meness, but also renders weaker that side of the hoof in which
it occurs.

The only method of treatment that can be practised, therefore, is that of
palliation. Seeing that the trouble the veterinary attendant will have to
deal with is loss of a portion of the weight-bearing surface, his attention
is immediately directed to the shoeing. As with sand-crack, so with false
quarter, the frog and the bars must be called upon to take more of the
body-weight than commonly they do with the ordinary shoe. The indication,
then, is a bar shoe. At the same time, the bearing of the wall on the shoe
on either side of the fissure should be eased by slightly paring it, and
the hypertrophied horn on the outer surface of the wall removed with the
rasp.

In cases where penetration of the sensitive structures has occurred,
complicated with the formation of pus, the same treatment as for
complicated crack is to be followed. The foot should be poulticed for
several days with hot antiseptic dressings, and thorough cleansing of the
infected parted brought about. Afterwards strong solutions of suitable
antiseptics should be applied daily until such time as the horny covering
has renewed itself. This done and the bar shoe applied, the fissure may be
plugged with any effectual stopping. Either a mixture, such as Percival's,
of pitch 2 parts, tar 1 part, and resin 1 part, melted and mixed together,
or one of the artificial hoof-horns may either be used with advantage.

E. ACCIDENTAL TEARING OFF OF THE ENTIRE HOOF.

_Causes_.--Seeing that this accident to, and consequent severe wounding of,
the keratogenous membrane nearly always occurs in but one way, it is worthy
of special mention. So far as we are able to ascertain, it is an accident
peculiar to horses continually engaged in shunting operations either in
pits or station-yards. At the moment the animal is released from the waggon
he has been pulling, and should turn to the right or the left in order
to allow it to pass him, the shoe either becomes wedged in between two
converging rails, or is trapped by the wheel of the waggon. Either the
approaching waggon with the added weight its impetus gives it then pushes
the animal suddenly away, leaving a part of his foot still fixed to the
rails, or the animal himself, feeling securely held, makes a sudden effort
to release himself, and draws his foot cleanly out of the imprisoned horny
box.

The author calls to mind a case in which entire removal
