Oxygenated muriatic acid is not decomposed by charcoal, and it might be supposed from this fact and those which are communicated in this memoir, that this gas is a simple body. He was a co-discoverer of the element boron. His last publication on aqua regia a mixture of nitric and hydrochloric acids that dissolves gold or platinum came out the year before his death in Gay-Lussac made two balloon ascensions inattaining on the second a height of about 7, m 23, ftto test the variation of the earth's magnetic field and the composition of the atmosphere at varying altitudes. In conclusion, "the alchemists were right. On 12 December an article appeared in Le Moniteur in which Gay-Lussac expressed his view that iodine was probably an element.
As early as Gay-Lussac had discussed the optimum temperature for the production of sulfuric acid in the lead chamber process.

In Gay-Lussac's own words:. From this fact he drew the conclusion that the molecules of these two alums possess the same form. Jean Baptiste Perrin French. In he introduced a method of determining the vapor densities of liquids, and in demonstrated that wood soaked in borax is inflammable. The history of earlier contributions by wikipedians is accessible to researchers here: This law helped in a more complete understanding of a similar law announced by John Daltoncalled the law of multiple proportions, which governed the combining weights of an element that formed more than one compound with another element.
