With regard to acquired sexual inversion, he dwells upon the influence of bad example, the power of imitation, fashion, corrupt literature, curiosity in persons jaded with normal excesses. Extraordinary details are given concerning the state of schools in Russia (pp. 63-65); and a particular case is mentioned, in which Tarnowsky himself identified twenty-nine passive pæderasts, between the ages of nine and fifteen, in a single school. He had been called in to pronounce upon the causes of an outbreak of syphilis among the pupils. Interesting information is also communicated regarding the prevalence of abnormal vice in St. Petersburg, where it appears that bath-men, cab-drivers, care-takers of houses, and artisans are particularly in request (pp. 98-101). The Russian people show no repugnance for what they call "gentlemen's tricks." Tarnowsky calls attention to ships, garrisons, prisons, as milieux well calculated for the development of this vice, when it had once been introduced by some one tainted with it. His view about nations like the Greeks, the Persians, and the Afghans is that, through imitation, fashion, and social toleration, it has become endemic. But all the sorts of abnormality included under the title of acquired Tarnowsky regards as criminal. The individual ought, he thinks, to be punished by the law. He naturally includes under this category of acquired perversion the vices of old debauchees. At this point, however, his classification becomes confused; for he shows how senile tendencies to sodomitic passion are frequently the symptom of approaching brain disease, to which the reason and the constitution of the patient will succumb. French physicians call this "la pédérastie des ramollis."
Returning to what Tarnowsky says about the inborn species of sexual inversion, I may call attention to an admirable description of the type in general (pp. 11-15) I think, however, that he lays too great stress upon the passivity of the emotions in these persons, their effeminacy of press, habits, inclinations. He is clearly speaking from large experience. So it must be supposed that he has not come across frequent instances of men who feel, look, and act like men, the only difference between them and normal males being that they love their own sex. In describing a second degree of the aberration (pp. 16, 17), he still accentuates effeminacy in dress and habits beyond the point which general observation would justify. Careful study of the cases adduced in Krafft-Ebing's "Psychopathia" supplies a just measure for the criticism of Tarnowsky upon this head. From them we learn that effeminacy of physique and habit is by no means a distinctive mark of the born pæderast. Next it may be noticed that Tarnowsky believes even innate and hereditary tendencies can be modified and overcome by proper moral, and physique discipline in youth, and that the subjects of them will even be brought to marry in some cases (pp. 17, 18).
