    Description
    Letter from James Gregory [Gregorie] at St Andrews to John Collins, concerning a problem proposed to Isaac Barrow, 5 September 1670.

    This volume contains the letters and papers of John Collins (1625-1683), which came into the possession of William Jones (1675-1749), who used them in Commercium Epistolicum, designed to prove Isaac Newton’s priority over Gottfried Wilhelm Leibniz in the invention of fluxions (calculus).

    The original letters were sealed up at the order of the Royal Society's council (25 October 1714) and stored in an iron chest. Further letters used in the 1722 edition of Commercium Epistolicum must have been added and stored with the original papers. These were ordered on 13 September 1737 to be ‘taken out of the Iron Chest’ and entrusted to Jones, who was asked to paste them into a guard-book in one volume (CMO/2/252, CMO/3/73).
