The best tourniquet for ordinary use is that known as Petits, Fig. Petit*8 tourniquet. from having been introduced by the celebrated French surgeon ofthat name. It consists of two metal plates, the distance betweenwhich is regulated by a screw, with a strong linen or silk strapprovided with a buckle.
