To which 'tis thought there needs no more to be said, to satisfie the observer, than that the Publisher did not at all obtrude another reason of the Effect, there spoken of, but very modestly (as he conceives) and with an expression implying doubt, suggested only his thoughts, which then occurr'd to him; being so unconcern'd herein, that, to shew on this occasion his averseness from disputing, he altogether leaves it to the Reader to judge, whether Similar Attraction, or Pulsion and Weight be the more Philosophical account of the Phænomenon, there discoursed of: In reference to which, this curious Travellor farther observes;

That the Sea-brise comes not into Jamaica till 8 or 9 of the clock in the morning, and ordinarily ceaseth about 4 or 5 at night.

And p. 498. he suggests, that for F. Hawkins it should be read Sir Richard Hawkins in his observ. Sect. 12.

Thirdly, he takes, notice, that he could not learn, how the Tor-
