A. Reverdin, "Epingles à Cheveux dans la Vessie," Revue Médicale de la Suisse Romande, January 20, 1888. His cases are fully recorded, and his paper is an able and interesting contribution to this by-way of sexual psychology. The first case was a school-master's wife, aged 22, who confessed in her husband's presence, without embarrassment or hesitation, that the manœuvre was habitual, learned from a school-companion, and continued after marriage. The second was a single woman of 42, a curé's servant, who attempted to elude confession, but on leaving the doctor's house remarked to the house-maid, "Never go to bed without taking out your hair-pins; accidents happen so easily." The third was an English girl of 17 who finally acknowledged that she had lost two hair-pins in this way. The fourth was a child of 12, driven by the pain to confess that the practice had become a habit with her.
"One of my patients," remarks Dr. R. T. Morris, of New York, (Transactions of the American Association of Obstetricians, for 1892, Philadelphia, vol. v), "who is a devout church-member, had never allowed herself to entertain sexual thoughts referring to men, but she masturbated every morning, when standing before the mirror, by rubbing against a key in the bureau-drawer. A man never excited her passions, but the sight of a key in any bureau-drawer aroused erotic desires."
