and the rest of the Circles ci, dR el, fm respectirelr.
rich che Came Corrs oF Rays by irhich che several corre-
sponding Circles CT, DK, F L, FM ivere illuminated.
In cheFigure P P compoled ot che orcater Circles, chree
ot those Circles AG, BH, CJ, are (0 expanded into one
anocher, chac che chree (orts oF RayS by itrich chole Cir-
cles are illuminated, cogether wich ocher innumerable POreS
oF incermediare Rays, are mixed ac QR in che midale of
che CireleBFI. And che like mixture happens chrouoh-
out almost che ihole lenseh oF che Ligure PI. Buc in
che Figure pr compoled ot che lels Circles, che chrec lels
Circles ag, bh, ci, Which ansiver to chose chree greater, do
nOF extend into one anocher; nor are chere aur ntere
minsled (o much 25 any erro of che chree Pores oF RaYS
by irtich chose Circles are illuminated, and ihich in che
Figure P T are all oF chem incerminoled ac BFI.
No hochac Phall thus consider ic, ill casily understand
chac che mixture is diminithed in che Came Proportion
wich che Diameters oF che Circles. IF the Diamerers ot
che Circles whils cheir Cencers remain che lame, be made
chrec times lels chan betore, che mixcure will bc also chrec
cimes lels; il cen cimes lels, the mixture will be cen eimes
lels, and (o of ocher Proportions. Thacis, the mixture
OF che Rays in chegrearer Figure P I will be co cheir mix-
cure in che lels pt, 25 che Lacitude of the greater Figure is
co che Lacieude ot che lels. For che Lacicudes of these Fi-
oures are equal co che Diameters ot cheir Circles. And
hence ic easily follons, thac che mixture oF che Rays in che
retracted Spectrum pF is to che mixture ol che Rays in the
direet and immediare Liohe oF chesun, as che breadth oF
chac Spectrum is coche ditterence bermeen che lengeh and
breadch ot chelame Spectrum.
