Heavens be of one Thickneſs, and the Element
of Fire another, and the upper Region of Air
diſtinct from both theſe, and the Lower Re-
gion ſeveral from all the reſt, there would
then be ſuch a Multiplicity of Refractions, as
muſt neceſſarily deſtroy the Certainty of all
Aſtronomical Obſervations. All which In-
conveniences might be avoided, by ſuppoſing
(as we do) that there is only one Orb of Va-
porous Air which encompaſſes our Earth, all
the reſt being Æthereal, and of the ſame per-
ſpicuity.

The Scituation of this Element does no
112. way agree with Ariſtotle's own Principles ;
or that common Providence of Nature, which
we may diſcern in ordinary Matters. For if
the Heavens be without all Elementary Qua-
lities, as is uſually ſuppoſed, then it would be
a very incongruous thing for the Element of
Fire to be placed immediately next unto it:
Since the Heat of this is the moſt Powerful
and Vigorous Quality that is amongſt all the
reſt ; And Nature in her other Works, does
not join Extreams, but by ſomething of a mid-
dle Diſpoſition. So in every Frame of our
Bodies, the Bones which are of a hard Sub-
ſtance, and the Fleſh of a ſoft, are not joined
together but by the Interceſſion of Membranes
and Griſſels, ſuch as being of a middle Na-
ture may fitly come betwixt.

Place, and certain it is, that Nature does not
do any thing in Vain.
