to be Known, before I should judge my Self to have fully Comprehended the
True and Whole Nature of Colours; and therefore, though by making the
Experiments and Reflections deliver'd in this Paper, I have endeavour'd
somewhat to Lessen my Ignorance in this Matter, and think it far more
Desireable to discover a Little, than to discover Nothing, yet I pretend
but to make it Probable by the Experiments I mention, that some Colours may
be Plausibly enough Explicated in the General by the Doctrine here
propos'd; For whensoever I would Descend to the Minute and Accurate
Explication of Particulars, I find my Self very Sensible of the great
Obscurity of things, without excepting those which we never see but when
they are Enlightned, and confess with _Scaliger_[5], _Latet natura hæc_,
(says he, Speaking of that of Colour) _& sicut aliarum rerum species in
profundissima caligine inscitiæ humanæ._
