GLACIER, a more or less snow-white mass of ice occupying an Alpine valley and moving slowly down its bed like a viscous substance, being fed by semi-melted snow at the top called neve and forming streams at the bottom; it has been defined by Prof.  J. D. FORBES (q. v.) as “a viscous body which is urged down slopes of a certain inclination by the mutual pressure of its parts”; in the Alps alone they number over 1000, have an utmost depth of 1500 ft., and an utmost length of 12 m.

GLADIATOR, one who fought in the arena at Rome with men or beasts for the amusement of the people, originally in connection with funeral games, under the belief, it is said, that the spirits of the dead were appeased at the sight of blood; exhibitions of the kind were common under the emperors, and held on high occasions; if the gladiator was wounded in the contest, the spectators decided whether he was to live or die by, in the former case, turning their thumbs downwards, and in the latter turning them upwards.

GLADSTONE, WILLIAM EWART, statesman, orator, and scholar, born at Liverpool, son of a Liverpool merchant, sometime of Leith, and of Ann, daughter of Andrew Robertson, Stornoway; educated at Eton and Oxford; entered Parliament in 1832 as member for Newark in the Tory interest; delivered his maiden speech on slavery emancipation on May 17, 1833; accepted office under Sir Robert Peel in 1834, and again in 1841 and 1846; and as member for Oxford, separating from the Tory party, took office under Lord Aberdeen, and in 1859, under Lord Palmerston, became Chancellor of the Exchequer; elected member for South Lancashire, 1865, he became leader of the Commons under Lord John Russell; elected for Greenwich, he became Premier for the first time in 1869, holding office till 1875; after a brilliant campaign in Midlothian he was returned for that county in 1880, and became Premier for the second time; became Premier a third time in 1886, and a fourth time in 1892.  During his tenure of office he introduced and carried a great number of important measures, but failed from desertion in the Liberal ranks to carry his pet measure of Home Rule for Ireland, so he retired from office into private life in 1895; his last days he spent chiefly in literary work, the fruit of which, added to earlier works, gives evidence of the breadth of his sympathies and the extent of his scholarly attainments; but being seized by a fatal malady, his strong constitution gradually sank under it, and he died at Hawarden, May 19, 1898; he was buried in Westminster Abbey at the expense of the nation and amid expressions of sorrow on the part of the whole community; he was a man of high moral character, transcendent ability, and strong will, and from the day he took the lead the acknowledged chief of the Liberal party in the country (1809-1898).
