which include but a very small percentage of the total number 

 of cases of nymphomania recorded by us, it appears that, in 12 

 cases out of 120 observed during the first six months of 1905, a 

 complete return to the normal elevation of the hips or recovery 

 in tone of the broad ligaments did not occur within the normal 

 period after calving but that the sciatic ligaments retained their 

 relaxed condition during the first 12 days or increased somewhat 

 after 3-7 days. In 100 cases the normal tension of the broad 

 ligaments was reestablished within 12 days after calving which, 

 however, after the following periods of time, again became re- 

 laxed, namely :

According to these exhibits, the relaxation of the broad liga- 

 ments of the pelvis occurred during the period of most intense 

 lactation, the first 4 months after calving furnishing 77 cases, as 

 against 35 cases at a later date, or about 2:1. 



In regard to the relation between the sinking of the broad lig- 

 aments and nymphomania, the 120 cases cited above furnish the 

 following clinical data : 



The 120 cases of nymphomania showed in 112 cases a sinking 

 of the broad ligaments, and in 8 cases no sinking. 



Of the 112 cases, the sinking of the sciatic ligaments was as- 

 sociated : 



8 times with regularly recurring estrum every three months, 

 which was very intense and was prolonged for 3-4 days ; '
