defective women commonly become prostitutes. The feeble-minded, as distinguished from idiots, are an exceptionally fecund class, mostly of illegitimate children, and a terrible proportion of their offspring are born mentally deficient. All these experts were in agreement that mentally defective girls are in great danger of becoming immoral, hence prostitutes. _DEGENERACY, ITS CAUSES, SIGNS AND RESULTS. Eugene S. Talbot, M.D. Walter Scott, Ltd., London; Chas. Scribner’s Sons, N. Y. 1898._ Pauline Tarnowsky in her study “Etudes Anthropometriques sur les Prostituées” finds that in Russia prostitution is crime in women taking the line of least resistance. She concludes from her researches, which mine tend to verify, that the prostitute as a rule is a degenerate being, the subject of an arrest of development, tainted with a morbid heredity, and presenting stigmata of physical and mental degeneracy fully in consonance with her imperfect evolution. C. Andronico of Messina, Italy, arrived some time previously at the same conclusions as those of Tarnowsky. _FEEBLE-MINDEDNESS, ITS CAUSES AND CONSEQUENCES. Henry Herbert Goddard, Director of the Research Laboratory of the Training School at Vineland, N. J., for Feeble-minded Boys and Girls. McMillan Co., 1914._ Among the different causes for the social evil feeble-mindedness has been suggested, but nowhere has it been given the prominence that is due it. Anyone who understands feeble-mindedness, especially the moron, cannot expect anything less than that great numbers of these girls will fall into the life of prostitution. As to the actual statistics on this subject we have almost none. One very significant record comes from Geneva, Illinois, made by Dr. Bridgman. She found that of 104 girls in the Reformatory who were committed for an immoral life 97% were feeble-minded. This does not by any means indicate that 97% of prostitutes are feeble-minded, because it is only natural to expect that the feeble-minded ones would be the ones to be caught and sent to an institution. These figures, nevertheless, give us some idea of the prevalence of feeble-mindedness in this traffic. Many competent judges estimate that 50% of prostitutes are feeble-minded. Pages 14–15. The 327 cases here presented constitute a unitary group. They have not been selected. They are of all ages and grades of defect. Page 7. Our 327 families naturally fall into six fundamental groups, as follows: 4—Accident Group, 57; 5—No Cause, 8; 6—Unclassifiable, 27. Pages 47–48. The following table gives an idea of the fecundity of these groups of women.
