To Prepare Fumigating Powder
Take equal parts of cascarilla bark, in coarse powder, camomile flowers, and anise-seed, powdered and well mixed together. Two ounces of each will be sufficient to use for several times. Take up some hot coals upon a shovel, and sprinkle the powder over them very slowly; and as the smoke arises, carry the shovel into all parts of the room, and fumigate the air thoroughly. It destroys all disagreeable odors, and is said to prevent contagion in infectious diseases, such as diphtheria, scarlet fever, and the like.
