5. Edema of the Ovaries is described by Zschokke as occur- 

 ring, in his experience, in old, nymphomaniac cows. The ovaries 

 are somewhat enlarged and contain a few small follicles but no 

 corpora lutea. Upon incision, the dropsical fluid is easily pressed 

 out from the cut surface. The cut surface is grayish red in color 

 and shows the usual characters of edema, which is confined to 

 the gland itself. 



The abnormality is to be differentiated chiefly from cystic ova- 

 ries and persistent corpora lutea. Examining the glands care- 

 fully per rectum, the touch reveals the somewhat large, soft, 

 yielding ovary in contrast to the firm fluctuating and sharply 

 defined cysts of cystic degeneration or the prominently enlarged 

 and comparatively firm, non-fluctuating persistent yellow body. 



The dependent sterility is usually beyond remedy and, in case 

 of nymphomania, ovariotomy should be performed in order to 

 cure the vice and permit the cow to be fatted for the butcher.
