Aectedthan the other Coloursred and riolet, and (o ofthe
rest. But tomake these Fxperimentsthe more manifest,
luch Bodies ouoht to be chosen as trave the Fullest and
most virid Colours, and tro ot thole Bodies are to DC
compared together. Thus, tor instance, it Cinnaber
and ultra marine blue, or Pome other FuII blue be
held together in the homoseneal Lighe, ther rill both
appear red, but the Cinnaber ill appear oF a Aronsl)
luminous and resplendent red, and the ultra marine
blue oF a Faint oblcure and dark red; and it ther be
held togecher in the blue homogeneal Light they will
both appear blue, but the ultra maxine will appear o
a Aronsly luminous and resplendent bluc, and the
Cinmaber oF a Faine and dark blue. Which puts it out
ot dispute, that the Cinnaber restects the red Light
muchinore copiously than the ultra marine doth, and
the ultra marine retlects the blue Lioht much more co
piousr chan the Cinnaber doth. The lame Fxperiment
nar De tryed succestuily rith red Lead and Indico, ot
Writh any other trro coloured Bodies, iF due allorvance
be made for che ditferent Arensth or Wreaknels oF theis
Colour and LioHt.
And a5 therealon oF the Colours ot natural Bodies is
erident by chese Fxperimenes, lo it is Further contirmed
and put past dispute by the turo trst Lxperiments ofthe
tirs BO0k, Wrhereby trras proved in tuch Bodies that
the rellected Lighe Which ditter in Colours do dister also
in degrees ot retransibilier. For chence itS CerFaim,
that lome Bodies retleet the more retransible, othere
the lels retransible rassmore copiousty.
