rts by
weight. The blisters should be opened as soon as formed, to allow the
escape of the serum, followed by a wash composed of chlorid of zinc, 1 dram
to 15 ounces of water. When there is any formation of crusts, carbolized
cosmoline should be applied.

FURUNCULUS (BOILS).

This is an acute affection of the skin, usually involving its whole
thickness, characterized by the formation of one or more abscesses,
originating generally in a sebaceous gland, sweat gland, or hair follicle.
They usually terminate by absorption, or by the formation of a central
core, which sloughs out, leaving a deep, round cavity that soon heals.

_Causes._--Impoverished state of blood, the result of kidney diseases or of
local friction or contusions, with the entrance of pus cocci through the
damaged skin or through a hair follicle or a sebaceous gland.

_Symptoms._--Boils in cattle usually appear singly, not in clusters; they
may attain the size of a hen's egg. The abscess begins as a small round
nodule, painful on pressure, gradually increases in size until death of the
central portion takes place, then the surface of the skin gives way to
internal pressure and the core is released and expelled. Constitutional
symptoms are generally absent, unless the boils occur in considerable
numbers, or by their size involve a great deal of tissue.

_Treatment._--Poulticing to ripen the abscess. If this can not be done,
apply camphorated oil two or three times a day until the core is formed. As
soon as the central or most prominent part becomes soft, the abscess should
be opened to release the core. Then use carbolized cosmoline once a day
until the healing is completed. If the animal is in poor condition, give
tonics--copperas, gentian, ginger, and sulphur, equal parts by weight, 1
tablespoonful twice a day. If the animal manifests a feverish condition of
the system, give half an ounce of saltpeter twice a day, continuing it
several days or a week.

FAULTY SECRETIONS AND ABNORMAL GROWTHS OF THE SKIN.

PITYRIASIS (SEBORRHEA, DANDRUFF, OR SCURF).

This is a condition characterized by an excessive secretion of sebaceous
matter, forming upon the skin in small crusts or scales.

_Causes._--It is ascribable to a functional derangement of the sebaceous
glands, usually accompanied with dryness and loss of pliancy of the skin.
The animal is hidebound, as it is commonly termed, thin in flesh, inclined
to rub, and very frequently lousy. The condition
