appeared in the right stifle, but with much less pain. The gen¬ 
tleman took his dog away from our hospital, although still lame. 
The rhuematism gradually disappeared, the appetite remained 
good, the strength returned, the bark regained its former tone, 
but the dog did not gain flesh. On the 11th of June he was 
brought to us again, manifesting some of the symptoms of the 
disease called dumb-madness; and he died on the fourth day. 
We had thus an opportunity of examining the state of the tho¬ 
racic viscera. On that side of the thorax which had been punc¬ 
tured, the pulmonary pleura adhered to the intercostal by a 
production of ligamentous consistence, white, thin at the edge, 
having two points of adhesion two inches or two inches and a 
half wide. At the point at which this ligamentous production 
was attached to the lungs, a greyish induration was observable 
through an extension of some inches. The lungs on the other 
side were of their natural colour, and crepitating ; but their in¬ 
tercostal face presented four tuberculous kernel-shaped masses, 
which were lighter coloured, and of the same consistence as the 
rest of the ^ lmonary substance. These masses, when cut open, 
exhibited r species of cyst, the homogenous walls of which were 
about two lines thick; they were deep, and each contained a 
small quantity of white viscid pus, and communicated with the 
corresponding bronchial tube. These lesions approached more 
to the character of cysts than of tubercles. The mucous mem¬ 
brane of the digestive tube was covered with a greyish mucus, 
and betrayed evident traces of acute inflammation. The other 
intestines were healthy. 
3d. Old horses, like old men, are subject to intestinal disease. 
Many died from acute cholic and tympanitis of the belly. Punc¬ 
turing the coecum, which has been tried in such cases w'ith the 
intention of favouring the escape of the gas that distends the 
intestinal tube, and causes the pains inseparable from this affec¬ 
tion, is rarely successful. In the most favourable cases that prac¬ 
titioners have observed, purulent collections were formed between 
the muscular folds of the walls of the belly ; but their evacuation 
by a counter opening was very difficult to establish. This pus in¬ 
fuses itself between the muscular folds, extends further and fur-
