Autograph letter to Roger Cotes

Draft of letter for which the final version does not survive, of late Jul./early Aug. 1712, containing a draft of the Scholium to Proposition 35 of the Principia, 2nd ed., 1713. See A.R. Hall and L. Tilling (eds.) The correspondence of Isaac Newton. Vol. 5, 1709-1713. CUP, 1975. pp 315-319, letters 929 and 931.

The letter was discovered in JCA's papers with letters from D. Brewster, March - May 1855, (Box 5/37), and had evidently been sent to Brewster for comment and returned, through the post.

The remainder of Newton's drafts of letters to Cotes are among the Portsmouth Papers in CUL, and the final versions (other than that of this letter), are in Trinity College Library.
