OEchis kind is an Experiment lately related to me by
MIP. Flalley, erho, in dirins decp into the Sea, Found
in a clear Sun Phine day, that irtien he ras Cunk many
Lathoms deep into che Water, theupper part oF his
Hland in irtrich the Sun one directis through the
Nater looked oF a red Colour, and the under part ot
his Lland illuminated by Lisht reflected trom the Water
belor looked oreen. For thence it may be sathered,
that the Sea- rater reflects back the violet and blue
makcins rars most catilr, and lets thered makins rays
Palo most ticely and copioully to creat depths. FOr
chereby thesuns direct Lisht at all sreat depths, by
realon ot the predominatins red makins rays, mult
appeur red; and the greater the depth is, the Fuller
and intenter mustthat red be. And at such dexths a5
the violet makins rays scarce Denetrate unto, the blue-
makins, srcen makcins and vellormakins rayS beIM
reslected trom beloir more copiously chan thered makIM
Ones, must compound a sreen.
Nou it chere be tiro Liquors of Fui Colours, sup-
Pole a red and a bluc, and Both oE them (0 thick a5
lustices to make their COlours sufficiently FuIl; though
cither Liquor De Cutticienely transparent apart, Vet
vill vou not be able to see through both together. LOr
it ouly thered makins cays pals through one Liquor,
and onlr the blue makcins chroush the other, no rayS
can pass chroush both. This MP. Hoote tried calually
rith Glals redges filled rith red and blue Liguors,
and ras surprized at the unexpected erent, the realon
oFit beine then untnomn; irhich mates me trust the
more to his Lxperiment, thoush lhare not eryed it
My PeIE. But he that rould repeat it, must take care
the Liquors be ol very 800d and FuII COlOurS.
