One day, while returning from school, she was addressed, on the street, by a man whom she had never seen before and who asked her whether she did not know him, her cousin from X. He said that he was just going to see her parents, his uncle and aunt. On the way he took her to a candy-store and bought her candy. When leaving the store he told her that he had forgotten to take along a present for her parents which he left in his room, and they both went to fetch it. Upon entering his room, he locked the door and abused her. Upon hearing the story the indignation of the medical authorities of the hospital was beyond all description. The police was immediately notified to hunt for the criminal. A representative from the district attorney’s office (Untersuchungsrichter) and a detective soon appeared at the hospital to get more particulars from the child. The officers of the court seemed to have a much better experience in the examination of such cases than the doctors, for when they left the child’s room her story read quite differently. The girl’s father had a workshop in the business section of the city, while the family lived in another part. When leaving school in the afternoon the child used often to visit the father’s shop and take home the dishes he took along in the morning. One day, while in the shop with her father, he took her in the back room of the shop and abused her. Under threat of death these immoral attacks were often repeated for months afterwards, until one day the unnatural father noticed that his child conceptavit ab eo. He then made up the story with the cousin which the child first told the hospital authorities. The father was arrested, tried, and sentenced to ten years’ hard labor. This case shows how low the sufferers of hyperaesthesia may fall. The man was not drunk when he made the repeated attacks upon his child. The excuse of the defective separation of the living quarters is also missing, nor does here exist the cause of “faute de mieux,” as it is sometimes found in widowers living with their adult daughters in incestuous unions. The man here had a healthy wife. Hence it is nothing else but a case of sexual hyperaesthesia pure and simple of a weak-minded individual. Incest is oftener found in men than in women, yet there are cases recorded where women were the seducers. Legrand describes the case of a girl, fifteen years of age, who seduced her brother to all manner actionum voluptificarum in se. His other case is that of a woman of thirty-six who, although married, indulged in abusing her brother, a boy of eighteen. The same woman was otherwise abnormal, suffering from the anomaly known as exhibitionism, which is seldom found in women, except among the insane in asylums. She often exposed her breasts from the window to attract men. In another case of the same author, a mother, thirty-nine years of age, practised incest with her own son and ab eo comprehendit.
