INTERNAL HEMORRHOID!?. 
if 1 may be allowed the expression (even should the injury 
be extensive and the circumstances trying), to repair the 
breach. The accident will speedily be followed by a healthy 
inflammation; callus, should it be the solution of continuity 
in a bone, will form, and throughout the vis medicatrix 
naturae will exert (apparently unopposed) its salutary influence, 
and proceed secretly, silently, but no less surely, to accomplish 
the desired end. In another, no such appetency or disposition 
will obtain, no healthy local phlegmon will succeed, but sym- 
pathetic fever, accompanied with excessive nervous irritability, 
will supervene, and death more or less rapidly close the scene. 
INTERNAL HEMORRHOIDS AFFECTING A 
PONY. 
By the Same. 
On the SOth of March last, a small white pony, the pro- 
perty of Major Strange, Commanding 2d Light Cavalry, 
w ? as admitted into the infirmary with fever. He was recovering 
from the effects of the attack, although there was some torpor 
of the bowels and liver, with a capricious appetite, when, on 
the night of the 12th April, he ate all his bedding. When 
I saw him on the following morning as usual, he was going

Under these circumstances, I immediately attended. 
Symptoms . — The pony was standing with his back roached, 
grunting and straining violently, and making every possible 
effort to relieve his bowels. This was attended with con- 
siderable flatus, but with no evacuation of faeces. From the 
stained and bespattered appearance of his thighs and legs, it 
was evident that there had been a copious hemorrhage, and 
a large coagulum was impending from the anus. Upon a 
careful manual examination, several tumours, each about the 
size of a common hazel nut, were found around the rectum, 
about two inches from the anal opening. 
They were situated principally on the left side. The 
mucous lining membrane, covering the piles, imparted extreme 
heat to the fingers, and felt hypertrophied, corrugated, and 
knotted ; and when the hand was withdrawn, it was, by reason 
of the excessive straining which succeeded, easily discerned. 
It had a frilled appearance, and the tumours were highly
