le, no disturbance of the heel or
quarters occurs above the hoof.

Symptomatology.--A supporting-leg-lameness characterizes this
condition; and this lameness in most instances varies in degree with the
amount of distress which is occasioned by pressure upon the inflamed
parts. By an examination of the sole after having removed all dirt, and
exposed the horny sole to view, no difficulty is encountered in locating
the cause of the trouble.

Treatment.--Before suppuration has taken place and in the cases where
suppuration does not occur, the horse-shoer's method of paring out the
diseased tissue affords a means of temporary relief; but unless
frequently done, in many cases, lameness results within about three
weeks after such treatment has been given. In other instances temporary
relief is not to be gotten in this manner for any great length of time
or until a more rational mode of treatment becomes necessary so that the
subject may experience a cessation of the inconvenience or distress.

The general plan which meets with the approval of most practitioners
consists in careful leveling of the foot and removing enough of the wall
and sole at the quarters to make possible frog pressure by means of a
bar shoe. With frog pressure, expansion of the heel follows in time, and
permanent relief is obtainable in this manner. Thinning the wall of the
quarter is advocated by many practitioners and is undoubtedly beneficial
in chronic cases where marked contraction has taken place. The wall must
be thinned with a rasp until it is readily flexible by compressing with
the thumbs.

There are instances, however, where corns and contraction of the heel
have existed so long that they do not yield to treatment. Such cases are
found in old light-harness or saddle-horses that have been more or less
lame for years and where there exists marked contraction of the heels,
rough hoof walls, and hard and atrophied frogs.

Suppurating corns require surgical attention in the way of removal of
the purulent necrotic mass and making provision for drainage. Dry
dressings, such as equal parts of zinc sulphate and boric acid, may be
employed to pack the cavity. After the infectious condition has been
controlled, and the wound is dry, the same plan of treatment is
indicated that is employed in the non-suppurating corn. Ample time is
allowed, however, for the surgically invaded tissues to granulate and,
if the subject is to be put in service, a leather pa
