724 ABSCESSES IN THE UMBILICAL ARTERIES. 
The calf had been poorly from the Saturday preceding, and 
nothing had been done to it. Pulse and respiration were a little 
increased. He could not get up, and had nearly lost the use of his 
posterior extremities, but could stand when lifted up. Would 
not suck. 
Post-mortem appearances . — About each hock there was effu- 
sion of serum and lymph. The spleen was as large again as usual, 
and its peritoneal covering was highly inflamed. Externally, at 
the umbilicus, there was a round tumour, the size of a small egg, 
and, on cutting into which, it was found that an abscess had formed 
in each of the umbilical arteries, or, more anatomically speaking, 
in the round ligaments of the bladder. The abscesses were sur- 
rounded by a strong white substance, almost similar to cartilage. 
About an inch farther along, and closely united to the bladder, 
was another single abscess, filled with pus of a thin consistence, 
in the coats of which its ligaments could be seen terminating, but 
a little farther along they were again visible, and contained a little 
coagulated blood. 
Case II. — On the 8th October, 1844, I examined a fat calf, five 
weeks old, that was killed by a butcher. It was a good one, but 
not very fat on its loins, and the butcher was inclined to think that 
the following disease would in time have caused its death. 
Examination . — Attached to the fundus of the bladder was an 
abscess as large as one’s fist, containing white pus, and which 
abscess was also attached, by a short thin peduncle, to the umbili- 
cus. The bladder was natural, and inflated with air. The two 
round ligaments terminated near the fundus of the bladder in the 
sides of the sac of the abscess, but on the sides of the bladder they 
again made their appearance. 
DIVISION OR DOUBLE BLADDER IN A CALF. 
On the 30th May, 1844, Mr. Allen, butcher in this town, killed 
a fat calf, about five weeks old. After removing the bladder, it was 
found that the water could not be extracted from it. The spe- 
cimen was therefore sent to me for examination. 
It was of a circular shape, and had the appearance of a highly 
distended small bladder, containing about twenty ounces of fluid of 
an amber colour. The centre of its apex was slightly attached to the 
umbilicus, and the opposite end to the true bladder, which was, I 
think, smaller than usual. On laying open the neck of the true 
bladder 1 could plainly see that there was a distinct division 
between its fundus and the sac below. The coats of the true blad- 
der were four times as thick as those of the other, but were normal. 
The coats of the other were very thin, and divisible, to all ap- 
pearance, into two parts — a peritoneal and an internal one, with but
