pearance sound. But on his first going out he again became 
lame, and the gentleman determined to have him unnerved. It 
was performed early in the spring, and about one inch of the 
nerve excised. He got up, and went free from lameness. He 
was hunted all that season and some portion of this, until by an 
accident he fractured one of the lumbar vertebrae, and was obliged 
to be destroyed on the spot. After death I had the pleasure of 
examining his foot, which put on the following appearances : — 
The anterior: ligament, uniting the navicular with the coffin 
bone, was partly ossified, as was also that one which joined it to 
the flexor tendon. The navicular bone itself was carious in two 
parts, and the peridesmium and pericondrium were united, and 
the joint almost destitute of synovia. Such were the appear¬ 
ances on dissection : before the operation, the horse was so lame 
as to be entirely useless; but after that operation, he was as 
good a horse as any in the field. Such is the state of the case, 
and very plainly sets forth the utility of an operation which will 
hand down to posterity the name of the gentleman (Mr. Sewell) 
who revived, if not discovered, this very valuable mode of allevi¬ 
ating suffering.

SPEEDILY FOLLOWED BY DEATH.

By W. Percivall, Esq. 
This horse (who was in his fourth year) was found, at seven 
o’clock in the morning, in the following condition:—He was 
sweating profusely; heaving hard and quick at the flanks; puff¬ 
ing at an equal ratio at the nostrils; the pulse could be but very 
indistinctly felt either at the jaw or heart, and it did not seem to 
keep pace with the respiration; the mouth was hot and clammy; 
the^ legs intensely cold, although other parts were wet with 
sweat; the head hung down, and the countenance betraying 
serious malady; the eyes reddened, the nose likewise, and moist 
with yellowish sanious matter, accompanied with foetid breath, 
which offensive odour also proceeded from the mouth. When 
pressed upon the side he flinched and turned his head round, 
evincing much soreness in the part. 
As soon as he could be got dry and clothed up (for his skin 
had begun to grow cold from being wet with sweat) he was bled. 
But two quarts of dark-coloured thick blood had flowed, how¬ 
ever (and that in a slow stream, and obtained with much diffi¬ 
culty), before he began to stagger, rendering it necessary to stop
