Lens, theblue ac eWrill accordinsly disappear and re
turn, wichout ans change made in the red at P. ThC
red cheretore depends on one lort ot rays, and the blue
on ariother Fort, Wrhich in the Focus Ci ertrere they are
commixt do not aet on one another. And there is th.
Pame realon of the other Colours.
lconsidered Further, that wrhen the most retrangible
rays PP, and che least retransible ones IF, are by con
vergins inclined toone another, the Paper, it held very
oblique tothose rays in the Locus C, mioht reRect one
Tort ot them more copioustr than the other COrt, and D)
that means the refected Light rould be tinged in that
Focus rith the Colour ot the predominant FayS, prO
vided those rars sererally retained their C OlOurS OF CO
loritc qualities in the composition ot wrhice made by
them in that Focus. But il they did noc retain them
in that White, but became all ot them Ceverally endued
there ith a disposition to Prike the sense with the per-
ception oF wrhite, then ther could nerer lose their irhite
nels by such reflexions. Linclined theretore the l’aper
tothe rays very obliquelr, as in the second Experiment
ofthis Book, that the most retrangible rays might De
more copioully reflected than the rest, and the wrhite
Dels at lensth changed successirelr into blue, indico
and violet. Then linclined it the contrary wrar, tha
themost retransible rars mistit Demore copious in the
retlected Light than the rest, and the erhiteness turnec
Succellively to rellorr, oranse and red.
