<lb/> and con&longs;equently is able to bring a continual impediment to the
<lb/> plummet C; and for a proof that this is &longs;o, if we do but ob&longs;erve
<lb/> the thread A C, we &longs;hall &longs;ee it di&longs;tended not directly, but in an
<lb/> arch; and if in&longs;tead of the thread we take a chain, we &longs;hall di&longs;­
<lb/> cern the effect more per&longs;ectly; and e&longs;pecially removing the gra­
<lb/> <arrow.to.target n="marg412"></arrow.to.target>
<lb/> vity C, to a con&longs;iderable di&longs;tance from the perpendicular A B, for
<lb/> that the chain being compo&longs;ed of many loo&longs;e particles, and each of
<lb/> them of &longs;ome weight, the arches A E C, and A F D, will appear
<lb/> notably incurvated. </s><s>By rea&longs;on therefore, that the parts of the
<lb/> chain, according as they are neerer to the point A, de&longs;ire to make
<lb/> their vibrations more frequent, they permit not the lower parts of
<lb/> the &longs;aid chain to &longs;wing &longs;o far as naturally they would: and by
<lb/> continual detracting from the vibrations of the plummet C, they
<lb/> finally make it cea&longs;e to move, although the impediment of the air
<lb/> might be removed.</s></p>
