And as for the eaſie yielding of the Air
to the Bodies that move in it, if we con
ſider that the Corpuſcles whereof it con
ſiſts, though of a ſpringy nature, are yet
ſo very ſmall, as to make up (which 'tis
manifeſt they doe) a fluid Body, it will
not be difficult to conceive, that in the
Air, as in other Bodies that are fluid, the
little Bodies it conſiſts of are in an almoſt
reſtleſs motion, whereby they become
(as we have more fully diſcourſed in ano
ther Treatiſe) very much diſpoſed to
yield to other Bodies, or eaſie to be diſ
plac'd by them, and that the ſame Cor

they are intire Corpuſcles, that if ſome
