First French version of Davy's "The Bakerian Lecture for 1809. On some new Electrochemical Researches, on various Objects, particularly the metallic Bodies, from the Alkalies, and Earth, and on some Combinations of Hydrogene. Read November 16, 1809.", together with the controversy papers by Davy and Gay-Lussac & Thenard.

"Mr. Davy having from the commencement of his electro-chemical researches, communicated the several steps of his progress to the Society (The Royal Society), takes the present opportunity of reporting the results of his further inquiries under four principal heads. 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."
