The broad assertion that the natives are entirely ignorant of the existence of physiological impregnation may be laid down quite safely and correctly. . . . There seems to be no doubt that if we are at all justified in speaking of certain "primitive" conditions of mind, the ignorance in question is such a primitive condition, and its prevalence among the Melanesians of New Guinea seems to indicate that it is a condition lasting right into much higher stages of development than it would seem possible to assume on the basis of Australian material only.1
