CitationLate President of Roy Meteorol Soc, Superintendent of the Magnetical and Meteorological Department, Royal Observatory, Greenwich. Connected with the Royal Observatory since 1841, and since 1875 has been Superintendent of the Magnetical and Meteorological Department. For eighteen years previously, in addition to astronomical work, had charge of the Chronometer and Time Signal Department. First showed how completely the long series of Greenwich magnetic observations confirmed the existence of sympathetic variation between solar spots and terrestrial magnetism, for horizontal force as well as for declination. Among other works, carried out, on the English side, the whole of the operations in the telegraphic determination of the longitude of Cairo, in which a submarine line of about 3000 miles in length was used in an unbroken circuit. His discussion of these operations is given in the British 'Account of the Observations of the Transit of Venus, 1874.' Applied the principle of the galvanic regulation of clocks to the regulation of a chronometer. Was formerly Observer in Durham University Observatory, his astronomical work during this time being published in the Astronomische Nachrichten, vols xxxv, xxxvi, and xxxvii. Is the author of a paper in the Phil Trans 'On the Relation between the Diurnal Range of Magnetic Declination and Horizontal Force, as observed at the Royal Observatory, Greenwich, 1841 to 1877, and the Period of Solar Spot Frequency.' Also of papers in the 'Memoirs' and 'Monthly Notices' of the Roy Astron Soc, the Quart Journ Meteorol Soc,' and other scientific journals.
