But this Last way of Explicating Blackness, I
shall content my Self to have Propos'd, without either Adopting it, or
absolutely Rejecting it. For the Hardness of Touchstones, Black Marble and
other Bodies, that being Black are Solid, seem to make it somewhat
Improbable, that such Bodies should be of so Yielding a Texture, unless we
should say, that some Bodies may be more Dispos'd to Yield to the Impulses
of the Corpuscles of Light by reason of a Peculiar Texture, than other
Bodies, that in other Tryals appear to be Softer than they. But though the
Former of these two Explications of Blackness be that, by which we shall
Endeavour to give an Account of it, yet as we said, we shall not Absolutely
Reject this Latter, partly because they both Agree in this, that Black
Bodies Reflect but Little of the Light that falls on them, and partly
because it is not Impossible, that in some Cases both the Disposition of
the Superficial particles, as to Figure and Position, and the Yielding of
the Body, or some of its Parts, may joyntly, though not in an Equal measure
concurr to the rendring of a Body Black. The Considerations that induc'd me
to propose this Notion of Blackness, as I Explan'd it, are principally
these:
