those used to eat off proud or fungous flesh; such as are all the caustics.

PHAGEDENIC Water, in chemistry, denotes a water made from quicklime and sublimate; and is very efficacious in the cure of phagedenic ulcers. To prepare this water, put two pounds of fresh quicklime in a large earthen pan, and pour upon it about ten pounds of rain-water; let them stand together for two days, stirring them frequently; at last leave the lime to settle well, then pour off the water by inclination, filtrate it, and put it up in a glass bottle, adding to it an ounce of corrosive sublimate in powder; which from white becomes yellow, and sinks to the bottom of the vessel. The water being settled, is fit for use in the cleansing of wounds and ulcers, and to eat off superfluous flesh, and especially in gangrenes; in which case may be added to it a third or fourth part of spirit of wine.
