Two or more handkerchiefs must sometimes be applied, as in a broken collar-bone, or when it is necessary to keep dressings under the arm. The bandage is applied by knotting the opposite comers of one handkerchief together, and passing the left arm through it, then passing another handkerchief under the right arm, and tying it. By this means we can brace the shoulders well back, and the handkerchief will press firmly over the broken collar-bone: besides, this form of bandage does not readily slip or get slack, but it requires to be combined with the sling, in order to keep the arm steady.
