12 PLEURISY — RHEUMATIC INFLAMMATION, &C. 
dressing her, the butcher discovered that her stifles were much 
enlarged. On laying open these joints, I found that they contained 
a little sanious matter, and on disarticulating the tibia from the 
femur, I found that the heads of both these bones were carious to 
a great extent, especially on the inner surfaces, and that the heads 
of the bones surrounding the joints were much enlarged. I did not 
examine any other joint, as she was good meat. Her spine was 
then sawn through. Over the loins the spinal marrow was de- 
cidedly red and inflamed, and very different to any part of the 
remainder. The inflamed part had streaks of bloodvessels running 
both on the theca and in the texture of the cord. The other part 
of the cord was beautifully white. 
His Lordship, Captain Cotton, and Mr. Blantern, the bailiff, were 
present at the post-mortem. Several other similar cases have 
occurred at the Favon-yard, and I have every reason to believe it 
is not a rare disease.

TROPHY OF THE HEART— DEATH. 
By William Percivall, M.R.C.S., and V.S. 
A BLOOD MARE, four years old, of slender form, but with limbs 
and other points such as bid fair, one day, to render her powerful 
enough to carry weight, was out of health at the time she was pur- 
chased for my regiment, which was in April last ; she, however, in 
a few weeks appeared to have recovered herself, and was about to 
be taken to be broke in, when she was seized (11th Aug.) with 
the influenza, prevalent about that time. This, though slight, and 
apparently trifling at first, stealthily increased on her, and at length 
ended on the 16th — five days after — in decided pleurisy. Being 
low at the time, it was deemed inadvisable to let blood ; however, 
her symptoms had become so much aggravated — her breathing so 
irksome — that, on the 19th, there was no longer resisting blood- 
letting; and accordingly her jugular was opened, and she bore 
extremely well the abstraction of seven pints of blood. The effect 
of this was, that, on the 20th, her breathing had become tranquil, 
and the mare was decidedly better. From this time, with the aid 
of medicine and counter-irritation, she tardily progressed in return- 
ing health, was led out every day, and thought to be, though slowly, 
still surely, amending ; when,
