| Title | Burrard, Sir Sidney Gerald: certificate of election to the Royal Society |
| Citation | Superintendent of the Trigonometrical Survey of India. He has been connected with the Survey of India since 1883. He determined sixteen telegraphic longitudes in 1886-1887-1888, and in 1889 he discovered the cause of circuit errors in the determination of longitudes (see Gen Walker in 'Phil Trans,' Series A, vol clxxxvi, pt II, 1895). In 1890-1894 he was employed in determining astronomical latitudes and deflections in the plains of India, and pointed out in a report to Government that the deflections were systematic, and not merely local. In 1895-1896, in conjunction with Capt Lenox-Conyngham, he was employed in finding the Greenwich-Madras longitude 'via' Teheran. The details of these operations are contained in a report of 1896. In 1897-1898 he opened tidal stations in the Red Sea. In 1898 he found the latitude of Madras. In 1899 he succeeded Col Gore as Superintendent of the Trigonometrical Survey. He was the author of a series of Professional Papers in 1900-1902, in which he showed that the theories of Pratt and Walker, in explanation of the anomalies of gravity in the sub-Himalayan regions, were inadequate. Author of a paper on 'The Attraction of the Himalaya Mountains upon the Plumb-Line in India' (Monthly Notices, Royal Astronomical Society, vol lxii, 1902). In charge of the new series of Indian observations with the half-second pendulum, and for this end worked at Potsdam in the autumn of 1902. |
