neſſe of the Veſſel, in its acquiring in ſeveral hours of the day
ſeveral degrees of velocity, they are with very little difference
acquired by all its parts; for as well the precedent as the
quent, that is to ſay, both the Eaſtern and Weſtern parts, do
accelerate and retard almoſt in the ſame manner; and withal
making that alteration by little and little, and not by giving the
motion of the conteining Veſſel a ſudden check, and
ment, or a ſudden and great impulſe or acceleration; both it
and all its parts, come to be gently and equally impreſſed with
the ſame degrees of velocity; from which uniformity it
eth, that alſo the conteined water with but ſmall reſiſtance and
oppoſition, receiveth the ſame impreſſions, and by conſequence
doth give but very obſcure ſignes of its riſing or falling, or of its
running towards one part or another. The which effect is likewiſe
manifeſtly to be ſeen in the little artificial Veſſels, wherein the
contained water doth receive the ſelf ſame impreſſions of
ty; when ever the acceleration and retardation is made by gentle
and uniform proportion. But in the Straights and Bays that for a
great length diſtend themſelves from Eaſt to Weſt, the
ration and retardation is more notable and more uneven, for
that one of its extreams ſhall be much retarded in motion, and
the other ſhall at the ſame time move very ſwiftly: The
procal libration or levelling of the water proceeding from the
petus that it had conceived from the motion of its container.
The which libration, as hath been noted, hath its undulations
very frequent in ſmall Veſſels; from whence enſues, that though
there do reſide in the Terreſtrial motions the cauſe of
ring on the waters a motion onely from twelve hours to twelve
hours, for that the motion of the conteining Veſſels do
treamly accelerate and extreamly retard but once every day,
and no more; yet nevertheleſſe this ſame ſecond cauſe

equilibration, and that according to the ſhortneſſe of the
ſel hath its reciprocations of one, two, three, or more hours, this
intermixing with the firſt, which alſo it ſelf in ſmall Veſſels is
very little, it becommeth upon the whole altogether inſenſible.
For the primary cauſe, which hath the periods of twelve hours,
having not made an end of imprinting the precedent
on, it is overtaken and oppoſed by the other ſecond,

and profundity of the Veſſel, hath the time of its undulations of
one, two, three, four, or more hours; and this contending
with the other former one, diſturbeth and removeth it, not
mitting it to come to the height, no nor to the half of its
