reasy surface. It is used in the strength of 1 part of
bichlorid to 1,000 to 5,000 parts of water, according to the delicacy of
the tissue to which it is applied. (2) Carbolic acid in from 2 to 5 per
cent solution is used on infected wounds and for cleaning instruments,
dressings, and sponges. It unites well with oil and is preferred to the
bichlorid on a greasy surface. A 5 per cent solution in oil is often
used under the name of carbolized oil. (3) Aluminum acetate is an
efficient and cheap antiseptic, and is composed of 1 part alum and 5
parts acetate of lead, mixed in 20 parts of water. (4) Boric acid is
good, in a 2 to 4 per cent solution, to cleanse wounds and wash eyes.
Compound cresol may be used in a 1 to 3 per cent solution in water.
Iodoform is one of the most used of the antiseptics, and it also acts as
an anodyne, stimulates granulation, and checks wound secretion. A very
efficacious and inexpensive powder is made by taking 5 parts of iodoform
and 95 parts of sugar, making what is called iodoform sugar. Tannic acid
is a useful drug in the treatment of wounds, as it arrests hemorrhage,
checks secretion, and favors the formation of a scab. A mixture of 1
part tannic acid and 3 parts iodoform is good in suppurating wounds.
Iodol, white sugar, ground and roasted coffee, and powdered charcoal are
all used as protectives and absorbents on suppurating surfaces. More
depends on the care and the method of application of the drug than on
the drug itself. On aseptic wounds use only those antiseptics that do
not irritate the tissue. If care is used in the application of the
antiseptic, corrosive sublimate or carbolic acid is to be recommended.
In order to keep air from the wound and to absorb all wound secretions
rapidly, a dressing should be applied. If the wound is aseptic, the
dressing should be likewise, such as cotton gauze, sterile cotton,
oakum, or tow. This dressing should be applied with uniform pressure at
all times and secured by a bandage. Allow it to remain for a week or ten
days if the wound is aseptic or if the dressing does not become loose or
misplaced or become drenched with secretions from the wound, or if pain,
fever, or loss of appetite does not develop. The dressing should then be
removed, the wound treated antiseptically, and a sterilized dressing
applied.

HEALING UNDER A SCAB.

This often occurs in small superficial wounds that have been kept
aseptic. In order that a scab may form, the wound
