to the world that he was the first inventor thereof. But for the future {illeg} {illeg} when ever he represents himself the first inventor of exponential equations he ought at the same time to acknowledge that Mr Newton gave him light into the invention by teaching him the use of dignities whose indices were fract surd {illeg}|or| indeterminate. [And whereas he pretends to have enlarged Geometry by Exponential Equations he ought to consider that the indices of all dignities are numbers & where the numbers are fluents, the æquations are Arithmetical & have no place in Geometry. Geometrical quantities may be represented by numbers but are not numbers & Arithmetic may be applyed to the resolution of Geometrical Problems: but such resolutions are only Arithmetical, & have no place in Geometry untill they are demonstrated by Geometrical Proposition & thereby become Geometrical Solutions. Nothing is legally admitted into Geometry \Geometry is composed of nothing else then/ except \besides/ Definitions Axioms Lemmas & Propositions \Lemmas & Corollaries/ demonstrated synthetically, And Analysis is noth whether ancient or modern is only \only/ a mean of resolving Problemes: {illeg} \and/ the Resolutions ought to be turned into Geometrical Solutions by Compos \Geometrical/ Synthesis or Composition before the Problem Propositions be admitted into Geometry.]

Mr Ne Sr M|I|. Newton in his Letter of 24 Octob. 1676 wrote that he had two methods of resolving Invers Problemes of tangents & such like difficult ones, one of wch \methods/ consisted in assuming a Series for any unknown quantity from wch the other unknown quantities might easily be conveniently be deduced & in the collection of the homologous terms of the resulting equation, for determining the terms of the assumed series. Mr Leibnitz has \s{illeg}|o|me years after/ published this method as his own claiming to himself the first invention thereof. If remains that he either renounce this claim publickly \& acknowledg that M|S|r I. Newton was the first Innovator/ or prove that he invented it before 24 Octob. 1676 Sr M|I|. Newton wrote the said Letter.

And this was the top of his skill when he wrote his Letter of 27 Aug. 1676. For in that Letter he said of one part of this Method: Nihil est quod norim in tota Analysi momenti majoris. And of another part: Cujus vim ac potestatem nescio an quisquā hactenus sic consecutus. Ea vero nihil differt ab Analysi illa suprema ad {illeg} cujus intima Cartesius non pervenit.
