4O4) was less successful. Perhaps even more significant than the sophisticated, practical and theoretical organic chemistry was the new spirit revealed. Writing to Berzelius in 1828, Wöhler was doubtful whether animal substances could be prepared in the laboratory. In 1832 he began the paper on the benzoyl radical with a description of organic chemistry as "the dark region of organic nature." But in 1838 his work with Liebig led him to write (at Liebig’s suggestion): "The philosophy of chemistry will conclude from this work that it must be held not only as probable but [as] certain that all organic substances, insofar as they no longer belong to the organism, will be prepared in the laboratory. Sugar, salicin, morphine will be produced artificially. It is true that the route to these and products is not yet clear to us, because the intermediaries from which these materials develop are still unknown, but we shall learn to know them."(DSB).

Deville's paper: pp. 857-861. First printing of Deville's first paper on "Dissociation", establishing a new type of high temperature chemistry."The effect of heat on chemical reactions was of particular interest. From the time of Bergman it had been realized that reactions often followed a course at high temperatures which differed from that followed at lower ones. In 1857, Henri Deville began a eries of studies which established quantitatively a new type of high- temperature reaction... In the course of his studies on the preparation of sodium and potassium and their use as reducing agents in the manufacture of other metals, Deville often used high temperatures. He was aware of the decompositions which often occurred under these conditions, and he suspected that such decompositions were of very frequent occurrence. He therfore undertook the study of reactions which occurred reversibly at high temperature. Such reactions he called 'dissociations', and by an extensive series of studies he showed the importence of dissociation as a general phenomenon in chemistry." (Leicester a. Klickstein "A Source Book in Chemistry", pp. 392 ff.).

Oxford, The Clarendon Press, 1935. Royal8vo. Orig. full cloth, gilt. With dustjacket. Jacket frayed, mainly at upper edges and on top of spine. VIII,(2),365,(1) pp., 2 plates, textillustrations. Clean and fine. First edition of Milne's controversial work "in which he introduced a new deductive system of theoretical physicswhich came to be called kinematic relativity. He introduced the useful term "cosmological principle" to signify that observers associated with galaxies in his model and in many others, including those based on general relativity, would see similar "world pictures". Milne went on to derive from his model many properties analogous to the laws of dynamics, gravitation, and electromagnetic theory. These developments of his theory were not generally accepted, and it is now thought that the most important effect of his work was that it led to fresh attempts to analyze the concepts of time and space-time."

First appearance of the paper in which Unverdorben describes the method by which he discovered Aniline, which became so importent in the manufacture of dyes, plastics, and pharmaceuticals. "Aniline (from the Portugese anil, applied to indigo, and derived from the Arabic an-nil, the blue substance), was first obtained by Unverdorben by heating indigo, and was given the name 'crystalline'. In 1841 Carl Julius von Fritzsche (1807-71), an assistant to Mitscherlich and, later, a member of the Academy of Sciences in St. petersburg, obtained the same compound from anthranilic acid, which was produced by the action of caustioc alkalis on indigo, and called it 'aniline'... in 1843 Hofmann showed that the three substances, crystalline, aniline and benzidam, were identical with the base isolated from coal tar."(Findlay "A Hundred years of Chemistry", p. 134).Parkinson "Breakthroughs" 1826 C.The volume contains other importent papers Antoine Jerome Balard "Ueber eine besondere Substanz im Meereswasser" in which he describes his discovery of the element BROMINE, first German edition, pp. 114-124 a. pp. 319-336.

Library labels pasted on to front end-papers and stamps to title page, otherwise fine. Pp. 344-70. [Entire volume: VIII, 1064 pp + 4 folded plates]. First printing of Hasenöhrl's important paper in which he showed that electromagnetic energy E, enclosed in an empty box with perfectly reflecting walls, behaves, when the box is set in motion, as if it had a mass proportional to E - also often referred to as inertia of a cavity containing radiation. Since J. J. Thomson in 1881, many physicists like Wilhelm Wien (1900), Max Abraham (1902), and Hendrik Lorentz (1904) used equations for the so-called "electromagnetic mass", which expresses how much electromagnetic energy contributes to the mass of bodies. And Henri Poincaré (1900) implicitly used the expression m=E/c2 for the mass of electromagnetic energy."When Hasenöhrl returned to Vienna he wrote the series of papers for which he is best known, on electromagnetic radiation. of these the most important is the prizewinning essay on the effects of radiant energy within a moving cavity.2Using classical theory he showed that the trapped radiation increases the kinetic energy of the motion, the effect being equivalent to an increase in the apparent mass of the cavity.In his formula h?0 is the total radiant energy in the cavity and c is the velocity of light. Like other similar anticipations, this result was displaced by Einstein's more general theorem on the equivalence of mass and energy." (DSB)

Pp. 1-176 a. 1 folded engraved plate. (The entire issue offereed ("Heft" 1)). Clausius' paper: pp. 1-56. Some brownspots to right marginon some leaves. First printing of this importent paper, the seciond of C's papers in the working out of the Kinetic Theory of Gases. In the paper he states that he found an error in Maxwell's theory of gases, an error Maxwell was to admit as far more serious. "In his initial approach to the conduction of heat in gases, Maxwell drew a brilliant analogy between diffusion (a transfer of mass) and conduction (a transfer of kinetic energy), thereby making it possible to use the form of his diffusion equation to represent conduction, simply replacing the mass of a molecule with its kinetic energy. Clausius critized this adoption of the diffusion equation, because, given the assumptions, mass transfer would accompany the heat conduction and the process would not be one of energy transfer alone. He then offered a revised theory of conduction. "(DSB III, p. 308)."Clausius was one of the founders of the kinetic theory of gases and of the science of thermodynamics. He and Lord Kelvin at about the same time and independently announced the Second Law of thermodynamics. Clausius particularly developed the theory of thermodynamics by applying it to the study of gases and vapors."(Magie in "A Source Book in Physics", p. 228).
