And that long continuing rough after a ſtorm, dependeth on
the gravity of the water: For, as I have elſewhere ſaid, light
dies are much eaſier to be moved than the more grave, but yet
are ſo much the leſs apt to conſerve the motion imparted, when
once the moving cauſe ceaſeth. Whence it comes that the Aire,
as being of it ſelf very light and thin, is eaſily mov'd by any very
ſmall force, yet it is withall very unable to hold on its motion,
the Mover once ceaſing. Therefore, as to the Aire which
rons the Terreſtrial Globe, I would fay, that by reaſon of its
adherence, it is no leſſe carried about therewith then the Water;
and eſpecially that part which is contained in its veſſels; which
veſſels are the valleys encloſed with Mountains. And we may
with much more reaſon affirm that this ſame part of the Air is
carried round, and born forwards by the rugged parts of the
Earth, than that the higher is whirl'd about by the motion of the
Heavens, as ye Peripateticks maintain.

higheſt Mountains, is carried round by the uneven parts of the
Earths ſurface: from whence it ſhould ſeem, that it muſt of
ſequence come to paſſe, that in caſe the ſuperficies of the Earth

ſo much uniformity. Now the ſurface of this our Globe, is not
