ing_ in all. As soon as the sloughs separate
and a granulating surface forms, the ordinary treatment for a healing
sore is instituted. Any slough under which pus has collected should be
cut away with scissors to permit of free drainage.

An occlusive dressing of melted _paraffin_ has also been employed. A
useful preparation consists of: Paraffin molle 25 per cent., paraffin
durum 67 per cent., olive oil 5 per cent., oil of eucalyptus 2 per
cent., and beta-naphthol 1/4 per cent. It has a melting point of 48 C.
It is also known as _Ambrine_ and _Burnol_. After the burned area has
been cleansed and thoroughly dried, it is sponged or painted with the
melted paraffin, and before solidification takes place a layer of
sterilised gauze is applied and covered with a second coating of
paraffin. Further coats of paraffin are applied every other day to
prevent the gauze sticking to the skin.

An alternative method of treating extensive burns is by immersing the
part, or even the whole body when the trunk is affected, in a bath of
boracic lotion kept at the body temperature, the lotion being frequently
renewed.

If a burn is already infected when first seen, it is to be treated on
the same principles as govern the treatment of other infected wounds.

All moist or greasy applications, such as Carron oil, carbolic oil and
ointments, and all substances like collodion and dry powders, which
retain discharges, entirely fail to meet the indications for the
rational treatment of burns, and should be abandoned.

Skin-grafting is of great value in hastening healing after extensive
burns, and in preventing cicatricial contraction. The _deformities_
which are so liable to develop from contraction of the cicatrices are
treated on general principles. In the region of the face, neck, and
flexures of joints (Fig. 63), where they are most marked, the contracted
bands may be divided and the parts stretched, the raw surface left being
covered by Thiersch grafts or by flaps of skin raised from adjacent
surfaces or from other parts of the body (Fig. 1).

INJURIES PRODUCED BY ELECTRICITY

#Injuries produced by Exposure to X-Rays and Radium.#--In the routine
treatment of disease by radiations, injury is sometimes done to the
tissues, even when the greatest care is exercised as to dosage and
frequency of application. Robert Knox describes the following
ill-effects.

_Acute dermatitis_ varying in degree from a slight erythema to deep
ulceration
