From _von Maschka’s_ elaborate account of unnatural offences, in his _Handbook of Forensic Medicine_, we abstract the following passage relating to the female sex: “Lascivious procedures liable under certain circumstances to legal punishment may consist: 1. In handling or other manipulation of the genitals, without actual intercourse. If the genital organs of a female have merely been gently handled, without any more violent manipulations, we shall not, as a rule, either in the case of children or of adults, find any local changes as a result; contrariwise, if the handling has been rough and brutal, if the fingers have been forcibly thrust within the vulval cleft, or if the pudendum has been pulled and rent, we may expect to find excoriations, redness, swelling, laceration of the hymen, or even of the vagina and the perineum. 2. In licking the female genitals (cunnilingere). An analogous process also effected by members of the female sex, whether children or adults, is _irrumare, id est, penem in os arrigere; fellare, id est, vel labiis vel lingua perfricandi atque exsugendi officium penis præstare_. 3. In introduction of the membrum virile into the rectum, either of children or of adults, pæderasty.” That this form of sexual gratification is not infrequently practiced upon women has been pointed out especially by _Parent-Duchatelet_, and is asserted by _von Maschka_ from personal knowledge of cases in which it has occurred. Tribadism and Lesbian love, unnatural vice practiced by two individuals of the female sex, occur, according to _von Maschka’s_ description in the following manner: _a._) By masturbation, either one person gratifying the other by manipulation, or mutual masturbation. In a case of this kind recorded by _Tardieu_, a wife still young repeatedly, and by day as well as by night, introduced her finger deeply into the vagina or the rectum of her little girl, moving it about there sometimes for as long as an hour. According to the child’s account, the mother herself at these times was in a condition of excitement, no doubt sexual, which she gratified in this manner. In another case, several older girls engaged with their own fingers and tongues in lascivious practices with the genital organs of a little girl of seven. According to _Krausold_, among female prisoners such “forbidden friendships” are extremely common, formed for the purpose of mutual masturbation, and in connection with which the bitterest jealousy and the most ardent love are exhibited. _b._) With the assistance of an enlarged clitoris, with which one woman performs the sexual act by introducing the organ within the vagina of another. In France in the nineteenth century a woman is said to have lived whose genital organs were so formed that, on the one hand, as a woman she played the passive part in intercourse with men, and, on the other hand, was able to give sexual gratification to women by assuming the active part of the male.
