to ſome ſo true and manifeſt in the preſent Contemplation; nay,

rather it ſeems, that in this caſe the Force is multiplied without the

Movers moving a longer way than the Moveable: In regard, that

if we ſhall in the Triangle A B C ſuppoſe the Line A B to be the

Plane of the Horizon, A C the elevated Plane, whoſe Altitude is

meaſured by the Perpendicular C B, a Moveable placed upon the

Plane A C, and the Cord E D F tyed to it, and a Force or Weight

applyed in F that hath to the

Gravity of the Weight E the

ſame proportion that the Line

B C hath to C A; by what

hath been demonſtrated, the

Weight F ſhall deſcend

downwards, drawing the

Moveable E along the eleva

ted Plane; nor ſhall the Move

able E meaſure a greater Space

when it ſhall have paſſed the

whole Line A C, than that which the ſaid Grave F meaſureth in its

deſcent downwards. But here yet it muſt be advertiſed, that al

though the Moveable E ſhall have paſſed the whole Line A C, in

the ſame Time that the other Grave F ſhall have been abaſed the

like Space, nevertheleſs the Grave E ſhall not have retired from the

common Center of things Grave more than the Space of the Per

pendicular C B. but yet the Grave F deſcending Perpendicularly ſhall

be abaſed a Space equal to the whole Line A C. And becauſe Grave

Bodies make no Reſiſtance to Tranſverſal Motions, but only ſo

far as they happen to recede from the Center of the Earth; There

fore the Moveable E in all the Motion A C being raiſed no more

than the length of the Line CB, but the other F being abaſed per

pendicularly the quantity of all the Line A C: Therefore we may

deſervedly affirm that Way of the Force E maintaineth the ſame

proportion to the Force F that the Line A C hath to C B; that is,

the Weight E to the Weight F. It very much importeth, therefore,

to conſider by [or along] what Lines the Motions are made, eſpe

cially in exanimate Grave Bodies, the Moments of which have their

total Vigour, and entire Reſiſtance in the Line Perpendicular to

the Horizon; and in the others tranſverſally Elevated and Inclined

they feel the more or leſs Vigour, Impetus, or Reſiſtance, the more

or leſs thoſe Inclinations approach unto the Perpendicular Inclina

tion.
