t. They then act as foreign
bodies, and inflame the parts adjacent to them. Should that inflammation
not be attended to, it extends, first involving the bones of the lower
jaw, and afterwards the gums, and CANKER OF THE MOUTH is established.

Such is the course of the disease, the symptoms of which are redness and
swelling during the commencement. Suppuration from time to time appears;
but as the animal with its tongue removes the pus, this last effect may
not be observed. The enlargement increases, till at last a hard body seems
to be formed on the jaw, immediately beneath the skin. The surface of the
gums may be tender, and bleed on being touched, but the tumor itself is
not painful when it first appears, and throughout its course is not highly
sensitive. At length it discharges a thin fluid, which is sometimes
mingled with pus, and generally with more or less blood. The stench which
ultimately is given off becomes powerful; and a mass of proud flesh grows
upon the part, while sinuses form in various directions. Hemorrhage now is
frequent and profuse, and we have to deal with a cancerous affection,
which probably it may not be in our power to alleviate. The dog, which
does not appear to suffer, by its actions encourages the belief that it
endures no acute pain--and for a length of time maintains its condition;
but, in the end, the flesh wastes and the strength gives way; the sore
enlarges, and the animal may die of any disease to which its state
predisposes it to be attacked.

The treatment consists in searching for any stump or portion of tooth that
may be retained. All such must be extracted, and also all the molars on
the diseased side, without any regard to the few which may be left in the
jaw. This done, the constitution must be strengthened, and pills, as
directed, with the liquor arsenicalis, should be employed for that
purpose.

Iodide of iron One to four grains.
Powdered nux vomica A quarter of a grain to one grain.
Salicine One to four grains.
Extract of gentian Three to twelve grains.
Powdered quassia As much as may be required.

The above forms one pill, three or four of which should be given daily,
with any other medicine which the case may require.

To the part itself a weak solution of the chloride of zinc may be used;
but nothing further should be done until the system has been invigorated,
and the health, as far as possible, restored. That be
