Title: An account of the discoveries concerning comets, with the way to find their orbits, and some improvements in constructing and calculating their places. For which reason are here added new tables, fitted to those purposes; particularly with regard to that Comet which is soon expected to return Author: Barker, Thomas Place: London Publisher: Printed for J Whiston and B. White Date: 1757 Description: [6], 52, [2] pp. Folding engraved plate. (4to) 22.5x17.5 cm (8¾x6¾"), modern boards, new endpapers. First Edition. The author's principal work, containing a catalogue of the elements of the comets then known, and an explanation of Newton's problem of finding a comet's orbit from three observations. The most valuable (and most original) part is the "Table of the Parabola," for ascertaining any orbits which are approximately parabolic. The work is quite scarce: only two copies have sold at auction since 1975, according to American Book Prices Current. Lot Amendments Condition: Soiling to boards; title-page fore-edge with a touch of wear, plate with slight loss along a fold; very good. Item number: 287915
