 dealers and finally finds her way into some inhuman hands, 

 where she succumbs to brutal work. 



Examined macroscopically, the ovaries are usually large 

 and contain one to several cysts, varying in size from V^-2

In other extremely bad cases of nymphomania there are 

 found small, atrophied, fibrous ovaries, very hard and dense,

The examination of the ovaries of the mare is to be made
