A Plaster for Sprains or Attacks of Rheumatism in Joints

Take equal parts of resin and Burgundy pitch, melt in a tin dipper, and when liquid put in a piece of camphor gum as large as an English walnut, and half that, in size, of opium. Stir till all is dissolved, as it will soon be if kept hot, and when none of the gum is visible spread on thin leather or thick drilling. Apply while warm and it will relieve the pain. These are all excellent, tried remedies.
