‎First printing of South's second large star catalogue of the distances and positions of double and triple stars.""Double stars, essentially discovered by Wiiliam Herschel, were of great interest throughout the nineteenth century—new ones being found and position measurements made more precise with each improvement in telescope construction. South, working with John Herschel during the years 1821–1823. reobserved the double stars charted originally by William Herschel, mainly for the purpose of detecting position changes. Their observations helped verify the newly recognized orbital motion of these neighboring stars. Their resulting catalog of 380 double stars, presented to the Royal Society in 1824, earned them the gold medal of the Astronomical Society and the grand prize of the Institut de France. For his second catalog of double stars, two years later, South was awarded the Copley Medal of the Royal Society.""(DSB).‎
