VAGINAL OVARIOTOMY OF THE 



MARE 



(CHARLIER'S METHOD) 



Not infrequently it becomes necessary to castrate 

 mares for the correction of ailments involving the 

 ovaries. The principal disturbance caused by degen- 

 erative changes in the ovaries, is nymphomania, which 

 so often causes viciousness that mares thus affected are 

 very unsatisfactory in service at the time of the estral 

 period, displaying various undesirable traits such as 

 kicking, biting and striking, and many of them are 

 line grippers. Maniacal symptoms always predominate 

 in these mares and their frequent stopping to eject 

 small amounts of urine and the protrusion to view of 

 the erected clitoris, makes them repulsive as well as 

 harmful. 



When consulted, veterinarians should urge the un- 

 sexing of such animals as it is the only sensible naode 

 of correcting this condition. Other corrective opera- 

 tions have been performed, resulting in recovery in 

 some eases, but they are not to be recommended. Am-
