sth Obserrations compared with the fourtti and
ciotth.
By the precedent Obserrations it appears also, thaF
Whiteness is a dissimilar mixture oF aIl Colours, and that
Light is a mixture oF rars indued rith all thole CO-
tOurS. For considerins the multitude oF the, RingS OF
ColOurS, in thc 2d, 12th and 24th Oblerrations, it is
manifest that althouoh in the ath and L8th ObCCeVA-
tions there appear no more than eiont or nine ot thole
RingS, Vet there are really a Far greater number, wrhich
lo muctr intertere aud mingle ith one anothiei, a5 alter
those eiont or nine revolutions to dilute one another
Wholly, and constitute an even and sensibly unitorm
Wrtitenels. And consequentr that irhitenels nust DC
alloved a mixture ot all Colours, and the Lishe whieh
Conrers it to the fiye must bea mixture oF rars indued

But Further, by the 24th Oblerration, IE apPCaIS,
that there is a constant relation between Cotours and
Retransibilier, the most retransible rars beins violet,
the least retransible red, and thole ot intermediate C0.
lourstravins proportionably intermediate degrees ot re-
Frangibilier. And by the 13th, 2gth and 1gth Ob(er-
vations, compared with the Athos IBth, There apPCaIS
to be the lame constant relation betrreen Colour and
Reslexibility, the riolet beino in like circumstances re-
Aected at least thicknesses ot any thin Plate or Bubble,
the red at sreatest thicknesses, and the intermediate
Colours at intermediate thickneRes. Whence it FOl-
lons, that the coloritique dispositions ot rars are al(0
connate riththem and immutable, and by consequence
