SALV. And was you ſo credulous, as to ſuffer your ſelf to be
perſwaded to believe theſe fopperies, ſo long as you had your
ſenſes about you to confute them, and to underſtand the
truth thereof? Therefore tell me, that great ſtone, and that
Canon bullet, which but onely laid upon a table, did continue
immoveable againſt the moſt impetuous winds, according as you a
little before did affirm, if it had been a ball of cork or other light
ſtuffe, think you that the wind would have removed it from its
place?

place?
SIMP. Yes, and I am aſſured that it would have blown it
quite away, and with ſo much more velocity, by how much the
matter was lighter, for upon this reaſon we ſee the clouds to be
tranſported with a velocity equal to that of the wind that drives
them.
quite away, and with ſo much more velocity, by how much the
matter was lighter, for upon this reaſon we ſee the clouds to be
tranſported with a velocity equal to that of the wind that drives
them.
SALV. And what is the Wind?
SIMP. The Wind is defined to be nothing elſe but air moved.
SALV. Then the moved air doth carry light things more
ſwiftly, and to a greater diſtance, then it doth heavy.

SIMP. Yes certainly.
SALV. But if you were to throw with your arm a ſtone, and a
lock of cotton wool, which would move ſwiſteſt and fartheſt?

SIMP. The ſtone by much; nay the wool would fall at my
feet.
feet.
SALV. But, if that which moveth the projected ſubſtance,
ter it is delivered from the hand, be no other than the air moved
by the arm, and the moved air do more eaſily bear away light
than grave matters, how cometh it that the project of wool flieth
not farther, and ſwifter than that of ſtone? Certainly it
eth that the ſtone hath ſome other impulſe beſides the motion of
the air. Furthermore, if two ſtrings of equal length did hang
at yonder beam, and at the end of one there was faſtened a
let of lead, and a ball of cotton wool at the other, and both
were carried to an equal diſtance from the perpendicular, and
then let go; it is not to be doubted, but that both the one and
the other would move towards the perpendicular, and that being
carried by their own impetus, they would go a certain ſpace
yond it, and afterwards return thither again. But which of theſe
two pendent Globes do you think, would continue longeſt in
tion, before that it would come to reſt in its perpendicularity?

and that of wool but two or three at the moſt.

SALV. So that that impetus and that mobility whatſoever is
the cauſe thereof, would conſerve its ſelf longer in grave
ſtances, than light; I proceed now to another particular, and
mand of you, why the air doth not carry away that Lemon
which is upon that ſame Table?
