CONTRIBUTIONS TO THE PATHOLOGY AND 
heard for a considerable distance; it resembles the sound occa¬ 
sioned by the sawing of wood, can only be detected during the 
act of inspiration, and it appears to be limited entirely to the 
larynx : the chest heaves violently; partial sweats exist over the 
shoulders and around the flanks. I immediately procured a ball- 
iron, and carefully examined the larynx and the other organs in 
immediate connexion with it, but failed to detect the lodgment of 
any foreign substance. 
I tried a variety of simple remedies to afford the horse relief, 
without effecting the least good. In about an hour after I was 
called in, the breathing had become so difficult that I was com¬ 
pelled to resort to tracheotomy, which had the effect of giving im¬ 
mediate relief, so much so, that in a short time he became per¬ 
fectly cool; the rasping sound entirely subsided, and the horse lay 
down apparently quite comfortable. During the evening the 
animal was several times tried with chilled water and mash, which 
he refused on every occasion. 
4 th .—The saliva still continues to run from the mouth as abun¬ 
dantly as ever. This morning he swallowed about two quarts of 
thin gruel, but appeared to suffer pain in so doing. Apply a 
blister to the throat, and clean the tracheotomy tube. During the 
day no particular alteration occurred. 
5th .—Can swallow better; has eaten a small portion of mash 
apparently without any difficulty. Pulse 40 and respiration 11 per 
minute; breathes in part through the tube, and in part through the 
nostrils. Saliva still dribbles from the mouth. Blister around the 
throat has acted well, and in every respect is progressing favourably. 
Eight o'clock, P.M. —During this evening he has begun to shew 
lameness in the near hind leg; the lameness, however, is not 
severe. I had the shoe removed, and examined the foot, but 
failed to detect any lesion there. The limb to be well fomented 
with hot water from the patella joint to the foot. Gave the follow¬ 
ing in a drench :—

6th .—Swallows gruel very freely. Can eat bran mash and hay. 
Pulse 45, regular and full; respiratory murmur throughout the 
chest on both sides normal. Has dunged once, which is of regular 
consistence. Repeat fomentation to the limb. Gave in a drench
