&longs;ed, which is the conclu&longs;ion of that was in di&longs;pute; Therefore, <lb/>
I reply, that tho&longs;e who make the Earth moveable, an&longs;wer, that <lb/>
the piece, and the ball that is in it, partake of the &longs;ame motion <lb/>
with the Earth; nay that they have this together with her from <lb/>
nature; and that therefore the ball departs in no other manner <lb/>
from its quie&longs;cence, but conjoyned with its motion about the cen <lb/>
tre, the which by its projection upwards, is neither taken away, <lb/>
nor hindered; and in this manner following, the univer&longs;al motion <lb/>
of the Earth towards the Ea&longs;t, it alwayes keepeth perpendicular <lb/>
over the &longs;aid piece, as well in its ri&longs;e as in its return. </s><s>And the <lb/>

in that manner.</s>

<s>SAGR. </s><s>But if the piece were placed, not perpendicularly, but <lb/>
inclining towards &longs;ome place, what would the motion of the ball <lb/>
be? </s><s>Would it go haply, as in the other &longs;hot, by the perpendi <lb/>

would pur&longs;ue its motion by a right line which prolongeth the e <lb/>
