Cf. Darwin, Descent of Man, 108, 217 ff., 590, 591, who is cautious in his statement as to the rule among the quadrumana. Kautsky, "Entstehung der Ehe und Familie," Kosmos, XII, 198 ff., gives some interesting illustrations of marriage among animals; and see Espinas, op. cit., 444 ff.; Atkinson, Primal Law, 219-25.
