explanation of original contrary sexual instinct. He started with the actual bi-sexuality shown by the fœtus anatomically up to a certain age. While normally the organs which attain complete development exclusively condition and determine the sexual type, and the influence of the opposite organs, which remain rudimentary, is nil, it is conceivable that, under the influence of a factor inimical to the normal development of the brain (hereditary taint, etc.), these rudimentary organs likewise exercise an influence which, under certain circumstances, may be even greater than that of the fully developed organs which determine the external sexual type.
In a similar manner, Kiernan (Medical Standard, 1888) and G. Frank Lydston (Phila. Med. and Surg. Reporter, 1888) attempt to explain a part of the cases of congenital sexual paranoia. Magnan, too (Ann. méd. psychol., 1885, p. 458), writes, in all earnestness, of the brain of a woman in the body of a man, and vice versâ.[1]
The attempted explanations of congenital urnings are not less superficial; for instance, that of Ulrichs, who, in his “Memnon,” 1868, speaks of an “anima muliebris virili corpore inclusa (virili corpori innata),” and thus tries to explain the congenital origin and the female character of his abnormal sexual instinct. The idea of the patient, the subject of Case 124, is original. He supposes that when his father begat him he thought to beget a girl, but, instead of a girl, a boy resulted. One of the strangest explanations of congenital contrary sexual feeling is made by Mantegazza (op. cit., p. 106, 1886).
According to this author, in such individuals there exist anatomical anomalies which, by an error of Nature, consist in a distribution to the rectum of the nerves intended for the genitals; so that only in this situation the lustful sensation is aroused which otherwise results from stimulation of the genitals. But how does this author, in other ways so acute, explain the great majority of cases, where pederasty is abhorred by those affected with contrary sexual feeling? Besides, Nature
- ↑ This supposition is overthrown by the result of the post-mortem of my case (118), where the brain-weight was 1150 grammes, and of Case 130, where it was 1175 grammes.
