when masturbation takes place we are not entitled to admit exhibitionism, (_Untersuchungen über die Libido Sexualis_, bd. i, p. 661), but now accepts exhibitionism with masturbation ("Perverse Sexualempfindung," _Krankheiten und Ehe_). The act of exhibition itself gratifies the sexual impulse, and usually it suffices to replace both tumescence and detumescence. A fairly typical case, recorded by Krafft-Ebing, is that of a German factory worker of 37, a good, sober and intelligent workman. His parents were healthy, but one of his mother's and also one of his father's sisters were insane; some of his relatives are eccentric in religion. He has a languishing expression and a smile of self-complacency. He never had any severe illness, but has always been eccentric and imaginative, much absorbed in romances (such as Dumas's novels) and fond of identifying himself with their heroes. No signs of epilepsy. In youth moderate masturbation, later moderate coitus. He lives a retired life, but is fond of elegant dress and of ornament. Though not a drinker, he sometimes makes himself a kind of punch which has a sexually exciting effect on him. The impulse to exhibitionism has only developed in recent years. When the impulse is upon him he becomes hot, his heart beats violently, the blood rushes to his head, and he is oblivious of everything around him that is not connected with his own act. Afterwards he regards himself as a fool and makes vain resolutions never to repeat the act. In exhibition the penis is only half erect and ejaculation never occurs. (He is only capable of coitus with a woman who shows great attraction to him.) He is satisfied with self-exhibition, and believes that he thus gives pleasure to the woman, since he himself receives pleasure in contemplating a woman's sexual parts. His erotic dreams are of self-exhibition to young and voluptuous women. He had been previously punished for an offense of this kind; medico-legal opinion now recognized the incriminated man's psychopathic condition. (Krafft-Ebing, _Op. cit._, pp. 492-494.) Trochon has reported the case of a married man of 33, a worker in a factory, who for several years had exhibited himself at intervals to shop-girls, etc., in a state of erection, but without speaking or making other advances. He was a hard-working, honest, sober man of quiet habits, a good father to his family and happy at home. He showed not the slightest sign of insanity. But he was taciturn, melancholic and nervous; a sister was an idiot. He was arrested, but on the report of the experts that he committed these acts from a morbid impulse he could not control he was released. (Trochon, _Archives de l'Anthropologie Criminelle_, 1888, p. 256.)
