siderable bloody pus in uterine cavity. No communication can be found 
between the bladder and the vaginal Avall or between the vaginal wall 
and the rectum. The intestines are negative. Mesenteric glands en- 
larged and caseous. 
Abortion and miscarriage are occasionally seen in the 
monkeys, rodents and ungulates. The underlying reason 
for this can seldom be determined. A few cases seem to 
depend upon annoyance or abuse by cage-mates, a few to 
immaturity of the mother and some others seem the 
result of bone diseases such as osteomalacia. It does not 
occur regularly in any group or enclosure and appears to 
have no comparative pathological value. 
Injuries of the external genitalia of the nature of 
lacerated wounds are occasionally seen in ungulates and 
carnivores, but never in monkeys. Acute vaginitis, some- 
times localized into an abscess of the wall has been known 
to follow these traumata. Chronic changes have been 
met but once, which example will be detailed under 
another heading. 
Inflammations. 
Endometritis has been observed sixteen times, as fol- 
lows : Carnivora 10, Rodentia 3, Ungulata 2, Edentata 1. 
In searching for causes it was found that the association 
with a recent delivery of young, an abortion or the reten- 
tion of a fetus, was responsible five times. Association 
with tumors of the uterus was noted four times. Injury 
preceded the condition on two occasions, while one 
instance seemed to be hematogenic, being secondary' to a 
septic pneumonia. On four occasions the actual cause 
could not be established with satisfaction. Pathologically 
the traumatic and parturient cases were purulent while 
tumors seemed to produce a more exfoliative or hyper- 
trophic inflammation. 
Inflammation of the Fallopian tube has been observed 
but five times, and only in one of these did the uterine 
wall fail to participate in the disease. The animals
