Various, Popular Science Monthly (1884)
“ The youth came, and thus was opened the career of the illustrious Georges Cuvier. He and Geoffroy became fast friends, and together composed five memoirs, of which one, on the classification of mammalia, contained the theory of the subordination of characters, fundamental to Cuvier's system. In a memoir on the Makis, or Madagascar monkeys, published a year afterward by Geoffroy alone, appears the principle of unity of composition, to which the author afterward related all comparative anatomy. ”
