ZINC OR CALAMINE POWDER.
This made into an ointment is valuable for healing. Take five ounces of lard, one ounce of rosin, melt them together and when these begin to get cool, stir in 2 ounces of calamine, finely powdered. If the wound is not healthy, a small quantity of common turpentine may be added. This salve justly deserves the name of healing ointment. The calamine is sometimes sprinkled with advantage on cracked heels.
