“ The simplest, the cleanest, and most efficacious for ordinary purposes, we believe to be the following: Take a piece of soft flannel, dip it in boiling water, wring it out immediately, and sprinkle one side of it with fresh flour of mustard. The flannel should be laid upon a hot plate while being sprinkled, that no warmth may be lost. Another way of making a mustard poultice is by spreading a large tablespoonful of mustard, made in the ordinary way as if for table, on a piece of soft linen, and warming it before the fire when it is to be applied. ”
