Styptic Water.
Take of blue vitriol and alum, each an ounce and a half; wet water, one pint. Boil them until the salts are dissolved, then filter the liquor and add to it a drachm of the oil of vitriol.
This water is used for stopping a bleeding at the nose, and other haemorrhages; for which purpose cloths or duffils dipt in it must be applied to the part.
