His other works include Cours de minéralogie (1884, 3rd ed., 1899), La Formation des combustibles minéraux (1886), Le Niveau de la mer et ses variations (1886), Les Tremblements de terre (1887), La Géologie en chemin de fer (1888), Précis de minéralogie (1888), Le Siècle du fer (1890), Les Anciens Glaciers (1893), Leçons de géographie physique (1896), Notions générales sur l’écorce terrestre (1897), Le Globe terrestre (1899), and Science et apologétique (1905). With Achille Delesse he was for many years editor of the Révue de géologie and contributed to the Extraits de géologie, and he joined with A. Potier in the geological surveys undertaken in connexion with the Channel Tunnel proposals. He died in Paris on the 5th of May 1908.
