J. On the Early History of Infiniteshnuls in Enfjland. 

 By Professor De Morgan*. 



[EFORE stating the subject of this pa])er, I make the fol- 

 ' lowing addition to what appeared in June last, in proof 

 ot Newton having written the account of the Commerc. Epist. in 

 Phil. Pram. No. 312. I there considered Pemberton as a wit- 

 ness, because, for reasons given, I coukl not imagine how Dr. 

 V\ ilson coukl have neglected to notice his dissent, if indeed lie 

 had dissented : I considered that Pemberton had allowed Wilson, 

 in 1761, to affirm Newton^s authorship. I have since found 

 that Pemberton also, and perhaps more distinctly, allowed Robins, 

 in 1735, to make the same affirmation. In the Present State of 

 the Republic of Letters for 1735 and 1736, and the Works of the 

 Learned hi' 1737, will be found more than twenty articles of the 

 Analyst^ controversy, between Robins, at first anonymous, 



* Communicated by the Author. 



t The most complete Hst I can give of the jjieces of this coutroversv 

 may be made thus. To the twenty-six articles headed AMnlj/st Controversy 

 in the cataloirue of the Astrouomical Societ3''s library (1850) add the fol-
