HERSCHEL, William (1738-1822). "Account of a Comet." Extract from: Philosophical Transactions 71. [London: W. Bulmer for W. Nicol, 1781].
4o, pp. 492-501. 3 folding plates. (Some minor browning.) 20th century calf-backed marbled boards (very minor fading).
FIRST EDITION, journal issue. In August 1781, Herschel observed through his telescope something other than a fixed star.
