In estimating the tendency of prostitutes to display congenital physical anomalies, the crudest and most obvious test, though not a precise or satisfactory one, is the general impression produced by the face. In France, when nearly 1000 prostitutes were divided into five groups from the point of view of their looks, only from seven to fourteen per cent, were found to belong to the first group, or that of those who could be said to possess youth and beauty (Jeannel, _De la Prostitution Publique_, 1860, p. 168). Woods Hutchinson, again, judging from an extensive acquaintance with London, Paris, Vienna, New York, Philadelphia, and Chicago, asserts that a handsome or even attractive-looking prostitute, is rare, and that the general average of beauty is lower than in any other class of women. "Whatever other evils," he remarks, "the fatal power of beauty may be responsible for, it has nothing to do with prostitution" (Woods Hutchinson, "The Economics of Prostitution," _American Gynæcological and Obstetric Journal_, September, 1895). It must, of course, be borne in mind that these estimates are liable to be vitiated through being based chiefly on the inspection of women who most obviously belong to the class of prostitutes and have already been coarsened by their profession. If we may conclude--and the fact is probably undisputed--that beautiful, agreeable, and harmoniously formed faces are rare rather than common among prostitutes, we may certainly say that minute examination will reveal a large number of physical abnormalities. One of the earliest important physical investigations of prostitutes was that of Dr. Pauline Tarnowsky in Russia (first published in the _Vratch_ in 1887, and afterwards as _Etudes anthropométriques sur les Prostituées et les Voleuses_). She examined fifty St. Petersburg prostitutes who had been inmates of a brothel for not less than two years, and also fifty peasant women of, so far as possible, the same age and mental development. She found that (1) the prostitute showed shorter anterior-posterior and transverse diameters of skull; (2) a proportion equal to eighty-four per cent. showed various signs of physical degeneration (irregular skull, asymmetry of face, anomalies of hard palate, teeth, ears, etc.). This tendency to anomaly among the prostitutes was to some extent explained when it was found that about four-fifths of them had parents who were habitual drunkards, and nearly one-fifth were the last survivors of large families; such families have been often produced by degenerate parents.
