1from Eaſt to Weſt, yet nevertheleſs the different Poſition of the
Shores may make part of the Water regurgitate, and return
backwards: I grant it you, but it is neceſſary that you take
tice my Simplicius, that where the Water upon that account
returneth backwards, it doth ſo there perpetually; and where
it runneth ſtraight forwards, it runneth there alwayes in the ſame
manner; for ſo the example of the Rivers ſhewes you: But in the
caſe of the ebbing and flowing, you muſt finde and give us ſome
reaſon why it doth in the ſelf ſame place run one while one way,
and another while another; Effects that being contrary & irregular,
can never be deduced from any uniform and conſtant Cauſe:
And this Argument, that overthrows the Hypotheſis of the
tion contributed to the Sea from the Heavens diurnal motion,
doth alſo confute that Poſition of thoſe who would admit the ſole
diurnal motion of the Earth, and believe that they are able with
that alone to give a reaſon of the Flux and Reflux: Of which
effect ſince it is irregular, the cauſe muſt of neceſſity be irregular
and alterable.
A reaſon of the
continual motion of
the Air and
ter may be given,
making the Earth
moveable, then by
making it
able.

the element of Fire
ſhould be carried

The Ebbing and
Flowing cannot
pend on the motion
of Heaven.
SIMP. I have nothing to reply, neither of my own, by reaſon
of the weakneſs of my underſtanding; nor of that of others, for
that the Opinion is ſo new: But I could believe that if it were
ſpread amongſt the Schools, there would not want Phyloſophers
able to oppoſe it.
SAGR. Expect ſuch an occaſion; and we in the mean time
if it ſeem good to Salviatus, will proceed forward.
SALV. All that which hath been ſaid hitherto, pertaineth to
the diurnal period of the ebbing and flowing; of which we have in
the firſt place demonſtrated in general the primary and univerſal
Cauſe, without which, no ſuch effect would follow: Afterw ds
paſſing to the particular Accidents, various, and in a certain ſort
irregular, that are obſerved therein: We have handled the
dary and concommitant Cauſes upon which they depend.
Now
follow the two other Periods, Monethly, and Annual, which do
not bring with them new and different Accidents, other than
thoſe already conſidered in the diurnal Period; but they
rate on the ſame Accidents, by rendring them greater and leſſer
in ſeveral parts of the Lunar Moneth, and in ſeveral times of
the Solar Year; as if that the Moon and Sun did each conceive
it ſelf apart in operating and producing of thoſe Effects; a thing
that totally claſheth with my underſtanding, which ſeeing how
that this of Seas is a local and ſenſible motion, made in an
menſe maſs of Water, it cannot be brought to ſubſcribe to
Lights, to temperate Heats, to predominacies by occult
ties, and to ſuch like vain Imaginations, that are ſo far from
ing, or being poſſible to be Cauſes of the Tide; that on the
