I first obtained this account of the subject from Namwana Guya'u and Piribomatu, the former an amateur and the latter a professional sorcerer; both were intelligent men and both, in virtue of their profession, were interested in human anatomy and physiology. Thus it represents the highest development of Trobriand knowledge and theory. I obtained similar statements in other parts of the island, and in their main outline—such as the sexual functions of the kidneys, the great importance of the eyes and the olfactory sense, and the strict parallel between male and female sexuality—all were in agreement.
