MIX in a large bottle, with a quart of soft water, two and a half ounces of common aquafortis, and, adding gradually the same quantity of litharge, slightly cork the bottle, occasionally shake it, and keep it in a warm situation; after a few days the liquid may be poured into a deep earthen, leaden, or pewter vessel, in which the linnen to be dried, being first well washed, though not bleached, should be immersed for ten or twelve hours; being then taken out and three times washed and rinsed in cold water, it is to be dipped in a weak solution of common glue, again rinsed and hung in a shade to dry.

It is now to be immersed for eight or ten hours, in a liquid composed of three quarters of an ounce each of copperas, or vitriol of iron, and common salt, dissolved in a quart of hot water, after which it is to be again washed, rinsed, and hung to dry in the shade.
