h; (I mean, At Sea: for in Chanels it varies to all Hours, according as
they are neerer or further from the open Sea:) And the _Annual_ High-Tydes
of _November_ and _February_; somewhat later than {286} (what I conjecture
to be from the same causes) the greatest Inequalities of the natural Days,
happening in _January_ and _October_. But this though I can admit, yet
(till I am sure of the matter of Fact) I do not build upon. And since it
hath hitherto been the custome to speak with that laxness of expression;
assigning the times of New-moon, Full-moon, and Quadratures, with the Moons
comming to South, for, what is neer those times: I did not think myself
obliged in my conjectural Hypothesis (while it is yet but a _Candidate_) to
speak more nicely. If the Hypothesis for the maine of it be found Rational;
the Niceties of it are to be adjusted, in time, from particular
Observation.

Having thus given you some Answers to the Objections you signifie to have
been made by several persons to my Hypothesis, and that in the same order
your Paper presents them to me; I shall next give you some account of the
two _Books_, which you advised me to consult; so far as seems necessary to
this business; Which, upon your intimation, I have since perused, though
before I had not.

And first, as to that of _Isaac Vossius, De motu Marium & Ventorum_; Though
I do not concur with him in his Hypothesis; That all the _Great motions of
the Seas_, &c. should arise onely from _so small a warming of the water_ as
to raise it (where most of all) _not a Foot_ in perpendicular, (as in his
12_th_ Chapter.) Or that there is no other connexion between the Moons
motion, and the Tydes _menstrual_ period, than a _casual Synchronism_
(which seems to be the doctrine of his 16_th_ and 18_th_ Chapters;) Beside
many other things in his Philosophy, which I cannot allow: Yet I am well
enough pleased with what is Historical in it, of the matter of Fact:
Especially if I may be secure, that he is therein accurate and candid, not
wresting the _Phaenomena_ to his own purpose. But I find nothing in it,
which doth induce me to vary from my Hypothesis. For, granting his
Historicals to be all true; the account of the constant Current of the Sea
Westward, and of the constant Eastern Blasts, &c. within the _Tropicks_, is
much more plausibly, and (I suppose) truly rendered by _Galilaeo_ long
since, from the Earths _Diurnal_ motion: (which, neare the _AEquator_,
describing a gre
