HOW TO MAKE A SLING (SCUDDER).

The above illustration shows sling in position. It is made of cotton
cloth a yard square cut diagonally from corner to corner.]

A fall from a chair or bed is sufficient to cause the accident. A
child generally cries out on movement of the arm of the injured side,
or on being lifted by placing the hands under the armpits of the
patient. A tender swelling is seen at the point of the injury of the
collar bone. A broad cotton band, with straps over the shoulders to
keep it up, should encircle the body and upper arm of the injured
side, and the hand of the same side should be supported by a narrow
sling fastened above behind the neck.

=LOWER-JAW FRACTURE.=

_First Aid Rule.--Put fragments into place with your fingers, securing
good line of his teeth. Support lower jaw by firmly bandaging it
against upper jaw, mouth shut, using four-tailed bandage. (Fig. 12.)_

Fracture of the lower jaw is caused by a direct blow. It involves the
part of the jaw occupied by the lower teeth, and is more apt to occur
in the middle line in front, or a short distance to one side of this
point. The force causing the break usually not only breaks the bone,
but also tears the gum through into the mouth, making a compound
fracture. There is immediate swelling of the gum at the point of
injury, and bleeding. The mouth can be opened with difficulty.

The condition of the teeth is the most important point to observe.
Owing to displacement of the fragments there is a difference in the
level of the teeth or line of the teeth, or both, at the place where
the fracture occurs. Also one or more of the teeth are usually
loosened at this point. In addition, unusual movement of the
fragments may be detected as well as a grating sound on manipulation.

=Treatment.=--The broken fragments should be pressed into place with
the fingers, and retained temporarily with a four-tailed bandage, as
shown in the cut. Feeding is done through a glass tube, using milk,
broths, and thin gruels. A mouth wash should be employed four times
daily, to keep the mouth clean and assist in healing of the gum. A
convenient preparation consists of menthol, one-half grain; thymol,
one-half grain; boric acid, twenty grains; water, eight ounces.
