And hence (by the way) we may derive
a new aſſiſtance to judge of that famous
Controverſie diſputed among Naturaliſts
and Phyſitians, ever ſince Galens time,
ſome maintaining that the Cheſt, with the
contained Lungs, may be reſembled to a
pair of Bellows, which comes therefore
to be fill'd becauſe it was dilated: And o
thers pleading to have the compariſon
made to a Bladder, which is therefore di
lated becauſe it is fill'd. For as to the
Thorax, it ſeems evident from what has
been lately ſaid, that it, like a pair of Bel
lows, happens to be partly fill'd with Air,
but becauſe it was dilated: But as for the
Lungs themſelves, who want Fibres to
diſtend them, they may fitly enough be
compar'd to a Bladder; ſince they are di

which ruſhes into them upon the dilatation
of the Cheſt, in whoſe increaſed Cavity
it findes (as we freſhly noted) leſs reſiſt-
