But not finding at present in my Collections
about Colours any thing set down of this Kind, I shall, till I have
opportunity to repeat them, content my self to add what I find Register'd
concerning Colours look'd on by Candle-light, in regard that not only the
Experiment is more easie to be repeated, but the Objects being the Same
Sorts of Colour'd Paper lastly mention'd, the Collation of the two
Experiments may help to make the Conjectures they will suggest somewhat the
less uncertain.
Within a few dayes of the time above mention'd, divers Sheets of Colour'd
Paper that had been look'd upon before in the Sunshine were look'd upon at
night by the light of a pretty big Candle, (snuff'd) and the Changes that
were observ'd were these.
The Yellow seem'd much fainter than in the Day, and inclinable to a pale
Straw Colour.
The Red seem'd little Chang'd; but seem'd to Reflect Light more strongly
than any other Colour (for White was none of them.)
A fair Deep Green look'd upon by it self seem'd to be a Dark Blew: But
being look'd upon together with a Dark Blew, appear'd Greenish; and beheld
together with a Yellow appear'd more Blew than at first.
The Blew look'd more like a Deep Purple or Murray than it had done in the
Daylight.
