Nymphomania 183 



Out of the 120 nymphomaniac cows of our statistics, 47 ex- 

 hibited more or less evident changes in the vulva, consisting of 

 an edematous swelling of variable intensity, exceptionally greater 

 og one side, and an elongation and widening of the vulvar com- 

 missure. In 12 cases there was a slight active hyperaemia evi- 

 denced by a redness of the labias of the vulva, referable to a 

 pressure upon the vasodilators in the ovaries. In a few cases, where 

 prolapse of the vagina coexisted, there was an evident wrinkling, 

 either chiefly in the superior half or involving the entire circum- 

 ference of the vulvar lips, as well as invagination, that is, an 

 entropium of the vulvar lips. 



It is of symptomatic significance that, in heifers suffering from 

 dumb estrum (stillochsigkeit ), the variable edematous swelling 

 of the vulva, under some conditions, constitutes the only notable 

 external symptom which, omitting the abnormal findings in the 

 ovaries, can not at all be explained. 



Among our 120 cases there existed in 42 a very variable vaginal 

 discharge. In 30 ca.ses, this was slight, vitreous and slimy ; in the 

 other 12, on the contrary, muco-purulent or, when it had to do 

 with old purulent metritis or pyometra, wholly purulent. 

 In a combination of nymphomania with prolapse of the vagina 

 or of the vaginal portion of the uterus, there was found a muco- 

 purulent discharge mixed with fecal particles, which were later 

 drawn into the vagina by the spontaneous reduction of the pro- 

 lapse when the cow assumed the standing position. 



If vaginal discharge exists, the hairs of the vulvar tuft are 

 matted and the ventral surface of the tail, next to the vulva, 

 soiled. 



The vaginal mucosa, in J5 % of the ca.ses of nymphomania, is 

 reddened, injected and swollen, the latter especially marked 

 when prolapse of the vagina or vaginal portion of the uterus 

 coexists. Very often one finds the symptoms of chronic infectious 

 nodular vaginitis (nodular or granular venereal diseases of the 

 cow ), such as a yellowish hue of the vaginal mucosa in those parts 

 no longer inflamed, blanched vesicles and nodules no longer sur- 

 rounded by inflamed areas, either grouped in one part or dissem- 

 inated over the entire vaginal mucosa. More seldom, the mucosa 

 is superficially eroded as a result of therapeutic efforts. 



A comparatively frequent finding is retention cysts of the glands 

 of Bartholini, varying from the .size of a hazelnut to a fi.st and,
