Of Natural and Supernatural Things Also of the first...

Take and give two drops at the beginning and entrance of the Spring, and in the beginning or entrance of Autumn likewise two drops; every one that so takes it, is freed, and well preserved from unhealthful and infectious Air, except the Disease were by Almighty God ordained for the death of the party.

In the Name of God, take very pure, fine, refined Gold, as much as you will, or think to be sufficient, dissolve it in a rectified Wine, as is usual to make Aqua vitæ; after solution of the Gold, set it a Moneth in digestion; this distil in a Bath very slow and gently, distil the Spirit of Wine divers times from it, so long till you see your Gold lie at the bottom like a Juice: This is the true way and meaning of some of the Ancients, to prepare Gold. But I will shew and teach you a way much readier, better, and more beneficial; that in stead of this prepared Gold, you take one part of the Mercury of Gold, as I have taught the making of it in another place; abstract from it its water of Airiness, that it may be a subtle Dust, and take two parts of our blessed Oil, poure the Oil very slowly upon the Dust of the Mercury of Gold, till all be in it, set it in a Vial well sealed, in the heat of the first degree of the secret Furnace; therein let it stand ten dayes and nights, your Powder and Oil will be quite dry, of a black gray colour.

After ten days give it the heat of the second degree, the gray and black colour will by little and little become white, till at last it will be of a heavenly white, and at the end of the ten days it will begin to be of a pure red, but let not this trouble you; for all these Colours proceed only from the Mercury of Gold, which swallowed up our blessed Oil, and now conceals in the innermost part of its Body; but our Oil will conquer this Mercury of Gold by the power of the fire, and cast it forth from within, and the Oil will predominate over it with its hot red Colour, and be continually outwards. And therefore it will be time, after the expiration of twenty days, that you open the window of the third degree, wherein the external white Colour and Power will by little and little enter in into the inward part, and the internal red Colour will turn outward by the force of the fire. Keep this degree of heat ten days without diminution or augmentation of it, you will see a Powder which before was white, to be now very red, but let not redness trouble you, for 'tis yet unfix'd and volatile. And after these ten days are ended, thirty days being in all expired, then open the last window of the last degree of fire, keep it ten days in this degree, this high red pouder will then begin to flux, let it stand so in flux the ten days, then take it out, you will find at the bottom a very high, red, transparent stone of a Ruby Colour, flux'd according to the form of the Glass, as is taught in the Treatise of Vitriol, wherewith you may make projection.
