ON INFLAMMATION. 
ized to be immediately removed; and, in the form of callous, or 
splent, or spavin, or engorgement, or hepatization, it long re¬ 
mains, to the injury or destruction of the function of the part. 
The fain is easily explained, whatever may be our conception 
of the nature of inflammation. The vessels are distended, 
there is considerable interstitial deposit; and, consequently, the 
neighbouring parts will be compressed and suffer. Although 
the nerves which supply the muscular coat of the capillaries are 
unconnected with voluntary motion, or the sensations of plea¬ 
sure or pain, they anastamose very freely with the nerves of the 
spinal. Voluntary motion, indeed, is withheld, because the im¬ 
portant functions of life would often be ill-discharged if they 
were subjected to the caprices of the will; yet the sensations of 
pain and of pleasure are necessary to prompt us to certain actions, 
and to warn us against dangers and death ; and therefore the 
organic nerves anastamose so abundantly with the nerves of ani¬ 
mal life. Quadrupeds give indication enough that they feel the 
torture of inflammation as keenly as the human being. The ex¬ 
pressive, lingering look at the flanks in inflammation of the 
bow els or of the lungs; the incessant shifting of the feet, and 
fevered pulse, and anxious countenance, in acute founder, indi¬ 
cate that w hich cannot be misunderstood. The pain is produced 
by inflammation, but it is referrible to another set of nerves, 
connected, how ever, with the ganglial by innumerable commu¬ 
nications. . - 
These are the four principal indications of inflammation. They 
are all of them satisfactorily explained by the definition of inflam¬ 
mation that has been adopted ; w hile the redness and the heat of 
the inflamed part do not admit of explanation on any other hy¬ 
pothesis.

A CASE OF LOW FEVER, OR CHRONIC AFFECTION 
OF THE HEART. 
By W. Y. 
On the 9th inst. I first attended a pony 12 hands 3 inches 
high, belonging to a gentleman. It had not fed well or been 
in its usual spirits for several days, and previous to that had 
been ridden by children and driven about, and exposed to cold 
and wet more than had been customary. The pulse was 48, a 
little languid, and decidedly irregular; the mouth somewhat 
hot; the ears and extremities more than usually warm; the 
breathing very slightly laborious; the membrane of the nose 
slightly but darkly injected with streaks, or rather ramifications
