n and a quantity of it
is poured upon a suitable piece of aseptic gauze or cotton and this is
contacted with the wound. The extremity is carefully bandaged and this
dressing is left in position for forty-eight hours unless there occurs,
in the meanwhile, evidence of profuse suppuration--which is unusual.

One is to be guided as to the progress made by the degree of lameness
present. If little or no lameness develops, it is reasonable to expect
that infection has been checked; that the wound is dry and redressing
every second day is sufficiently frequent.

Where cases progress favorably, recovery (unless infectious arthritis
results) should occur in from ten days to three weeks. Where extensive
sub-coronary fistulae result, either from lack of prompt or proper
attention, the condition is then one requiring a radical operation to
establish drainage and to disinfect if possible, the suppurating
tissues.

Corns.

Etiology and Occurrence.--In horses, because of a tendency toward
contraction of the heel in some subjects, together with work on hard
roads and pavements, where the feet become dry and brittle, and because
of neglect of the matter of shoeing, this affection is of frequent
occurrence. Unshod horses are rarely affected. If conformation is faulty
and too much weight is borne on the inner or the outer quarter, and the
hoof wall at the quarter tends to turn inward, corns are usually
present. They occur more frequently on the inner quarters of the front
feet, though the outer quarters are occasionally also affected and in
rare instances corns are found at the toes. They do not often affect the
hind feet.

As soon as injury by pressure, such as is supposed to cause the
formation of corns, is brought to bear on the sensitive sole, an
extravasation of blood occurs. In time when the cause remains active,
this discoloration is evident in the substance of the insensitive sole
and consists in a red or yellowish spot which varies in size--this is
ordinarily termed dry corn.

In some cases where infection of this extravasation of blood and serum
occurs, instead of desiccation and discoloration of the insensitive
parts, there is, in time, manifested a circumscribed area of destruction
of the insensitive sole and the abscess may, where no provision for
drainage exists, burrow between sensitive and insensitive laminae and
perforate the tissues at the coronet. If the suppurative material
discharges readily by way of the so
