colour indifferently w^th w^ch 'tis illustrated, but yet
most luminous in red; & so Bise appeareth indif-
ferently of any colour w^th w^ch 'tis illustrated, but
yet most luminous in blew. And therefore Minium
reflecteth rayes of any colour, but most copiously
those endowed w^th red; & consequently when illustra-
ted w^th day-light, that is w^th all sorts of rayes pro-
miscuously blended, those qualified w^th red shall a-
bound most in the reflected light, & by their
prevalence cause it to appear of that colour. And
for y^e same reason Bise reflecting blew most copiously,
shall appear blew by y^e excesse of those rayes in its
reflected light; & y^e like of other bodies. And that this
is y^e intire & adequate cause of their colours is mani-
fest, because they have noe power to change or alter
the colour of any sort of rays incident apart, but put
on all colours indifferently w^th w^ch they are enlightened.

These thinges being so, it can be no longer dis-
puted whither there be colours in y^e dark, nor whi-
ther these |y| be the qualityes of y^e objects wee see,
no nor perhaps whether light be a bodie. ffor
since colours are qualityes of light, having its
rayes for their entire & imediate subject, how
can wee think those rayes qualityes also, unlesse
one quality may be y^e subject of & sustain another,
w^ch in effect is to call it substance. Wee should not
know bodies for substances were it not for their sen-
sible qualityes, & the principall of them |ose| being now
found due to something else, wee have as good rea-
son to beleive that to be a substance also. Besides
who ever thought any quality to be a heterogeneous
agregate such as light is discovered to be. But
to say \determine/ more absolutely what light is, after what
manner refracted, & by what modes or actions it
produceth in o^r minds the Phantasms of colours, is not
so easie. [illeg] . And I shall not mingle conjectures
w^th certaintyes.

Reviewing what I have written, I see y^e discours
it selfe will lead to divers experiments sufficient
