1Riviolo makes it probable, that the At
moſphere may, at leaſt in divers places, be
at leaſt 50 miles high. So that according to
a moderate eſtimate of the thickneſs of
the Atmoſphere, we may well ſuppoſe,
that a Column of Air, of many miles in
height, leaning upon ſome ſpringy Cor
puſcles of Air here below, may have
weight enough to bend their little ſprings,
and keep them bent: As, to reſume our
former compariſon, if there were fleeces of
Wooll pil'd up to a mountainous height
upon one another, the Hairs that com
poſe the lowermoſt locks which ſupport
the reſt, would, by the weight of all the
Wool above them, be as well ſtrongly
compreſſed, as if a man ſhould ſqueeze
them together in his hands, or imploy any
ſuch other moderate force to compreſs
them. So that we need not wonder, that
upon the taking off the incumbent Air
from any parcel of the Atmoſphere here
below, the Corpuſcles, whereof that un
dermoſt Air conſiſts, ſhould diſplay them
ſelves, and take up more room then be
fore.
