or the most part red:

And secondly, That it is not meerly the colour of the Air interpos'd, will,
I suppose, without much more difficulty be yielded, seeing that we may
observe a very great _interstitium_ of Air betwixt the Object, and the Eye,
makes it appear of a dead blew, far enough differing from a red, or yellow.

But thirdly, That it proceeds from the refraction, or inflection, of the
rays by the _Atmosphere_, this following Experiment will, I suppose,
sufficiently manifest.

Take a sphaerical Crystalline Viol, such as is describ'd in the fifth
Figure ABCD, and, having fill'd it with pure clear Water, expose it to the
Sun beams; then taking a piece of very fine _Venice_ Paper, apply it
against that side of the Globe that is opposite to the Sun, as against the
side BC, and you shall perceive a bright red Ring to appear, caus'd by the
refraction of the Rays, AAAA, which is made by the Globe; in which
Experiment, if the Glass and Water be very cleer, so that there be no Sands
nor bubbles in the Glass, nor dirt in the Water, you shall not perceive any
appearance of any other colour. To apply which Experiment, we may imagine
the _Atmosphere_ to be a great transparent Globe, which being of a
substance more dense then the other, or (which comes to the same) that has
its parts more dense towards the middle, the Sun beams that are tangents,
or next within the tangents of this Globe, will be refracted or inflected
from their direct passage towards the center of the Globe, whence,
according to the laws of refractions made in a triangular _Prism_, and the
generation of colour set down in the description of Muscovi-glass there
must necessarily appear a red colour in the _transitus_ or passage of those
tangent Rays. To make this more plain, we will suppose (in the sixth
_Figure_) ABCD, to represent the Globe of the _Atmosphere_, EFGH to
represent the opacous Globe of the Earth, lying in the midst of it, neer to
which, the parts of the Air, sustaining a very great pressure, are thereby
very much condens'd, from whence those Rays that are by inflection made
tangents to the Globe of the Earth, and those without them, that pass
through the more condens'd part of the _Atmosphere_, as suppose between A
and E, are by reason of the inequality of the _medium_, inflected towards
the center, whereby there must necessarily be generated a red colour, as is
more plainly shewn in the former cited place; hence whatsoever opacous
bodies (as
