Näcke states that, in his experience, while masturbation is, apparently, commoner in insane men than in insane women, masturbation repeated several times a day is much commoner in the women. (P. Näcke, "Die Sexuellen Perversitäten in der Irrenanstalt," _Psychiatrische Bladen_, 1899, No. 2.) Great excesses in masturbation seem also to be commoner among women who may be said to be sane than among men. Thus, Bloch (_New Orleans Medical Journal_, 1896) records the case of a young married woman of 25, of bad heredity, who had suffered from almost life-long sexual hyperesthesia, and would masturbate fourteen times daily during the menstrual periods. With regard to excesses in coitus the case may be mentioned of a country girl of 17, living in a rural district in North Carolina where prostitution was unknown, who would cohabit with men almost openly. On one Sunday she went to a secluded school-house and let three or four men wear themselves out cohabiting with her. On another occasion, at night, in a field, she allowed anyone who would to perform the sexual act, and 25 men and boys then had intercourse with her. When seen she was much prostrated and with a tendency to spasm, but quite rational. Subsequently she married and attacks of this nature became rare. Mr. Lawson made an "attested statement" of what he had observed among the Marquesan women. "He mentions one case in which he heard a parcel of boys next morning count over and _name_ 103 men who during the night had intercourse with _one_ woman." (_Medico-Chirurgical Review_, 1871, vol. ii, p. 360, apparently quoting Chevers.) This statement seems open to question, but, if reliable, would furnish a case which must be unique.
