and stamping with the feet. In one instance in our clinic, the 

 mania was almost exclusively exhibited when the mare was 

 alone in the stall. Watched from a distance, she would stamp 

 her feet and kick the sides of the box stall in which she was 

 confined. In her maniacal kicking she was utterly indiflferent 

 of the consequences to herself and would frequently and repeat- 

 edly kick one leg viciously with the other. Her eyes were wild 

 and staring and her whole appearance and behavior one of 

 violent insanity. If her owner or other person entered the stall 

 she became calm, began eating or fondled the person with her 

 nose and appeared in every way rational and docile. Turned in 

 a paddock, she behaved normally. Hitched in the usual manner 

 to a single wagon, she behaved perfectly. The duration of the 

 mania and its intensity had increased for some months until the 

 degree we have described had been reached and the attacks con- 

 tinued during 7-10 days. Ovariotomy was followed 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 discharge from 

 the vulva. 



Urination is frequent, while the clitoris is erected and frequently 

 protruded between the vulvar lips. The irritability of the vulva 

 and vulvo-anal region is markedly increased ancl the animal fre- 

 quently violently resents the handling of the.se parts. This is 

 especially true, in many cases, of the tail, the animal resenting 

 the raising of it in order to apply the crupper or remove it. 

 While driving, should the patient either accidentally or inten- 

 tionally get her tail over the reins, she 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 projection of the 

 clitoris, making her unfit for driving purposes simply from 

 repulsiveness. 



In most cases, however, the patient is unreliable or dangerous 

 and cannot be depended upon in moments of emergency. During 

 the periods of nymphomania she is very liable to be unsteady in
