738 PIGS POISONED BY EATING DECAYED VEGETABLES. 
that another pig was past recovery; and considering that I 
had taken an interest in the former cases, the owner thought 
I should perhaps like to make a post-mortem examination of 
this one. I attended at once, and found the animal dead, 
lying on its abdomen, with both the fore and hind legs 
outstretched. The belly also was greatly distended. Being 
much engaged at the time, I could not stay to make an 
autopsy, and therefore deferred it until the next morning. 
After making a longitudinal incision into the abdominal 
cavity, and a small opening into the caecum, I drew back to 
avoid the effluvia I expected to escape, but 1 was soon un¬ 
deceived; for instead of gas, I had given vent to full three 
pints of straw-coloured and transparent urine, which had 
flowed through a rupture of the coats of the bladder. The 
urine gave, on examination, a marked acid reaction; but it 
possessed no other peculiarity that I could discover. The mus¬ 
cular structure of the bladder was thrice its natural thickness, 
and the mucous coat was reddened, and appeared to be one 
mass of minute ulcers. The rupture was of a circular shape, 
with ragged edges, about the size of a sixpence, and situated 
at the extremity of the bladder furthest from its attachment. 
The ureters and the prostatic portion of the urethra were 
larger in calibre than natural, and, as well as the medullary 
portion of the kidneys, were somewhat reddened. The lungs 
and spleen were hepatized, and interspersed with scarlet 
patches of congestion. I was particular in searching for any 
traces of the late poisoning. The rusty-yellow colour of the 
pyloric oriflce of the stomach, so peculiar in the other 
animals, was faintly visible. The villous coat was thickened, 
but not to the extent seen in the former cases. The mucous 
coat, throughout the entire length of the digestive tube, was 
extremely thin, and appeared in several places to have dis¬ 
united itself from the muscular. 
The other pig is well, and in fine condition.
