ing deprived of the progreſſion dependant on the diurnal motion:
If we ſuppoſe, I ſay, a tract of Sea as long as the arch B C, we
have already ſeen, that its extreams ſhall move in the ſame time
with great inequality. And extreamly different would the
cities of a tract of Sea be that is in length a ſemicircle, and
ced in the poſition B C D, in regard that the extream B would
be in a moſt accelerate motion, and the other D, in a moſt ſlow
one; and the intermediate parts towards C, would be in a
moderate motion. And according as the ſaid tracts of Sea ſhall
be ſhorter, they ſhall leſſe participate of this extravagant
dent, of being in ſome hours of the day with their parts diverſly
affected by velocity and tardity of motion. So that, if, as in the firſt
caſe, we ſee by experience that the acceleration and retardation,
though equally imparted to all the parts of the conteining Veſſel,
is the cauſe that the water contained, fluctuates too and again, what
may we think would happen in a Veſſel ſo admirably diſpoſed,
that retardation and acceleration of motion is very unequally
contributed to its parts? Certainly we muſt needs grant that
greater and more wonderful cauſes of the commotions in the
Water ought to be looked for. And though it may ſeem
poſſible to ſome, that in artificial Machines and Veſſels we ſhould

SAGR. I for my own particular very well conceive that this
admirable accident ought neceſſarily to evene in the Straights of
Seas, and eſpecially in thoſe that diſtend themſelves for a great
length from Weſt to Eaſt; namely according to the courſe of
the motions of the Terreſtrial Globe; and as it is in a certain
manner unthought of, and without a preſident among the
ons poſſible to be made by us, ſo it is not hard for me to believe,
that effects may be derived from the ſame, which are not to be
mitated by our artificial experiments.
