Nor
shall I now stay to Enquire, whether some of those other ways, (as a
Disposition to Alter the Velocity, the Rotation, or the Order and Manner of
Appulse so the Eye of the Reflected Corpuscles that Compos'd the Incident
Beams of Light) which we mention'd when we consider'd the Production of
Colours in General, may not in some Cases be Applicable to those of White
and Black Bodies: For I am yet so much a _Seeker_ in this Matter, and so
little Wedded to the Opinions I have propos'd, that what I am to add shall
be but the Beginning of a Collection of Experiments and Observation towards
the History of Whiteness and Blackness, without at present interposing my
Explications of them, that so, I may assist your Enquires without much
Fore-stalling or Biassing your Judgment.

EXPERIMENT I.
Having promis'd in the 114, and 115. Pages of the foregoing Discourse of
Whiteness and Blackness, to shew, that those two Colours may by a change of
Texture in bodies, each of them apart Diaphanous and Colourless, be at
pleasure and in a trice as well Generated as Destroy'd, We shall begin with
Experiments that may acquit us of that promise.
