Aberdeen′, a university city and royal, municipal, and parliamentary burgh of Scotland, capital of the county of same name, mainly on the north bank of the Dee at its entrance into the North Sea, and between this river and the Don, with a part also on the south bank of the Dee, while the municipal limits include the adjacent Woodside. The site is in places somewhat hilly. Aberdeen is one of the oldest towns in Scotland, and was constituted a royal burgh by William the Lion in 1179. The streets are generally spacious and regular, the houses built of fine grayish-white granite. There are many handsome public buildings, as the County and Municipal Buildings, Marischal College, Grammar School, Infirmary, Arts School, Art Gallery, Music Hall Buildings, public library, &c. The finest street, Union Street, made in 1800, is carried over a valley by a granite bridge having an arch of 132 feet span. The small portion of the city called Old Aberdeen, long a separate town, consists mainly of a single street, stretching northwards to the River Don. Its chief buildings are King's College and St. Machar's Cathedral. Noteworthy features of the college buildings are the crown-tower and the chapel, the latter containing some very fine old carved woodwork. The cathedral, now used as a parish church, was commenced about 1357. There are several bridges over the Dee and Don. Over the latter is a fine old bridge (Brig o' Balgownie) of one arch, erected according to some accounts by Robert Bruce. There are docks 34 acres in area, an extensive tidal harbour and basin, and a graving-dock. The shipping trade is extensive. The industries embrace wool, jute, linen, combs, soap, preserved provisions, chemicals, paper, shipbuilding, engineering, and especially the cutting and polishing of granite. The fishing industry is of great importance. The city of Aberdeen returns two members to Parliament. Pop. 158,969.—The County of Aberdeen forms the north-eastern portion of Scotland, and is bounded on the east and north by the North Sea. Area, 1,261,521 acres. It is divided into six districts (Mar, Formartine, Buchan, Alford, Garioch, and Strathbogie), and is generally hilly, there being in the south-west some of the highest mountains in Scotland, as Ben Macdhui (4295 feet), Cairntoul (4245), Cairngorm (4090), Lochnagar, &c. Its most valuable mineral is granite, large quantities of which are exported. The principal rivers are the Dee and the Don, both of which enter the sea at the town of Aberdeen. Cereals (except wheat) and other crops succeed well, and the number of acres under cultivation is nearly double that of any other Scottish county. Great numbers of cattle are fattened and sent to London and the south. On the banks of the upper Dee is situated Balmoral, a favourite residence of Queen Victoria. Aberdeenshire and Kincardine unite in sending three members to Parliament. Pop. 300,980.—Aberdeen University, as now constituted, derives its origin from two different foundations; one, the University and King's College (Old Aberdeen), founded in 1494 by Bishop Elphinstone (who was bishop of Aberdeen from 1483-1514) under the authority of a papal bull obtained at the instance of James IV; the other, Marischal College and University (New Aberdeen), founded in 1593 by Geo. Keith, Earl Marischal, by a charter ratified by act of Parliament. The two foundations existed as separate universities, both having the right of conferring degrees, till 1860, when they were united and incorporated into one university, the University of Aberdeen. Holding the funds of both colleges and dating as from the foundation of King's College in 1494, the university has about 300 bursaries or exhibitions, mostly open to public competition, and a number of money prizes and scholarships. The classes for arts and divinity are held in King's College, and those for law and medicine in Marischal College. There is a full teaching staff in the faculties of arts, medicine, science, and divinity, and two professors in that of law. There are in all 25 professors and some 900 matriculated students. The constitution of the university is similar to that of Edinburgh and the other Scottish universities. The library contains over 80,000 volumes. The university unites with those of Edinburgh, Glasgow, and St. Andrews in sending three members to Parliament.
Aberdeen′, George Hamilton Gordon, Earl of, British statesman, born 28th Jan., 1784, died 14th Dec., 1860. He began his diplomatic life in 1801 as attaché to Lord Cornwallis's embassy to France, which resulted in the signing of the treaty of Amiens. In 1806 he entered Parliament as a Scottish representative peer, and in 1813 was entrusted with a successful mission to Austria for the purpose of inducing the emperor to join the coalition of sovereigns against Bonaparte. In 1814 he was created a British peer, and in 1828 he became foreign secretary in the Duke of Wellington's administration. During the short premiership of Sir Robert Peel in 1834-5 he acted as colonial secretary, and when Sir Robert again became premier in 1841 he took office as Secretary for Foreign Affairs. He was a warm supporter of
Catholic Emancipation, and endeavoured, though without result, to bring in a compromise bill in 1846, during the struggle which divided the Established Church of Scotland. Quitting office with his chief in 1846, he came, on the death of Peel in 1850, to be regarded as the leader of the Conservative free-trade party. On the Derby ministry failing to maintain its place, Lord Aberdeen returned to office in the end of 1852 as head of a coalition ministry. The principal event which marked his administration was the Crimean war; but the bad management of this irritated the country, and the ministry resigned in 1855. This event marks the close of Lord Aberdeen's public career. From his travels and his acquaintance with Greece and its antiquities he was called by Byron "the travelled thane, Athenian Aberdeen".

Aberra′tion, in astronomy, the difference between the true and the observed position of a heavenly body, the result of the combined effect of the motion of light and the motion of the eye of the observer caused by the annual or diurnal motion of the earth; or of the motion of light and that of the body from which the light proceeds. When the auxiliary cause is the annual revolution of the earth round the sun it is called annual aberration, in consequence of which a fixed star may appear as much as 20.4" from its true position; when the auxiliary cause is the diurnal rotation of the earth on its axis it is called diurnal aberration, which amounts at the greatest to 0.3"; and when the auxiliary cause is the motion of the body from which the light proceeds it is called planetary aberration.
