surrounding tissues, with which it is continuous. In case of an 

 open cervical canal, the lips of the os uteri are enlarged, smootli, 

 velvet-like, infiltrated. In many instances, especially when 

 there exists a prolapsus portionis vaginalis uteri due to recurrent 

 cystic disease of the ovaries, there are one or two flaps which are 

 readily recognized in the vagina as bodies as thick as the hand, 

 broad and long, tongue-shaped and often infiltrated with blood, 

 upon the surface of which one may recognize, by palpation, the 

 OS uteri. 



Now and then there exists, as a result of chronic irritation in 

 connection with the pathologic dilation of the cervical canal and 

 the swelling of the vaginal portion of the uterus, in cows suffer- 

 ing from cystic or fibrous ovarian degeneration, an enlargement 

 and conspicuous firmness of the cervix tderi, sometimes slight, 

 sometimes the thickness of the forearm or arm, and without any 

 increase whatever in the size of the cornua. 



Passing to the changes in the uteri of nymphomaniac cows 

 and heifers, recognizable by palpation, it is to be pointed out 

 that the size of the organ in quite recent and not severe cases 

 must now and then be regarded as normal. So, for example, 

 we observed in one mild and very recent case of nymphomania 

 in a cow which had aborted at the end of the fourth month of 

 pregnancy, eight weeks after the abortion, a bilateral sinking of 

 the broad pelvic ligaments, a large ovarian cyst in the right 

 ovary, normal volume of the uterus and closed uterine os. 



However, in the great majority of nymphomaniac cows, the 

 patients show a very variable degree of increased volume of the 

 uterus, either in toto or chiefly only in one horn. Often the uterine 

 body at the point of origin of the cornua is only .slightly thick- 

 ened, the size of a child's arm ; in other cases, as thick as a 

 man's arm. 



Simultaneous with the increased circumference, there occurs 

 also a varying elongation of the uterus to the extent of 2 to 3 

 times its normal length, whereby its anterior end projects far 

 into the abdominal cavity. 



In asymmetric uteri the right horn is greater in 75% of cases 

 and only exceptionally is one horn found to be normal while the 

 other is importantly increased in circumference and length. The 

 consistence of the uterus, which is never abnormally sensitive,
