Tuccessirely the Teeth of this Instrument near the L enS,
l’intercepted part of the Colours by the interpoled
Looth, WrhilCt the rest otthem ent on throughthe in-
terral oF the Teeth tothe Paper DF, and there pain-
ted a round Colar Image. Bucthe Paper I had Arst Pla-
ced lo, thac the Image misht appear white a5 otten
a5the Comb as taken avay; and then the Comb bC-
ins as as Caid interpoled, that wrhiteness by realon ot
che intercepted part oF the COlours at the Lens did al-
rars chanse into the Colour compounded ot thole
Colours Wrhich irere not intercepted, and that Colour
ras by the motion ofthe Comb perpetually varied l0
that in the passins ot every Tooth over the Lens aII
thele Colours red, vellor, sreen, blue and purple, did
alrars succeed one another. I cauled theretore allthe
Leethto pass successirely over the Lens, and irhen the
motion ras Por, there appeared a perpetual succession
ot the Colours upon the P’aper: But it Llo much acce-
lerated the motion, thatthe Colours by reason of their
quick succession couid not be distinguithred From one
another, the appearance of the linsle Colours cealed..
Phere rras no red, no vello, no sreen, nO bluC, nOL
Durple to be scen ans longer, buc trom a contulion ot
ehem all there arose one unitorm white C olour. OF he
Light whrich nou by the mixture ot all the Colours ap-
peared white, there ras no part really irhite. One
part Was red, another vellor, a third green, a Fourth
blue, a tilth purple, and every part retains itS PrODeF
Colour till it srikre thesenlorium. IF the impreltions
