oot. The coronary band becomes hot, swollen, and painful, and after two
or three days the horn separates from the band and slight suppuration
follows. For a few days the animal is lame, but as the suppuration
disappears the lameness subsides. New horn, often of an inferior
quality, is produced by the coronary band, and in time the cleft is
grown off and complete recovery is effected. The frog is occasionally
frostbitten and may slough off, exposing the soft tissues beneath and
causing severe lameness for a time.

_Treatment._--Simple frostbites are best treated by cold fomentations
followed by applications of a 5 per cent solution of carbolized oil.
When portions of the skin are destroyed, their early separation should
be hastened by warm fomentations and poultices. Ulcers are to be treated
by the application of stimulating dressings, such as carbolized oil, a 1
per cent solution of nitrate of silver or of chlorid of zinc, with pads
of oakum and flannel bandages. In many of these cases recovery is
exceedingly slow. The new tissue by which the destroyed skin is replaced
always shrinks in healing, and, as a consequence, unsightly scars are
unavoidable. When the coronary band is involved it is generally
advisable to blister the coronet over the seat of injury as soon as the
suppuration ceases, for the purpose of stimulating the growth of new
horn. Where a crevasse is formed between the old and the new horn no
serious trouble is liable to be met with until the cleft is nearly grown
out, when the soft tissues may be exposed by a breaking off of the
partly detached horn. But even if this accident happens final recovery
is effected by poulticing the foot until a sufficient growth of horn
protects the parts from injury.

QUITTOR.

Quittor is a term applied to various affections of the foot wherein the
tissues which are involved undergo a process of degeneration that
results in the formation of a slough followed by the elimination of the
diseased structures by means of a more or less extensive suppuration.

For convenience of consideration quittors may be divided into four
classes, as suggested by Girard: (1) Cutaneous quittor, which is known
also as simple quittor, skin quittor, and carbuncle of the coronet; (2)
tendinous quittor; (3) subhorny quittor; and (4) cartilaginous quittor.

CUTANEOUS QUITTOR.

Simple quittor consists in a local inflammation of the skin and
subcutaneous connective tissue on some part of the c
