Becauſe if we reaſſume what hath been above demonſtrated,
Priſms and Cylinders, and that on Baſes equall to thoſe of the
ſaid Cylinders, we make Cones of the ſame Matter, and
times as high as the Cylinders, they ſhall reſt afloat, for that in Maſs
and Gravity they ſhall be equall to thoſe Cylinders, and by having
their Baſes equall to thoſe of the Cylinders, they ſhall leave equall
Maſſes of Air included within the Ramparts. This, which for
ple ſake hath been demonſtrated, in Priſms, Cylinders, Cones and
Piramids, might be proved in all other Solid Figures, but it would
require a whole Volume (ſuch is the multitude and variety of their
Symptoms and Accidents) to comprehend the particuler demonſtration
of them all, and of their ſeverall Segments: but I will to avoid prolixity
in the preſent Diſcourſe, content my ſelf, that by what I have declared
every one of ordinary Capacity may comprehend, that there is not
any Matter ſo grave, no not Gold it ſelf, of which one may not form
all ſorts of Figures, which by vertue of the ſuperiour Air adherent to
them, and not by the Waters Reſiſtance of Penetration, do remain
afloat, ſo that they ſink not. Nay, farther, I will ſhew, for removing
