“Elevate the injured joint and wrap in cloths wrung out in cold water. The picture shows how to keep the cloths constantly wet without having to change them. A jug of water [is] placed higher than [the] injured limb, and a strip of linen with one end in the jug and the other end resting upon the wrapping of the sprained joint, is all that is necessary. The water will pass from jug to compress by way of the linen strip.”
