790 Diseases of the Genital Organs 



frequently and repeatedly kick one leg viciously with the 

 other. Her eyes were wild and staring and her whole ap- 

 pearance and behavior one of violent insanity. If her owner 

 or other person entered the stall she became calm, began eat- 

 ing or fondled the person with her nose, and appeared in 

 every way rational and docile. Turned in a paddock she be- 

 haved normally. Hitched in the usual manner to a single 

 wagon, she behaved perfectly. The duration of the periods 

 of mania and its intensity had increased for some months 

 until the degree described had been reached and the attacks 

 continued during seven to ten days. Ovariotomy was fol- 

 lowed by complete and permanent disappearance of the 

 mania. 



The distinctively sexual symptoms noted consist chiefly 

 of tumefaction of the vulva, injection of the vulvar mucosa, 

 and increased secretion of mucus, with some mucous dis- 

 charge from the vulva. 



Urination is frequent, the clitoris is erected and fre- 

 quently protruded between the vulvar lips. The irritability 

 of the vulva and vulvo-anal region is markedly increased 

 and the animal frequently resents violently the handling of 

 these parts. This is especially true, in many cases, of the 

 tail; the animal resents the raising of it in order to apply 

 the crupper or remove it. While driving, should the patient 

 either accidentally or intentionally get her tail over the 

 reins, she often grips them violently, kicks viciously, may 

 turn abruptly and upset or break the vehicle, or run away. 



In some cases the patient is perfectly docile and the only 

 signs of disease consist of abnormally frequent urination 

 with repeated opening and closing of the vulva and the pro- 

 jection of the clitoris, making her unfit for driving purposes 

 simply from repulsiveness. 



In most cases, however, the patient is unreliable or dan- 

 gerous and can not be depended upon in moments of emer- 

 gency. During the periods of nymphomania she is very 

 liable to be unsteady in draft work and may at any momenl 

 balk and tax the patience of the driver very greatly. 



Periodical at first, the vices of nymphomania, such as
