This may at first attract no notice; after it has been submitted to for a
week, add to every three pints an extra pint of turpentine, which will
soon banish all the philosophy the strongest-minded dog may have at his
command. Even subsequent to the period when the application of the
liniment is received with the acutest and most piteous cries, the torture
must be continued until the skin, being reduced to its natural thickness,
announces that its office is perfected; only, with the production of this
last effect, the agent that gives such pain should be used less lavishly.

During the application of the liniment, some diluted liquor arsenicalis
may also be administered, and even the pills containing iodide of sulphur
exhibited.

The fourth kind of mange is where the hair falls suddenly off in circular
patches. For this any simple ointment, as the ung. cest. or no application
at all is sufficient.

The fifth kind is the worst, especially where it attacks young pups.
Almost all the hair falls off; and the poor little creature is thin, and
nearly naked, while the surface of the body is covered with dark patches,
and comparatively large pustules. If the dark patches be punctured, a
quantity of venous and grumous blood exudes; but the wound soon heals. In
full-grown dogs, the same form of disease seldom involves more than the
top of the head, neck, and the entire length of the back; but it is
precisely of the self-same character as in the more juvenile animal.

In both cases the treatment is the same. The dark pustules are to be cut
into, which produces no pain; and the pustules are to be freely opened,
which operation is attended with no apparent effects. The bare skin is to
be then washed tenderly with warm water and a soft sponge, after which the
body may be lightly smeared over with the ointment of camphor and mercury;
see p. 265. This operation must be repeated daily. The liquor arsenicalis
may be administered as drops, and pills of the iodide of sulphur likewise
exhibited.

Where the dog is old, a cure invariably results; but it takes time to
bring it about. Perhaps months may be thus consumed; and the practitioner
will require a goodly stock of patience before he undertake the treatment
of such a case. The proprietor, therefore, must be endowed with some
esteem for the animal, before he can be induced to pay for all the physic
it will consume. I cannot
