<s>SALV. </s><s>And was you &longs;o credulous, as to &longs;uffer your &longs;elf to be <lb/>

&longs;en&longs;es about you to confute them, and to under&longs;tand the <lb/>

Canon bullet, which but onely laid upon a table, did continue <lb/>
immoveable again&longs;t the mo&longs;t impetuous winds, according as you a <lb/>
little before did affirm, if it had been a ball of cork or other light <lb/>
&longs;tuffe, think you that the wind would have removed it from its <lb/>
place?</s>

<s>SIMP. Yes, and I am a&longs;&longs;ured that it would have blown it <lb/>
quite away, and with &longs;o much more velocity, by how much the <lb/>
matter was lighter, for upon this rea&longs;on we &longs;ee the clouds to be <lb/>
tran&longs;ported with a velocity equal to that of the wind that drives <lb/>
them.</s>

<s>SALV. </s><s>And what is the Wind?</s>

<s>SIMP. </s><s>The Wind is defined to be nothing el&longs;e but air moved.</s>

<s>SALV. </s><s>Then the moved air doth carry light things more <lb/>
&longs;wiftly, and to a greater di&longs;tance, then it doth heavy.</s>

<s>SIMP. </s><s>Yes certainly.</s>

<s>SALV. </s><s>But if you were to throw with your arm a &longs;tone, and a <lb/>
lock of cotton wool, which would move &longs;wi&longs;te&longs;t and farthe&longs;t?</s>

<s>SIMP. </s><s>The &longs;tone by much; nay the wool would fall at my <lb/>
feet.</s>

<s>SALV. But, if that which moveth the projected &longs;ub&longs;tance, af <lb/>
ter it is delivered from the hand, be no other than the air moved <lb/>
by the arm, and the moved air do more ea&longs;ily bear away light <lb/>
than grave matters, how cometh it that the project of wool flieth <lb/>
not farther, and &longs;wifter than that of &longs;tone? </s><s>Certainly it argu <lb/>
eth that the &longs;tone hath &longs;ome other impul&longs;e be&longs;ides the motion of <lb/>
the air. </s><s>Furthermore, if two &longs;trings of equal length did hang <lb/>
at yonder beam, and at the end of one there was fa&longs;tened a bul <lb/>
let of lead, and a ball of cotton wool at the other, and both <lb/>
were carried to an equal di&longs;tance from the perpendicular, and <lb/>
then let go; it is not to be doubted, but that both the one and <lb/>
the other would move towards the perpendicular, and that being <lb/>
carried by their own <emph type="italics"/>impetus,<emph.end type="italics"/> they would go a certain &longs;pace be <lb/>
yond it, and afterwards return thither again. </s><s>But which of the&longs;e <lb/>
two pendent Globes do you think, would continue longe&longs;t in mo <lb/>
tion, before that it would come to re&longs;t in its perpendicularity?</s>

<s>SIMP. </s><s>The ball of lead would &longs;wing to and again many times, <lb/>
and that of wool but two or three at the mo&longs;t.</s>

the cau&longs;e thereof, would con&longs;erve its &longs;elf longer in grave &longs;ub <lb/>
&longs;tances, than light; I proceed now to another particular, and de <lb/>
mand of you, why the air doth not carry away that Lemon <lb/>
