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. Praise God for such his high Revelation, and thank him for
ever, _Amen_.

_Its Multiplication._

The Ancient Wise, having found the Stone, and prepared it to a perfect
power, and mutation of the imperfect Metals into Gold, have a long time
enquired whether a thing were not to be found to augment the power of
the Stone; and they found two kinds of Augmentation,
