‎Athembarkeit des sauerstoffhaltigen Stickgas"" aus einem Briefe H.Davy's an Will. Nicholson. (+) Nachricht von einigen merkwürdigen Versuchen Davy's. (Aus einem Briefe Humphry Davy's an Will. Nicholson).‎

‎Halle, Rengerschen Buchhandlung, 1799, 1800. Without wrappers extracted from ""Annalen der Physik. Herausgegeben von Ludwig Wilhelm Gilbert"", Bd. 2. p. 483 (one page). and Bd. 6, pp. 105-115. Some scattered brownspots.‎

‎First German translation of Davy's announcement (the announcement on 1 page) of his discovery of the unusual, anaesthetic, effects of nitrous oxide which, on being inhaled, gave rise to a giddy, intoxicated feeling. On announcing his discovery he says, that he will publish a paper discribing the experiments with the gas, later. This is the paper offered here, also in the first German version. Both the announcement and the paper were issued in the ""Annalen"" the same year as they appeared in Nicholson's Journal.The gas was first synthesized by English natural philosopher and chemist Joseph Priestley in 1772, who called it phlogisticated nitrous air.""Following Priestley's discovery, Humphry Davy of the Pneumatic Institute in Bristol, England, experimented with the physiological properties of the gas, such as its effects upon respiration. He even administered the gas to visitors to the institute, and after watching the amusing effects on people who inhaled it, coined the term 'laughing gas'! Davy even noted the anaesthetic effects of the gas: ""As nitrous oxide in its extensive operation appears capable of destroying physical pain, it may probably be used with advantage during surgical operations in which no great effusion of blood takes place"".(Wikipedia).""Davy discovered the anaesthetic properties of nitrous oxide and suggested its use during surgiical operations, a suggestion which was not turned to useful account until 1844.""(Garrison & Morton, 5646, not mentioning the announcing of its discovery in 1799).‎

‎London, Colburn, 1831, un fort volume grand in 4 relié en demi-soie noire, dos orné de filets dorés (reliure moderne), 1 PORTRAIT DE Humphry DAVY, 15pp., 548pp., 1 planche dépliante hors texte représentant une note manuscrite de Humphry DAVY‎

‎---- EDITION ORIGINALE DE FORMAT IN 4 ---- BEL EXEMPLAIRE ---- RARE FIRST EDITION IN QUARTO FORMAT ---- "At the age of fifteen DAVY was apprenticed to an apothecary surgeon and two years later began to teach himself chemistry. Around that time he met James Watt's son, Gregory, with whom he conducted a correspondence. He was appointed professor of chemistry at the Royal Institution in 1802 and spent most of his career there. He was elected to the Royal Society in 1803 and was its president from 1820 to 1827. His first researches were into the nature of heat, which he believed to be motion, at the same time believing light to be a form of matter".

‎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.‎

He further gives arguments for considering potassium and sodium, which he discovered in 1808, as a element.""""Gay-Lussac had a slight rivalry between himself and the creation scientist Sir Humphry Davy. Davy was chemically preparing Potassium and Sodium through an electrical current, and this made Gay-Lussac and Thénard envious of his success. They too decided to perform the same task, but they had no battery at their disposal as Davy had, so they had to form another way to chemically prepare the two elements. In 1808, they used a red-hot iron fused to potash, the water-soluble form of a manufactured salt containing potassium, to perform this task, a method that Davy admitted had its advantageous qualities. Gay-Lussac and Thénard were successful in preparing Potassium, and continued to make a full analysis of its chemical properties, and began to use it for their own experiments. In 1809, Davy performed the same task, using it to reduce Boron in Boracic acid.""‎

It is unstable and explodes on heating to give chlorine and oxygen. Davy here suggested the name 'chlorine', from a greek work for green, because of the greenish colour of the gas.Thorpe said of this first paper ""As a piece of induction, the memoir is a model of its kind, and as an exercise in ""the scientific use of ofthe imagination"" it has few equals.""Davy's researches on chlorine are of an importence with those on the alkali metals. Chlorine, first discovered by Scheele, was regarded by him as ""dephlogisticated muriatic acid"". As phlogistion was perfectly synonymous with hydrogen to Scheele, this view was essentially correct. Lavoisier, however, chiefly occupied with phenomena of combustion, assumed that chlorine was an oxide of an unknown ""radical"". avy performed many experiments endeavouring to confirm the presenceof oxygen and finally concluded that chlorine was an element.""(Leicester & Klickstein ""A Source Book in Chemistry"", p. 243 ff).‎

‎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.

‎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 description and the first announcement of the invention of the Mine Safety Lamp, the so-called ""Davy-Lamp"" together with his further remarks on the functioning of this lamp. The papers are miliestones of applied chemistry.""In 1815 he (Davy) invented the Davy lamp, in which an open flame is surrounded by a cylinder of metallic gauze. Oxygen can get through the gauze and feed the flame. The heat of the flame, however, is dissipated by the metal and explosive gases outside the lamp and not ignited. For the first time, miners were reasonably safe from explosion. In 1818 Davy was made a Baronet for his service to industry.""

‎First appearance of these importent papers in the history of chemistry in which Davy announces his proofs of the elementary nature of clorine, describing the preparation, physical and chemical properties of a new gas, which he called 'euchlorine'. It is unstable and explodes on heating to give chlorine and oxygen. Davy here suggested the name 'chlorine', from a greek work for green, because of the greenish colour of the gas.Thorpe said of this first paper ""As a piece of induction, the memoir is a model of its kind, and as an exercise in ""the scientific use of ofthe imagination"" it has few equals.""Davy's researches on chlorine are of an importence comparable with those on the alkali metals. Chlorine, first discovered by Scheele, was regarded by him as a *dephlogisticated muriatic acid"". As phlogiston was practically synonymous with with hydrogen to Scheele, this view was essentialy correct. Lavoisier, however, chiefly occupied with phenomena of combustion, assumed that chlorien was an oxide of an unknown ""radical"". Davy performed many experiments endeavouring to confirm the presence of oxygen and finally concluded that chlorine was an element.""(A Source Book in Chemistry 1400-1900, p. 244).‎
