Nymphomania 179 



14 times with irregular estruni ; 



59 times with nymphomania. 



In 31 cases estrum failed to occur at all, or occurred but 

 rarely and was very slight. 



In 13 cases the sinking of the ligaments was slight. 



In 36 " " " " " moderate. 



In 63 " " " " " severe. 



The 8 cases of nymphomania, without sinking of the ligaments, 

 occurred wholly in vigorous cows, in high condition, partly in 

 animals yielding a heavy flow of milk. The group included 4 

 cows with bilateral ovarian cysts as large as hazelnuts ; one cow 

 which showed irregular estrum and, in addition to a cyst as large 

 as hickory nut in the right ovary, exhibited a chronic catarrhal 

 metritis; another cow which had a cyst as large as a hen's egg 

 and a corpus leutum in the right ovary ; another showing in the 

 right ovary, a cyst of the size of a hen's egg, in the left a small 

 yellow body, and, in addition to these, a slight catarrhal endome- 

 tritis, and in the last cow we found in the right ovary a cy.st as 

 large as a hickory nut. 



The failure of the ligaments to sink when ovarial cysts exist 

 depends, apparently, on the one hand, upon the slight individ- 

 ual susceptibility, and on the other, upon the evidently vigorous 

 constitution of the patient. 



As to the relation of the sinking of the sciatic ligaments to the 

 presence of ovarial cysts, our statistics revealed the following : 



In the 112 cases of sinking of the broad ligaments it was 

 found that : 



in 32 cases, there was a bilateral sinking of the broad liga- 

 ments accompanied by bilateral ovarian cysts ; 



in 24 cases, the sinking was bilateral and the formation of cysts 

 unilateral, in the right ovary ; 



in 10 cases, the sinking was bilateral and ovarian cysts occurred 

 only in the left ovary ; 



in 4 cases the sinking and ovarian cysts were alike found on 

 the right side only ; 



in 3 cases the sinking and cysts were found on the left side 

 only ; 



in I case the sinking was bilateral, the right ovary cystic, the 

 left had undergone fibroid degeneration ;
