Satyriasis and nymphomania, arising from onanism, are most intense, when the persons affected with it can no longer conceal their feelings, but indulge openly in vile manœuvres. We have already mentioned some remarkable instances of this state. The following may serve as the type of the greatest degree of nymphomania. The patient was a little girl less than three years old, who indulged freely in onanism. Neither caresses, entreaties, threats, nor punishments, could correct her. The child grew, however. But at the sight of any pleasant object, she abandoned herself to her manœuvres. At the period of the crisis, she seemed almost entirely to have lost her sight and hearing. Threats and punishments finally restrained her, while in the presence of her parents; but when alone, she still continued her bad habits. This state resisted all remedies. When married, the legitimate sources of enjoyment took the place of the passionate indulgences to which she had been accustomed from infancy. She finally became pregnant, and died in labor. (_Dict. des Sc. Med._; vol. xxxvi., p. 566.) Onanism is not only a direct cause of satyriasis and of nymphomania; it may leave in the genital organs a certain disposition, which, if cherished, may degenerate into one of these affections. The following case, published by Duprest-Rony, seems to us to be an instance of this:-- A young man, twenty years old, of a strong and almost athletic frame, but who had been enfeebled by onanism, abandoned himself, from the age of fifteen to eighteen years, to this destructive habit. He indulged in this habit even while in the bath, and sometimes to the extent of fifteen times in a day. His constitution was enfeebled; his mind was affected; his memory impaired. In accordance with the advice of some prudent people, this young man renounced this fatal habit. During the next two years, he was perfectly continent. His constitution resumed its vigor; his memory and other mental faculties were restored. His parents now placed him with a merchant. He entered upon his new occupations with zeal and activity; but receiving marks of attachment from the merchant and his wife daily, he imagined that she was in love with him. On his side, the passion was returned. Actuated by the fear of violating the duties of gratitude, and the desire of possessing this lady, who was neither young nor pretty, his situation daily became more embarrassing. Whenever she looked at him, erections took place, and there was a discharge of semen. During the night, he had frequent pollutions. His faculties now became deranged: this derangement supervened after reading the Phedra of Racine. He identified himself so closely with the characters of this piece, that he supposed himself to be Hippolyte, and considered his mistress to be Phedra, and her husband as Theseus. More amorous than Hippolyte, and no less virtuous, he threw himself one day at the feet of Theseus, and said, “Theseus! the crime
