Only within the past few years have the general phenomena
of intersexuality been cleared up to any considerable
extent—naturally on the basis of the secretory
explanation of sex. This secretory or endocrine
idea has also given us an entirely new view of sex
differences. These are best discussed as functional
rather than as structural. To correlate this
material, we must next give a rude sketch of the quantitative
theory of sex.
