On reverse of Mint 19/2/340: draft relating to the calculus controversy. Mint 19/2/353 is followed by three variant draft attacks on Leibniz [preparatives for the letter printed in NC, 6: 80-95: see especially ibid., n. 54].

And indeed its impo to say that Mr Newton then understood not second fluxions is all one as to say theat he understood not how to consider motion or as a quantity increasing & decreasing.

11. In the last coinage of Copper money an hundred per an̄ for six year together made a great [clamour aming the people & & a] complaint in Parliament whereby the coynage was stopt for a year by reason of twotoo great a quantity of copper money & after yethe coynage of another hundred Tunns the nation was fully stockt for yethe next five or six years. So that six or seven hundred Tunns is abundantly sufficient to stock the nation & a coynage of 1500 Tunns in five years time is not practicable by reason of the clamours it would make among the people. At present there wants not above a 100 Tuns in all to supply what's wanting.

32. Copper of 10d per £wt is too coarse. T And there is no assay proposed by wchwhich the goodnes of the Copper may be known. A specimen is not sufficient.

43. The casting drawing cutting flatting Scouring nealing blanching & dying cannot be performed for 25£ per Tonn. And there is nothing set down for the Graver & Smith. The Patentees in the last coynage paid 3 pr lwt for making the blanks & Mr Neale

54. Eleven pounds per Tonn for putting away is too much

65. If the Copper be so coarse & the There is nothing set down for providing coyning Tools

76. If the copper should be so coarse & the coynage so cheap & 1500 Tonns be coined as pound weight sho b in the proposal a pound weight cannot should not be cut into above 15d or at most 1512 20d. TBut 7the money Should be coyned as neare as can be conveniently to the intrinsic value.

27. If a pound weight be cut into 20d, a Tonn in coyn will amount only to 186£. 123. 4. 7It must be cut into 21d that a Tonn may make 205. 6. 8.

The proper assay for Copper is by the ham hammering it when red hot & bending it when cold & observing the grain in breaking as at yethe is done at the Copper Mills. 99. The money of Denmark is made of Copper flatted at the battering Mills My LdLord Treasurer is desirous to have the money of fine copper, & if be of the same cfineness with the Copper money of Sweden, itthe must Copper must be made into filleths at yethe Battering Mills. For Copper of that degree of fineness will not cast be manufactured without casting. by casting. 340

T And whereas the great Mathematician represents that Mr Newton uses the letter o in the vulgar manner wchwhich destroys the advantages of the Differential method: he uses it & has used it ever since the writing of his Analysis in such a manner as makes his method more beautiful more & geometrical & more advanatageous then the differential & (by joyning the methods of Series & fluxions together) makes his method much more universal. then the differential. The Differential Method is nothing else then the method of Tangents & published improved by Mr Gregory & Dr Barrow by Mr in the year 16768 & by Dr. Barrow in yethe year 1670, disguised by changing the LettersDr Barrows symbols a & e into dy & dx, & improved by the instructions wchwhich Mr Leibnitz received Fro by the Letters of Mr Newton, assumed by from th& taken from them by pretending that heMr L. found it long before he d.Iid .

And thus much in answer to the great Mathematician
