And whereas in another paper published by Dr Menkenius in the Acta Eruditorum for Ian. 16705, in giving an Account of the book De quadratura Curvarum the Book is accused of as a piece of Plagiary, in these words; Ingeniosissimus deinde author [Newtonus] antequam ad Quadraturas Curvarum vel potius Figurarum Curvilinearum) veniat, præmittit brevem Isagogem. Quæ ut melius MELIVS intelligatur, sciendum est, cum magnitudo aliqua continuo crescit, verbati Linea exempli gratia incrementa illa momentanea appellari differentias, nempe inter magnitudinem quæ antea erat & quæ per mutationem momentaneam est producta; atque hinc natum est cCalculum Differentialem, eique reciprocum summatorium; cujus elementa ab INVENTORE D.

Dr Menkenius who published this defamatory Paper is desired to discover the name of tell the world who was the Author.
And
And because whereas in the aforesaid Letter of 7 Iune 1713 ascribed by Mr Leibnitz to Mr Iohn Bernoulli, this accusation of plagiary is pursued, & the world is told that Mr Newton did not so much as dream of the Calculus of fluxions when he wrote the ancient Letters & Papers published in the Commercium Epistolicum, ② no nor in when he wrote his Principia Naturæ Mathematica nor long after, ① because there are no prickt letters in them ③ & that these because these Letters First appeared in the third Volume of Wallises works many years after the Differential Calculus was every where known,] & because that] Mr Newton when he wrote his Principles did not then understand how to find second differences as he pretends till it was familiar to others: Mr Bernoulli is desired to look into the second Volume of the Works of Dr Wallis pag. 391 392, 393 &c & then tell the wordld whether prickt Letters did not come abroad in the year 1693 six years before the third Volume was published & whether the first Proposition of the book of Quadratures with the solution & examples in first & second differences fluxions be not there published almost verbatim & whether the Rule there given for finding second third & fourth fluxions &c be not genuine & did not come abroad some years before any Rule for finding second third & fourth differences & whether the method of fluxions be not taught in yethe Introduction to the very book of Quadratures without the use of prickt letters: For as he has publickly accused Mr Newton of Plagiary by feigned pretences so he ought to justif make a publick Recantation if his accusation be not true.
And whereas Mr Bernoull it is pretended that an Italian named Ricatti has made many experiments with Prisms & L Lenses & Prisms of crystal of yethe Rock, wchwhich destroy the Theory of Hypothesis of Mr Newton about apparent colours: & yet yet Mr Newton assumes no expe hypothesis & Prisms of crystall are unfit for exp such yet instead of sending an experiment of that kind to prove his assertion has sent a chalenge to solve a Mathematical Probleme & thereby discovered that he is in a confederatcy wthwith Mr Bernoulli, & yet Mr Newton assumes no hypothesis nor meddles with apparent colours & Prisms of Crystall are unfit for s by reason of a double refraction are unfit for such purposes experimtsexperiments & Mr Ricatti instead of sending an experiment to prove his assertion, has sent a ma challenge to solve a mathematical Probleme & thereby discovered that he is in a confederacy with Mr Bernoulli, & upon these considerations he is looked upon here by some as a Pretender & a bullying Pretender: he is desired to: for clearing himself from this imputation he is desired to publish communicate to the world any one of his experiments wchwhich contradicts Mr Newton's Theory.
Mr Raphson a little before his death published that the Book of Quadratures published wchwhich came abroad in the year 16 1714 1704, was about the year 1676 extracted written from a former Tract, & that about the year 1691 MDr Halley & he had it in their hands at Cambridge about the year 1691 in order to bring it up to London; & Dr Halley remembers that this was presently after the election of Mr Raphson into the R. Society, wchwhich was in 1690. And therefore the Book was written before Mr Bernoulli knew any thing of the Differential Method, & for heim to accuse it of Plagiary is to tell the wolrld that he has a mind to something that is in it. It is easy to add to inventions, & if he has improved it the method the is desired p improvements are his own, & he is desired to publish them & such he is at liberty to publish them when ever he pleases. But with And But the honnour practise of challenging vanity introduced by him & Mr Leibnitz of challenging every body to solve their Problems, is not in England has not yet obteined in England, & we look up it with contempt.

Whereas a wrangling Paper was published in the Acta Eruditorūum for Iuly 1716 — who is the author thereof. And whereas in the same paper.

The first Proposition of this Book was in with it solution & examples in first & second fluxions was published almost verbatim by Dr Wallis in the second Volume of this Drs works A.C. 1693, being sent to the Doctor the year before, & therefore th & printed off the year before; & therefore the Book was then in manuscript. Mr Raphson has published that he Dr Halley & he had it in their hands at Cambridge about the year 1691 in order to bring it up to London & Dr. Halley rembersremembers that it was in A.C. 1690 & thence it may be understood that it was in MS before the Rules invented & composed by Mr Bernoulli. There In Mr Newtons Letters of Iune 13 Octob. 24th & Novem 8th 1676 there are many things relating to this Book & therefore it was in Manuscript before Mr Leibnitz knew any thing of the Differential Method.
In this Book are many things which had they been proposed as Problems to be solved, might have puzzelled all the Mathematicians in Europe, as for instance to integrate the quantities, + c y the areas of the Curves exprest by the following equations whose areas are [integrate reduce the integration of following to the quadrature of find the Conic Sections in the following equations in the following equations . Or to reduce the integration of to the simplest cases of quadratures in the following equations .

Obs. Mr Newton is here accused of Plagiary by a mere conjecture jecture contrary to the authority testimony of an abler & older Mathematician Dr Wallis in the Preface to the first volume of his works cited above pag. 105, 106.

Obs. In the second Lemma of the second Book of Principles the Elements of the Book Method of fluxions are taught, & in the Introduction to the Book of Quadratures the method it self is expresly taught & illustrated by Examples & all this is done wthwithout the use of prickt letters. And in Mr Newton's Letter 10 Decem. 1672 the method is sufficiently described.
Artic. 3.
Observatons upon the foregoing Letter.
Dr Wallis an older & abler Mathematician has attested in the Preface to the first Volume of his works that this Method was Mr Newton explained this Method to Mr L . . . . z in his Letters of 13 Iune & 24 Octob. 1676 & invented it ten years before or above In the second Lemma of the second Book of Princi Mathematical Principles the Elements of this Method of fluxions are demonstrated taught & demonstrated; & in the Introduction to the book of Quadratures the Method it self is taught & il expresly taught & illustrated by examples, & in Mr Newtons Letter of 10 Decem 1672 the Method is plainly described & illustrated with an example of Drawing Tangents thereby: & all this is done without the use of prickt letters. The Book of Principles was writ by Composition & therefore therefore there was no occasion of using the calculus of fluxions in it. Prickt letters appeared in the second Volume of the works of Dr Wallis, & this Volume was almost all printed in the year 1692 & came abroad the next spring before the Differential method began to make a noise. The Manuscript of the Book of Quadratures came abroad was in the hands of Dr Halley & Mr Ralpshson in the year 1691 as both of them have attested. And this Book is sufficiently described in Mr Newtons Letters of Octob. 24 & Novem 8 1676, & the Quadratures there cited out of it are not to be attained without the Method in dispute. The constant fluxion of x Mr Newton denotes by wthwith a point above it; but the constant increment of or moment of x Mr Newton denotes not by but by o & still uses this Notation as convenient: Mr Leibnitz hath no Notation for fluxions, & therein his Method is defective. The Only Rule for finding wchwhich Mr Newton has given for finding first second third fourth & other differences fluxions is conteined in the first Propoosition of the Book of Quadratures & was pub is a very true one & was published with examples in the second Volume of the works of Dr Wallis before any other Rule for finding second third & fourth Differences came abroad. And the very words of the Proposition were set down in the Scholium upon the second Lemma of the second Book of Principles, & in Mr Newtons Letter of 24 Octob. 1676, as the foundation of the method of fluxions. And the inverse of this Rule is the first Rule in the Analysis per series numero terminorum infinitas demonstrated by the method communicated by Dr Barrow to Mr Collins in the Iuly 16969 & that Rule is d demonstrated by the method of fluxions in the end of that Analysis. And without this Rule the Series for Quadratures wchwhich break off & become finite when the Curve can be squared by a finite equation, & wchwhich are mentioned in the said Analysis, are not to be attained 4. In translating this Letter of 7. Iune 1713 into French & printing it in the Novelles Literairs Decem. 28 1715, we are told that the Author of this Letter was MrIohn Bernoulli, & to make this credible, the citation of the Eminent Mathematician is omitted in the body of the Letter. But For if Mr I. Bernoulli be the Eminent Mathematician there cited by the author of the Letter he cannot be the Author himself. And Mr I. Bernoulli in a Letter to Mr Newton hath positively declared that he was not the author thereof. And if he had been the author thereof he would not have said that the Eminent Mathematician charged Mr Newton with a false Rule. That MathematiciamMathematician ch noted only that there was an error in a lion the Scholium upon Solution of Prob. III Lib. II Princip. Philos. & suspected that it lay in second differences. Mr Newton Nicolas Bernoulli told Mr Newton that there was what his Vnkle had observed. Mr Newton upon examining the Solution found that the error lay in drawing the Tangent of the Arch GH from the wrong end of the arch, GH & corrected the error himself & told him that the corrections solution should be set right in yethe new edition of the Principles. The Tangents of the Arcs GH & HI are the first moments of the arcs areas arcs FG & FH & should have been drawn the same way with yethe motion of the body describing these the Curve FGHIK, whereas through in advertency the tangent of the Arc FG had been drawn backward through inadvertency from the point of contact the contrary way from the point of contact.. There is an error of greater consequence committed in second differences by Mr Leibniz in his Tentamen de motuum cœlestium causis, (sect 15.) which tho often o complained of is not yet set right, And his friends will not see clearly to pull motes out of other mens eyes till they have pulled the beam out of their own nor so much as acknowledged.

Mr Leibniz appealed from the Commercium Epistolicum to the judgment of the anonymous Author of this Letter: but Dr Wallis an older & abler Mathema-
5. Mr Nicholas Bernoulli told Mr Newton from in his Vnkles name in autumn 16 1712 that there was an error in the conclusion of the solution of Prob. III Lib. II Princip. Philsoph. Math. Mr wchwhich his he suspected to lye in second differences Mr Newton corrected the error himself, shewed him the correction & told him that the Solution Proposition should be reprinted in the E new Edition wchwhich was then coming abroad. The Tangents of the Arcs GH & HI are first moments of the Arcs FG & FH & should have been drawn the same way with the motion describing those arcs, whereas through inadvertency one of them had been drawn the contrary way, & this was occasioned the error in conclusion.
There is an error of much greater consequence committed in second Differences by Mr Leibnitz L . . . . z A.C. 1689 in his Tentamen de motuum cœlestium causis sect 15: which tho off often complained, of is not yet corrected nor so much as acknowledged. Nor doth it appear by any instance that Mr L . . . . z knew how to work in second differences before Mr Newtons Book of Principles came abroad: whereas by it plainly appears by Prop. XIV. Lib II Princip. that Mr Newton wnwhen he wrote that Book knew how to work in second differences wchwhich in demonstrating that Proposition he there he there he he there calls Differentia Momentorum & id est momentum differentiæ. And Mr Leibnitz himself in the Acta Eruditorum for Iu May 169 1700 has acknowledged that Mr N. was the first who shewed by as specimen made publick, that I he had the method of maxima & minima in infinitesimals, & there called it a method of the highest moment & largest greatest extent. And in the Analysis per series numero terminorūum infinitas communicated by Dr Barrow to Mr Collins in the year 1669 Mr Newton mentions that by that method of Analysis Curvarum areæ & longitudines &c id modo fiat) exacto et Geometrice determinantur. And how this done by the Method of F is explained in the first six Propositions of the Book of Quadratures. And without that Method it cannot be done.
And Mr Collins in a Letter to Mr Tho. Strode dated 26 Iuly 1672, & still extant in & printed frotm the Original in the Commercium Epistolicum; mentioning the Papers wchwhich wchwhich he had received from Dr Barrow in the Iuly 1669, subjoyns: Ex quibus [chartis] et alijs quæ olim ab autore cum Barrovio communicata fuerant, patet illam methodum a dicto Newtono aliquot annis antea excogitatam et modo universali applicatam fuisse: ita ut ejus ope in quavis Figura Curvilinea propostaproposita quæ una vel pluribus proprietatibus definitur, Quadratura vel Area dictæ figuræ, acc ACCVRATA si possibilis SI POSSIBILIS SIT, sin minus infinite vero propinqua; Evolutio vel longitudo lineæ curvæ, Centrum gravitatis Figuræ, Solida ejus rotatione genita, & eorum superficies: sine ulla radicum extractione [lege exterminatione] obtineri queant. Thus by the testimony of Dr Barrow & Mr Collins, as well as by that of Dr Wallis, Mr Newton had the method described in the first six Propositions of the Book of Quadratures, some years before Iuly 1669. And these three ancient & able Mathematicians knew what they wrote: but the author of the Letter of 13 Iune 1713 knew above mentioned, wrote only by conjecture. His words are Ejusque conjecturæ meæ primum validissimum indicium est &c. He accused Mr Newton of plagiary without any better proof then conjecture & therefore is guilty of calumny, even by the concession of Mr Leibnitz. See above pag in the end of his Letter of 9 April 1716 to M. Conti printed above pag
Mr Newton in the Introduction to the Book of Quadratures said that he invented the Method of fluxions gradually in the years 1665 & 1666. This Book was published in the year 1704 which was nothing more then what not so much as Dr Wallis had published in the Introduct Preface to the first Volume of his works 1695 & notified to Mr Leibnitz in a Letter to him dated 1 Decem. 1696 without being then contradicted without being then contradicted [as I understand by the Acta Eruditorum for 169. This Book was published by Mr Newton in the year 1704 & the next year in giving an Account of it Mr Leibnitz wr in the Acta Eruditorum for the month of pag Mr Leibnitz is called the Inventor of the Method & the improvement there of is ascribed to Mr Bernoullej & the Marquess de l'Hospital, & thence is inferred that Mr Newton always used fluxions instead of the Leibnitian Differences just as Honoratus Faber substituted the progress of motions for the indivisibles in the Acta Philosophical Transactions f A.C. 170 represented that Mr Leibnitz had the Method from Mr Newton. Mr Leibnitz] In the Acta Eruditorum for Iune 1696 an Account is given of the two first Volumes of the works of Dr Wallis, & notice is taken of what wisasis published in the Preface to themose two Volumes relating to this meethod, without denying what was there said or complaining of the DrDoctor for saying it. The Author of that Account s in relation to what is said in the Preface hasth only indeed these words. Cæterum ipse Newtonus non minus candore quam præclaris in rem Mathematicam meritis insignis, publice et privatim agnovit Leibnitium tum cum (inter veniente celeberrimo Viro Henrico Oldenburgo Bremensi Societatis Regiæ Anglicanæ tunc Secretario) inter ipsos (ejusdem jam tum Societatis Socios) commercium intercederet, id est, jam fere ante annos viginti et amplius, Calculum suum Differentialem, Seriesque Infinitas & pro ijs quoque Methodos generales habuisse; quod Wallisius in præfatione Operum factæ inter eos communicationis mentionem faciens, præterijt, quoniam deo eo fortasse non satis ipsi constabat. And upon these words there is this Observation in the Commercium Epistolicum. Methodum Differentialem Moutoni – – – – N . . . . s nondum agnovit publice. I add that I never did acknowledge it either publickly or privately. Mr L . . . z printed the published the Elements of his Method A.C. 1684 without making any mention of the correspondence he had formerly had with me. Mr N . . . . n demonstrated the Elements of this d Method of moments the next year in the second Lemma of yethe second book of Principles & added a Scholium not to give away this Lemma to Mr L . . . z but to assert it to himsel in a civil manner, M by putting him in mind of that correspondence & of making making that ackledgmentacknowledgment publickly wchwhich he made privately in his Letter of 13 Iune 21 1677 wherin he first began to communicate this Differential method, & acknowledg that Mr Newton's Method did the same things mentioned in his Letters of 13 Iune & 24 Octob 1676 as a part of a Treatis wrote by him in 1671, did the same things.
The Acta Eruditorum for Iune 16796 came to the hands of Doctorr Wallis in the end of November 171 following, & the DrDoctor in a letter wroiten th to Mr Leibnitz the next day Decem. 1st, has these words. Neque Calculi Differentialis vel Nomen audivisse me memini – – – – – id monitum inseruerim. Thus Mr Leibnitz had fresh notice of the Paragraph inserted into the said Preface of the two first Volumes of the DrsDoctors Works, & yet neither denied in the Letters wchwhich afterwards passed between them denied not what the DrDoctor had there p had there published nor exprest himself in the least affended at it, [but on the contrary in his Letter to Dr Wallis dated Mar. 1697 said De Te autem quæri mihi nunquam mihi in Mentem venit; quem facile apparet nostra in Actis Lipsiensibus prodita, non satis vidisse. He only took notice represented that that the DrDoctor had said but little about theis performances of Mr Leibnitz published in the Acta Eruditorum but& acquiesed in the DrsDoctors excuse who seldome read those Acta; but blamed not the DrDoctor for saing that Mr Newton in his Letters of Iune 13 Iune & 24 Octob. 1676 had explained to Mr Leibnitz the Method in dispute found by him ten years before or above.]
482
In autumn 16713 I received from Mr Chamberlain (who then kept a correspondence wthwith Mr Old Leibnitz) a flying Paper in Latin dated 29 Iuly 1713 in wchwhich it was pretended that Mr Leibnitz being then at Vienna had not then the Commercium Epistolicum nor had time to examin it himself but had referred it to the judgment of a very efamous Mathematician who was impartial & very able to judge of it, & had received his judgment in a the ther following a Letter of dated Iune 7th 1713,. as f Then And this Letter was inserted into the flying Paper, & in the end of the Letter Mr Iohn Bernoulli was cited by the author of the Letter as a Person different from himself, in these words [quem admodum ab enminente quodam Mathematico dudum notatum est. For these words referred to a Paper publisheed by Mr Iohn Bernoulli in the Acta Eruditorum of Feb. et Mar. 1713.
This flying Paper was print translated into French & inserted into nother Letter of the same stile of yethe former & printed inat the Hague in Holland in the Mr Iohnsons Iournal Literaire of Mr Iohnson A of Novem & Decem 1713 pag 448, 449, 450 & 451. And two years after it was printed again in Holland in the Novelles Litteraires & in this Impr for Decem. 28 1715 pag 414 & inthe sentence [quemadmodum ab eminente quodam Mathematico dudum notatū est] was now left out & the world was told that Mr Iohn Bernoulli was the the author of the aforesaid Letter of Iune 7 1713. [And the next year Mr Leibnitz in a Letter sent by written by himself Apr. 18. 17616 & sent by Madam Pelniz to Madam Kilmanseg, he intsertd the same translation of the Letter said Letter of Iune 7 1713 omitting the words [quemadmodum ab eminente quodam Mathematico dudm notatum est,] & affirming that Mr Bernoulli was the author of the Letter. And I have been told] And about two years after Mr Leibnitz began to father the said Letter upon Mr Bernoulli & for tht end to omitt the said citation in the copies of that Letter wchwhich he then sent to his friends. For
In November or December 17145 Mr Leibnitz he wrote a Letter to Senr Conti with a Postscript relating to me. And in the Postscript was this sentence. Il ne paroit point que M. Newton ait eu avant moi la Characteristique & l'Algorithm infinitesimasl, in which were these words suivant ce que M. Bernoulli a tres-bien jugé. [And thereby I knew that Mr Leibnitz was ascribed the L to Mr Iohn Bernoulli the aforesaid Letter of Iune 13 7 1713. But I doubted of it & in my Answer dated 26 Feb. 171 & I called that Letter the Answer of the Mathematicanian or pretended mathematician meaning dated Iune 7 1713: meaning the Answer of the Mathematician who either was & by the pwords pretended Mathematician I meant the Mathematician pretended to be the author of the said Letter. For because [the words [quemadmodum ab eminente quodam Mathematico dudum notatum est] were omitted in order to fit] the author of the Letter cited Mr Bernoulli as a man different from himself I doubted whether Mr Bernoulli was the true author or only the prendedpretended author of the Letter.]
And About the same time [that Mr Leibnitz sent the said Postscript to Senr Conti] he sent a letter with the tn aforesaid flying paper to the author of the Novelles Litterairs in Holland who printed it them both in that Collection Decem 28 1715 pag 414: & the sentence [quemadmodum ab eminente quodam Mathematico dudum notatum est] was now left out, & the world was told that Mr Iohn Bernoulli was the author of the aforsesaid Letter of 17 7 1713. And the next Spring soon after in in a Letter written by himself & Apr 18 1716 & sent by Madam Pelniz to Madam Kilmanseg he ascribed the same inserted a copy of the same Letter of Iune 17 1713 & ascribed it to Mr Bernoulli omitting the aforesaid sentence by wchwhich the Author of the Letter had distinguished himself from cited Mr Bernoulli as a man different from himself. And again in the Postscript of a Letter written about the same time to Count Bathmarke he affirmed that Mr Bernoulli was the author. [But I yet I doubted of this (for the reason above mentioned untill I received Mr Bernoulli's Letter5) of Iuly 5th, 17219 & by that Letter I became fully satisfied that Mr Bernoulli was not the Author, he therein asserting per omnia humanitatis sacra that he wrote no such Letter. The Author of the Letter inciting Mr Bernoulli as a person different from himself is one witness that Mr Bernoulli did not write that Letter. Mr Leibnits who sent that Letter to the Presse with that citation in it is another witness. And Mr Bernoulli is a third. [And he that falsified the Letter by striking out the citation in order to father it the Letter it upon Mr Leibnitz Bernoulli is a witness that it cannot be fathered upon him without a falsification] It cannot be fathered upon Mr Bernoulli without falsifying the Letter by striking out that citation.] And But these two last Letters were not printed not published till about two years after, & I had no hand in publishing them. The three or four first four or five f sheets of the second part of M. Desmaizeans collection (in wchwhich these letters are conteined, were printed off in Holland before I knew any thing of the designe to publish them.
About the time that those Letters went into the Press, Mr Des Maizeaus received from Ser Conti then at Paris several manuscript pieces of Mr Leibnit as he mentions in his Letter to Senr Abbe Conti dated 21 Aug. 1718, & printed in the said second part pag. 362, 363. saying that In that Letter he said that he would add themse pieces to the other writings of Mr Leibnitz wchwhich he was going to print in Holland. And you have them in the said second Part. Mr Des-Maizeaus had a correspondence with Mr Leibnitz & was his friend & on that account published this collection of his Remains.
About etlenven months after the writing of this Letter, when the Collection was almost printed off except the preface, I received from you Mr Bernoullis Letter dated Iulij 5. 1719 in wchwhich he assured me that he wrote no such Letter to Mr Leibnitz as that dated 7 Iune 1713, notwithstand & in my Answer I acquiesced in that Declaration notin & have ever since told my fsriends that I am satisfied that Mr Iohn Bernoulli was not the author of that Letter, [notwithstanding what Mr Leibnitz had written in the affirmative.] The author of the Letter in citing Mr I. Bernoulli as a person different from himself is one a witness that Mr I. Bernoulli was not the author thereof. Mr Leibnitz himself in sending that Letter to the Press both in Germany & in Holland with the in the year 1713 with that citation in it, is another witness that he then knew that Mr Iohn Bernoulli was not the author Mr Iohn Bernoulli in affirming per omnia humanitatis sacra that he wrote no such L anonymous Letter is a third withnes, & the leaving out that citation in order to father the Letter upon Mr I. Bernoulli is a falisification of the Letter. And for these reasons I have been & am still of opinion that Mr I. Bernoulli was not the author.Written in 1720
SrSir
The author of the Letter of Iune 7th 16713, as it was at the first sent to the Press by Mr Leibnitz, cited Mr Iohn Bernoulli as a person different from himself in these words [quemadmodum ab eminente quodam mathematico dudum notatum est.]
In the winter between the years 1715 & 1716 Mr Leibnitz began to father the said Letter upon Mr Leibnitz & for that end to leave out the citations abovementioned in the copies of it wchwhich he then sent to his friends: as I find by his Letter to Senr Conti writ in November or December 1715 where he hushas this expression suivant ce que M. Bernoulli a tres bien judge. & by his Letter sent at the same time to the author of the Novelles Litterairs in Holland & his Letter of Apr 18 16716 [in both wchwhich he inserted copies of the said Letter of 16 7 Iune 16] sent to Madam Kilmanseg & his Letter sent about the same time to Count Bothmar.

Observations upon the foregoing Letter.
a Here Mr Newton is directly accused of plagiary & the whole Letter tends to prove it.
1. In the second Lemma of yethe second Book of Principles the Elements of the Method of fluxions are taught, without with prict letters & in the Introduction to the Book of Quadratures the method it self is expresly taught & illustrated by examples & all this is done without the use of prickt Letters.
2 It is falsly alledged that in the Book of Principles there was frequent occasion of using the calculus of fluxions: for the book was written by the method of Composition.
3 The third Volume of Dr Wallis came abroad in Spring 1699 & Prickt letters appeared in the second Volume of the works of Dr Wallis wchwhich was almost all printed in the year 1692 & came abroad the next Spring before the Differential method began to make a noise. And the MS of D was in the hands of Dr Halley & Mr Raphson in the year 1691, & is sufficiently described in Mr Ns Letters of 24 Oct 1676 & Novem 8. 1676 & the Quadratures there cited out of it are not to compassed without the method of fluxions.
4 The first Proposition of the Book of Quadratures conteins the true method rule of finding the first second third & fourth fluxions &c and was published with examples in the second Volume of the works of Dr Wallis with examples i first & second fluxion & by consequence some years before any other rule for finding second & third & fourth differences came abroad.
5 The constant moment of x wchwhich I Mr Newton sometimes notes wcthwith x pointed Ihe still notes sometimes wthwith o & finds it advantageous
6 By the an Eminent Mathematician here cited the author of the Letter meant Mr Bernoulli somebody a Mathemation different from himself, and to nor could & Mr LeibnitLeibnitz could not take them for one & the same person when he first published this Letter. And therefore if Mr Iohn Bernoulli was the eminent Mathematician he was not the Author of the Letter, as he himself assures us that he was not This Letter was translated into French & reprinted in in French Decem. 1713 in the Iournal Literair Lib. II. Part II. pag 450 Anno Chr. 171 in Decem. 1713. And again in the Novelles Litterairs Decem 28 1715 pag 414. And in this last edition were are told that Mr Iohn Bernoulli was the Author of the Letter, & to make the Reader beleive this, the citation of the Eminent Mathemation is omitted in the body of the Letter as it is also in the same Letter inserted by Mr Leibnitz into his Letter to Madam Kilmansegg dated 18 Apr. 1716 & .See above pag. 37 [Mr Newton in his Letter of 26 Febr. 17616 printed above pag 17 called the Author of this Letter a Mathematician or pretended Mathematician & Mr Leibnitz in his Answer calls him dated 9 Apr. 1716 blames him for calling a Mathematician of the first rank a pretended Mathematician And Mr Newton in his Remarks dated 29 May S1716 St. n. replied that it was above two years before we told that after the writing of that Letter, before we were told that the was Mr Iohn B the Mathematician was Mr Iohn Bernoulli, & that he did not called him a Mathematician or pretended Mathematician, tnot to disparage his skill, but only to express his doubt whether Mr Iohn Bernoulli was really the author of that Letter or only pretended to be the Author thereof. And therefore what he said in the Papers printed above in relation to Mr I. Bernoulli'shis being the author of that Letter was only upon a supposition that he was the author. But it appears now by his Letters to Mr Newton that he was not the author: & therefore all that was said upon that supposition falls to the grownd & ought not in the least to reflect upon Mr Bernoulli For him] But on the contrary Mr Iohn Bernoully has told us solemnly that he was not the Author] Mr Leibnitz has done very ill therefore to omit this citation in order to father the the Letter upon Mr Iohn Bernoulli. For as it appliears by this citation that Mr I. Bernouly was not the Author so Mr I. Bernoulli has in a Letter to Mr Newton solemnly declared that he was not the Author. And since, no other author then Mr Leibnitz appears either of this Letter or of the Letter of the Letter of 29 Iuly 16713 into wchwhich this was inserted: Mr Leibnitz ought to pass for the Author of them both. For this last mentioned named Letter mentions what passed between Mr Leibnitz & Mr Hugens at Paris in the year 1675 wchwhich no body about 40 years before which no body in Germany knew besides Mr Leibnitz & therefore no body else could write the Letter; A & the word illaudabilis used in this Letter is peculiar to Mr Leibnitz. Had not the two Letters been feigned by Mr Leibnitz, but really written by other Authors of note, it would have been the interest of Mr Leibnitz to have named his Authors when he first published the Letters. And therefore since he did not name484 name his authors but endeavoured above two years after to father one of them upon Mr Bernoulli & ce & certainly wrote the other himself: its plain that he wrote them both himself & by consequence had the Commercium Epistolicum by him when he wrote them, but t found it unanswerable & therefore betook himself to the writing of Libels against i. pretended that he had not seen it nor had leasure to answer it, & betook himself to the writing of defamatory Libels against it.
6 By the eminent Mathematian here cited the Author of the Letter meant a Mathematician different from himself. And Mr Leibnitz could not take them for one & the same person when he first received this Letter & sent it to the Press. And therefore if Mr Iohn Bernoulli was this eminent Mathematician he was not the auther of the Letter. How ever in translating printing this Letter translated into French in the Novelles Literairs Decem 28, 1715, we are told that this the Author of this Letter was Mr Iohn Bernoulli, & to make this credible the citation of the Eminent Mathematician is omitted in the body of the Letter. But Mr Iohn Bernoulli in a Letter to Mr Newton hath positively declared that he was not the author thereof.
A Letter dated 7 Iune 16713 being mentioned above with some as written by Mr Iohn Bernoulli; to set that matter right we will here set down that Letter with the following Observations upon it.

Observations
1 See the Preface to Dr Wallis his the first Volume of the
1. Mr Newton is here accused of plagiary by a mere conjecture & the whole Letter tends to prove it make it probable contrary to the testimoney of an abler & older MathematianMathematician Dr Wallis in the Introduct Preface to the first Volume of his works.
2 In the second Lemma of the second Book of Principles the Elements of the secon Method of fluxions are taught, & in the Introduction to the book of Quadratures the Method it self is expresly taught & illustrated by examples, & all this is done without the use of prickt Letters.
3 In the Book of Principles there was not occasion of using the calculus of fluxions. For the book was writ by the Method of Composition.
4 The third Volume of the works of Dr Wallis came abroad in Spring 1699. And prickt letters appeared in the second Volume of his works wchwhich was almost all printed in the year 1692, & came abroad the next Spring before the Differential method began to make a noise. The Manuscript of the book of Quadratures was in the hands of Dr Halley & Mr Raphson in the year 1691 as both of them have attested And this book is sufficiently described in Mr Newtons Letters of Octob 24 & Novem 8. 1676, & the Quadratures there cited out of it are not to be compassed attained without the Method in dispute.
5. The first Proposition of the Book of Quadratures conteins the true Rule of finding first second third fourth & & other fluxions &c and was published with examples in the second Volume of the Works of Dr Wallis some years before any other Rule for finding second third & fourth differences came abroad. And the very words of the Rule were inserted set down in the sScholium upon the second Lemma of the second Book of Principles, & in Mr Newtons Letter of 24 Octob 1676, as the foundation of the Method of fluxions.
6 Mr Newton denotes fluxions by prickst letters & moments by fluents by any letters, their fluxions by the same letters with pricks set over them, & their moments by their fluxions multiplieed by the letter o & its powers . And where he puts the letter o for the constant moment of x he puts an unite for that is for the constant fluxion of x, & still uses this notation as very advantageous. Mr Leibnitz hath no notation for fluxions, wchwhich is a defect in his to denote the the moments of fluents (wchwhich he calls their differences) præfixes d, dd, , &c to the fluent but has no notation for their fluents, w fluxions; wchwhich is a defect in his method.
7 By the eminent Mathematician here cited, the Author of the Letter meant a Mathematician different from himself. And Mr Leibnitz could not take them for one & the same person when he first received this Letter & sent it to the Press. And therefore if Mr Iohn Bernoulli was the Author of this Letter he could not be eminent Mathematician, he was not the author of the Letter. However, in printing this Letter translated into French, in the Novelles Literaires Decem 28 1715, we are told that the Author of this Letter was Mr Iohn Bernoulli, & to make this credible, the citation of the eminent Mathematician is omitted in the body of the Letter. But Mr Iohn Bernoulli is a Letter to Mr Newton hath positively declared that he was not the author thereof.

Observations upon the foregoing Letter
1. The author of the Letter asc citeds Mr Iohn Bernoulli as a person different from himself, & doth it with an Elogium by the title of a certain Eminent Mathematician, & thereby denyed that Mr Iohn Bernoulli was the Author.
2 Two years & an half after the publishing of this Letter it was translated into F a translation of it into French was published in Holland the Novelles Literaires in Holland & the there (as also in a Letter otfo Mr Leibtz to Madam Kilmansegg) this Letter was ascribed to Mr Iohn Bernoulli & to make this credible the aforesaid citation was omitted. Whereas if Mr And M And the same three And Mr Leibnz in 3 Mr Iohn Bernoulli d not but know that that the first a Letter to Madam Kilmangseg has Which act of omitting it is not justifiable but savours of falsification & this
3 Mr Iohn Bernoulli could not but know that in the book of Mathematical Principles the Elements of the Method of fluxions were set down without the use of prickt Letters in the second Lemma of the second book of math. Principles of Philos., & that there was no occasion to use prickt Letters in that book because it was written by the method of Composition, & that the true first Proposition of the Book of Quadratures was priublished with prickt letters in the second Volume of the secon works of Dr Wallis wchwhich came abroad in Spring 1693 before at wchwhich time at wchwhich time the Differential Method was only beganining to be talked of in England make a noise As that that theis Proposition conteins the true Rule of finding first second third fourth &c differences other fluxions & was there illustrated with examples in first & second dfluxions & & that this was the first Rule made publick for this purpose. And for these reasons he could not finding second & third differences. And all this makes it highly improbable that Mr Bernoulli could should be the author of the said Letter.
4 Mr Iohn Bernoulli has in a letter written Mr Iohn Newton 5 Iuly N. S. 1719 hath decleared that he was not the Author of the said Letter. His words are.
About half a year after the publication of the Commercium Epistolicum Mr Leibnitz it was pretended In a flying paper dated 29 Iuly 1713 it was pretended that he the Leibnitz had not seen the book but hearing th had written to an eminent a MathematianMathematician of the first rank, who very skilfull in these matters who upon examining all things had given his opinion of the matter in the follo in a Letter dated 7 Iune 1693 as follows.
Videtur N . . . . s — postquam alijs fuisset familiaris.
Vpon this
This Letter therefore conteins the judgment of an eminent Math or pretended judgment of a Mathematician or pre to whom Mr Leibnitz appealed from the judgment report of the Committee of the R. S. It was printed in Germany without the name of the author or printer or Mathematician or city where it was printed & it was dispersed over Europe two years & an half before we were told who was the author that Mr Iohn Bernoulli was the author of it. This were told in This That he was the Author we were told in the Novelles Literairs for the month of 1716 & afterwards isn some Letters of Mr L. to md & to make it probable, the citation of Mr Iohn Bernoulli in the body of the by wthwith an Elogium in yethe body of the Letter was omitted. But
But in that citatio we have the testimony of the author of the Letter that Mr Iohn Bernoulli was a person different from himself. not the author. And The omission of the citation cannot he justified. It amounts to a falsification of the Letter for suppressing theis evidence that testimony of the author of the Letter that Mr Iohn Bernoullei was not the author thereof.
Mr Iohn Bernoulli could not but know — — — be yethe author of the said Letter.
Mr Iohn Bernoulli in a letter — — — his words are — And so we have two witnesses the author the Letter & Mr Iohn Bernoulli that Mr Iohn Bernoulli was not the author.
The Letter therefore is of no credit the Author of it being still unknown.
