Educated at King's College School, the Charterhouse, and Trinity College, Cambridge, he was called to the bar in 1868, and made Q.C. in 1878. He was Member of Parliament for Launceston for a short time in 1885, and from that year to 1900 represented the Isle of Wight. He was Attorney-General from 1885-6, 1886-92, and 1895-1900, being then made Lord Chief Justice and elevated to the peerage: he had been created a baronet in 1899. He represented Britain in the arbitration with the United States regarding the Behring Sea (1893), in the affair of the Venezuelan and Guiana boundary (1898-9), and was one of three British commissioners who, with three from the United States, settled the Canada and Alaska boundary in 1903.

Alwar (al-war′), a State of north-western Hindustan, in Rajputana; area, 3141 sq. miles; surface generally elevated and rugged, and much of it of an arid description, though water is generally found on the plains by digging a little beneath the surface, and the means of irrigation being thus provided, the soil, though sandy, is highly productive. This semi-independent State has as its ruler a rajah with a revenue of £232,000; military force, about 5000 infantry and 2000 cavalry. Pop. 791,688.—Alwar, the capital, is situated at the base of a rocky hill crowned by a fort, 80 miles S.S.W. of Delhi. It is surrounded by a moat and rampart, and is poorly built, but has fine surroundings; it contains the rajah's palace and a few other good buildings. Pop. 41,305.

Amade′us, the name of several counts of Savoy. The first was the son of Humbert I, and succeeded him in 1048, dying about 1078; others who have occupied an important place in history are the following:—Amadeus V, 'the Great', succeeded in 1285; gained great honour in defending Rhodes against the Turks; increased his possessions by marriage and war; was made a prince of the empire; died in 1323.—Amadeus VIII succeeded his father, Amadeus VII, in 1391, and had his title raised to that of duke by the Emperor Sigismund. He was chosen regent of Piedmont; but after this elevation retired from his throne and family into a religious house. He now aspired to the papacy, and was chosen by the Council of Basel (1439), becoming Pope, or rather anti-Pope, under the name of Felix V, though he had never taken holy orders. He was recognized as Pope by only a few princes, and resigned in 1449, being the last of the anti-Popes. He died in 1451.

Amade′us, Duke of Aosta, for a short time King of Spain, second son of Victor Emanuel of Italy, and brother of Humbert I, King of Italy. He was born in 1845, and, thanks to the influence of Marshals Prim and Serrano, was chosen by the Cortes King of Spain in 1870, Queen Isabella having had to leave the country in 1868. He made his entrance into Madrid as king on 2nd Jan., 1871, and took the oath to the constitution. His position was far from comfortable, however, and, having little hope of becoming acceptable to all parties, he abdicated in 1873 (11th Feb.). He died in 1890.
