ABSTRACT
Until comparatively recently it was thought improper to devote any study to the sexual characteristics of human beings; pruriency went so far as to set the phenomena of sex outside the scope of legitimate investigation, and men who gave thought and study to this subject were looked on askance and with suspicion, and their work was often submitted to ignorant and prejudiced moral censors, who, by their unfair actions, added to the obloquy under which this subject rested.
