will, I presume, suffice to manifest the main thing for
which I now allege them; I find then Among my _Adversaria_, the following
Narrative.

_October_ the 11. About ten in the Morning in Sun-shiny Weather, (but not
without fleeting Clouds) we took several sorts of Paper Stain'd, some of
one Colour, and some of another; and in a Darken'd Room whose Window look'd
Southward, we cast the Beams that came in at a hole about three Inches and
a half in Diameter, upon a White wall that was plac'd on one side, about
five foot distance from them.

The White gave much the Brightest Reflection.

The Green, Red, and Blew being Compar'd together, the Red gave much the
strongest Reflection, and manifestly enough also threw its _Colour_ upon
the Wall; The Green and Blew were scarce Discernable by their Colours, and
seem'd to reflect an almost Equal Light.

The Yellow Compar'd with the two last nam'd, Reflected somewhat more Light.

The Red and Purple being Compar'd together, the former manifestly Reflected
a good deal more Light.

The Blew and Purple Compar'd together, the former seem'd to Reflect a
little more Light, though the Purple Colour were more manifestly seen.

A Sheet of very well fleck'd Marbl'd Paper being Apply'd as the others, did
not cast any or its Distinct Colours upon the Wall; nor throw its Light
upon it with an Equal Diffusion, but threw the Beams Unstain'd and Bright
to this and that part of the Wall, as if it's Polish had given it the
Nature of a specular Body. But comparing it with a sheet of White Paper, we
found the Reflection of the latter to be much Stronger, it diffusing almost
as much Light to a _good Extent_ as the Marble Paper did to _one part_ of
the Wall.

The Green and Purple left us somewhat in suspence which Reflected the most
Light; only the Purple seem'd to have some little Advantage over the Green,
which was Dark in its kind.

Thus much I find in our above mention'd _Collections_, among which there
are also some Notes concerning the Production of _Compounded Colours_, _by
Reflection_ from Bodyes differingly Colour'd. And these Notes we intended
should supply us with what we should mention as our second Experiment: but
having lost the Paper that contain'd the Particulars, and remembring onely
in General, that if the Objects which Reflected the Light were not Strongly
Colour'd and somewhat Glossy, the Reflected Beams would not manifestly make
a Compounded Colour upon the Wall, and even then
