“_History._――In the hot weather of August, the writer was called 15 miles to consult with Dr. A., the family physician of Mr. T. About three weeks prior to this, Miss T. had suddenly exhibited paroxysms of uncontrollable desire for coition. When any young gentleman chanced to call upon the family, she would elevate her apparel under her arms, approach and attempt an embrace in the most lascivious manner, until forced to desist by the interference of the overpowering strength of the persons present. At first these scenes were at intervals, with intervening times of great dejection, gloominess and silence. The father being of rather a superstitious nature, thought her ‘possessed of the devil,’ and resorted to repeated and severe flagellations without effecting any perceptible reform. During the last week her excitement had been almost continuous, and she had been confined to and locked in her room. It may well be supposed that the case had excited the entire neighborhood to wonder and amazement, and in some of the more thoughtful, deep sympathy, and through their advice the physician was called. “Examination with a glass speculum showed an irritating fluid oozing from the os uteri; the whole surface of the vagina, the nymphæ clitoris and the vulva were suffering from active congestion. Exalted general sensation was apparent, and the slightest touch of the internal labia or clitoris produced the most exquisite amorous excitement――an uncontrollable mania. “_Case II._――Was called to see Mrs. F., of this city, September last, age 30, a grass widow by third marriage. Found her in violent hysterical spasms, with usual accompanying symptoms. Her aunt, with whom she was then visiting, gave the following: “_History of the Case._――For some time past she had exhibited lasciviousness; had to be kept under surveillance; to-day the aunt had ‘been out shopping;’ on coming home she found her niece in a sequestered place with exposed nudity quite shocking, and using persistent artifice to effect coition with a canine Newfoundlander. The aunt so rashly interposed, that the niece ‘went into alarming and persistent spasms.’” Dr. Potter further says that examination showed this case to be one of nymphomania, relying upon the turgescence of the clitoris and nymphæ and ichorous discharge from the os uteri as diagnostic. It may be remarked that such turgescence not uncommonly produces an exalted erotic desire which is analogous to turgescence of the urethra in the male, manifested in gonorrhœal priapism.
