1815réf. 45715London W. Bulmer and Co. 1815. 4to. No wrappers as extracted from "Philosophical Transactions" 1815 - Part II. Pp. 203-213 a. pp. 214-219. First appearance of two importent papers by davy. In the second paper offered he relates his discovery of chlorine dioxyd."By explosion over mercury he found that 2 vols. give from 2.7 to 2.9 of gas and this would probably be 3 vols. if no chlorine had been absorbed by the mercury. This gas contains 2 vols. of oxygen and the remainder chlorine hence the compound consists of 'two in volume of oxygen and one of chlorine condensed into the space of two volumes' ClO2. He found it to explode at about 100 deg. with more viollence than euchlorine."Partington III p. 57.Together with ROBERT PORRETT "Further analytical experiments relative to the constitution of the prussic; of the ferruretted chyazic and of the sulphuretted chyazic acids; and of their salts; together with the application of the atomic theory to the analysis of these bodies." pp. 220-230 a. 2 tables one folding. unknown
1810réf. 42219London W. Bulmer and Co. 1810. 4to. No wrappers as extracted from "Philosophical Transactions" 1810 - Part I. Pp. 16-74 and 2 engraved plates showing Davy's electrochemical apparatus for decomposing substances. The plates dampstained. Text fine and clean. First appearence of this historical chemical paper Davy' fifth Bakerian Lecture in which he announced his discovery of hydrogen telluride."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."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 lectures." - Wheeler Gift: 2518. unknown
1808réf. 42218London W. Bulmer and Co. 1808. 4to. No wrappers as extracted from "Philosophical Transactions" 1808 - Part I. Pp. 1-44. First printing 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.
