Moreover, women previously moral, when affected with senile dementia, may manifest similar conditions of great sexual excitement (nymphomania, furor uterinus). It may be seen from a reading of Schopenhauer,[37] that, as a result of senile dementia, the abnormally excited and perverse instinct may be directed exclusively to persons of the same sex (_v. infra_). The manner of the satisfaction is here passive pederasty, or, as I ascertained in the following case, mutual masturbation:— Case 2. Mr. X., aged 80, of high social position, from a family having hereditary taint. He was always very sensual and a cynic, of uncontrollable temper, and, according to his own confession, as a young man, preferred masturbation to coitus. However, he never showed signs of contrary sexual instinct, and kept mistresses, raising a child by one. At the age of forty-eight he married, out of inclination, and begat six children, and never gave his wife cause for complaint. I could obtain but an incomplete history of his family. It was certain that his brother was suspected of love for men, and that a nephew became insane as a result of excessive masturbation.

The aged patient awaits the hour of rendezvous in true sexual excitement. He sends his family away, that he may be with his favorite undisturbed, and remains shut up with him for hours; and when the doors are opened again, he is found lying on the bed exhausted. Besides this object of his passion, the patient had intercourse episodically with other servants. It is certain that he enticed them, asked them for kisses, exhibited himself, allowed manipulation ad genitalia, and practiced mutual masturbation. By these practices absolute demoralization was brought about. The family was powerless; for any opposition caused violent outbreaks of anger and even threats against his relatives. The patient was completely without appreciation of his perverse sexual acts; and therefore the only course left to the afflicted family was to remove all authority from his hands and place him in an asylum. No erotic inclination toward the opposite sex was observed, though the patient occupied a
