ater Circle, than nearer the {287} _Poles_, makes the
Current to be there more conspicuous and swift, and consequently, the Eddy,
or recurrent motion, nearer the Poles, where this is, more remiss:) than
can easily be rendered by so small a Tumor, as he supposeth. Not to adde;
that his account of the Progressive motion, which he fansieth to follow
upon this Tumefaction, and by Acceleration to grow to so great a height
near the Shoar (as in Chap. 13. and 14.) is a Notion, which seems to me too
extravagant to be salved by any laws of _Staticks_. And that of the Moons
motion onely Synchronizing with the Tydes, casually, without any _Physical_
connexion; I can very hardly assent to. For it can hardly be imagined, that
any such constant _Synchronisme_ should be in Nature; but where, either the
one is the cause of the other, or both depend upon some _Common_ cause. And
where we see so fair a foundation for a _Physical_ connection. I am not
prone to ascribe it to an Independent Sychronism. In sum; His History doth
well enough agree with my Hypothesis; and I think, the Phaenomena are much
better salved by mine, than his.

And then as to _Gassendus_, in his discourse _De AEstu Maris_; I find him,
after the relating of many other Opinions concerning the Cause of it,
inclining to that of _Galilaeo_, ascribing it to the Acceleration &
Retardation of the Earths motion, compounded of the Annual and Diurnal; And
moreover attempting to give an account of the _Menstrual Periods_ from the
Earths carrying the Moon about it self, as _Jupiter_ doth his _Satellites_;
which together with them is carryed about by the _Sun_, as one Aggregate;
(and that the Earth with its Moon is to be supposed in like manner to be
carried about by the Sun, as one Aggregate, cannot be reasonably doubted,
by those who entertain the _Copernican Hypothesis_, and do allow the same
of _Jupiter_ and his _Satellites_.) But though he would thus have the Earth
and Moon looked upon as two parts of the same moved Aggregate, yet he doth
still suppose (as _Galilaeo_ had done before him) that the line of the Mean
Motion of this Aggregate (or, as he calls, _motus aequabilis et veluti
medius_) is described by the _Center_ of the _Earth_ (about which Center he
supposeth both its own revolution to be made, and an Epicycle described by
the Moons motion;) not by another Point, distinct from the Centers of both,
about which, as the {288} common Center of Gravity, as well that of the
Ea
