2482. Dr. Ure's Ink
For twelve gallons of ink take twelve pounds of bruised galls, five pounds of gum, five pounds of green sulphate of iron, and twelve gallons of rain-water. Boil the galls with nine gallons of the water for three hours, adding fresh water to supply that lost in vapour; let the decoction settle, and draw off the clear liquor. Add to it the gum, previously dissolved in one and a half gallons of water; dissolve the green vitriol separately in one and a half gallons of water, and mix the whole.
