SMYTH, See also:CHARLES PIAllI (1819-1900), See also:British astronomer, was See also:born at See also:Naples on the 3rd of See also:January 1819. He was called Piazzi after his godfather, the See also:Italian astronomer of that name, whose acquaintance his See also:father, See also:Admiral Smyth, had made at See also:Palermo when on the Mediterranean station. His father subsequently settled at See also:Bedford and equipped there an See also:observatory, at which Piazzi Smyth received his first lessons in See also:astronomy, At the See also:age of sixteen he went out as assistant to See also:Sir See also:Thomas Maclear at the Cape of See also:Good See also:Hope, where he observed See also:Halley's See also:comet and the See also:great comet of 1843, and took an active See also:part in the verification and See also:extension of La Caille's arc of the See also:meridian. In 1845 he was appointed astronomer royal for See also:Scotland and See also:professor of astronomy in the university of See also:Edinburgh. Here he completed the reduction, and continued the See also:series, of the observations made by his predecessor, Thomas See also:Henderson (see Edinburgh Observations, vols. xi.-xv.). In 1856 he made experimental observations on the See also:Peak of See also:Teneriffe with a view to testing the astronomical advantages of a See also:mountain station. The See also:Admiralty made him a See also:grant of £500 for the purpose, and a yacht—the " Titania "—of 140 tons and a See also:fine 72 in. See also:equatorial See also:telescope were placed at his disposal by See also:friends. The upshot of the expedition was to verify See also:Newton's surmise, that a " most serene and quiet See also:air . . . may perhaps be found on the tops of the highest mountains above the grosser clouds." The scientific results were detailed in a See also:Report addressed to the lords commissioners of the admiralty, 1858, in a communication to the Royal Society (Phil. Trans. cxlviii. 465) and in the Edinburgh Observations, vol. xii. A popular See also:account of the voyage is contained in Teneriffe, an Astronomer's Experiment, 1858.

In 1871–1872 Piazzi Smyth investigated the spectra of the See also:

aurora, and zodiacal See also:light. He recommended the use of the " rainband for See also:weather prediction (Jour. Scottish See also:Meteor. Society, v. 84), and discovered, in See also:conjunction with Professor A. S. See also:Herschel, the See also:harmonic relation between the rays emitted by See also:carbon monoxide. In 1877-1878 he constructed at See also:Lisbon a See also:map of the See also:solar-spectrum (Edin. Phil. Trans. See also:xxix. 285), for which he received the Macdougall-See also:Brisbane See also:prize in 1880. Further spectroscopic researches were carried out by him at See also:Madeira in 188o (Madeira Spectroscopic, 1882), and at See also:Winchester in 1884 (Edin.

Phil. Trans. vol. xxxii. pt. ii.). He published besides Three Cities in See also:

Russia, (1862), Our See also:Inheritance in the Great See also:Pyramid (1864), See also:Life and See also:Work at the Great Pyramid (1867), and a See also:volume On the Antiquity of Intellectual See also:Man (1868). In 1888 he resigned his See also:official position and retired to the neighbourhood of See also:Ripon, where he died on the 21st of See also:February 1900. See See also:Month. Notices See also:Roy.
