desired. Should the
liver be sluggish, mild alterative doses of the grey powder may be
sprinkled upon the food, and will thus be taken without the necessity of
forcing the animal. When the measures recommended do not succeed, the
appearance of the patient must direct those which are next to be adopted.
Where weakness prevails, and shivering denotes the presence of fever,
quinine and the sulphate of iron are required. Small blisters, or mustard
poultices, to the chest, may with due caution be applied. An emetic may
even be administered; but, if repeated at all, it must be only after two
or three days have elapsed. Where the system is vigorous, expectorants
and sedatives, with leeches to the chest, may be used. Turpentine liniment
to the sides, throat, and under the jaws, may also be freely rubbed in,
and the diet in quantity restricted. Tartar emetic in very minute doses
may be exhibited three times daily.

[Illustration: INFLAMMATION OF THE LUNGS.]

The chest of the dog is not in any remarkable degree the seat of disease.
The ribs of the animal being constructed for easy motion, and the muscles
which move them being strong and large in proportion to the size of the
bones, the lungs, therefore, are in general properly expanded; and this
circumstance tends to preserve them in a healthy condition. They do not,
however, always escape, but are subject to the same inflammations as those
of the horse, though, from the causes stated, more rarely attacked.

INFLAMMATION OF THE LUNGS is denoted by a quickened pulse and breathing,
preceded by shivering fits. The appetite does not always fail; in one or
two instances I have seen it increased; but it is most often diminished.
The animal is averse to motion; but when the affection is established, the
dog sits upon its hocks, and wherever it is placed, speedily assumes that
position. As the disorder becomes worse, the difficulty of breathing is
more marked. The creature also shows a disposition to quit the house, and
if there be an open window it will thrust its head through the aperture.
The sense of suffocation is obviously present, and at length this becomes
more and more obvious. The dog in the very last stage refuses to sit, but
obstinately stands. One of the legs swells, and, on being felt, it is
ascertained to be enlarged by fluid. There is dropsy of the chest, and the
limb has sympathized in the disposition to effusion. The pulse denotes the
weakness of the body; but the exc
