Since the patient explained that, for reasons of family and business, it was necessary for him to marry, it was impossible to avoid this delicate question. Fortunately, the patient limited his inquiries to the question as to his virility as a husband; and it was necessary to reply that he was virile, and that he would probably be so in conjugal intercourse with the wife of his choice,—at least, if she were to be in mental sympathy with him; besides, that he could at all times improve his power by exercising his imagination in the right direction. The main thing was to strengthen the sexual inclination for the opposite sex, which was defective, but not absolutely wanting. This could be done by avoiding and opposing all homo-sexual feelings and impulses, possibly with the help of the artificial inhibitory influences of hypnotic suggestion (removal of homo-sexual desires by suggestion); by the excitation and exercise of normal sexual desires and impulses; by complete abstinence from masturbation, and eradication of the remnants of the neurasthenic condition of the nervous system by means of hydrotherapy, and possibly general faradization. I am indebted to a physician, aged thirty, for the following autobiography, which in another respect is noteworthy:— Case 108. _Mental Hermaphroditism; Abortive Contrary Sexual Instinct._—“In my ancestry I am somewhat predisposed hereditarily. My grandfather on my father’s side was a high-liver and a speculator. My father was a man of character, but for more than thirty years he has suffered with folie circulaire, without, however, being much hindered by it in business. My mother, like her father before her, suffers with stenocardiac attacks. My mother’s father and brother are said to have been sexually hyperæsthetic. My only sister, about nine years older than myself, was twice subject to attacks of eclampsia, and during puberty was religiously exalted, and probably also sexually hyperæsthetic. During many years she had to suffer with a severe hysterical neurosis, but she is now completely well.
