vulvse, the mucous membrane being external, the cotyledons 
being exposed, also the cervix (marking the uterus from the 
vagina) being external forms a ring around the base of the tumor. 
At the bottom part, close to the vulvae, we find the opening of the 
urethra. We often have all or part of the foetal envelopes at¬ 
tached to the cotyledons. Many cases we have rupture of the 
mucous membrane with haemorrhage. There may be gangrenous 
patches—rupture of the uterus may occur with the passage of 
the intestines through the rent. 
Symptoms .—The symptoms are of value to us to guard us 
against its occurrance. After labor (the delivery of the calf) 
theanimal soon begins to strain, and to do so nearly continuously 
the back remaining arched; soon a tumor appears between the 
lips of the vulvae, this being some part of the uterus ; with a few 
more efforts the uterus is passed out entirely. After it is out the 
animal mostly is quiet for a short time, often stands eating as if 
there was nothing amiss, then there are cases where the animal 
strains for more than a day before the uterus is everted or per¬ 
haps the vagina is everted a longer or shorter period before the 
uterus. In other cases at the time of the eversion, we have the 
animal lie down and be unable to rise, either due to paralysis or 
haemorrhage ; if due to haemorrhage we have tremors, animal 
panting, yawning, and struggling, also a pale mucous membrane 
and a weak pulse. 
Complications .—We may have the paralysis due to injury to 
nerves ; perhaps she is unable to rise due to the great pain, or 
from excessive exhaustion or from haemorrhage; later we may 
have septic infection, peritonitis or gangrene of the uterus in part 
or whole. We even have a rupture of the walls of the uterus 
with the passage of the intestines through the opening. 
Termination .—With no treatment death must take place, as 
the uterus will not be replaced spontaneously, and it would be 
very rare indeed to find a case where the uterus sloughed off 
and the animal recovered. 
The diagnosis is very readily made by the large tumor ex¬ 
ternal to the vulvae, with the cotyledons exposed, and the
