The wonderful and true Water against Gangrenes.

℞ lb xx. of Rain or River water, put them in a great pew∣ter Bason, and throw therein iiij. pound of good unmixt or unal∣ter'd quick-lime, and let it by a slow ebullition softly quench it self without agitation, and when you shall perceive the extinction to be performed; and that the boyling and working of the Lime is over, add thereto ℥ ij. of Arsenick in powder, and ℥. j. of good well chosen Mastick also in powder, stir all together and mingle it conveniently with a wooden Spatula or Slice, then let it setle until the matter be well gathered in the bottom, and the water swimming over very clear: then pour out all the clear, decant∣ing it softly without stirring the bottom, and filtrate the remain∣der to join both again in a gray earthen Pan, adding to it ℥. ij. of corrosive Sublimate in powder, ℥ vj. very good spirit of wine well dephlegmated, and ʒ ij. good spirit of Vitriol; put all this mixture being yet unsetled in Glass bottles and keep it for use. If you make use of this water for any other purpose then for sore eyes, you must shake it and mix the bottom with the clear, and so use it against the Gangrene and all its accidents, the cure of old running sores, cancerous, sinuous and malignant Ulcers; a∣gainst all preternatural and painful outward heat, and against all external inflammations; against Phlegmon's, Erysipela's, burn∣ings and even arthritical pains proceeding from hot causes, and finally against inflamed and dolorous wounds. If it seems to be too strong or violent, let it be tempered by adding a greater quantity of spirit of Wine, or phlegm of Vitriol or Allom. But if you will use it for Ophthalmies, and small sores in the corners of the eyes or in the eyelids, you may temper it with water of juice of Plantain, or of great Celandine, or even with phlegm of Allom: but above all things, take care that the water you do

use for the eyes be well filtrated, and that no part of the setling in the bottom of the Glass should be mix'd with it; the applica∣tion of this water is commonly made with fillets of linnen cloth, and I may confidently assure, that those that shall make use there∣of, will find it an infallible and sure Remedy and almost of a wonderful successe in all the particulars we have spoken of.
