here cited out of the Preface to the two firft Volumes of 
Dr. Wallis’s. Works, it appears that Mr. Leibnitz, had 
feen that Part or the Preface, where Mr. Newton is find 
\ to have explained to him (in the Year 1676) the Method of 
Fluxions found by him Ten Years before or above. 
Mr. Newton never allowed that Mr. Leibnitz had the Dif- 
ferential Method before the Year 1677. And Mr Leibnitz 
himfelf in the Acta "Eriiditorum for April 1691. pag. 178. ac- 
knowledged that he found it after he returned home from 
Paris to enter upon Bufmefs, that is, after the Year 1676. 
And as for his pretended general Method of infinite Series, 
it is lo far from being general, that -it is of little or no ufe. 
I do not know that any other Ufe hath been made of it, than 
to colour over the Pretence of Mr. Leibnitz to the Series of 
Mr. Gregory for fquaring the Circle. 
Nit- Leibnitz, in his Anfwer' to Mr* Fatio printed in the 
Acta Eruditorum for the Year 1700. pag. 203. wrote thus.
