Pp. 39-104 and 1 engraved plate showing some of the apparatus used in his electrochemical researches. Fine and clean. First appearance of this importent paper in the history of chemistry.In this paper "he tried one hypthesis after another to account for the ultimate constitution of matter and for the nature of acidity. He believed that the simplicity and harmony of nature demanded that there be very few ultimately distinct forms of matter; itis ironical that one who held that that the chemical elements were probably all compounds should have been such a frequent discoverer of new elements. Davy was particularlu confused by ammonium amalgam, a pasty material produced when ammonium salts are electrolyzed with a mercury cathode..."(DSB III, p. 602).- Partington IV, pp. 49 ff.

London, 1807. 1st Edition. Hardcover. Very Good. 1st Edition. Hardcover. 4to - over 9¾ - 12" tall. Journal extract from: Philosophical Transactions of the Royal Society of London for the Year 1806, Vol. 97, Part One, published 1807. Slim 4to, pp. 1-56. Volume title, plus engraved plate at rear, some spotting, recent blue buckram gilt. ---- Sparrow 52, PMM 255 (remark) - Davy found that when he passed electrical current through some substances, these substances decomposed, (a process later called electrolysis). Davy must have known of Lavoisier's suggestion that the alkali earths were s of unknown metals. At first, he tried to separate the metals by electrolyzing aqueous solutions of the alkalis, but this yielded only hydrogen gas. He then tried passing current through molten compounds, and his persistence was rewarded when he was able to separate globules of pure metal by this means. His first successes came in 1807 with the separation of potassium from molten potash and of sodium from common salt. He described potassium as particles which, when thrown into water, "skimmed about excitedly with a hissing sound, and soon burned with a lovely lavender light." Dr. John Davy, Humphry's brother, said that Humphry "danced around and was delirious with joy" at his discovery. These results were presented in his second Bakerian lecture of November, 1807.

1809. (London, W. Bulmer and Co., 1809). 4to. No wrappers as extracted from "Philosophical Transactions" 1809 - Part I. Pp. 39-104 and 1 engraved plate showing some of the apparatus used in his electrochemical researches. Fine and clean. First printing of a historical paper in chemistry, in which Davy announced his isolation, by electrochemistry, of Calcium, Barium, Strontium and Magnesium, and claiming that boracic acid is metallic in nature and proposing the name "boracium". He further discusses chemical theory."The objects which principally occupied Mr. Davy's attention in the present lecture are, the elements of ammonia; the nature of sulphur; the nature of phosphorus, the states of carbonaceous principle in plumbago, charcoal, and diamond; the analysis of boracic acid; the analysis of fluoric acid; with a series of numerous experiments on muriatic acid."

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…

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…

Description:
1807. London, Philosophical Transactions, 1807. 4to. Bound to style in recent plain blue wrappers. Offprint, with the separate printed title-page, from "Philosophical Transactions" 1807 - Part I. With author's presentation to title-page: "From the Author". Occassional brownspotting throughout and a small tear, not affecting text, to lower margin of B4. (2), 56 pp. + 1 plate. The exceedingly rare offprint, inscribed presentation copy, of Davy’s milestone paper in which he shows that electricity is capable of decomposing the most stable elements. The paper was central to any chemical affinity theory in the first half of the nineteenth century and Berzelius, one of the founders of modern chemistry, considered it "one of the best memoirs which has ever enriched the theory of chemistry”. Davy early concluded that the production of electricity in simple electrolytic cells resulted from chemical action and that chemical combination occurred between substances of opposite charge. He therefore reasoned…
