The symptom which lasted longest was the sonorous respira¬ 
tion. Early bleeding from the jugular, poultices of linseed meal 
moistened with a decoction of poppy-heads applied to the throat, 
blisters and setons at a distance from the seat of the disease in 
order to produce a revulsive irritation, were generally of little 
service during the first ten or twelve days. Recourse was after¬ 
wards had to setons on the front of the chest, and, lastly, to blis¬ 
ters on the throat. 
In one of these animals, towards the thirteenth day of the dis¬ 
ease, a considerable quantity of white purulent matter, rather 
thick and a little foetid, ran from the nostril. From this moment 
the guttural sound became weaker; the next day it could only be 
heard when the patient was eating his hay. It was hardly per¬ 
ceptible even then two days afterwards, when the horse was 
taken from our infirmary. Nevertheless, however weak this re¬ 
spiratory noise had become, it remained until the 8th of August, 
and then only really yielded to the influence of a purgative dose 
Of aloes. 
This laryngo-bronchitis appeared in a horse labouring under 
farcy; the same treatment then completely failed: recourse was 
afterwards had, seeing the inutility of all other means, to the 
operation of tracheotomy, in order to keep the larynx com¬ 
pletely quiet : the noise immediately ceased almost entirely, and 
this good effect continued for five or six days; but it returned as 
bad as ever, when the tube got displaced. Lastly, about a 
month or six weeks after the commencement of the disease, when 
the owner wished the tube to be entirely removed, the respiratory 
noise returned as loud as ever. 
This horse, although his appetite was good, got thinner every 
day, and at length was destroyed, in the hope that we might be 
able to discover some of the causes of these symptoms. Ulcers 
resembling those of farcy were found in the mucous membrane of 
the trachea, near the bronchise. Similar ones existed round the 
place where the tracheal artery had been punctured, but the 
ulceration had made the greatest progress on the larynx: the 
glottis was one vast ulcer, which extended to the base of the 
epiglottis; the mucous membrane was thickened and carcino-
