The frequency of homosexual practices among prostitutes is a fact of some interest, and calls for special explanation, for, at the first glance, it seems in opposition to all that we know concerning the exciting causes of homosexuality. Regarding the fact there can be no question.[155] It has been noted by all who are acquainted with the lives of prostitutes, though opinion may differ as to its frequency. In Berlin, Moll was told in well-informed quarters, the proportion of prostitutes with Lesbian tendencies is about 25 per cent. This was almost the proportion at Paris many years ago, according to Parent-Duchâtelet; today, according to Chevalier, it is larger; and Bourneville believes that 75 per cent, of the inmates of the Parisian venereal hospitals have practised homosexuality. Hammer in Germany has found among 66 prostitutes that 41 were homosexual.[156] Hirschfeld thinks that inverted women are specially prone to become prostitutes.[157] Eulenburg believes, on the other hand, that the conditions of their life favor homosexuality among prostitutes; "a homosexual union seems to them higher, purer, more innocent, and more ideal."[158] There is, however, no fundamental contradiction between these two views; they are probably both right. In London, so far as my inquiries extend, homosexuality among prostitutes is very much less prevalent, and in a well-marked form is confined to a comparatively small section. I am indebted to a friend for the following note: "From my experience of the Parisian prostitute, I gather that Lesbianism in Paris is extremely prevalent; indeed, one might almost say normal. In particular, most of the chahut-dancers of the Moulin-Rouge, Casino de Paris, and the other public balls are notorious for going in couples, and, for the most part, they prefer not to be separated, even in their most professional moments with the other sex. In London the thing is, naturally, much less obvious, and, I think, much less prevalent; but it is certainly not infrequent. A certain number of well-known prostitutes are known for their tendencies in this direction, which do not, however, interfere in any marked way with the ordinary details of their profession. I do not personally know of a single prostitute who is exclusively Lesbian; I have heard vaguely that there are one or two such anomalies. But I have heard a swell _cocotte_ at the Corinthian announce to the whole room that she was going home with a girl; and no one doubted the statement. Her name, indeed, was generally coupled with that of a fifth-rate actress. Another woman of the same kind has a little clientele of women who buy her photographs in Burlington Arcade. In the lower ranks of the profession all this is much less common. One often finds women who have simply never heard of such a thing; they know of it in regard to men, but not in regard to women. And they are, for the most part, quite horrified at the notion, which they consider part and parcel of 'French
