_Treatment._--In treatment the first step is to ascertain and remove the
cause whenever possible. If there is much local heat and inflammation, a
laxative (5 drams aloes or 1 pound Glauber's salt) may be given, and for
the pampered animal the grain should be reduced or replaced altogether
by bran mashes, flaxseed, and other laxative, nonstimulating feed. In
the debilitated, on the other hand, nutritious food and bitter tonics
may be given, and even a course of arsenic (5 grains arsenic with 1 dram
bicarbonate of soda daily). When the legs swell, exercise on dry roads,
hand rubbing, and evenly applied bandages are good, and mild
astringents, like extract of witch-hazel, may be applied and the part
subsequently rubbed dry and bandaged. If there is much heat but unbroken
skin, a lotion of 2 drams sugar of lead to 1 quart of water may be
applied on a thin bandage, covered in cold weather with a dry one. The
same may be used after the cracks appear, or a solution of sulphurous
acid 1 part, glycerin 1 part, and water 1 part, applied on cotton and
well covered by a bandage. In case these should prove unsuitable to the
particular case, the part may be smeared with vaseline 1 ounce, sugar of
lead 1 dram, and carbolic acid 10 drops.

INFLAMMATION OF THE HEELS WITH SEBACEOUS SECRETION (GREASE, OR CANKER).

This is a specific affection of the heels of horses usually associated
with the growth of a parasitic fungus, an offensive discharge from the
numerous sebaceous glands, and, in bad cases, the formation of red, raw
excrescences (grapes) from the surface. It is to be distinguished (1)
from simple inflammation in which the special fetid discharge and the
tendency to the formation of "grapes" are absent; (2) from horsepox, in
which the abundant exudate forms a firm, yellow incrustation around the
roots of the hair, and is embedded at intervals in the pits formed by
the individual pocks, and in which there is no vascular excrescence; (3)
from foot scabies (mange), in which the presence of an acarus is
distinctive; (4) from lymphangitis, in which the swelling appears
suddenly, extending around the entire limb as high as the hock, and on
the inner side of the thigh along the line of the vein to the groin, and
in which there is active fever, and (5) from erysipelas, in which there
is active fever (wanting in grease), the implication of the deeper
layers of the skin and of the parts beneath giving a boggy feeling to
the parts, t
