Of homosexually inclined women, some engage in the practice of tribadism, familiar to the ancient world, and recorded by _Martial_ in a satire, in which sexual gratification is obtained by mutual friction of the genital organs, or by penetration of one woman’s clitoris into the vagina of the other; whilst some indulge in the _amor lesbicus_, in which gratification is obtained _lambendo linguâ genitalia_, a very ancient practice indeed, transported from Phœnicia to Greece (where in especial it was indulged in by the women of Lesbos), and later from Syria to Italy, where it was widely diffused among the Romans of the imperial age. _Sappho_, celebrated as the tenth muse, is supposed to have been addicted to the practice of Lesbian love. All such homosexual (female) individuals are, then, endowed with the perverse instinct toward sexual connection with women instead of with men. In such cases, the genitals are usually quite normal; sometimes, however, the woman thus affected is markedly of a male type, being called by _von Krafft-Ebing_ a _gynandrist_, the affection itself being termed _gynandry_; when the woman concerned not only possesses a homosexual impulse, but also in other respects exhibits tendencies properly characteristic of the male sex, she is called _virago_, and the affection is termed _viraginity_. I had under my care such a woman, belonging to the upper circles of society, who had been married sixteen years before, had lived a married life for six years (during which she remained barren), and had then separated from her husband. She was of a very masculine disposition, smoked, gamed, drank like a student, and preferred to wear men’s clothing, and she bestowed her affections on a female companion. Examination of the genital organs disclosed no abnormality beyond a slight vaginal catarrh. Menstruation was regular, and the general appearance showed no departure, with the exception of a slight moustache that shaded the upper lip, from that of a normal feminine beauty. _Mantegazza_ is of opinion that in the case of many unhappy marriages, in which the source of the unhappiness is obscure, the trouble is to be found in the homosexual inclination of the wife. _Martineau_ and _Moll_ report that married women who are homosexually inclined, indulge in sexual intercourse with other women behind their husbands’ back. _Duhousset_, at a meeting of the Anthropological Society at Paris in 1877, related the almost incredible case of a married homosexual woman who, in intercourse with another woman, transferred to the latter her husband’s semen, so as to induce pregnancy.
