‎First edition of this seminal and highly influential paper on electron diffraction. Today the paper is regarded as one of the most important in the entire journal of Nature, and it led directly to Davisson receiving the Nobel Prize in physics in 1937. It advanced understanding of physics at the quantum level and led to inventions such as the electron microscope. Davisson and Germer's confirmation of the de Broglie hypothesis if today known as the Davisson-Germer experiment.""Davisson's investigations on the scattering of electrons entered a new phase when, in April 1925, his taget was heavily oxidized by an accidental explosion of a liquid-air bottle. He cleaned the target by prolonged heating and then found the distribution-inangle of the secondary electrons completely changed, new showing a strong dependence on crystal direction. Prior to the accident the target had consisted of many tiny crystals, but heating converted it to several large crystals. Davisson and L. H. Germer, who had replaced Kunsman before the accident, at once began bombarding targets of single crystals. [...] When Davisson returned from England, he and Germer began a systematic research for some sort of interference phenomenon, and in January 1927 they observed electron beams resulting from diffraction by a single crystal of nickle. The results were in good agreement with de Broglie's prediction. For his confirmation of electron waves Davisson shared the Nobel Prize in physics in 1937 with G. P. Thomson.""

‎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 that electrolysis, the interactions of electric currents with chemical compounds, offered the most likely means of decomposing all substances to their elements. “These views were explained in 1806 in his lecture “On Some Chemical Agencies of Electricity,” for which, despite the fact that England and France were at war, he received the Napoleon Prize from the Institut de France (1807). This work led directly to the isolation of sodium and potassium from their compounds (1807) and of the alkaline-earth metals magnesium, calcium, strontium, and barium from their compounds (1808).” (Britannica). ""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.

‎First German edition of ONE OF THE MOST IMPORTENT CONTRIBUTIONS EVER MADE TO CHEMICAL SCIENCE, as Davy here outlined a theory of mass action, forcast the use of electricity in atomic disintegration and announced the isolation by electrolytic methods of two new elements, sodium and potassium. He used the most powerful electric battery of the time, a voltaic pile, invented 1800 by Volta.""Humphrey Davy...was among the first to investigate the decomposition of water. In 1806 he delivered a Bakerian Lecture (the paper offered here in the German version) before the Royal Society of London ""On some chemical agencies of electricity"" (1807), which pointed out several fallacies in the theory of electrolysis. Davy's experiments on the chemical effects of electrical currents on substances, causing their decomposition, led to his discovery of several new elements: potassium (1807), sodium (1807), barium (1808), calcium (1808), and boron (1808)"" (Milestone of Science No. 52) - Davy's first Bakerian Lecture won a Prize from Napoleon, even though France and England were at War. - Partington vol. IV pp. 42 ff. - PMM No 255 (note). - Parkinson, Breakthroughs: 1807 C.The issue contains also Heron de Villefosse: ""Nivellement des Harzgebirges mit dem Barometer"", pp. 49-114 a. 1 engraved folded map.Berzelius called Davy's 1806 Bakerian Lecture On Some Chemical Agencies of Electricity ""one of the best memoirs which has ever enriched the theory of chemistry."" This paper was central to any chemical affinity theory in the first half of the nineteenth century.‎

‎First German edition of this landmark paper in chemistry, in which Davy shows that electricity is capable of decomposing the most stable chemical combinations. He decomposes 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.(A Source Book in Chemistry p. 243). - Wheeler Gift: 2514.‎

‎First appearance of an importent paper in which Davy's states, that the voltaic pile only works under certain conditions, and only when the conducting substance between the plates is capable of oxydating the zink. The principle discovered here guided Davy in designing new types of pile, with elements chosen from the whole variety of known metals.‎

‎First edition of this importent work which is considered the first text book dealing with the application of chemistry to agriculture. It is the ""first serious attempt to apply chemistry to agriculture (which) remained a standard work until displaced by Justus Liebig's publications a generation later"" (DSB).""An importent book that introduced the era of scientific farming and the use of ""chemically balanced"" fertilizers.... Davy, the first to use the term 'agricultural chemistry', was also the first to point out that agricultural chemistry is concerned with only a limited number of elements. The most complete list of elements that had yet appeared is given (pp. 39-44), including chlorine, which Davy had proven an element. Davy here recognizes the importence of soil analysis and the measurement of its physical properties. It was well received, and several English and American editions appeared, as well as translations in foreign languages."" (Roy G. Neville Historical Chemical Library Vol. I, pp. 333-334).Duveen, pp. 644-45.‎
