COMPTE 11ENDU OF THE 
last resource, and not to forget the precept, that the subtraction of 
any great quantity of blood is injurious, especially in climates un- 
der the influence of almost continual humidity. It sometimes places 
the patient in a state of feebleness that exposes to a relapse, and 
retards the means of convalescence. 
In the affections of the respiratory passages the revulsive treat- 
ment is not always exempt from danger. It occasionally leaves 
some serious complications, especially when the use of setons has 
been deemed necessary. When they are applied to the walls of 
the thorax or the chest, they may be followed by a voluminous en- 
gorgement, which has the character of gangrenous oedema, and 
death. 
Pneumonia, complicated with affection of the head, occasion- 
ally presents itself. 
An entire carriage horse contracted inflammation of the lungs by 
rain beating upon him. He was sent to the hospital, after having 
received some prior treatment. He was bled at the jugular. The 
movements of his flank, his cough, and the character of it, furnished 
by auscultation, confirmed the existence of acute pneumonia. The 
artery was distended and the pulse strong and frequent. The anti- 
phlogistic treatment was adopted 
On the evening of the same day, about four o’clock, a serious 
appearance was remarked ; the mucous membranes had a yellow 
tint, and the muscles were in continual action. Five minutes after- 
wards, there was great irregularity in every motion. He sud- 
denly fell — the muscles of the neck and face were contracted — 
the eyes were in constant action — the mouth was filled with 
spume — the respiration was painful — the beating of the heart 
was tumultuous, and the pulse scarcely to be felt. After some mi- 
nutes, the crisis all at once ceased ; the animal regained his tran- 
quility, and began to eat his litter. 
These nervous phenomena were regularly manifested at morn- 
ing and night : the animal trembled, beat his head against the 
walls, contracted violently the muscles of his neck, and made vain 
efforts to relieve himself. He again raised himself a little, and 
then fell, and remained couched some time after the cessation of the 
most alarming symptoms. 
We usually had recourse to the use of infusions of valerian, given 
internally. This was replaced by asafoetida, which was repeated 
in doses of ten grains. 
Under the influence of this medication, these fearful appearances 
lost their intensity, and the horse completely re-established himself. 
During the last days of summer, a case of pneumonia, very 
much resembling this, exhibited itself. The disease presented this 
remarkable difference, that in place of the symptoms of essential
