1677 ? ho ocher Proof befides the Conceffion of Mr. Nefrtdh 
that he had it fo early ; affirmed not that he had it earlier ; 
commended Mr. Newton for his Candour in this Mat® 
ter; allowed that the Methods agreed in the main, and 
Paid that he therefore ufed to call them by the common Name 
of his bfinittfimd Andyfis ; reprefented, that as the Me- 
thods of V'teta and Cartes were called by the common 
Name of Analjfis Sped of a, and yet differed in fome things; 
fo perhaps the Methods of Mr Newton and himfelf mighc 
differ in fome things, and challenged to himfelf only thofe 
things wherein, as he conceived, they mighc differ, naming 
the Notation, the differential Equations and the Exponential 
Equations. Butin his Letter of Jane 2 1.1677 he reckon’d diffe- 
rential Equations common to Mr. Newton and himfelf. 
This was the State of the Difpute between Dr. Wallis and 
Mr Leibnitz, at that time And Four years after, when 
Mr. Fatio fuggefted that Mr. Leibnitz., the fecotid Inventor of 
this Calculus, might borrow fomething from Mr. Newton, the 
oldefl: Inventor by many Years: Mr. Leibnitz in his Anfwer, 
publifhed in the Acta Eruditorum of May 1 700, allowed that 
Mr. Newton had found the Method apart, and did not deny 
that Mr, Newton was the oldefl: Inventor by many Years, nor 
afferted any thing more to himfelf, than that he alfo hacE 
found the Method apart, or without the Afliftancc of 
Mr. Newton , and pretended that when he firfh publifhed it, he- 
knew not that Mr. Newton had found any thing more of it- 
than the Method of Tangents. And in making this Defence 
he added : Quam [methoduml ante Domimim Newtonum & Me* 
nulius quod fciam Geometra babnit ; uti ante kune maximi nominis 
Geometram N E M 0 jpecimine pub l ice dato fe habere probavit, ante 
Dominos Bernoullios & Me nnllus communicavit. Hitherto there® 
fore Mr. Leibnitz did not pretend to be the ffrft Inventor. He 
did not begin to put in lueh a Claim till after the Death of 
Dr. Wallis, the laft of the old Men who were acquainted with- 
what had pafled between the Englijh and Mr. Leibnitz
