applications. Both objects, however, can be attained by judiciously
combining the curative agents with such substances as will at the same time
cleanse the parts.

In the vesicular stage, when the skin is feverish and the epidermis peeling
off, thus exposing the exuding dermis, an application of boric-acid
solution, 2 drams of the acid to 8 ounces of water, often relieves the
smarting or itching, and also serves to check the exudation and dry the
surface. If this fails to have the desired effect compound cresol, 1 ounce
to 2 quarts of water, should be used as a wash. Either of these washes may
be used several times a day until incrustation is well established. Then
compound cresol, 1 ounce to 2 quarts of sweet oil, or the benzoated oxid of
zinc ointment, giving the affected surfaces a thorough application once a
day, will be efficacious. When the eczema is not the result of an external
irritant, it takes usually from one to two weeks to heal.

In chronic eczema, when there is a succession of scabs or scales, indolent
sores or fissures, the white precipitate ointment, nitrate of mercury
ointment, or blue ointment, mixed with equal parts of cosmoline or fresh
lard, may be applied every second day, taking care to protect the parts so
that the animal can not lick it off.

The internal administration of arsenic often yields excellent results in
chronic eczema. Dissolve 1 dram of arsenic and 1 dram of carbonate of
potassium in 1 pint of boiling water, and give 1 ounce of this twice a day
in water, after feeding. An alkali internally may be of service. As such,
one may give 2 ounces of bicarbonate of soda twice daily. Sublimed sulphur
may also be tried in ounce doses twice daily.

PUSTULES (IMPETIGO).

Impetigo is an inflammatory disease of the skin, characterized by the
formation of distinct pustules, about the size of a pea or a bean, without
itching. The pustules develop from the papular layer of the skin, and
contain a yellowish-white pus. After reaching maturity they remain
stationary for a few days, then they disappear by absorption and dry up
into crusts, which later drop off, leaving upon the skin a red spot that
soon disappears. Occasionally the crusts remain firmly adherent for a long
time, or they may be raised and loosened by the formation of matter
underneath. The dry crusts usually have a brown or black appearance.
