d conduces to the eruption. Lastly, any sudden change of feed
may induce it.

The blisters may in part go on to suppuration so that vesicles and
pustules often appear on the same patch, and, when raw from rubbing,
the true nature of the eruption may be completely masked. In well-fed
horses, kept in close stables with little work, eczema of the limbs may
last for months and years. It is a very troublesome affection in draft
stallions.

_Treatment._--This disease is so often the result of indigestion that a
laxative of 1 pound Glauber's salt in 3 or 4 quarts water or 1-1/2 pints
olive oil is often demanded to clear away irritants from the alimentary
canal. Following this, in recent and acute cases, give 2 drams of
acetate or bicarbonate of potash twice a day in the drinking water. If
the bowels still become costive, give daily 1 ounce sulphate of soda and
20 grains of powdered nux vomica. In debilitated horses combine the nux
vomica with one-half ounce powdered gentian root. As a wash for the skin
use 1 dram bicarbonate of soda and 1 dram carbolic acid in a quart of
water, after having cleansed the surface with tepid water. Employ the
same precautions as regards feeding, stabling, and care of harness as in
simple congestion of the skin.

In the more inveterate forms of eczema more active treatment is
required. Soak the scabs in fresh sweet oil, and in a few hours remove
these with tepid water and Castile soap; then apply an ointment of
sulphur or iodid of sulphur day by day. If this seems to be losing its
effect after a week, change for mercurial ointment or a solution of
sulphid of potassium, or of hyposulphite of soda, 3 drams to the quart
of water. In these cases the animal may take a course of sulphur (1
ounce daily), bisulphite of soda (one-half ounce daily), or of arsenic
(5 grains daily) mixed with 1 dram bicarbonate of soda.

INFLAMMATION WITH PUSTULES.

In this affection the individual elevations on the inflamed skin show in
the center a small sac of white, creamy pus, in place of the clear
liquid of a blister. They vary in size from a millet seed to a hazelnut.
The pustules of glanders (farcy buds) are to be distinguished by the
watery contents and the cordlike swelling, extending from the pustules
along the line of the veins, and those of boils by the inflammation and
sloughing out of a core of the true skin. The hair on the pustule stands
erect, and is often shed with the scab which results. When itchin
