_Incest._—Another anomaly which must be attributed to hyperaesthesia sexualis is incest. Incest, as such, has nothing pathological in its essence. In the early history of human marriage incest was the rule. It was practised even in historic times. Abraham was married to his sister, according to the Bible. Cimon of Athens was also married to his sister. In the royal house of the Ptolomei it was common for brothers to marry their sisters to avoid a division of the empire. Cleopatra, the evil star of Marc Anthony, was married to her brother. But these few examples were the exceptions, generally, for the last three thousand years incest has been considered an abomination in the eyes of God and men. Its practice was constantly inveighed against by Church and State. It has, therefore, because of these constant suggestions, become the second nature of man to abhor such practices. Only an exaggerated sexual desire, coupled with the absence of understanding for laws and morals, could nowadays lead to incest in any civilized country. Even in the crowded tenements where all members of the family of both sexes live and sleep in one room, incest is still a great rarity, and when such a case happens, it deeply wounds the feelings of the entire community. Such incestuous immoral attacks are, as a rule, made by low, brutal men in a state of intoxication or by those who suffer from weak-mindedness, by epileptics and by paranoiacs. Hence in every case of incest, we are justified in assuming that the seducer is suffering from sexual hyperaesthesia. An asylum and castration may be a more appropriate treatment for such a patient than the treatment in prison. The following case came under the author’s observation while he was house-physician in the Woman’s Hospital of a well-known European university: A mother brought her twelve-year-old girl to the skin department of the general hospital to be treated for a certain rash the child was suffering from, for some time. The rash was diagnosed there as pityriasis versicolor, and the child was recommended to go to the Woman’s Hospital for treatment. At the examination here it was found that the twelve-year-old child was six months pregnant. Being too small and delicate, even for her age, to give birth to a full-term child, it was decided to induce premature labor. Before the operation, the child was asked for the name of the man who was responsible for her predicament, and the following was her version of the accident:
