FIRST EDITION of the second translation into English of the Principia, although only the first volume was published. Thorp’s translation, “though based on Motte’s edition of 1729, is considered by Cohen (Newton, 1969, p. iv) to be ‘notably improved and amended’. Further, he declared, for anyone wishing to follow Newton’s reasoning and ‘to comprehend this great treatise on its own terms, there is no better work…available in English’.” (Gjertsen, The Newton Handbook). This first edition is quite rare; it was reissued in 1802. Thorp was one of the three editors of the Excerpta published in 1765. Wallis 28. Gray 28. Not in Babson.
