Paul-Emile Lecoq de Boisbaudran's Sur un nouveau metal, le gallium, published in the Comptes Rendus de l'Academie des Sciences in 1875, is the primary scientific announcement of the discovery of the element gallium. Its authority is that of the discoverer's own report, published in the proceedings of the French Academy of Sciences, and its significance rests on the element's properties matching what Dmitri Mendeleev had predicted in 1871 for a then undiscovered element he called eka-aluminium. It is a primary chemistry paper documenting a discovery, not a history of the periodic table's development, which needs a separate source.
