Though I will
not undertake, that those Colours in that Substance shall not be much more
Orient, than Lasting; and though (_Pyrophilus_) this Experiment may seem to
be almost the same with those already deliver'd concerning Syrrup of
Violets, and the Juice of Blew-bottles, yet I think it not amiss to take
this Occasion to inform you, that this Experiment reaches much farther,
than perhaps you yet imagine, and may be of good Use to those, whom it
concerns to know, how Dying Stuffs may be wrought upon by Saline Liquors.
For, I have found this Experiment to succeed in so many Various Berries,
Flowers, Blossoms, and other finer Parts of Vegetables, that neither my
Memory, nor my Leisure serves me to enumerate them. And it is somewhat
surprizing to see, by how Differingly-colour'd Flowers, or Blossoms, (for
example) the Paper being stain'd, will by an Acid Spirit be immediately
turn'd Red, and by any _Alcaly_ or any Urinous Spirit turn'd Green;
insomuch that ev'n the crush'd Blossoms of _Meserion_, (which I gather'd in
Winter and frosty Weather) and those of Pease, crush'd upon White Paper,
how remote soever their Colours be from Green, would in a moment pass into
a deep Degree of that Colour, upon the Touch of an Alcalizate Liquor.
