a survey of recent algebra improvements made in England, and A Solution of a Chorographical Problem; while a letter written to John Wallis, 3 October 1682, was imparted to the society 20 May 1684. This was designed as preliminary to a formal treatise on algebra, never written. He helped forward many important publications. To him was due the printing of Isaac Barrow's Optical and Geometrical Lectures, as well as of his editions of Apollonius and Archimedes; of John Kersey's Algebra, Thomas Branker's translation of Rhonius's Algebra, and Wallis's History of Algebra. He took an active part in seeing Jeremiah Horrocks's Astronomical Remains through the press. Legacy About twenty-five years after Collins's death his books and papers came into the possession of William Jones, F.R.S. They included a voluminous correspondence with Newton, Leibniz, Gregory, Barrow, John Flamsteed, Wallis, Slusius, and others. From it was selected and published in 1712, by order of the Royal Society, the Commercium Epistolicum, of material relevant to Newton's priority over Leibniz in the discovery of the infinitesimal calculus; specimens of results from the use of the fluxional method were transmitted 20 July 1669 through Barrow to Collins, and by him made widely known.
