The cat from which the accompanying specimen was obtained 
was brought to the Pathological Laboratory of the Johns Hop¬ 
kins University and the following history was given by the owner. 
The animal’s abdomen commenced to enlarge six years ago; 
the swelling gradually increased since then. She had no kittens 
during this period. Locomotion was difficult on account of the 
large abdomen. Her general health was said to be good and her 
appetite normal. One week before her death the umbilical girth 
was 70 cm. There was very little sagging in the flanks and on 
percussion a distinct wave of fluctuation could be elicited. The 
death was gradual, the animal in the last few days refusing to 
eat. 
Autopsy by Prof. Welch .—On opening the abdomen it was 
found to be perfectly dry. The vagina just within the orifice was 
greatly constricted, not admitting the finest probe. Above this 
it was slightly dilated. Both uterine cornua were enormously 
dilated throughout their entire length resembling sausages in 
their contour. The length of each was 45 cm. and the maxi¬ 
mum diameter 25 cm. Each presented three constrictions with 
corresponding bulgings. Both passed outward, upward and then 
downward and inward. 
They were smooth and glistening and of a pinkish color. On 
their anterior and posterior surfaces, however, near their origin 
were large areas covered by whitish nodules varying in size 
from a pin’s head to 2 mm. in diameter. These were not sur¬ 
rounded by any inflammatory zone. Similar nodules were pres¬ 
ent along the lines of constriction. Numerous branching blood 
vessels were seen coursing over the walls of the cornua. Shining 
through the walls, especially over the middle portions of the 
cornua, were many small irregular dark red patches, resembling 
ecchymoses. The cornua together contained 2600 cc. of a thin, 
dirty, greyish white pus. This had no odor, contained many 
large cells filled with fat droplets, polynuclear leucocytes, de¬ 
tritus and myriads of short bacilli with rounded ends. These ba¬ 
cilli were half as long again as broad and closely resembled the 
colon bacillus in form. Cultures from the pus were negative.
