through an examination per rectum; and the initial symp- 
toms, as the sinking of the pelvic ligaments, and edematous 
swelling of the vulva, were seldom lacking. 
The results might doubtfully be claimed for the treat- 
ment, as the early rupture of the cysts may prove, under 
certain conditions, to be a better treatment than the treat- 
ment of the metritis in a late stage. 
This consideration induced me to segregate all the ani- 
mals, which had the typical symptoms of nymphomania 
with the intention of finding out if the treatment of the 
metritis alone could influence the nymphomania. 
In the year 1906 I treated thus 107 cows with nympho- 
mania; some of them were fresh cases, but others were quite 
old, a few even of a year’s duration. These cows were ob- 
served for a long time, so that an eventual relapse would 
have been noted. Pregnancy was in all cases determined 
by rectal examination. 
Of these 107 cows 92, or 86%, were completely cured; 
two animals were castrated, eleven became partly quiet, and 
two could not be reported. Of 92 animals 72 became preg- 
nant. 
The success of the uterus treatment in nymphomania is 
therefore evident. In the majority of the cases the symp- 
toms disappeared very quickly, and in the others the relapses 
were only mild; in only a few cases could the animals not be 
kept on the pasture. 
In more than half of the animals the treatment had to be 
repeated however; 
36 cases were once 
32 cases were twice 
19 cases were three times 
7 cases were four times 
5 cases were five times 
and 8 cases were still oftener treated. 
I must say, however, that many of these animals were 
not so thoroughly treated as my present theory demands.
