on, and that it is not poſſible to find any Solid Body, be it of what
Figure it will, which being put into the Water, its Motion upwards
or downwards, according as it exceedeth, or ſhall be exceeded by
the Water in Gravity (although ſuch exceſſe and difference be
ſenſible) ſhall be prohibited, and taken away, by the Craſſitude of
the ſaid Water. When, therefore, we ſee the Board of Ebony, or
of other Matter, more grave than the Water, to ſtay in the
fines of the Water and Air, without ſubmerging, we muſt have

Effect, than to the breadth of the Figure, unable to overcome
Renitence with which the Water oppoſeth Diviſion, ſince there is
no Reſiſtance; and from that which is not in being, we can
no Action. It remains moſt true, therefore, as we have ſaid before,
this ſo ſucceds, for that that which in ſuch manner put upon the

this which is put into the Water, is the pure Board of Ebony, which
for that it is more grave than the Water, ſinketh, and that which is
put upon the Water, is a Compoſition of Ebony, and of ſo much
Air, that both together are ſpecifically leſs grave than the
