<s>SIMPL. </s><s>Stay a little; for I ju&longs;t now remember, that I have <lb/>
read in a little modern tract, full of many novelties; “That this <lb/>
&longs;econdary light is not derived from the Stars, nor innate in the <lb/>
Moon, and lea&longs;t of all communicated by the Earth, but that it is <lb/>
<arrow.to.target n="marg195"></arrow.to.target> <lb/>
received from the &longs;ame illumination of the Sun, which, the &longs;ub <lb/>
&longs;tance of the Lunar Globe being &longs;omewhat tran&longs;parent, pene <lb/>
trateth thorow all its body; but more livelily illuminateth the <lb/>
&longs;uperficies of the Hemi&longs;phere expo&longs;ed to the rays of the Sun: <lb/>
and its pro&longs;undity imbuing, and (as I may &longs;ay) &longs;wallowing that <lb/>
light, after the manner of a cloud or chry&longs;tal, tran&longs;mits it, and <lb/>
renders it vi&longs;ibly lucid. </s><s>And this (if I remember aright) he <lb/>
proveth by Authority, Experience and Rea&longs;on; citing <emph type="italics"/>Cleomedes, <lb/>
Vitellion, Macrobius,<emph.end type="italics"/> and a certain other modern Author: and <lb/>
adding, That it is &longs;een by experience to &longs;hine mo&longs;t in the days <lb/>
neare&longs;t the Conjunction, that is, when it is horned, and is chiefly <lb/>
bright about its limb. </s><s>And he farther writes, That in the Solar <lb/>
Ecclip&longs;es, when it is under the <emph type="italics"/>Di&longs;cus<emph.end type="italics"/> of the Sun, it may be &longs;een <lb/>
tran&longs;lucid, and more e&longs;pecially towards its utmo&longs;t Circle. </s><s>And <lb/>
in the next place, for Arguments, as I think, he &longs;aith, That it not <lb/>
being able to derive that light either from the Earth, or from the <lb/>
Stars, or from it &longs;elf, it nece&longs;&longs;arily follows, that it cometh from <lb/>
the Sun. </s><s>Be&longs;ides that, if you do but grant this &longs;uppo&longs;ition, one <lb/>
may ea&longs;ily give convenient rea&longs;ons for all the particulars that <lb/>
occur. </s><s>For the rea&longs;on why that &longs;ecundary light &longs;hews more <lb/>
lively towards the outmo&longs;t limb, is, the &longs;hortne&longs;s of the &longs;pace <lb/>
that the Suns rays hath to penetrate, in regard that of the lines <lb/>
which pa&longs;s through a circle, the greate&longs;t is that which pa&longs;&longs;eth <lb/>
through the centre, and of the re&longs;t, tho&longs;e which are farthe&longs;t from <lb/>
it, are always le&longs;s than tho&longs;e that are nearer. </s><s>From the &longs;ame <lb/>
principle, he &longs;aith, may be &longs;hewn why the &longs;aid light doth not <lb/>
much dimini&longs;h. </s><s>And la&longs;tly, by this way the cau&longs;e is a&longs;&longs;igned <lb/>
whence it comes, that that &longs;ame more &longs;hining circle about the <lb/>
utmo&longs;t edge of the Moon, is &longs;een at the time of the Solar Ec <lb/>
clip&longs;e, in that part which lyeth ju&longs;t under the <emph type="italics"/>Di&longs;cus<emph.end type="italics"/> of the Sun, <lb/>
but not in that which is be&longs;ide the <emph type="italics"/>Di&longs;cus<emph.end type="italics"/>: which happeneth <lb/>
becau&longs;e the rays of the Sun pa&longs;s directly to our eye, through the <lb/>
