extracting fluents out of Equations involving fluxions & at the request
of Dr Wallis sent it to him \in/

(exccept the Introduction & Conclusion) & when

And & when I had finished tenth Proposition wth
its Corollaries & the

Colours in the years 1665 & 1666
[illeg]
|&| in the year 1672
|1| was upon a
designe of publishing them,
[illeg] but so for a reason mentioned in my Letter of
24 Octob 1676 I forbore [illeg] publishing them till the year 16 1704.
|①| And that when I wrote in my Letter of 24 Octob. 1676 that the general
Theremes [sic] there mentioned for squaring of Curves were founded on the
Method of fluxions, I had relation to the method of finding them
described in the six first Propositions of the Book of Quadratures.
|③| The Introduction to the Book of Quadratures [where the Method of
fluxions is taught without the use of prickt letters is a demonstra] is
a demonstration that \I did not confine/ the Method of fluxions is not confined to prickt
Letters
\the method of fluxions is taught without pricket Letters & the letter o is used without both in the Introduction & in the Book it self without destroying the advantages of the ✝/
✝ the differention Notation, & the Notation by pricks is shorter then that by the
letter d, & the Notation by prik
|c|ks & the letter o together is more has more
advantages then that by the letter d & the first Proposition \of the Book/ is a demonstration that when I understood
all the degrees of fluxions when I wrote it, & my saying in the In-
troduction that I found the Method gradually in the years 1665 & 1666,
w which has occasioned all this squabble, is not so much as Dr Wallis
affirmed long before
\
nine years before long before/ in the Preface to the two first Volumes of his works
without being then contradicted by any body.
And that in the end of the year 1671 I invented the Method
of extracting fluents out of Equations involving fluxions \mentioned in my Letter of 24 Octob. 1676,/ & in the year
1676 I wrote the book fo Quadratures except the Introduction & Con-
clusion extracting most of it out of old Papers|.|
&
|And| when I wrote in my
Letter of 24 Octob 1676 that the general Theoremes there mentioned
for squaring of Curves were founded on the Method of fluxions, I
had relation to teh method of finding them described in the six
first Propositions of Qua the Book of Quadratures, And that [illeg]
\And/ when
I wrote \to Mr Collins/ my Letters of 8 Octob.
\Novem./ 1676 to Mr
published by Mr Iones
I had newly finished
\relation to/ the tenth Proposition of the Book of Quadratures
& had those things
\with it [sic] Corollaries wch
being then newly written were/ fresh in memory|.|
as may be perceived by comparing
the Letter with that Proposition & particularly with the second
Corollary
|ie|s thereof with that Letter \it self/ which was writ upon them. And
that I

the writi

ng the book of Principles I made very gr[e] by the
help of the book of Quadratures & in the year 1692 my
\two/ Letters of
\dated/ Aug 27 & Sep. 17 1692 I sent to Dr Wallis the method of fluxions
described in my the first Proposition of the book of Quadratures & the
method of extracting fluents out of equations involving fluxions \mentioned in my Letter of Octob 24, 1676/ both
which \methods/
t[h]
|w|ere printed the next year in the second Volume of the
Doctors works

\And that/ About the
same time that I invented the method of fluxions I invented also the
Theory of Colours vizt in the beginning of the year 167
|6|6 | winter between the years 1665 & 1666, & in the year
1671 I was upon a design of publishing both: but soon after laid aside
my designe
[illeg]
for a reason mentioned in my Letter of 24 Octob. 1676
