Present Symptoms. —The head of the mare is drooping ; the 
eyes dull; three of the extremities are preternaturally warm, the 
other is cold ; the hair over the surface of the body has a very dull 
unhealthy appearance. When I press my hand against the sides of 
the chest, a soreness is manifest, and a slight tremor of the panni- 
culus carnosus muscle is evinced: this soreness is a little more 
acute on the right than on the left side; the mucous membrane of 
the nose is of a dull red, and shadowy ,* the pulse is feeble, and 
beats at 70 per minute ; respiration 15 ditto. On applying my 
ear along the course of the trachea, commencing superiorly, I hear 
a soft mucous rale, which slightly increases in loudness as I 
approach with my ear to the breast: close to where the trachea 
enters the chest the rale is most intense; the loudest to , how¬ 
ever, is very low, compared with the same kind of soun I have 
heard under similar circumstances. The respiratory murmur I 
hear over the whole of the left side of the chest; its highest tone 
on this side is parallel to and about four inches wide of the 
spinal column; in the regions more inferior it becomes more sub¬ 
dued : on the right side, along its superior part, the sound is very 
similar, but along the median region it is decidedly more sub¬ 
dued, and in the inferior region it has entirely ceased. 
In this case 1 need not take the reader through the daily pro¬ 
gress of the disease; its course was so closely similar in every 
respect to the first, that to do so would be little else than to give a 
mere repetition of what I have already stated; suffice it to say, 
that the animal died during the afternoon of the 11th: that, for 
three days prior to death, yeasty-looking matter was discharged 
from the nostrils, of a most intolerable stench ; and that, about the 
time this discharge commenced, the skin in one or two parts, 
particularly about the right shoulder, appeared a little inflated ; 
and this, when pressed upon, caused a cracking sound, which I 
have no doubt arose from gas or air being collected in the cellular 
tissue of the part, which, when pressed upon, ruptured the cells 
of the tissue, and thus caused the crepitation alluded to. 
Examination seventeen hours after death. Abdominal Viscera : 
The stomach was empty, also the small intestines—the large in¬ 
testines contained brown matter in a semi-fluid state. The colour 
of the mucous membrane was a pale dull red, with here and there 
a darker tinge intermixed with blue; the colour of the peritoneum 
was normal. The liver was very sound, but pale The intestines, 
from the commencement to the end, were softened, and very little 
exertion sufficed to tear their tissues asunder. 
Organs of the Chest. —The substance of the lungs and the 
bronchial tubes were in a state of disorganization—their structures 
were torn apart with very little force: numerous abscesses were
