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 greater 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.
