the hocks and knees. Upon laying open the abdomen, and cut¬ 
ting through a large accumulation of fat in the mesentery— 
it being; two or three inches in thickness—from two to three 
gallons of darkish-coloured fluid made its escape. All the 
organs were healthy, except the following: the liver was 
natural in size, but of a very pale clay colour, and upon being 
removed, was found to be very much diseased; every portion 
of it, except a small part of the left lobe, was so completely 
softened, as that within its capsule it could be spread 
with a knife: no rupture had taken place. The spleen 
was also of its natural size, but of a deep-black colour; and 
within its capsule its structure much resembled thick black 
ink. Upon the abdominal surface of the diaphragm, where 
it lies in contact with the right lobe of the liver, were found 
a great number of small, white, hard, nodular enlargements, 
varying in size from a pin’s head to an ordinary pea. The 
contents of the thorax were healthy, with the exception of 
the lungs, which were much congested. 
TRISMUS IN A COLT. 
By John Darcey Peech, M.R.C.Y.S., Wentworth. 
The following case of trismus in a colt, being one of 
rather unusual occurrence, may render it worthy of a passing 
remark. 
In the month of July last my attention was called to a 
thorough-bred Barnton colt, in a large breeding establish¬ 
ment several miles from this place, reported to be very 
unwell. 
On my quietly entering his box, little could be perceived 
to be the matter with him at the first glance, and a casual 
observer would not have discovered anything amiss, beyond 
his looking a little light in the body. 
Inquiring into the history of the case, I found that he, 
with several others, was “ put on physic” on the previous 
Tuesday, and the whole of them were moderately purged, 
with the exception of this one, whose medicine operated more 
briskly than that of the others. On the Thursday morning, 
three of the colts were found to have slight oedema of the 
throat, unaccompanied with soreness, the tumefaction being 
confined to the maxillary space and laryngeal region. With 
friction and mild vesicants, this quickly subsided ; indeed, 
so much so, that by Saturday the swelling had disappeared
