We give descriptions of a few of the most famous or interesting instances of hermaphroditism. Pare speaks of a woman who, besides a vulva, from which she menstruated, had a penis, but without prepuce or signs of erectility. Haller alludes to several cases in which prolonged clitorides have been the cause of the anomaly. In commenting on this form of hermaphroditism Albucasiusus describes a necessary operation for the removal of the clitoris. Columbus relates the history of an Ethiopian woman who was evidently a spurious female hermaphrodite. The poor wretch entreated him to cut off her penis, an enlarged clitoris, which she said was an intolerable hindrance to her in coitus. De Graff and Riolan describe similar cases. There is an old record of a similar creature, supposing herself to be a male, who took a wife, but previously having had connection with a man, the outcome of which was pregnancy, was shortly after marriage delivered of a daughter. There is an account of a person in Germany who, for the first thirty years of life, was regarded as feminine, and being of loose morals became a mother. At a certain period she began to feel a change in her sexual inclinations; she married and became the father of a family. This is doubtless a distortion of the facts of the case of Catherine or Charles Hoffman, born in 1824, and who was considered a female until the age of forty. At puberty she had the instincts of a woman, and cohabitated with a male lover for twenty years. Her breasts were well formed and she menstruated at nineteen. At the age of forty-six her sexual desires changed, and she attempted coitus as a man, with such evident satisfaction that she married a woman soon afterward. Fitch speaks of a house-servant with masculine features and movements, aged twenty-eight, and 5 feet and 9 inches tall, who was arrested by the police for violating the laws governing prostitution. On examination, well-developed male and female organs of generation were found. The labia majora were normal and flattened on the anterior surface. The labia minora and hymen were absent. The vagina was spacious and the woman had a profuse leukorrhea. She stated that several years previously she gave birth to a normal child. In place of a clitoris she had a penis which, in erection, measured 5 1/4 inches long and 3 5/8 inches in circumference. The glans penis and the urethra were perfectly formed. The scrotum contained two testicles, each about an inch long; the mons veneris was sparsely covered with straight, black hair. She claimed functional ability with both sets of genitalia, and said she experienced equal sexual gratification with either. Semen issued from the penis, and every three weeks she had scanty menstruation, which lasted but two days.
