ON PERIPNEUMONIA IN CATTLE. 579 
malady and convalescence ; and he added, that many of his 
cattle, cows as well as ewes, had shewn lameness (from rheu- 
matism!) while they were ill. 
M. Maret, veterinary surgeon at Allanches, has frequently 
observed swellings in the joints of the knee and hock in sick 
calves; and, moreover, he has shewn, there has been some altera- 
tion in the synovia. 
I have remarked upon Faucen’s farm, which was on the ad- 
joining mountains, the same enlargement of the bursae of the 
tendons in a calf ; and a little farther than his farm, in the cow- 
establishment at Pradt, four cows, which had had the epizootic, 
have still shewed enlargements, some in the knee, some in the 
hough. 
And M. Cobeal, whose spirit of observation is well appre- 
ciated, and who has had his cow-house all but desolated by the 
epizootic, has declared to me that the recovered beasts continued 
for some time afterwards affected with lameness and pains in 
the hip and hough, and even soft tumours in various parts of the 
body. 
So that the disease of the synovial capsules and the serous 
collections which appear in different parts constitute a subject 
to which our attention for the future must be directed. 
As to the fetid character of the expired air, we must, as was 
before observed, make a distinction between that expired through 
the nostrils and that which passes through the mouth. The 
denomination, formerly given erroneously, to this peripneumonia 
of gangrenous, led to a belief that the air expired from the 
lungs must necessarily be tainted with a bad odour. 
In all the diseased beasts I have subjected to examination, l 
have on no occasion perceived offensive odour from the nasal 
cavities, though the same result has not been apparent when the 
mouth was opened, and the nasal cavities were plugged up. I 
scented the odour of the air as it issued through the mouth. 
The air was then offensive ; but this admits of ready explana- 
tion. As soon as the animal gives over eating and ruminating, 
the saliva and mucus lodging in the buccal cavity will undergo 
a change; there can be no reason for surprise, therefor^, should 
the air in passing through this cavity become charged with 
fetor. And where several sick beasts are lodged in the same 
stable, some of them will naturally cast saliva upon the manger, 
while others may have setons or blisters upon them; in which 
way we may readily explain how it happens that the atmo- 
sphere of the stable becomes contaminated without presuming 
that the lungs are in any way gangrenous. 
And besides, the acuteness and rapidity of the disease are not 
at all equal to what usually happens in gangrenous affections ;
