ly, unleſſe the other Weight B do move to E ſwiftly, it will not

be ſtrange, or inconſiſtent with the Order of Nature, that the

Velocity of the Motion of the Grave B, do compenſate the greater

Reſiſtance of the Weight A, ſo long as it moveth ſlowly to D,

and the other deſcendeth ſwiftly to E, and ſo on the contrary,

the Weight A being placed in the point D, and the other B in

the point E, it will not be unreaſonable that that falling leaſurely

to A, ſhould be able to raiſe the other haſtily to B, recovering by

its Gravity what it had loſt by it's Tardity of Motion. And by

this Diſcourſe we may come to know how the Velocity of the

Motion is able to encreaſe Moment in the Moveable, according to

that ſame proportion by which the ſaid Velocity of the Motion is

augmented.

There is alſo another thing, before we proceed any farther, to

be confidered; and this is touching the Diſtances, whereat, or

wherein Weights do hang: for it much imports how we are to

underſtand Diſtances equall, and unequall; and, in ſum, in what

manner they ought to be mea

ſured: for that A B being the

Right Line, and two equall

Weights being ſuſpended at

the very ends thereof, the point

C being taken in the midſt of

the ſaid Line, there ſhall be an

Equilibrium upon the ſame:

And the reaſon is for that the

Diſtance C B is equal to C A.

But if elevating the Line C B, moving it about the point C, it

ſhall be transferred into CD, ſo that the Ballance ſtand according

to the two Lines A C, and C D, the two equall Weights hanging

at the Terms A and D, ſhall no longer weigh equally on that

point C, becauſe the diſtance of the Weight placed in D, is made

leſſe then it was when it hanged in B. For if we confider the Lines,

along [or by] which the ſaid Graves make their Impulſe, and

would deſcend, in caſe they were freely moved, there is no doubt

but that they would make or deſcribe the Lines A G, D F, B H:

Therefore the Weight hanging on the point D, maketh it's Moment

and Impetus according to the Line D F: but when it hanged in

B, it made Impetus in the Line B H: and becauſe the Line D F is

nearer to the Fulciment C, then is the Line B H Therefore we

are to underſtand that the Weights hanging on the points A and D,

are not equi-diſtant from the point C, as they be when they are

conſtituted according to their Right Line A C B: And laſtly,
