The author proposes a new hypothesis for cancer, believing that it occurs only in species which reproduce themselves by amphimixis and not in those in which reproduction is parthenogenic, thus placing the responsibility on the combination of preexisting hereditary elements. A large portion of the discussion is based on a survey of the literature, chiefly drawn from paleontology and embryology. One illustration even is a reproduction of the famous buffalo from the walls of the caves of Altamira, presumably done some 30,000 years ago. Just how profitable such theoretical studies may be depends on the possibility of an experimental attack and this does not seem feasible from the author's presentation. A bibliography of thirty-four references is appended.
