a longitudinal rupture was found towards the union of the 
colon and the rectum; it measured io centimeters (about 5 
inches) in length, with ragged edges, soft, hemorrhagic and 
with clots adherent to the borders. Between the edges of the 
laceration there was a cylindroid, large cegagropile, partly 
in and partly out of the intestines, and weighing about 300 
grammes. Besides this special lesion the abdominal cavity 
and its contents showed more or less intense inflammation 
with some gangrenous spots in the course of the intestine.—

ANEURISM OF ONE OF THE BRANCHES OF THE LEFT FAS¬ 
CICULUS OF THE GREAT MESENTERIC ARTERY OPEN IN 
THE FLOATING COLON OF A HORSE SUFFERING WITH 
PARIETAL ENDOCARDITIS OF THE LEFT HEART.

By MM. Duchene and Cadeac. 
The difficulty of diagnosis of cardio-vascular affections is 
well known, and their complications are often unsuspected. 
An anglo-normand, 18 years of age, is laid up with colics. 
On examination a champignon is found in the inguinal region, 
for which the horse is operated and rapidly recovers. Later 
on he is again suffering with dull, intermittent colics, the mu¬ 
cous membranes are pale, the movements of the heart strong 
and accelerated, micturation is difficult, the urine is dark yel- 
low, viscous and very alkaline. The fasces are at times mixed 
with blood. The animal began to lose flesh. Auscultation 
and percussion of the heart failed to detect the strong beat¬ 
ings of that organ in the previous days of his sickness. The 
faeces are of a dark coloration, and when at a later period 
they are extracted from the rectum they are mixed with 
dark blood. Rectal examination reveals toward the cascum 
a large tumor which is suspected to be an aneurism of the 
posterior aorta, or one of its branches. The horse dies sud¬ 
denly. At the post-mortem the following lesions are found: 
\ rupture of the rectum of recent date; nothing peculiar in 
• the chest, except the heart, whose left ventricle has its endo¬ 
cardium covered with rough, red and irregular granulations,
