Take twelve pounds of bruised galls, five pounds of gum Senegal, five pounds of green sulphate of iron, and twelve gallons of rain water. Boil the galls with nine gallons of water for three hours, adding fresh water to replace what is lost by evaporation. Let the decoction settle, and draw off the clear liquor; add to it a strained solution of the gum; dissolve also the sulphate of iron separately, and mix the whole.
