         EEBO-TCP is a partnership between the Universities of Michigan and Oxford and the publisher ProQuest to create accurately transcribed and encoded texts based on the image sets published by ProQuest via their Early English Books Online (EEBO) database (http://eebo.chadwyck.com). The general aim of EEBO-TCP is to encode one copy (usually the first edition) of every monographic English-language title published between 1473 and 1700 available in EEBO.
         EEBO-TCP aimed to produce large quantities of textual data within the usual project restraints of time and funding, and therefore chose to create diplomatic transcriptions (as opposed to critical editions) with light-touch, mainly structural encoding based on the Text Encoding Initiative (http://www.tei-c.org).
         The EEBO-TCP project was divided into two phases. The 25,363 texts created during Phase 1 of the project have been released into the public domain as of 1 January 2015. Anyone can now take and use these texts for their own purposes, but we respectfully request that due credit and attribution is given to their original source.
         Users should be aware of the process of creating the TCP texts, and therefore of any assumptions that can be made about the data.
         Text selection was based on the New Cambridge Bibliography of English Literature (NCBEL). If an author (or for an anonymous work, the title) appears in NCBEL, then their works are eligible for inclusion. Selection was intended to range over a wide variety of subject areas, to reflect the true nature of the print record of the period. In general, first editions of a works in English were prioritized, although there are a number of works in other languages, notably Latin and Welsh, included and sometimes a second or later edition of a work was chosen if there was a compelling reason to do so.
         Image sets were sent to external keying companies for transcription and basic encoding. Quality assurance was then carried out by editorial teams in Oxford and Michigan. 5% (or 5 pages, whichever is the greater) of each text was proofread for accuracy and those which did not meet QA standards were returned to the keyers to be redone. After proofreading, the encoding was enhanced and/or corrected and characters marked as illegible were corrected where possible up to a limit of 100 instances per text. Any remaining illegibles were encoded as <gap>s. Understanding these processes should make clear that, while the overall quality of TCP data is very good, some errors will remain and some readable characters will be marked as illegible. Users should bear in mind that in all likelihood such instances will never have been looked at by a TCP editor.
         The texts were encoded and linked to page images in accordance with level 4 of the TEI in Libraries guidelines.
         Copies of the texts have been issued variously as SGML (TCP schema; ASCII text with mnemonic sdata character entities); displayable XML (TCP schema; characters represented either as UTF-8 Unicode or text strings within braces); or lossless XML (TEI P5, characters represented either as UTF-8 Unicode or TEI g elements).

           As
           first
           ,
           A
           reason
           is
           given
           why
           we
           have
           two
           Tides
           upon

           hours

           Secondly
           ,
           Why
           those
           Tides
           fall
           exactly
           so
           many
           Minutes
           later
           every
           day
           ,
           as
           the
           Moon
           doth
           .
           Thirdly
           ,
           By
           what
           meanes
           these
           Tides
           are
           made
           to
           Increase
           &
           decrease
           every
           seven
           days
           &
           why
           they
           are
           always
           highest
           when
           the
           Moon

           on
           Neighbouring
           shores
           they

           In
           the

           usual
           Confidence

           perswading
           my self
           that
           the
           hopes
           of
           being
           made
           acquainted
           with
           this
           great
           Secret
           ,
           will
           engage
           you
           to
           take
           a
           little
           pains
           more
           then
           ordinary
           to
           understand
           my
           meaning
           ,
           which
           if
           you
           once
           do
           ,
           you
           and
           I
           shall
           quickly
           be
           agreed
           ;
           you
           will
           then
           say
           ●
           that
           you
           know
           the
           true
           cause
           of
           the
           Ebbing
           and
           Flowing
           of
           the
           Sea.
           
        
         
         
           If
           you
           think
           that
           I
           have
           made
           more
           words
           then
           needed
           about
           some
           things
           ,
           impute
           it
           to
           my
           fear
           that
           otherways
           I
           should
           not
           be
           understood
           ,
           or
           to
           my
           Ignorance
           not
           knowing
           the
           most
           expressive
           words
           ,
           the
           shortest
           way
           .
           If
           in
           other
           things
           I
           am
           as
           much
           or
           more
           too
           short
           ,
           be
           so
           kind
           as
           to
           excuse
           me
           by
           thinking
           what
           your self
           would
           do
           in
           the
           same
           case
           ;
           and
           in
           this
           I
           am
           sure
           you
           will
           be
           of
           my
           mind
           ,
           that
           is
           ,
           that
           he
           that
           knows
           he
           does
           not
           speak
           well
           ,
           should
           say
           as
           little
           as
           he
           can
           .
           And
           upon
           that
           account
           I
           have
           not
           troubled
           you
           ,
           nor
           concerned
           my self
           with
           any
           thing
           that
           I
           could

           ways
           avoy'd

           Amongst
           many
           other
           defects
           you
           will
           find
           that
           my
           Ignorance
           in
           the
           Mathematicks
           ,
           as
           well
           as
           other
           parts
           of
           Learning
           ,
           has
           forc't
           me
           instead
           of
           Terms
           of
           Art
           (
           which
           would
           have
           been
           much
           better
           understood

           to
           make
           use
           of
           such
           Words

           Terms

           being
           known
           to
           me
           ,
           I
           thought
           might
           best
           express
           my
           thoughts
           to
           others
           :
           perhaps
           you
           will
           think
           that
           a
           very
           little
           time
           and
           pains
           in
           that
           Study
           might
           have
           enabled
           me
           to
           have
           set
           this
           off
           much
           more
           advantagiously
           ,
           I
           am
           of
           the
           same
           mind
           ,
           but
           the
           circumstances
           I
           stand
           in
           have
           not
           yet
           afforded
           me
           that
           time
           .
           But
           I
           tell
           you
           again
           ,
           you
           shall
           find
           the
           thing
           it self
           to
           be
           true
           ,
           and
           then
           surely
           you
           will
           not
           be
           angry
           with
           me
           for
           these

           presently
           bring
           me
           to
           a
           place

           way
           he

           yet
           if
           at
           last
           he
           put
           me
           in

           Riches

           I
           would
           certainly
           ,
           by

             THE

             that

             well
             considered

             question

             far
             from
             any
             thing

             just
             before
             you
             thought
             strange

             you
             will
             then
             think
             not
             only
             easy
             but
             reasonable

             In

             mean
             time
             you
             may
             consider

             such

             exactly
             observe
             the
             Motions
             of

             was
             continued

             the

             three

             And
             now
             the
             motion
             will
             be
             back
             again
             the
             next
             six

             look
             how
             much
             advantage
             the
             moon
             gained
             by
             drawing
             by
             lines
             successively
             more
             upright

             so
             much
             she
             now
             must
             lose
             by
             drawing
             by
             lines
             more
             declining

             So
             that

             the

             the

             of
             the
             Earth
             must
             be

             and
             when
             the

             the

             then
             will
             the

             it
             was
             when
             the

             But
             now
             as
             when
             the
             moon
             was
             in

             the

             not

             for

             this

             know
             that
             when
             I
             had
             well
             considered
             the
             excellent
             agreement
             between
             the

             of
             the
             Earth

             as
             I
             had
             supposed
             it

             and
             the
             Seas
             ,
             It
             came
             presently
             in
             my
             mind
             that
             by
             making
             a
             light
             Globe
             ,
             and
             setting

             upon
             its
             Poles
             so
             tenderly
             ballanc't
             that
             it
             might
             but
             just
             
             have
             a
             Tendancy
             the

             way

             I
             might
             inform
             my self
             by
             the
             help
             of
             a
             Loadstone
             ,
             which
             would
             admirably
             suppply

             the

             carried

             round
             the

             would
             give
             it
             ,
             and
             how
             it
             would
             agree
             with
             the
             motion
             I
             had
             suppos'd
             the
             earth
             to
             have
             ,
             but
             unexpected
             and
             succeeding
             ,
             troubles
             kept
             me
             at
             least
             three
             years
             otherways

             but
             then
             I
             made
             a

             which
             was
             the

             But
             the
             Satisfaction
             I
             received
             by
             this

             artificially
             made

             but
             unwelcom
             accidents

             I
             doubt
             not

             be
             so
             posited

             directly

             how

             the

             as
             he
             comes
             to

             I
             will
             now
             examine

             much
             the

             Action
             ,
             which
             may
             easily
             be

             That
             when
             the
             Moon
             is
             90
             degrees
             from

             the

             directly
             opposes
             the

             in

             and
             yet
             then
             the
             Tides
             here
             at
             London

             full
             Moon
             the
             Sun
             lends
             his
             utmost
             Assistance
             ,
             and
             then
             they

             now
             if

             16.
             its
             certain
             that
             if
             the
             Sun
             did
             neither
             hinder
             nor

             the
             Moon
             alone
             would
             give
             the
             Earth
             so
             much
             motion

             should
             constantly

             So
             that
             the
             Suns
             interest
             can
             be

             speak
             of

             but
             this
             is

             You

             Tides
             should
             not
             increase
             after
             New
             and
             Full-Moon
             ,
             at
             least
             not
             so
             long
             .
          
           
             I
             have
             made
             some
             agreeable
             observations
             about
             this
             ,
             but
             have
             not
             had
             time
             for
             a
             strict
             inquiry
             ;
             though
             I
             have
             long
             thought
             of
             it
             .
             Those
             that
             live
             near
             this
             ,
             or
             any
             other
             River
             that
             Ebbs
             and
             Flows
             ,
             may
             easily
             inform
             themselves
             whether
             this
             be
             so
             or
             no.
             
          
           
             But
             now
             besides
             these
             alterations
             of
             the
             Seas
             ,
             it
             must
             follow
             upon
             this
             motion
             of
             the
             Earth
             :
             first
             ,
             that
             when
             the
             Tides
             rise
             highest
             ,
             they
             must
             fall
             lowest
             ;
             Secondly
             ,
             That
             the
             Tides
             in
             all
             Seas
             must
             set
             East
             and
             West
             ;
             and
             Thirdly
             ,
             That
             the
             motion
             of
             the
             Seas
             must
             begin
             at
             the
             same
             time
             all
             over
             the
             World.
             
          
           
             The
             first
             of
             these
             you
             may
             at
             your
             pleasure
             observe
             ,
             and
             
             you
             shall
             alwayes
             find
             that
             the
             highest
             spring
             .
             Tide
             makes
             the
             lowest
             Ebb.
             And
             all
             experimene'd
             men
             know
             the
             Tides
             set
             directly
             East
             and
             West
             upon
             all
             the
             utmost
             Eastern
             and
             Western
             Shores
             in
             the
             World.
             And
             I
             think
             that
             Learned
             men
             are
             agreed
             ,
             that
             the
             motion
             begins
             at
             the
             same
             time
             in
             all
             Seas
             .
             Thus
             much
             is
             certain
             ,
             that
             when
             the
             Moon
             is
             South-west
             ,
             or
             in
             the
             opposite
             Point
             of
             the
             Heavens
             ,
             that
             is
             North-east
             ,
             it
             is
             alwaies
             high-water
             upon
             all
             the
             utmost
             open
             western
             Shores
             of
             Europe
             and
             Affrica
             ,
             from
             
               Nova
               Zembla
            
             to
             the
             Cape
             of
             Good-hope
             .
             And
             that
             when
             the
             Moon
             is
             South-east
             or
             North-west
             ,
             it
             is
             high-water
             upon
             the
             utmost
             Eastern
             Shores
             of
             America
             .
             So
             that
             when
             it
             is
             high-water
             upon
             the
             first
             named
             ,
             it
             must
             be
             low-water
             upon
             the
             other
             Shores.
             When
             they
             have
             the
             first
             of
             Ebb
             upon
             the
             Western
             Shores
             of
             Europe
             and
             Affrica
             ,
             they
             must
             have
             the
             first
             of
             Flood
             upon
             the
             opposite
             Eastern
             Shores
             of
             America
             .
             By
             which
             it
             is
             plain
             that
             the
             motion
             begins
             at
             the
             same
             time
             in
             all
             these
             Seas
             ;
             and
             that
             what
             we
             call
             the
             Ebbing
             and
             Flowing
             of
             the
             Sea
             ,
             is
             nothing
             but
             the
             falling
             of
             the
             waters
             from
             off
             the
             Western
             ,
             upon
             the
             Eastern
             Shores
             ,
             and
             the
             same
             back
             again
             every
             6
             hours
             .
             But
             further
             ,
             when
             it
             is
             high-water
             upon
             the
             Western
             Shores
             of
             Europe
             and
             Affrica
             ,
             it
             is
             high-water
             at
             the
             same
             time
             upon
             the
             Western
             Shores
             of
             Italy
             ,
             and
             upon
             the
             Shores
             of
             Syria
             at
             the
             bottom
             of
             the
             Mediteranean
             Sea
             ,
             and
             (
             take
             good
             notice
             of
             it
             )
             when
             it
             is
             high-water
             upon
             those
             Shores
             ,
             it
             is
             low-water
             at
             Venice
             and
             on
             the
             contrary
             .
             Now
             this
             I
             take
             to
             be
             a
             very
             forceable
             argument
             to
             prove
             the
             motion
             of
             the
             Earth
             ,
             as
             I
             have
             supposed
             it
             ,
             and
             then
             the
             motion
             must
             begin
             at
             the
             same
             time
             in
             all
             Seas
             ;
             for
             it
             is
             unconceivable
             how
             this
             should
             otherwise
             happen
             :
             but
             if
             you
             shall
             fancy
             the
             Terraqueous
             Globe
             to
             have
             a
             little
             motion
             from
             West
             to
             East
             ,
             you
             will
             then
             say
             that
             it
             must
             make
             high-water
             upon

             A
             reason

             Why
             upon

             when
             upon

             have
             great

             attempting
             to
             give
             a
             reason
             why
             it

             being
             almost
             confident
             that
             when
             you

             you

             say

             it

             about

             years
             since

             I
             concluded

             upon

             the
             Reason
             of
             those
             Alterations
             would
             manifestly
             appear
             ,
             I
             should
             have
             made
             some
             words
             about
             it
             .
             )
             And
             the
             motion
             of
             the
             Waters
             shall
             be
             in
             Proportion
             to
             the
             largeness
             of
             the
             Vessels
             ,
             only
             it
             shall
             be
             insensible
             in
             that
             narrow
             Vessel
             that
             stood
             North
             and
             South
             in
             the
             Boat.
             Then
             it
             will
             not
             at
             all
             seem
             strange
             to
             you
             that
             the
             Alterations
             observ'd
             in
             other
             parts
             of
             the
             Ocean

             not
             discernable
             in
             the
             Baltick
             Sea.
             And
             I
             know
             that
             you
             think
             it
             would
             be
             the
             same
             thing
             if
             that
             Sea
             was
             plac't
             at
             either
             of
             the
             Poles

             or
             at
             the
             Equator
             :
             And
             that
             if
             the
             Mediteranean
             Sea
             stood
             as
             the
             Baltick
             ;
             North
             and
             South
             ,
             that
             there
             would
             be
             very
             little
             or
             no
             Tides
             in
             that
             Sea

             But
             to
             be
             sure
             there
             could
             be
             none
             where
             now
             they
             have
             the
             greatest
             Tides
             ,
             that
             is
             ,
             upon
             the
             shores
             of
             
               Syria

             Streights
             mouth
             .
             And
             that
             if
             the
             Baltick
             Sea
             was
             plac't
             East

             ,
             the
             tides
             would
             be
             discernable
             enough
             in
             the
             Extremities
             of

             To
             conclude
             ,
             I
             lately
             met
             with
             a
             couple
             of
             Observations
             about
             the
             ebbing
             and
             flowing
             of
             the
             Sea
             in
             the
             Philosophical
             Transactions
             of
             the
             truly
             Royal
             Society
             ,
             not
             yet
             spoken
             of
             the
             first
             is
             :
             That
             the
             water
             neither
             flows
             nor
             ebbs
             alike
             ,
             in
             Respect
             of
             equal
             Degrees
             ,
             but
             its
             Velocity
             increaseth
             with
             the
             tide
             till
             just
             mid-water
             or
             half-flood
             ,
             at
             which
             time
             its
             Velocity
             is
             at
             the
             Strongest
             ;
             and
             then
             decreaseth
             proportionably
             till
             high-water

             full
             Sea.
             
          
           
             If
             you
             have
             understood
             what
             I
             have
             said
             ,
             you
             cannot
             but
             know
             that
             the
             first
             three
             hours
             of
             every
             flood
             and
             ebb
             is
             that
             three
             hours
             time
             in
             which
             the
             earth
             is
             returning

             its
             Level
             ;
             then
             the
             business
             is
             to
             know
             whether
             it
             may
             be
             thought
             that
             the
             Moon

             somwhat
             quicker
             ,
             then
             she
             raises
             it
             .
             Or
             ,
             that
             the
             waters
             falling
             upon
             the
             empty
             shores
             ,
             must
             be
             thought
             to
             rise
             faster
             the
             first
             three
             hours
             ,
             then
             they
             can
             when
             the
             shores

             half
             full
             .
             I
             must
             leave
             this
             to
             the
             Determination
             of
             wiser
             men

             The
             other
             Observation
             is
             indeed
             very
             notable
             ,
             which
             is

             that

             then
             the
             evening
             tides

             on
             the
             contrary
             the
             other
             half
             year
             .
          
           
             It
             would
             trouble
             a
             good
             head
             to
             give
             a
             Satisfactory
             Reason
             how
             this
             should
             happen
             ,
             if
             the

             not
             such

             as
             I
             have
             been
             speaking
             of
             ;
             but
             that
             being
             alow'd

             the
             cause
             of
             this
             odd
             effect
             is
             manifest
             enough
             .
             Nay
             I
             am
             perswaded
             that
             the
             solving
             of
             this
             doubt

             because
