FOOTNOTES:
[1] In the American Journal of Public Health for July, 1913, Dr. John S. Fulton, Director General of the XV International Congress on Hygiene and Demography, criticized severely the extremely radical statistics that were presented on charts at the sex-hygiene exhibit of the Congress, and were later published in Wilson's "Education of the Young in Sex-hygiene."
[2] There is danger in quoting to young men the estimates as to prevalence of social diseases and, therefore, of promiscuity. Fear of consequences will not control one who is led to believe that he is doing what most men do. (See Parkinson in Educational Review, Jan. 1911, pp. 44-46.)
[3] Many writers have discounted the value of warnings involved in sex-instruction concerning social disease (see especially Cabot's papers referred to in § 46, and Parkinson in Educational Review, January, 1911).
[4] Louise Creighton, in her excellent little book on "The Social Disease and How to Fight It" (Longmans), has well presented the problems of social impurity from woman's point of view.
Dr. W.S. Hall, in "Life's Problems," has given in a few pages the necessary protective knowledge.

[8] As an illustration of this fact, out of 558 Pittsburgh professional prostitutes, 406 had never had children. Of the 152 who were mothers, only 24 had two or more children.
