EPIDEMIC DISEASE IN CATTLE.

on the removal of the horn ecchymosed spots were found on 
some parts of the sensible laminae, and considerable extravasation 
of blood in other parts of the foot, particularly on the coronary 
portion of the heel. Emollient poultices and soothing remedies 
were applied locally, and vegetable tonics with opium adminis- 
tered. On the following morning the animal appeared a little re- 
lieved. 
Mr. Brining being determined, if possible, to find out the cause 
of the extravasation, the parts were more minutely examined, and, 
exactly in the centre of the heel, where the incision had been 
made by the first surgeon, and which had apparently almost all 
healed by the first intention, a small orifice was perceived, through 
which a portion of coagulated blood was protruding. Finding 
that the heel was filled with coagulum, mixed with flakes of fibrin, 
the aperture , was enlarged, and three-quarters of a pound of 
coagulum was extracted. It was of a dark hue, foetid, and ap- 
peared to have been extravasated for some time. How it had got 
there was the question ; but one thing was certain, that it was 
acting as a source of irritation, and consequently its removal was 
determined on ; after which the foot was again poulticed, cooling 
lotions applied, &c., when in about five or six hours a messenger 
came with the information that the cow was bleeding to death. 
Mr. Brining immediately went, and found alarming haemor- 
rhage, evidently from the posterior mesian artery. The blood 
jerked out as fast as it does when a horse is bled with a large 
fleam in the neck. The actual cautery was tried, in order to 
arrest the hemorrhage, but it could not be effected. All attempts 
to get at the bleeding vessel were fruitless, from the swelling 
around the part. The hole made by the incision from which 
at first blood was abstracted, and from which the present hemor- 
rhage issued, was plugged with tow and pressure applied, which 
with difficulty arrested the stream. The loss of blood excited the 
animal, and added to its existent debility. 
Wishing to get the foot into the suppurative stage, and being 
prevented from applying our remedies in consequence of the 
bleeding, what was the best plan to put a stop to it ? Pressure 
was tried, but every time the pressure was removed there was 
as much bleeding as before. An artery, and one of no small size, 
had been wounded, but howl and when? 
Mr. Brining recommended to the owner to place a ligature on 
the metatarsal artery before its bifurcation, to which the owner 
would not consent until he had farther advice. Accordingly Mr. 
Matthew Lucas came over, and recommended the operation, after 
having removed the tow, &c. and seeing the haemorrhage. On 
the next day Mr. Robert Lucas came and recommended a fair
