Is made with a Band five Ells long, and two Fingers broad, roll'd with one Ball: The Application of it is begun with a Circumvolution at the lower part of the Humerus, it is pass'd over the Fold of the Arm; a Circumvolution is also form'd in the upper-part of the Elbow, and the Figure of KY in its Fold. Afterward the Rollers are continu'd upon the Elbow, and the KY's in the inside of the Arm, till the Elbow be entirely cover'd: The Band is likewise carry'd up to the top of the Arm with Rollers, and stay'd round about the Body. The Patient must be oblig'd to keep his Bed, or else his Arm may be put in a Scarf, after the same manner as in the Fracture of the Arm.

Of the Luxation of the Wrist.
If the Luxation be Internal, the Hand is turn'd back to the outside, so that for the Reduction thereof, it wou'd be requisite to cause the back of the Hand to be laid upon a Table, and the Extension to be made by drawing the Elbow and Hand, whilst the Surgeon takes care to press the Prominence.
If the Luxation be External, the Hand is bended on the inside; so that to reduce it, the inside of the Hand is to be laid upon a Table, and the Surgeon is to press it after the Extension.
If the Luxation be on the sides, the Hand is turn'd to one side; so that the Extension must be made, and the Hand turn'd on the side opposite to the Luxation. But the Fingers are usually drawn one after another, to the end that the Tendons may be set again in their Place.
The eight Bones of the Carpus may be in like manner dislocated both on the inside and without; and to set 'em right, the Hand is to be laid upon a Table, and the Extension to be made, so as to press the Protuberances on the inside, if the Luxation be internal, and on the outside if it be external.
