the girl was _virgo intacta_, he declined and she went away. A fortnight or so later he received a letter from her in the country, making no reference to what had passed, but giving an account of her work with her Sunday-school class. He did not reply, and then came a curt note asking him to return her letter. My friend feels sure she was devoted to auto-erotic performances, but, having become attracted to him, came to the conclusion she would like to try normal intercourse." Wolbarst, studying the prevalence of gonorrhea among boys in New York (especially, it would appear, in quarters where the foreign-born elements--mainly Russian Jew and south Italian--are large), states: "In my study of this subject there have been observed 3 cases of gonorrheal urethritis, in boys aged, respectively, 4, 10, and 12 years, which were acquired in the usual manner, from girls ranging between 10 and 12 years of age. In each case, according to the story told by the victim, the girl made the first advances, and in I case, that of the 4-year-old boy, the act was consummated in the form of an assault, by a girl 12 years old, in which the child was threatened with injury unless he performed his part." (A.L. Wolbarst, _Journal of the American Medical Association_, Sept. 28, 1901.) In a further series of cases (_Medical Record_, Oct. 29, 1910) Wolbarst obtained similar results, though he recognizes also the frequency of precocious sexuality in the young boys themselves. Gibb states, concerning assaults on children by women: "It is undeniably true that they occur much more frequently than is generally supposed, although but few of the cases are brought to public notice, owing to the difficulty of proving the charge." (W.T. Gibb, article "Indecent Assaults upon Children," in A. McLane Hamilton's _System of Legal Medicine_, vol. i, p. 651.) Gibb's opinion carries weight, since he is medical adviser for the New York Society for the Protection of Children, and compelled to sift the evidence carefully in such cases.
