To clear the Eye-sight.

℞ Rain water of the clearest you can get one gallon, let it settle and clear by it self at least one day and night, and after put it into a fair bason of earth glased, or of silver, then put thereto of Roch Allom, the bigness of a Pigeons Egg, and and a quarter of as much white Coperas, and let them stand 24 houres well covered, then scum it clean with a feather, and drein it into another bason; then take away the scum, and the grounds, and so doe it every 24 hours, till it be clear without scum or grounds, and when it is perfectly purified, put it into a full pint of the best Rosewater which is white, and put it into a good big glasse, then set it in the Sun thirty dayes or more. Afterwards take it in, and wash your eyes with it three or four times in a week, when you are in bed, or oftner till you bee eased; when you wash your eyes, lye upon your back, that it may the better soke into them, and if it be too sharp, then abate it, by mingling some spring water with it. The best time to make it is in Aprill or May; but if need be at any time in the Summer.

If you take the rain-water in glasses, or glased earthen pans as it falleth from heaven, free from durt, sand, or other filth, that will be much better.
