THE DISEASES OF PIGS. 
and every organ was sound except the brain. The meninges of 
the brain were completely gorged with blood, and in some places 
there was extravasation of blood slightly penetrating into its sub- 
stance. The other part of the brain was not inflamed, nor was 
there any effusion of serum in its ventricles. 
Cause of death . — This pig was about five score weight, and 
feeding fast. He had, a few days before, a quantity of grains 
given to him, which had most probably brought on the disease 
in the brain, and had disordered his intellect. Perhaps it had 
rendered him somewhat insanely ravenous, and caused him to 
destroy the fowls. There is a saying that, “ rum while in hogs- 
heads is capable of doing but little mischief, but when it gets 
into men’s heads — look out!” but I fancy that if any consider- 
able quantity of the unfermented liquor was contained in the 
grains after brewing, it would produce an injurious effect. 
RUPTURED SPLEEN. 
Nov. 1840. — I examined a pig belonging to Mr. Roberts, that 
had died after having been ill but a day or so, and without shew- , 
ing any well-marked symptoms of disease. I found from three 
to four quarts of bloody serum in the abdomen, and the spleen 
was from three to four times its natural size, and completely con- 
gested. In one place there was a small rupture, around which 
was a quantity of coagulated blood. All other parts were sound. 
DISEASED LUNGS — PHTHISIS? 
In the months of Nov. and Dec. 1840, several small pigs, be- 
longing to butchers, died. They had been feeding on potatoes 
and carrion, and on opening them I could discover nothing else 
amiss than disease in the lungs. The anterior lobes were the 
parts generally diseased, and these were found to be, on handling 
them, hard, heavy, and uneven, and had neither the feeling nor 
appearance of the healthy portions. On cutting into them they 
appeared to be composed of miliary tubercles in an early stage 
of suppuration. The disease did not appear to be in the bronchial 
tubes, but in the cellular or parenchymatous tissue. After a por- 
tion had been cut through I thought some specks of pus could 
be seen. When alive they had symptoms of diseased lungs, and 
their respiration was greatly accelerated ,* they were also often 
coughing. 
DISEASED HEART. 
28th April , 1840. — I examined a dead pig that was half grown. 
The owner purchased it about ten days ago, but soon after it was 
brought home she found that it was not a good feeder, and that
