e and the same Black Mineral, Antimony, may be made to afford
_Flowers_, some of them Red, and some Grey, and, which is more strange,
some of them purely White. And 'tis the Prescription of some Glass-men by
exquisitely mingling a convenient proportion of Brimstone, Sal-Armoniack,
and Quicksilver, and Subliming them, together, to make a Sublimate of an
excellent Blew; and though having caus'd the Experiment to be made, we
found the produc'd Sublimate to be far from being of a lovely Colour, (as
was promis'd) that there and there, it seem'd Blewish, and at least was of
a Colour differing enough from either of the Ingredients, which is
sufficient for our present purpose. But a much finer Colour is promis'd by
some of the Empiricks, that pretend to Secrets, who tell us, that Orpiment,
being Sublim'd, will afford among the Parts of it that fly Upward, some
little Masses, which, though the Mineral it self be of a good Yellow, will
be Red enough to emulate Rubies, both in Colour and Translucency. And this
Experiment may, for ought I know, sometimes succeed; for I remember, that
having in a small Bolt-head purposely sublim'd some powder'd Orpiment, we
could in the Lower part of the Sublimate discern here and there some
Reddish Lines, though much of the Upper part of the Sublimate consisted of
a matter, which was not alone purely Yellow, but transparent almost like a
Powder. And we have also this way obtain'd a Sublimate, the Lower part
whereof though it consisted not of Rubies, yet the small pieces of it,
which were Numerous enough, were of a pleasant Reddish Colour, and
Glitter'd very prettily. But to insist on such kind of Trials and
Observations (where the ascending Fumes of Bodies differ in Colour from the
Bodies themselves) though it might indeed Inrich the History of Colours,
would Robb me of too much of the little time I have to dispatch what I have
further to tell you concerning them.

_EXPERIMENT XXXIX_

Take the dry'd Buds (or Blossoms) of the Pomegranate Tree, (which are
commonly call'd in the Shops _Balaustiums_) pull off the Reddish Leaves,
and by a gentle Ebullition of them in fair Water, or by a competent
Infusion of them in like Water well heated, extract a faint Reddish
Tincture, which if the Liquor be turbid, you may Clarifie it by Filtrating
it Into this, if you pour a little good Spirit of Urine, or some other
Spirit abounding in the like sort of Volatile Salts, the Mixture will
presently turn of a dark Gre
