First printing of an importent paper in cosmology in which Herschel's by analyzing a large number of stars, believed that he could explain the regularities he observed by assuming that the sun itself was moving toward a point in the consellation of Hercules. "Just as Copernicus had detroned the earth as the motionless center of the universe, so Herschel detroned the sun."(Asimov). - In this paper he tries to estimate the speed of the sun's motion.In a memoir published in 1783 Herschel had been occupied with the possibility that the sun was moving relative to the stars. "More than 20 years later (1805, in the paper offered) Herschel took up the question again, using six of the brightest stars in a collection of the proper motions of 36 published by Maskelyne in 1790, which were much more reliable than any earlier ones, and employing more elaborate processes of calculation; again the apex was placed in the constellation of Hercules, though at a distance of nearly 30 degr. from the position given in 1783. Herschel's results were avowedly to a large extent speculative and were received by contemporary astronomers with a large measure of distrust; but a number of far more elaborate modern investigations of the same subject have confirmed the general correctness of his work."(Berry "A Short History of Astronomy", p. 346.).

(Paris, Gauthier-Villars), 1890. 4to. No wrappers. In: "Comptes Rendus Hebdomadaires des Séances de L'Academie des Sciences", Tome 111, No 21. Pp. (767-) 810. (Entire issue offered). Branly's paper: pp. 785-787. First appearance of the paper in which Branly announced his discovery that the electrical resistance of a granular metallic conductor could drop by several orders of magnitude when excited by the electromagnetic field emitted by an electrical spark, the so-called Branly-effect.The coherer was a key enabling technology for radio, and was the first device used to detect radio signals in practical spark gap transmitter wireless telegraphy. It became the basis for radio reception around 1900, and remained in widespread use for about ten years.

Berlin, G. Reimer, 1861. 4to. As extracted from "Journal für die reine und angewandte Mathematik, 59. Band, 1861". Without backstrip. Fine and clean. [Clebsch:] Pp. 1-62. First printing of Clebsch's early and founding paper on the symbolic method in invariant theory. The Symbolic method is based on treating the form as if it were a power of a degree one form, which corresponds to embedding a symmetric power of a vector space into the symmetric elements of a tensor product of copies of it."Clebsch completed the symbolic calculus for forms and invariants created by Aronhold, and henceforth one spoke of the Clebsch-Aronhold symbolic notation. Clebsch’s own contributions in this field of algebraic geometry include the following. With the help of suitable eliminations he determined a surface of order 11n - 24 intersecting a given surface of order n in points where there is a tangent that touches the surface at more than three coinciding points. For a given cubic surface he calculated the tenth-degree equation on the resolution of which the determination of the Sylvester pentahedron of that surface depends. For a plane quartic curve Clebsch found a remarkable invariant that, when it vanishes, makes it possible to write the curve equation as a sum of five fourth-degree powers. At the end of his life Clebsch inaugurated the notion of a "connex," a geometrical object in the plane obtained by setting a form containing both point and line coordinates equal to zero." (DSB)

(London, Richard Taylor, 1834). 4to. No wrappers as extracted from "Philosophical Transactions" 1834 - Part I. Pp. 55-76 a. 1 engraved plate. First appearance of a historical paper in chemistry and physiscs in which Faraday detects a new recombination-effect in electrolysis."In the course of his experimental investigations of a general and importent law of electro-chemical action, which required the accurate measurement of thegases evolved during the decomposition of water and other substances, the author was lead to the detection of a curious effect, which had never been previously noticed, and of which the knowledge, had he before possessed it, would have prevented many of the errors and inconsistencies occurring in the conclusions he at first deduced from his earlier experiments. The phenomena observed was the gradual recombination of elements which had been previously separated from each other by voltaic action. This happened when, after water had been decomposed by voltaic electricity, the mixed gases resulting from such decomposition were left in contact with the platina wires or plates, which had acted as poles; for under these circumstances they gradually diminished in vo.umes, water was reprioduced, and at lust the whole of the gases disappeared."(Abstract) - Faraday explains the causes of this recombination.From 1831 to 1852 Michael Faraday published his "Experimental Researches in Electricity" in The Philosophical Transactions of the Royal Society. These papers contain not only an impressive series of experimental discoveries, but also a collection of heterodox theoretical concepts on the nature of these phenomena expressed in terms of lines of forces and fields. He published 30 papers in all under this general title.They represents Faraday's most importent work, are classics in both chemistry and physics and are the experimental foundations for Maxwell's electro-magnetic theory of light, using Faraday's concepts of lines of force or tubes of magnetic and electrical forces. His many experiments on the effects of electricity and magnetism presented in these papers lead to the fundamental discoveries of 'induced electricity' (the Farday current), the electronic state of matter, the identity of electricity from different sources, equivalents in electro-chemical decomposition, electrostatic induction, hydro-electricity, diamagnetism, relation of gravity to electricity, atmospheric magnetism and many other."Among experimental philosophers Faraday holds by universal consent the foremost place. The memoirs in which his discoveries are enshrined will never ceaseto be read with admiration and delight; and future generations will preserve with an affection not less enduring the personal records and familiar letters, which recall the memory of his humble and unselfish spirit."(Edmund Whittaker in A History of the Theories of Aether and Electricity).

Small stamps on verso of titlepage.In: "Annales de Chimie, ou Recueil de Mémoires concernant la Chemie" Tome 75. 336 pp. a. 2 folded engraved plates. Some scattered brownspots. The papers: pp. 27-77, 129-175, 256-263, 264-273, 274-289 a. 290-316. First French version of Davy's "The Bakerian Lecture for 1809. On some new Electrochemical Researches, on various Objects, particularly the metallic Bodies, from the Alkalies, and Earth, and on some Combinations of Hydrogene. Read November 16, 1809.", together with the controversy papers by Davy and Gay-Lussac & Thenard."Mr. Davy having from the commencement of his electro-chemical researches, communicated the several steps of his progress to the Society (The Royal Society), takes the present opportunity of reporting the results of his further inquiries under four principal heads. First, on the nature of the metals of the fixed alkalis. Second, on the nature of Hydrogen and composition of ammonia. Thirdly, on the metals of the earth; and Fourthly he makes a comparison between the antiphlogistic doctrine, and a modified phlogistic hypothesis."(Abstract). He further gives arguments for considering potassium and sodium, which he discovered in 1808, as a element.""Gay-Lussac had a slight rivalry between himself and the creation scientist Sir Humphry Davy. Davy was chemically preparing Potassium and Sodium through an electrical current, and this made Gay-Lussac and Thénard envious of his success. They too decided to perform the same task, but they had no battery at their disposal as Davy had, so they had to form another way to chemically prepare the two elements. In 1808, they used a red-hot iron fused to potash, the water-soluble form of a manufactured salt containing potassium, to perform this task, a method that Davy admitted had its advantageous qualities. Gay-Lussac and Thénard were successful in preparing Potassium, and continued to make a full analysis of its chemical properties, and began to use it for their own experiments. In 1809, Davy performed the same task, using it to reduce Boron in Boracic acid."

Stamps to verso of title-page and verso of plates. Wear to extremities, especially upper part of spine. Internally fine and clean. (Fresnel:) 89-128; 303-328 pp. (Entire volume:) 10, 476 pp. + 3 plates. First German translation of Fresnel’s landmark work “Sur la Lumière" from 1822. Here Fresnel established the scientific basis for the wave theory of light and gave the theoretical framework for explaining, in the context of his theory of the transversal nature of lightwaves, the phenomena of double refraction, refraction, dispersion, polarization, interference, diffraction patterns, diffraction fringes as light spreads around objects, etc. He developed mathematically the hypothesis of the wave nature of light and he demonstrates its conformity with experience. His study of light was a dynamic interplay between theory and observation, between mathematics and experiment. - "From the point of view of method, his investigations extended from the manual operations of the laboratory to the most abstract mathematical analyses. Few physicists since Newton had been so versatile."(Silliman in "Historical Studies in the Physical Sciences", vol. 4, p. 155.). "The wave-thory at this time was still encumbered with difficulties. Diffraction was not satisfactorily explained; for polarization no explanation of any kind was forthcoming; the Huygenian construction appeared to require two different luminiferous media within double refracting bodies; and the universality of that construction had been impugned by Brewster's discovery of biaxial crystals. The upholders of the emission theory, emboldened by the success of Laplace's theory of double refraction, thought the time ripe for their final triunph; and as a step to this, in March 1817 they proposed Diffration as the subject of the Academy's prize for 1818. Their expectation was disappointed; and the successful memoir afforded the first of a series of reverses of which, in the short space of seven years, the corpuscular theory was completely owerthrown. The author was Augustin Fresnel..."(Whittaker "A History of the Theories of Aether & Electricity", vol. 1, p.107 ff.). "This concept of transverse waves met with the greatest hostility from the scientists of the day, who could not imagine an extremely fluid and rarified ether which at the same time possessed the mechanical properties of a rigid body. Even Arago admitted that he could not follow the exuberant engineer in his ideas. ButFresnel was convinced that at last he had the key to many mysteries, and with his model of waves he gave a full clarification of the phenomena of polarization. With insuperable precision he explained a long series of extremely complicated experiments, such as those of chromatic polarization that Arago himself had discovered by chance in 1811, and which the followers of Newton could not explain in spite of all their efforts. Following this line Fresnel reached the synthesis which is his masterpiece....we must recall the final interpretation that he gave of the famous phenomenon of partial reflection by transparent surfaces, that simple phenomenon which until then had puzzled Grimaldi, Newton, and Huygens, and which in Malus's experiments had unexpectedly acquired a special importencee as it had been compared to the great mystery of double refraction."(Ronchi "The Nature of Light", p. 255 ff.).

Stamps to title-page, otherwise and excellent, very nice and clean copy in a very pretty cont. binding. VIII, 348 pp. The uncommon first edition of Michelet's first notable work, "A System of Philosophical Morals". The noticeable German philosopher Karl Ludwig Michelet (1801 - 1893) was left-Hegelian philosopher who defended a political and religious liberalism that tended towards radicalism. He was an important student of Hegel and he was the co-editor of his works. He studied philosophy at the University of Berlin and became doctor here in 1824; in 1829, the year after he published the present work, he became professor of philosophy at the university and remained so until his death. He spent his entire career defending and continuing the doctrines of Hegel. In his "System der philosophischen Moral", he deals with the principles of human actions and examines the ethical theory of the responsibility of these.

Paris, Rue et Hotel Serpente, 1791. 8vo. Contemporary half calf. Gilt spine. In: "Annales de Chimie: ou Recueil de Mémoires Concernant la Chimie et les Arts qui en Dépendent. Par MM. de Morveau, Lavoisier, Monge, Berthollet, De Fourcroy, le Baron de Dietrich, Hassenfratz & Adet." Tome Huitieme. (2),336 pp. The entire volume offered. The paper: pp. 230-308. A few scattered brownspots. Small stamps on verso of titlepage. First appearance of the paper in which the authors records a series of experiments on the combustion of hydrogen, the aim of which was to confirm Lavoisier's large scale experiments on the synthesis of water. They finally proved that water only contains hydrogen and oxygen, and found the approximate ratio of their weights."In May 1790 Séguin read to the Académie des Sciences the report on the larg-scale synthesis of water carried out in Fourcroy’s laboratory by himself, Fourcroy, and Vauquelin. The purpose of this experiment was to establish finally that water is composed only of hydrogen and oxygen and that the weight of water is fully accounted for by the weights of the two gases. They also sought to determine accurately the combining ratio of the components of water, an especially important constant in oxygen chemistry. They found that the ratio hydrogen: oxygen is 2.052:1 by volume and 14.338:85.662 by weight. (The discrepancies from the true figure probably arose from the difficulties of weighing the gases.)"(DSB).Apart from other importent chemical papers by Fourcroy, Seguin, Klaproth etc., the volume contains Joseph Black's famous letter to Lavoisier, where Black gives up his phlogistic theory and accepts the new chemistry, lead by Lavoisier.
