I opened bowels from rectum forward, and at greater curve 
of sigmoid flexure of colon I found what I was looking for, 
i.e., the cause of bleeding. 
I found an adherent clot about the size and shape of half 
a hen’s egg. Removed it carefully, and upon washing the 
bowels found a loose flap of mucous membrane, correspond¬ 
ing in size to above clot and adherent by about an inch of its 
edge to the bowels. 
There was no trace of an old ulcer, or any enlargement 
of blood vessels; on outside of bowels the surface was nor¬ 
mal. Plenty of faeces posterior to injury and nothing in them 
that would produce mechanically an injury of this kind. 
This flap of mucous membrane, under strong magnifying- 
glass appeared normal, and had very ragged edges. 
Moral: Have box-stalls smooth all around, corners rounded 
and lining sloping in.

RUPTURE OF THE INTESTINES PRODUCED BY AN 
CEGAGROPILE. 
By MM. Neyraud and Leblanc. 
This cause has been seldom reported—hence its interest. 
An aged mare is refusing her morning meal and is sent to 
the infirmary where she is placed on observation. Towards 
the afternoon she manifests some colics and was given a sim¬ 
ple treatment, which gave but little relief. The next day 
she is considerably worse. She stands quiet, in a comatose 
condition, with her legs stretched apart, has marked tympan-j 
ids of both flanks, more on the left; the respiration is acceler¬ 
ated and snorty, the nostrils dilated, the mucous membranes 
pale; the pulse is not counted as the artery cannot be felt 
under the skin. The mare has no passages. 
In the presence of this series of symptoms a positive diag¬ 
nosis could not be made, except that of an internal hemor¬ 
rhage. The mare died in a short time and at the post-mortem
