Mr. E., twenty-four years of age, decides to leave his country and go to America. While waiting a few days for his boat to clear the port, he spent one evening in a restaurant. After sitting there for some time, he noticed a couple entering the same hostelry. The woman was about thirty years of age, the man about twenty-five her senior. The couple soon left the place. About an hour later the man returned, sat down at the same table where E. was sitting and soon entered into a conversation with him. In the course of their talk, the old man asked E. whether he would like to have female company for the evening. Upon the affirmative answer, the old man took E. to an aristocratic apartment in a distinguished part of the city. There E. met with the young lady he saw entering the restaurant, et cum ea pernoctavit, the old man spending all this time in an adjoining room. The following day the old man prevailed on E. to give up the trip to America for a while and stay with them. E. stood this idle life for six months, but finally his rôle as a commaritus or rather as a fornicator came home to his conscience and he left for America. While he was staying there he learned that the elderly man and the young woman were husband and wife. E. gave the author the assurance that during the entire six months the husband, this he is positively sure, never approached his wife sexually. He left her to E. without manifesting the least trace of jealousy. The only explanation for such a strange phenomenon is that the husband was impotent and that the only way for him to experience at least some pleasure from his wife was by identifying himself with the lover. Such cases represent the extreme degree of mixoscopy. _Erotomania._—The increased sexual desire in hyperaesthesia is not always directed upon the physical gratification. Sometimes it is more of an ideal nature, as in erotomania. Physiological erotomania is often found in individuals of both sexes, especially in young girls, at the time of puberty. Many a youth and maiden are highly erotic, at this period, although, if reared in purity and attended with vigilance, they never think yet of the physical contact.
