But the true _Inequality_ of the Natural Days, arising from a _Complication of those two causes_, sometimes crossing and sometimes promoting each each other: though we should find some increases or decreases of the _Natural_ daies at all those seasons answerable to the respective causes (and perhaps of Tides proportionably thereunto:) yet the longest and shortest _natural daies_ absolutely of the whole year (arising from this complication of Causes) are about those times of _Allhallontide_ and _Candlemas_; (or not far from them) about which those _Annual_ High-tides are found to be: As will appear by the _Tables of AEquation_ of _Natural_ daies. And therefore I think, we may with very good reason cast this _Annual_ Period upon that cause, or rather {279} complication of causes. For (as we before shewed in the _Menstrual_ and _Diurnal_) there will, by this inequality of Natural daies, arise a _Physical_ Acceleration and Retardation of the Earths _Mean_ motion, and accordingly a casting of the Waters backward or forward; either of which, will cause an Accumulation or High-water. 'Tis true, that these longest and shortest daies, do (according to the _Tables_, some at least) fall rather before, than after _Alhallontide_ and _Candlemas_ (to wit the ends of _October_ and _January_;) but so do also (sometimes) those high Tydes: And it is not yet so well agreed amongst _Astronomers_, what are all the Causes (and in what degrees) of the Inequality of Natural daies; but that there be diversities among them, about the true time: And whether the introducing of this New Motion of the Earth in its _Epicycle_ about this Common Center of _Gravity_, ought not therein also to be accounted for, I will not now determine: Having already said enough, if not too much, for the explaining of this general Hypothesis, leaving the particularities of it to be adjusted according to the true measures of the motions; if the General Hypothesis be found fit to be admitted.
