 and neither drink deliberately nor even graze quietly. In the 

 pasture these ani mals gfraz e badly, run about, annoy the herd, 

 and tear up the earth with horns or hoofs. If the nymphomania 

 is intensely developed the animal becomes very vicious toward 

 surrounding objects, especially strange persons or glistening 

 bodies in bright colors and falls upon them, as we have repeatedly 

 observed, in maniacal fury. In some cases of nymphomania, the 

 affected animals attempt to mount neighboring cows, bulls, oxen, 

 and even persons and continue to ride the former for a long in- 

 terval ; on the other hand, they permit bulls and also other cows 

 to mount them constantly. [The viciousness of nymphomaniac

 the affected cow, which has already become markedly unthrifty, 

 shows an elevated croup, a forward sinking of the anus and vulva, 

 lordosis, stiffness of the loins, associated with an upright direc- 

 tion or knuckling-over of the hind fetlock, " kuhhessige " posi- 

 tion and often a slightly staggering gait. That a nymphomaniac 

 cow may suffer simultaneously from other diseases, such as capped 

 knee, pelvic fractures, foul in the foot, etc., is to be regarded 

 merely as a coincidence and that old, oft recurring cyst forma- 

 tion may lead to an exaggeration of all the symptoms described 

 is readily understood.
