M. L. TRASBOT. 
or five weeks the bronchitis of gourme is cured, the nerve may 
be sufficiently atrophied under the influence of the compression 
made by the enlarged ganglions to have lost its functions ; the 
animal is a roarer. 
Is there another mechanism ? I do not know. But I am 
brought to accept this by the minute anatomo-pathological ob¬ 
servations that I have made. 
From these considerations it results that bronchitis is a com¬ 
plication of gourme, not only a serious affection per se, but also 
dangerous by the almost fatal result above mentioned. 
Many observations could I mention to demonstrate it. One 
significant will be sufficient. A handsome percheron stallion, 
perfectly healthy, was presented to the Universal Exhibition of 
1878. While there he contracted gourme, complicated with 
bronchitis, which lasted six or seven weeks, after which he was a 
confirmed roarer. Three months later he was in the same con¬ 
dition. 
For me there remains no doubt that many cases of roaring 
take place in that manner. Therefore, I advise the veterinarians 
who practice in the breeding districts or who may have oppor¬ 
tunity of gathering good observations on that subject, not to 
neglect them, and thus bring important facts likely to completely 
elucidate the question. 
As to pneumonia, it is the most serious of all the gourmy 
complications. Whether lobar or lobular, almost always it termi¬ 
nates by suppuration and gangrene, followed by death. The 
purulent collections have often, wrongly, been considered as old 
lesions. On the contrary, they are developed in very short time. 
In animals which may have died after four or five days of sick¬ 
ness they may already be very large and numerous; an impor¬ 
tant fact which must not be overlooked when one is called to 
judge as to the date of a pulmonary disease. 
It is not the presence of pus in variable quantity which char¬ 
acterizes the old existence of the affection, but only the fibroid 
induration. I have no desire to describe at present those anato¬ 
mical lesions. I may only notice the frequency of one amongst 
them in the very recent pneumonia of gourme.
