After about 1880, he produced several elementary textbooks of scientific instruction and also various publications on educational and allied subjects. Widely used in French schools for decades as the basis for scientific education, his book "La Deuxième année d'enseignement scientifique" (34th edition: Armand Colin, 1896) claimed that "European whites" are far superior and more intelligent than blacks, people from Asian, and Native Americans, among others.
