1other eminent aereal alteration that might occaſion the ſame; of
which diſturbance of the Air we ought to make great account
in other accidents, and to take it for a third and accidental
cauſe, able to alter very much the obſervation of the effects
pending on the ſecondary and more eſſential cauſes. And it is
not to be doubted, but that impetuous windes, continuing to
blow, for example, from the Eaſt, they ſhall retein the Waters
and prohibit the reflux or ebbing; whereupon the ſecond and
third reply of the flux or tide overtaking the former, at the
hours prefixed, they will ſwell very high; and being thus born
up for ſome dayes, by the ſtrength of the Winds, they ſhall riſe
more than uſual, making extraordinary inundations.

We ought alſo, (and this ſhall ſerve for a ſeventh Probleme)
to take notice of another cauſe of motion dependant on the
great abundance of the Waters of great Rivers that diſcharge
to take notice of another cauſe of motion dependant on the
great abundance of the Waters of great Rivers that diſcharge
themſelves into Seas of no great capacity, whereupon in the
Straits or Boſphori that communicate with thoſe Seas, the Waters
are ſeen to run always one way: as it happeneth in the
an Boſphorus below Conſtantinople, where the water alwayes
runneth from the Black-Sea, towards the Propontis: For in the
ſaid Black-Sea by reaſon of its ſhortneſſe, the principal cauſes
of ebbing and flowing are but of ſmall force. But, on the
trary, very great Rivers falling into the ſame, thoſe huge
fluxions of water being to paſſe and diſgorge themſelves by the
the Straight, the ^{*}courſe is there very notable and alwayes
wards the South. Where moreover we ought to take notice, that
the ſaid Straight or Channel, albeit very narrow, is not ſubject
to perturbations, as the Straight of Soilla and Carybdis; for that
that hath the Black-Sea above towards the North, and the
pontis, the Ægean, and the Mediterranean Seas joyned unto it,
though by a long tract towards the South; but now, as we have
obſerved, the Seas, though of never ſo great length, lying North
and South, are not much ſubject to ebbings and flowings; but
becauſe the Sicilian Straight is ſituate between the parts of the
Mediterrane diſtended for a long tract or diſtance from Weſt to
Eaſt, that is, according to the courſe of the fluxes and refluxes,
therefore in this the agitations are very great; and would be
much more violent between Hercules Pillars, in caſe the
Straight of Gibraltar did open leſſe; and thoſe of the Straight of
Magellanes are reported to be extraordinary violent.
This is what, for the preſent, cometh into my mind to ſay unto
you about the cauſes of this firſt period diurnal of the Tide, and
its various accidents, touching which, if you have any thing to
offer, you may let us hear it, that ſo we may afterwards
ceed to the other two periods, monethly and annual.
