Death was generally prognosticated after the animal had been 
with us a few days. 
The patient, when put into the stable, receded as far as he could 
from the manger, and refused all food and drink. 
During the night he remained lying down for a long time with- 
out any moaning or apparent uneasiness, but had considerable 
discharge of blood from the nostrils. 
On the following day he died. 
At the post-mortem examination there was very little alteration 
observable in the thoracic organs. 
The opening of the abdominal cavity allowed several remark- 
able deviations from healthy structure to be observed. The ex- 
terior surface of the small intestine reflected a reddish colour 
through a great part of its extent. An incision being made into 
the interior, a considerable quantity of chylous matter escaped. 
The internal membrane of this intestine was observed to be 
full of ulcerations almost innumerable. They were of different 
sizes when examined by the microscope. The greater part were 
nearly three millimetres in diameter, the largest five, and the 
smallest one. The latter, like the large ones, had a smooth edge 
slightly protruding, and might be cut perpendicularly as with a 
pair of scissors. The smaller and the middle sized were some- 
what projecting, or presented in their centre a slight elevation, 
which was, in fact, a small portion of mucus that had not yet 
undergone the process of ulceration. 
They occupied only a superficial part of the mucous mem- 
brane, and merely seemed to be a small portion of the mucous 
membrane not yet ulcerated, and being in fact nothing more 
than a simple erosion beneath the epidermis. 
The middle-sized ones almost entirely occupied the thickness 
of the mucous membrane ; their base was smooth, and without 
any unnatural projections. 
The largest occupied the whole thickness of the mucous mem- 
brane, and their base corresponded with the sub-mucous cellular 
tissue. 
There was no vascular abnormal injection around these dis- 
eased cavities. Their border was not surrounded by any red 
areola, and the mucus was not thicker at this place than at any 
other. 
It was impossible to state positively whether they had 
their seat in the interior of the mucous follicles. We could see 
two or three of these follicles well preserved, where the mucous 
membrane was only a half of its thickness. 
Nevertheless, their form, their situation, their rounded and
