tables; and not only in
the Solutions of _Amber_, _Benzoin_, and divers other Concretes made with
the same _Menstruum_, but also in divers Mineral Tinctures. And, not to
urge that familiar Instance of the Ruby of Sulphur, as _Chymists_ upon the
score of its Colour, call the Solution of Flowers of Brimstone, made with
the Spirit of Turpentine, nor to take notice of other more known Examples
of the aptness of Chymical Oyls, to produce a Red Colour with the Sulphur
they extract, or dissolve; not to insist (I say) upon Instances of this
nature, I shall further represent to you, as a thing remarkable, that, both
Acid and Alcalizate Salts, though in most other cases of such contrary
Operations, in reference to Colours, will with many Bodies that abound with
Sulphureous, or with Oyly parts, produce a Red; as is manifest partly in
the more Vulgar Instances of the Tinctures, or Solutions of Sulphur made
with _Lixiviums_, either of Calcin'd Tartar or Pot-ashes, and other Obvious
examples, partly by this, that the true Glass of Antimony extracted with
some Acid Spirits, with or without Wine, will yield a Red Tincture, and
that I know an Acid Liquor, which in a moment will turn Oyl of Turpentine
into a deep Red. But among the many Instances I could give you of the easie
Production of Redness by the Operation of Saline Spirit, as well as of
Spirit of Wine; I remember two or three of those I have tried, which seem
remarkable enough to deserve to be mention'd to you apart.

_EXPERIMENT XXXII._

But before we set them down, it will not perhaps appear impertinent to
premise;

That there seems to be a manifest Disparity betwixt Red Liquors, so that
some of them may be said to have a Genuine Redness in comparison of others,
that have a Yellowish Redness: For if you take (for example) a good
Tincture of _Chochineel_, dilute it never so much with fair Water, you will
not (as far as I can judge by what I have tried) be able to make it a
Yellow Liquor. Insomuch that a Single drop of a rich Solution of
_Cochineel_ in Spirit of Urine, being Diluted with above an Ounce of fair
Water, exhibited no Yellowishness at all, but a fair (though somewhat
faint) Pinck or Carnation; and even when _Cochineel_ was by degrees Diluted
much beyond the newly mention'd Colour, by the way formerly related to you
in the twenty fourth Experiment, I remember not, that there appear'd in the
whole Trial any Yellow. But if you take Balsom of Sulphur (for Instance)
