throush that space Mall be in a subduplicate proportion
ot the Forces, a5 Mathematicians rill casily understand.
And cheretore if the space ot actirity ot the retractins
superticies oE the Body bc considered a5 Tuch a space,
the motion ofthe ray generated by the retractins Force
ot the Body, during its paltase chroush that space
that is the motion BR must bc in a subduplicate
proportion ofthat retracting force: I Cay theretore that
thie square oF the Line BR, and by consequence the
refractins Force of the Body is verr nearly as the den-
sey ofthe Came Bodr. For this will axpear by the Fol.
lorrins Pable, Wrherein the proportion ot thesinesirhich
meature the retraxions of several Bodies, the square
OF BR suppotins C. B an unite, the densities of thc
Bodies ettimated by their specitick gravities, and theie
retractire porrer in respeet ol cheir densities are set
domn in sereral Columns.
