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.""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." </em> unknown
186244063Leipzig Johann Ambrosius Barth 1862. Without wrappers as issued in "Annalen der Physik und Chemie. Hrsg. von J.C. Poggendorff" Vierte Reihe Bd. 27 117 Stück Zwei No. 10. The entire issue offered. Titlepage to vol. 27. Pp. 193-352 a. 1 engraved plate. Ångströms paper: pp. 290-302. <br/><br/><em>First appearance in German of Ångström's famous paper in which he announced the discovery of hydrogen in the atmosphere of the sun and in which he also confirmed the probable existence of of other elements there. The paper appeared in "Oefversigt af K. Vet. Acad. Förhandl." in 1861. The German paper here is expanded. At the same time it was translated into English and publishe as "On the Fraunhofer Lines Visible in the Solar Spectrum".Ångström was one of the early formulators of the science of modern spectroscopy; he wrote extensively on terrestrial magnetism the conduction of heat and especially spectroscopy. He published a monumental map of the normal solar spectrum that expressed the length of light waves in units of one ten-millionth of a millimeter a unit of length now known as the angstrom. He discovered that hydrogen is present in the sun's atmosphere and he was the first to examine the spectrum of the aurora borealis. </em> unknown

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. </em> unknown
