■plication of caufes. For (as we before fhe.wed in the Menfirud 
and Diurnal) there will, by this inequality of Natural daies, arife 
a Pbyfical Acceleration and Retardation of the Earths Mean 
motion, and accordingly a calling of the Waters backward or 
forward 5 either of which, will caufe an-Accumiriation or High- 
water. 
’Tis true, that thefe longeft and fhorteft daies, do (according 
to theT ablest fome at leaftj fall rather before , than after Al- 
, hallontide and Candlemas^ to wit the ends of OBober and January,} 
but fo do alfo (fometimes)thofe high Tydes : And it is not yet 
fo well agreed amongR^/ww^r/, what are all the Caufes(and 
in what degrees_)of the Inequality of Natural daies; but that 
there be diverfities among them, about the true time : And whe- 
ther the introducing of this New Motion of the Earth in its 
Epicycle about this Common Center of Gravity, ought not there- 
to alfo to be accounted for, I will not now determine: Having 
already faid enough, if not too much , for the explaining of 
this general Hypothecs , leaving the particularities of it to be 
adjufted according to the true meafures of the motions ; if the 
General Hypothefis be found fit to be admitted. 
Yet this I mu ft add 1 , ( that I be not miftaken) that whereas 
I call the time of the daily Tydes to be at all places, when the 
Moon is there in the Meridian; itmuft be underftood of open 
Seas; where the water hath fuch free fcope for its motions, as 
if the whole Globe of Earth were equally covered with water : 
Well knowing, that in Bayes and In l and- Channels, the polition of 
the Banks and other like caufes rau ft needs make the times to 
be much different from what we fuppofe in the open Seas : And 
Iikewife,that even in the Open Seas, IJlands , and Currents , Gulfs 
and Shallows , may have fome influence, though not compara- 
ble to that of Bays and Channels . And moreover, though I 
think, that Seamen do commonly reckon the time of High- 
water in the Open Seas, to be then , when the Moon is there in 
the Meridian (as this Hypothefis would caftit :) Yet I do not 
take my felf to be fo well furnifhed with a Hiflery of Tides , as to 
allure my felf of it; much lefs to accommodate it to particular 
places and cafes. 
Having thus difpatched the main of what I had to fay con-
