all the Colours in due
order, the violet lying on the inside of the Fringe next the Shadow, the
red on the outside farthest from the Shadow, and the blue, green, and
yellow, in the middle. And, in like manner, the middlemost Fringes of
all the Colours lying in order, and being contiguous, make another broad
Fringe composed of all the Colours; and the outmost Fringes of all the
Colours lying in order, and being contiguous, make a third broad Fringe
composed of all the Colours. These are the three Fringes of colour'd
Light with which the Shadows of all Bodies are border'd in the second
Observation.

When I made the foregoing Observations, I design'd to repeat most of
them with more care and exactness, and to make some new ones for
determining the manner how the Rays of Light are bent in their passage
by Bodies, for making the Fringes of Colours with the dark lines between
them. But I was then interrupted, and cannot now think of taking these
things into farther Consideration. And since I have not finish'd this
part of my Design, I shall conclude with proposing only some Queries, in
order to a farther search to be made by others.

_Query_ 1. Do not Bodies act upon Light at a distance, and by their
action bend its Rays; and is not this action (_caeteris paribus_)
strongest at the least distance?

_Qu._ 2. Do not the Rays which differ in Refrangibility differ also in
Flexibity; and are they not by their different Inflexions separated from
one another, so as after separation to make the Colours in the three
Fringes above described? And after what manner are they inflected to
make those Fringes?

_Qu._ 3. Are not the Rays of Light in passing by the edges and sides of
Bodies, bent several times backwards and forwards, with a motion like
that of an Eel? And do not the three Fringes of colour'd Light
above-mention'd arise from three such bendings?

_Qu._ 4. Do not the Rays of Light which fall upon Bodies, and are
reflected or refracted, begin to bend before they arrive at the Bodies;
and are they not reflected, refracted, and inflected, by one and the
same Principle, acting variously in various Circumstances?

_Qu._ 5. Do not Bodies and Light act mutually upon one another; that is
to say, Bodies upon Light in emitting, reflecting, refracting and
inflecting it, and Light upon Bodies for heating them, and putting their
parts into a vibrating motion wherein heat consists?

_Qu._ 6. Do not black Bodies conceive heat more easi
