ANIMAL FOOD IN VETERINARY PRACTICE. 
transparent serous fluid. Its walls were considerably thick¬ 
ened^ and could.easily be detached from the structure of the 
diaphragm. Before the cyst was laid open it measured as 
much as six inches in diameter. The precise situation of 
the cyst was at the inner border of the outer muscular por¬ 
tion of the diaphragm, and about midway between the ensi- 
form cartilage and the spine. The muscular tissue at this 
part of the diaphragm had entirely disappeared. There was 
no indication, as far as I could detect, of adhesion as a 
result of inflammatory action either between the organ 
and the lung in front, or the coverings of the liver behind ; 
and as both these organs were free from disease, it is 
difficult to determine what could have given rise to the for¬ 
mation of the cyst. The only conclusion I could come to 
respecting it was that it partook of the nature of an hydatid, 
which idea is strengthened by the fact that the wall of the 
cyst itself had no connection by continuity of structure or 
blood-vessels with the structure of the diaphragm. 
ON THE EXHIBITION OF ANIMAL FOOD TO 
HERBIVOROUS ANIMALS IN VETERINARY 
PRACTICE. 
By Professor Varnell. 
A FEW months ago I was requested to see a horse, the 
property of a gentleman living at Highbury, which at the 
time was under the care of a veterinary surgeon. It is not 
my intention to describe the particulars of the case, as they 
have no important bearing on the circumstances which I have 
lately been put in possession of relative to the horse^s 
recovery. I may, however, remark, that at the time I saw 
the horse he was suffering severely from what I considered 
to be intestinal obstruction, and I was told that the attack 
had then lasted three days with slight intermissions. I must 
confess that I was unable to diagnose the case to mv satis- 
faction, but my prognosis, however, was very unfavorable. I 
suggested a change in the treatment, which I believe was 
carried out to the letter. I heard no more of the case until I 
received the following communication from the owner of the 
horse, informing me that the animal had recovered. 1 have 
no doubt, however, that for a time he was very weak and ill.
