During it he had the most lively feelings of pleasure. During his stay at the clinic, a remission of the paranoia occurred, and, at the same time, a marked improvement of the neurasthenia. Then the feelings and ideas due to a developing metamorphosis sexualis disappeared. A more advanced case of eviration, on the way to a transformatio sexus paranoica, is the following:— Case 101. Franz St., aged 33; school-teacher; single; probably of tainted family; always neuropathic; emotional, timid, intolerant of alcohol; began to masturbate at eighteen. At thirty there were manifestations of neurasthenia sexualis (pollutions with consequent fatigue, which at last began to occur during the day; pain in the region of the sacral plexus, etc.). Gradually, spinal irritation, pressure in the head, and cerebral neurasthenia were added. Since the beginning of 1885 the patient had given up coitus, in which he no longer experienced pleasurable feeling. He masturbated frequently. In 1888 he began to have delusions of suspicion. He noticed that he was avoided, and that he had unpleasant odors about him (olfactory hallucinations). In this way he explained the altered attitude of people, and their sneezing, coughing, etc. He smelled corpses and foul urine. He recognized the cause of his bad smells in inward pollutions. He recognized these in a feeling he had as if a fluid flowed up from the symphysis toward the breast. Patient soon left the clinic. In 1889 he was again received in an advanced stage of paranoia masturbatoria persecutoria (delusions of physical persecution). In the beginning of May, 1889, the patient attracted notice, in that he was cross when he was addressed as “mister.” He protested against it, because he was a woman. Voices told him this. He noticed that his breasts were growing. Some weeks before, others had touched him in a sensual manner. He heard it said that he was a whore. Of late, dreams of pregnancy. He dreamed that, as a woman, he indulged in coitus. He felt the immissio penis, and, during the hallucinatory act, also a feeling of ejaculation. Head straight; facial form long and narrow; parietal eminences prominent; genitals normally developed. The following case, observed in the asylum at Illenau, is a pertinent example of lasting delusional alteration of sexual consciousness:—
