Small stamps on verso of titlepage.In: "Annales de Chimie ou Recueil de Mémoires concernant la Chemie" Tome 70. 336 pp. Entire volume offered. Davy's paper: pp. 189-254. First edition in French the first English 1808 of this importent historical paper in chemistry in which Davy shows that electricity is capable of decomposing some alkalies isolating two new substances and discovering potassium and sodium. Neville in his Historical Chemical Library vol. I p.340 writes about this paper "ONE OF THE GREAT CLASSIC RESEARCHES IN CHEMISTRY in which Davy announced in this his second Bakterian lecture the isloation of metallic potassium and sodium by the electrolytic decomposition of their fused oxides.""He Davy began his own electrical experiments.The results were spectacular. On October 6 1807 the current passing through molten potash liberated a metal which Davy called potassium. The little globules of shining metal tore the water molecule apart as it eagerly recombined with oxygen and the liberated hydrogen burst into lavender flame. Davy danced about in a delirium of joy. A week later he isolated sodium from soda."Asimow. The paper offered here describes these discoveries."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 papers are the French translations of his papers published in Abhandl. d. königl. Akad. d. Wissenscchaften in Berlin in 1861 and 1862.In the course of his preparatory work in the autumn of 1859 Kirchhoff made an unexpected observation. It had long been known that the dark D lines noticed in the solar spectrum by Fraunhofer 1814 coincided with the yellow lines emitted by flames containing sodium.Kirchhoff's unexpected discovery was that if the intensity of the solar spectrum increased above a certain limit the dark D lines were made much darker by the interrposition of the sodium flame. He instantly felt that he had got hold of "something fundamental" even though he was at a loss to suggest an explanation. On the day following the surprising observation Kirchhoff found the the correct interpretation which wass soon confirmed by new experiments: a substance capable of emittiing a certain spectral line has a strong absorptive power for the same line.The dark D lines in the solar spectrum could accordingly be ascribed to absorption by a solar atmosphere containing sodium. Immense prospects thus opened up of ascertaining the chemical composition of the sun and other stars from the study of their optical spectra. A few more weeks sufficed for Kirchhoff to elaborate a quantitative theory of the relationship between emissive and absorptive poweer."DSB VII pp. 381-82.PMM 278 b. - Barchas 1169-70 - Sparrow 117 - Horbli 59 - Dibner 153 the note. hardcover

Entire volume offerd. Faradays papers: pp. 149-189 Sixth series pp. 301-331 a. 481-520 Seventh series. Internally clean and fine printed on good paper. First appearance in German - prepared by Faraday himself for publication in Annalen - of 2 historical papers in chemistry and physiscs in which Faraday in the first detects a new recombination-effect in electrolysis and in the second we have the MILESTONE PAPER in which Faraday announces the discoveries of further laws of electrochemistry stating the general relations of electricity to chemistry and introducing new terms with precise meanings. The first part of the paper introduces his new terminology giving the words a limited and precise meaning. These words devised with the assistance of William Whewell are now familiar to all chemists electrode anode cathode ion anion and cation. He also introduces the "Volta-electrometer" and arrives at the "Law of electro-chemical equivalents". The paper offered is one of Farday's most famous papers."Another section of the paper is devoted to a closer examination of the law of constant electrochemical action with respect to water and to the development of a gas electrometer to measure quantities of electricity. Faraday's "Volta-electrometer" provided the first practical means for the quantitative measurement of electricity." Source Book in Chemistry p. 280-81.The Sixth series: "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. hardcover
