almost sure to follow) by giving three times a day saltpeter 1 ounce and
iodid of potash 1 dram, and by the application of mustard or blisters
over the abdominal walls. Tonics, mineral and vegetable, are also
indicated. Probably the best tonic is one consisting of powdered
sulphate of iron, gentian, and ginger in equal parts; a heaping
tablespoonful of the mixture is given as a drench or mixed with the
feed, twice a day. Good nutritious feeds and gentle exercise complete
the treatment.

DISEASES OF THE LIVER.

In the United States the liver of the horse is but rarely the seat of
disease, and when we consider how frequently the liver of man is
affected this can not but appear strange. The absence of the gall
bladder may account to a certain extent for his freedom from liver
diseases, as overdistention of this and the presence in it of calculi
(stones) in man is a frequent source of trouble. In domestic animals, as
in man, hot climates tend to produce diseases of the liver, just as in
cold climates lung diseases prevail. Not only are diseases of the liver
rare in horses in temperate climates, but they are also very obscure,
and in many cases pass totally unobserved until after death. There are
some symptoms, however, which, when present, should make us examine the
liver as carefully as possible. These are jaundice (yellowness of the
mucous membranes of the mouth, nose, and eyes) and the condition of the
dung, it being light in color and pasty in appearance.

HEPATITIS, OR INFLAMMATION OF THE LIVER.

This disease may be general or local, and may assume an acute or chronic
form.

_Symptoms._--The symptoms of acute hepatitis are: Dullness; the horse is
suffering from some internal pain, but not of a severe type; constipated
and clay-colored dung balls; scanty and high-colored urine; and general
febrile symptoms. If lying down, he is mostly found on the left side;
looks occasionally toward the right side, which, upon close inspection,
may be found to be slightly enlarged over the posterior ribs, where pain
upon pressure is also evinced. Obscure lameness in front, of the right
leg mostly, may be a symptom of hepatitis. The horse, toward the last,
reels or staggers in his gait and falls backward in a fainting fit,
during one of which he finally succumbs. Death is sometimes due to
rupture of the enveloping coat of the liver or of some of its blood
vessels.

_Causes._--Among the causes that lead to this disease w
