OF DISLOCATIONS.

WHEN a. bone is moved out of its place or articulation so as toimpede its proper functions, it is said to be luxated or dislocated. Asthis often happens to persons in situations where no medical assistancecan be obtained, by which means limbs, and even lives, are frequentlylost we shall endeavour to point out the method of reducing the mostcommon luxations, and those which require immediate assistance. Anyperson of common sense and resolution, who is present when a disloca-tion happens, may often be of more service to the patient than the mostexpert surgeon can after the swelling and inflammation have come on.When these are present, it is difficult to know the state of the joint, anddangerous to attempt a reduction; and by waiting till they are gone oft,the muscles become so relaxed, and the cavity filled up, that the bonecan never afterwards be retained in its place

All that is necessary after reduction, is to apply cloths dipt in vinegaror camphorated spirits of wine to the part, and to keep it perfectly easy;and if any degree of inflammation remain, the application ot leechesis the best remedy. Many bad consequences proceed from the neglectof this rule A dislocation seldom happens without the tendons andligaments of the joint being strecthed and sometimes torn. When theseare kept easy till they recover their strength and tone, all goes on verywell- but if the injury be increased by too frequent an exertion of theparts, no wonder if they be found weak and diseased ever after.

DISLOCATION OF THE JAWS.

The lower jaw may be luxated by yawning, blows, falls, chewinghard substances, or the like. It is easily known from the patient'sbeing unable to shut his mouth, or to eat any thing, as the teeth of
