To quote Dante à propos of the illicit amours of a pintail and a wild duck may shock the learned, but the aptness of the quotation proves once more the essential identity of the animal and human organisms. III. The Family amongst Animals.
If the study of the modes of sexual union amongst animals is not useless to the sociologist, that of the animal family is at least quite as interesting. This latter confirms the inductions of theorists relative to the primitive form of the human family. The animal family is especially maternal. The female of birds, immediately she has laid her eggs, experiences a sort of intoxication; to sit becomes for her an imperious need, which completely transforms her moral nature.
