<s>SAGR. </s><s>I am rather very much plea&longs;ed with it, for that I re <lb/>
member that when I &longs;tudied Logick, I could never comprehend that <lb/>
&longs;o much cry'd up and mo&longs;t potent demon&longs;tration of <emph type="italics"/>Ari&longs;totle.<emph.end type="italics"/></s>

<s>SALV. </s><s>Let us go on therefore; and let <emph type="italics"/>Simplicius,<emph.end type="italics"/> tell me <lb/>
what that motion is which the &longs;tone maketh that is held fa&longs;t in the <lb/>
&longs;lit of the &longs;ling, when the boy &longs;wings it about to throw it a great <lb/>
way?</s>

<s>SIMP. </s><s>The motion of the &longs;tone, &longs;o long as it is in the &longs;lit, is <lb/>
circular, that is, moveth by the arch of a circle, who&longs;e &longs;tedfa&longs;t <lb/>
centre is the knitting of the &longs;houlder, and its &longs;emi-diameter the arm <lb/>
and &longs;tick.</s>

<s>SALV. </s><s>And when the &longs;tone leaveth the &longs;ling, what is its mo <lb/>
tion? </s><s>Doth it continue to follow its former circle, or doth it go <lb/>
by another line?</s>

<s>SIMP. </s><s>It will continue no longer to &longs;wing round, for then it <lb/>
would not go farther from the arm of the projicient, whereas <lb/>
we &longs;ee it go a great way off.</s>

<s>SALV. </s><s>With what motion doth it move then?</s>

<s>SIMP. </s><s>Give me a little time to think thereof; For I have ne <lb/>
ver con&longs;idered it before.</s>

<s>SALV. </s><s>Hark hither, <emph type="italics"/>Sagredus<emph.end type="italics"/>; this is the <emph type="italics"/>Quoddam remini&longs;ci<emph.end type="italics"/> <lb/>
in a &longs;ubject well under&longs;tood. </s><s>You have pau&longs;ed a great while, <lb/>
<emph type="italics"/>Simplicius.<emph.end type="italics"/></s>

<s>SIMP. </s><s>As far as I can &longs;ee, the motion received in going out of <lb/>
the &longs;ling, can be no other than by a right line; nay, it mu&longs;t ne <lb/>
ce&longs;&longs;arily be &longs;o, if we &longs;peak of the pure adventitious <emph type="italics"/>impetus.<emph.end type="italics"/> I <lb/>
was a little puzled to &longs;ee it make an arch, but becau&longs;e that arch <lb/>
bended all the way upwards, and no other way, I conceive that <lb/>
<arrow.to.target n="marg364"></arrow.to.target> <lb/>
that incurvation cometh from the gravity of the &longs;tone, which na <lb/>
turally draweth it downwards. </s><s>The impre&longs;&longs;ed <emph type="italics"/>impetus,<emph.end type="italics"/> I &longs;ay, <lb/>
without re&longs;pecting the natural, is by a right line.</s>

<s>SALV. </s><s>But by what right line? </s><s>Becau&longs;e infinite, and towards <lb/>
every &longs;ide may be produced from the &longs;lit of the &longs;ling, and from the <lb/>
point of the &longs;tones &longs;eparation from the &longs;ling.</s>

<s>SIMP. </s><s>It moveth by that line which goeth directly from the <lb/>
motion which the &longs;tone made in the &longs;ling.</s>

<s>SALV. </s><s>The motion of the &longs;tone whil&longs;t it was in the &longs;lit, you <lb/>
have affirmed already to be circular; now circularity oppo&longs;eth <lb/>
directne&longs;s, there not being in the circular line any part that is di <lb/>
rect or &longs;treight.</s>

<s>SIMP I mean not that the projected motion is direct in re <lb/>
&longs;pect of the whole circle, but in reference to that ultimate point, <lb/>
where the circular motion determineth. </s><s>I know what I would
