CONTRIBUTIONS TO THE PATHOLOGY AND 
twelve months ago the animal became affected with cough, which 
was not violent ; and, at times, the owner states that the horse 
would be for a day or two without coughing, then he would cough 
for several times in succession. The cough itself was hard and 
dry sounding, and it did not appear to be excited from any par- 
ticular cause. Three months ago it became more frequent and vio- 
lent, but the owner neglected to apply for any relief, from the sup- 
position that the cough arose, in a great measure, from old age, 
and that the animal was about to lose his wind. 
Two hours ago the horse in question was turned out of the stable 
along with two others to drink what water he chose out of a trough 
in the yard, and soon after drinking the animal began to breathe 
with great violence, and stagger in his walk. Several remedies of 
a simple nature were had recourse to, but without avail : the case 
got worse; when, at last, the owner sent off a messenger to request 
my immediate attendance. 
Present State. 
1. Pulse 74 per minute, full and strong; the impulse of the 
heart is also very powerful against the ribs of the left side. 
2. The respirations are 40 per minute; the ribs heave violently, 
and the inspiratory act is attended with a suppressed screaming 
noise. 
3. On applying my ear along the course of the trachea, a loud 
rasping noise is present : this noise is of the same intensity in 
every part of the tube ; at least, the most careful examination I 
could make failed to detect any difference. 
4. The respiratory murmur throughout the chest on both sides is 
subdued, or of a muffled character. 
5. The animal stands stiffly in the stall ; the limbs are placed 
wide apart; the nose is extended, and the nostrils are widely 
expanded. 
6. The surface of the body, generally, is covered with a cold 
clammy perspiration. 
7. Occasionally the animal brings his nose close to his left side, 
and regards the side anxiously. 
8. The eyes are staring, blood-shot, and have a peculiar wild 
look.

In about an hour after the medicine was given, the most violent 
of the symptoms had subsided considerably. In the mean time the 
animal was wisped dry, and warmly clothed. At ten o’clock I
