that I fear I &longs;hall have but a &longs;mall part of it left free and di&longs;in&shy; <lb/>
gaged, to apply to the principal matter that is treated of, and <lb/>
which of it &longs;elf is but even too ob&longs;cure and intricate: So that <lb/>
I intreat you to vouch&longs;afe me, having once di&longs;patcht the bu&longs;ine&longs;s <lb/>
of the ebbings and flowings, to do this honour to my hou&longs;e (and <lb/>
yours) &longs;ome other dayes, and to di&longs;cour&longs;e upon the &longs;o many other <lb/>
Problems that we have left in &longs;u&longs;pence; and which perhaps are <lb/>
no le&longs;s curious and admirable, than this that hath been di&longs;cu&longs;&longs;ed <lb/>
the&longs;e dayes pa&longs;t, and that now ought to draw to a con&shy; <lb/>

<p type="main"><s>SALV. </s><s>I &longs;hall be ready to &longs;erve you, but we mu&longs;t make more <lb/>
than one or two Se&longs;&longs;ions; if be&longs;ides the other que&longs;tions re&longs;erved <lb/>
to be handled apart, we would di&longs;cu&longs;&longs;e tho&longs;e many that pertain <lb/>
to the local motion, as well of natural moveables, as of the reject&shy; <lb/>

mick.<emph.end type="italics"/> But turning to our fir&longs;t purpo&longs;e, where we were about to <lb/>
declare, That the bodies moving circularly by a movent virtue, <lb/>
which continually remaineth the &longs;ame, the times of the circula&shy; <lb/>
tions were prefixt and determined, and impo&longs;&longs;ible to be made <lb/>
longer or &longs;horter, having given examples, and produced experi&shy; <lb/>
ments thereof, &longs;en&longs;ible, and fea&longs;ible, we may confirm the &longs;ame <lb/>
truth by the experiences of the Cele&longs;tial motions of the Planets; <lb/>
in which we &longs;ee the &longs;ame rule ob&longs;erved; for tho&longs;e that move by <lb/>
greater Circles, confirm longer times in pa&longs;&longs;ing them. </s><s>A mo&longs;t <lb/>
pertinent ob&longs;ervation of this we have from the <emph type="italics"/>Medic&aelig;an<emph.end type="italics"/> Pla&shy; <lb/>
nets, which in &longs;hort times make their revolutions about <emph type="italics"/>Jupiter<emph.end type="italics"/>: <lb/>
In&longs;omuch that it is not to be que&longs;tioned, nay we may hold it for <lb/>
&longs;ure and certain, that if for example, the Moon continuing to be <lb/>
moved by the &longs;ame movent faculty, &longs;hould retire by little and <lb/>
little in le&longs;&longs;er Circles, it would acquire a power of abreviating <lb/>
the times of its Periods, according to that <emph type="italics"/>Pendulum,<emph.end type="italics"/> of which in <lb/>
the cour&longs;e of its vibrations, we by degrees &longs;hortned the cord, that <lb/>
is contracted the Semidiameter of the circumferences by it pa&longs;&longs;ed. <lb/>

Moon, is &longs;een and verified e&longs;&longs;entially in fact. </s><s>Let us call to mind, <lb/>
that it hath been already concluded by us, together with <emph type="italics"/>Coperni-<emph.end type="italics"/> <lb/>

<emph type="italics"/>cus,<emph.end type="italics"/> That it is not po&longs;&longs;ible to &longs;eparate the Moon from the Earth, <lb/>
about which it without di&longs;pute revolveth in a Moneth: Let us <lb/>
remember al&longs;o that the Terre&longs;trial Globe, accompanyed alwayes <lb/>
by the Moon, goeth along the circumference of the Grand Orb <lb/>
about the Sun in a year, in which time the Moon revolveth about <lb/>
the Earth almo&longs;t thirteen times; from which revolution it follow&shy; <lb/>
