, and procured for the purpose by Sir Isaac Newton. The inconveniences of this instrument were commented upon by Joseph Crosthwait. Pound's observations with it of the five known satellites of Saturn enabled Halley to correct their movements; and Newton employed, in the third edition of the Principia, his micrometrical measures of Jupiter's disc, of Saturn's disc and ring, and of the elongations of their satellites; and obtained from him data for correcting the places of the comet of 1680. Laplace also used Pound's observations of Jupiter's satellites for the determination of the planet's mass; and Pound himself compiled in 1719 a set of tables for the first satellite, into which he introduced an equation for the transmission of light.
