Maschka relates a case of a woman, forty-four years of age, who confessed in court se conjunxisse cum cane. Quondam die canis forte saluit inter femora sua et lambit vulvam feminae. Deinde femina inter nuda femora sua animal sumpsit et permulsit abdomen animalis, quoad penis erectus esset. Tum ad sellam nisa, canem ad se pressit et postquam penem inter labia posuit commovit animal ut motiones faceret, usque dum ejaculatio veniret. Rosse reports the case of a young white, unmarried woman in Washington who was surprised in flagrante delicto with a large English mastiff, who in his efforts se solvere a puella caused an injury of such a nature that she died from hemorrhage within an hour. All these cases do not reveal any kind of a perversion. The practices seem to have been due to vice or perversity. The following case, communicated to the author by Dr. C., of Tequisquipan, Mexico, who accidentally entered the patient’s hut while she was kneeling on her bed “in copulatione cum mulo suo,” shows distinctly its pathological nature: The patient, a widow, thirty-six years of age, was married at the age of sixteen and had her first child a year later. Her husband died ten years ago. She had one other child five years ago which died in infancy. She had always been of a passionate nature. Jam undecim annos nata cum viris se conjunxit. Stuprum manu faciebat on and off all her life, especially at the time of menstruation, cum viri ea concumbere nollent. Concarnationes habebat sedecies una nocte, going the rounds of the different nightshifts at the mills. About three years ago she had the first time coitum cum animali. Suus canis erat. Inde sæpe commiscebatur cum canibus. About a year ago, while returning with her burro from a neighboring town, duos canes in conjugio vidit, quod se valde concitavit. Cum mane postmeridianum tempus esset virum celeriter invenire non potuit. Qua re mulum in casam sumpsit et coepit contrectare fascinum, donec emersit. Deinde in grabatum reptavit, posuit muli pedes priores in eo, et ipsa cubitis genibusque nixa est. “Tum femora muli in tergo suo posuit et postquam penem animalis inter labia inseruit; coitum solitum cum animali habuit, in quo ea ipsa motiones fecit celeres aut lentas, secundum necessitatem suam.” She now has the burro trained so that when she lets him enter the hut he commences at once to unsheath antequam potest posituram capere. The examination of the patient showed nothing abnormal in the organs, except an extreme sensitiveness to touch. The mere separation of the labia induced orgasm. During the examination she had four to five orgasms. There can be no doubt that this woman was suffering from nymphomania. Men could not satisfy her increased sexual desire, so she took refuge to animals. FOOTNOTES:
