First printing of Davy's last Bakerian Lecture.""Davy repeats his theory of 1806 (the classic work on electrochemistry) and describes experiments with a galvanometer on currents from metals, etc. in alkali sulphide solutions, and various types of combinations. If two pieces of copper are introduced one after another into a sulphide solution a current is produced"" he explains this as due to the couple: clean copper/copper sulphide on copper, in the same solution. A similar observation, with two pieces of tin in a hydrocloric acid, mentioned by Davy, had been made by....G.O. Ritter...After some time Davy noticed, the polarity is reversed, owing to the reducing action of hydrogen on the oxide or sulphide first formed.""(Partington vol. IV:p. 72.).""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.""
"DAVY, HUMPHREY. - THE DETONATING EXPERIMENT THAT DAMAGED DAVY'S EYE.

First appearance of this importent historical paper in which Davy describes how he produced Nitrogen Chloride.""In September 1812 Davy heard from Paris of a compound of 'gaz zote et de chlore...."", The discoverer and method of preparation were not stated, and Davy found no notice of it in the French literature. n a paper read on 5 November ....(the paper offered) he described its preparation by the action of chlorine on cooled solutions of ammonia, nitrate of ammonia, and oxalate of ammonia, and some of its explosive properties. He was seriously injured in the eye by an explosion.""(Partington IV, p. 57-58).This explosion induced Davy to hire Faraday as a co-worker.Together with J.F.W.HERSCHEL ""On a remarkable Application of Cote's Theorem. Communcated by by W. Herschel. Read November 12, 1812."" Pp. 8-26 and 1 engraved plate.
On the magnetic phenomena produced by Electricity" in a Letter.... to W.H. Wollaston. Read November 16, 1820.
(London, W. Bulmer and W. Nicol, 1821). 4to. No wrappers as extracted from ""Philosophical Transactions"" 1821 - Part I. Pp. 7-19. Faint offsetting to first page, otherwise fine, broad-margined.
A very interesting and early paper on electromagnetism where Davy only 4 months after Oersted's fundamental discovery of the magnetic effects of the electric curent, makes some of the same experiments (and new) with Volta's pile and with the Leyden Battery. In two long footnotes Davy describes the history of the discoveries of electromagnetic phenomena.""In a foot-note, the author refers to Romagnosi's observations made at Trent in 1802that an insulated wire connected with the pole of a battery deflects a magnwetic needle. Mojon of Genoa is quoted as having rendered a steel needle magnetic by placing it for a long time in a voltaic circuit.""(Weaver Cat.: 2548). - Ronalds Cat.,p. 29.

Firts appearance of the paper which describes Davy's attempt to unroll the papyri scrolls of Herculaneum by using chlorine to decompose the gummy matter holding them together. His attempts were not very successfull.
DAVY, HUMPHREY. - THE RELATION BETWEEN TEMPERATURE AND CONDUCTIVITY DISCOVERED.
Reference : 43173

Farther researches on the magnetic phaenomena produced by electricity" with some new experiments on the properties of electrified bodies in their relations to conducting powers and temperature. ReadJuly 5, 1821.

First printing of an importent paper in which Davy announces his discovery that the conductivity of metals varies inversely with temperature. This discovery receives a practical application half a century later when William Siemens uses it to invent the platinum-resistance thermonmeter to measure temperature. - Parkinson ""Breakthroughs"", 1821 P a. 1971 P.

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.
