sure of success, operative measures may be
determined on.

In this case the author's practice has been, after casting the animal, to
apply a tourniquet to the limb and proceed to excision. A lozenge-shaped
incision, extending to near but not quite the circumference of the
swelling, should be made with a large knife right through the skin and
deeply into the growth. The whole is then removed, proceeding in an
excavating manner under the thickened skin at the margin. Haemorrhage,
though proceeding from several apparently large vessels in the structure of
the tumour, and oozing generally over the whole of the outer surface,
is rarely profuse enough to interfere with the operation, and is easily
controlled by cold water douches and the application of the artery forceps
to one or more of the larger vessels. The operation completed, the larger
bleeding-points should be secured by exerting torsion with the artery
forceps, and the surface oozing stayed by frequent dashing with cold water.

When the haemorrhage has sufficiently ceased, an ordinary flat firing-iron
should be passed over the whole of the cut surface, and an effectual eschar
formed.

Following this, and _before removing the tourniquet_, the wound should be
filled with pledgets of carbolized tow, and the whole tightly secured by a
stout and broad linen bandage of not less than 6 yards in length.

_Reported Case_.--'The patient, a middle-aged cart mare, had a pair of
fore-feet the like of which I never saw. As the result of long-standing and
imperfectly-treated quittor all over the seat of side-bone on the outer
side of each fore-foot, beginning pretty far forward, and extending to the
heel on the inner side, filling up the hollow and reaching nearly to the
fetlock, was a big, bulging, hard, calloused enlargement or tumour standing
out 3 or 4 inches all round, covered with thick horny skin and stubby hair,
and having on its surface the small openings of several sinuses leading
deeply down to the ossified and diseased cartilage underneath. And yet
with all this diseased undergrowth the mare, strangely enough, walked and
trotted sound. I was told that this mare had been troubled with suppurating
corns and quittor, that many unsuccessful attempts had been made at cure,
but that, getting worse instead of better, these tumours had formed.

'After casting and anaesthetizing, a strong rubber tourniquet was placed
above the knee and the operation commenced. With a surgeon
