Nymphomania 187 



is uniform, soft-elastic, more seldom tense-elastic, and then dur- 

 ing the existence of estrum. 



From the above facts and the post mortem findings yet to be 

 related, it is indicated that cystic and cysto-fibrous degeneration 

 of the ovaries almost uniformly lead to a non-infectious chronic 

 catarrhal endometritis and only seldom to chronic muco-purulent 

 endometritis or to chronic purulent endometritis, which makes it 

 self evident that an impregnated ovum could not become attached 

 to the uterine wall to undergo development into a fetus. Rela- 

 tions analogous to those existing between cystic and cysto-fibrous 

 ovarial degeneration and the sinking of the sacro-sciatic liga- 

 ments hold good also between the former and the enlargement of 

 the uterus. 



In bilateral cystic degeneration of the ovaries there exists no 

 definite relation between the size of the cysts and the increased 

 circumference of the uterus, which is usually symmetric, rarely 

 asymmetric. In cases of unilateral formation of cysts the 

 entire uterus- is frequently uniformly larger and longer or, on 

 the other hand, the enlargement may be confined to the cornu 

 leading to the affected ovary. 



Finally, it must be conceded that, as a general rule, the symp- 

 toms of nymphomania are referable to the ovaries themselves, 

 which are the chief and almost exclusive seat of the anatomo- 

 pathologic changes, and that diseases of the uterus and vagina, 

 without involving the ovaries, can only very rarely lead to symp- 

 toms of nymphomania. On the other hand we have observed, 

 and verified our diagnosis by post mortem, examinations, that in 

 both uncastrated and castrated cows, cysts in the broad liga- 

 ments and in the oviducts, and hydatids in the oviducts or am- 

 puUse can cause well marked nymphomania. 



As abnormalities of the ovaries which we have definitely recog- 

 nized and verified in connection with nymphomania in cows we 

 may relate : 



1. The formation of cysts or vesicles of the follicles — hyper- 

 trophy of the ovisacs. 



According to Zschokke three genetic forms of these may be 

 differentiated : 



a. Those which spring from the Graafian follicles and are to 

 be designated as hydrops foUiculorum.
