[Ochterlony, Sir David], British general, born at Boston, U.S., of Scottish descent; entered the Indian army; distinguished himself in the war against the Goorkhas; was made a baronet, and received a pension of £1000 for his services; a monument to his memory stands in the Maidan Park, Calcutta (1758-1825).

[Ockley, Simon], Orientalist, became professor of Arabic; wrote a "History of the Saracens," part of it in a debtors' prison; died in indigence (1678-1720).

[O'Connell, Daniel], Irish patriot, known as the "Liberator," born near Cahirciveen, co. Kerry; educated at St. Omer, Douay, and Lincoln's Inn; was called to the Irish bar in 1798, and was for twenty-two years a famous and prosperous practitioner on the Munster circuit; turning to politics he became leader of the Catholics in 1811, his object being the removal of the Catholic disabilities; the Catholic Association of 1823 was organised by him, which he induced the priesthood to join, and awakened irresistible enthusiasm throughout the country; the electors now began to vote independently, and O'Connell was returned for Clare in 1828; the House refused to admit him; but so strong, and at the same time so orderly, was the agitation in Ireland, that in 1829 the Catholic disabilities were removed, and O'Connell, returned again for Clare, took his seat in the House of Commons; next year he represented Waterford in the new Parliament, and subsequently Kerry, Dublin, Kilkenny, and Cork; he now formed a society for promoting the repeal of the Union, which survived several suppressions, and reappeared under different names; but in spite of his exertions in the House and in the country the cause languished, till, in 1843, as Lord Mayor of Dublin, he carried a resolution in its favour in the City Council; but now under the pressure of less experienced agitators, his monster meetings and other proceedings began to overstep legal limits, and in 1844 he, with six of his supporters, was indicted for raising sedition; he was sentenced to a year's imprisonment and a fine of £2000, but the sentence was set aside in 14 weeks; by this time the Young Ireland party had broken away from him, the potato famine came, he was conscious of failure, and his health was broken; he died on his way to Rome, at Genoa; a man of great physical strength and energy, and a master of oratory, he gave himself unselfishly to serve his country, sacrificing a legal practice worth £7000 a year, honestly administering the immense sums contributed, and spending his private means for his cause; with an undeniable taint of coarseness, violence, and scurrility in his nature, he was yet a man of independent and liberal mind, an opponent of rebellion, loyal to his sovereign, a great and sincere patriot (1775-1847).

[Octavia], the sister of Augustus, a woman distinguished for her beauty and her virtue; was married first to Marcellus, and on his death to Mark Antony, who forsook her for Cleopatra, but to whom she remained true, even, on his miserable end, nursing his children by Cleopatra along with her own; one other grief she had to endure in the death of her son [Marcellus] (q. v.) by her former husband, and the destined successor of Augustus on the throne.

[October], the tenth month of the year so called (i. e. the eighth) by the Romans, whose year began on March.

[Od], name given to a physical force recently surmised and believed to pervade all nature, and as manifesting itself chiefly in connection with mesmeric phenomena.

[Oddfellows], the name of several friendly societies. The Independent Order of Oddfellows, Manchester Unity, is the largest and most important of the number, its membership is over 665,000, and its funds amount to £8,000,000. It has been the pioneer in many important movements of the kind, several of the provisions now compulsory on all societies it observed of its own accord, prior to their enactment; the actuarial tables compiled from its statistics in 1845 by its secretary, Henry Radcliffe, are still a standard work. The Grand United Order of Oddfellows has a membership of 241,000, and funds amounting to £882,000; the National Independent Order of Oddfellows embraces 58,000 members, and has £242,000.

[Oder], an important German river, rises in Moravia, and crossing the frontier flows NW. through Silesia, and N. through Brandenburg and Pomerania 550 m. into the Stettiner Haff and so to the Baltic. On its banks stand Ratibor, where navigation ends, Breslau, Frankfort, and Stettin; it receives its chief tributary, the navigable Warthe, on the right, and has canal communication with the Spree and the Elbe.

[Odessa] (298), on the Black Sea, 25 m. NE. of the mouth of the Dniester, is the fourth largest city of Russia, and the chief southern port and emporium of commerce. It exports large shipments of wheat, sugar, and wool; imports cotton, groceries, iron, and coal, and manufactures flour, tobacco, machinery, and leather. It is well fortified, and though many of the poor live in subterraneous caverns, is a fine city, with a university, a cathedral, and a public library. It was a free port from 1817 till 1857. The population includes many Greeks and Jews.

[Odin] or Wodin, the chief god of the ancient Scandinavians, combined in one the powers of Zeus and Ares among the Greeks, and was attended by two black ravens—Hugin, mind, and Munin, memory, the bearers of tidings between him and the people of his subject-world. His council chamber is in [Asgard] (q. v.), and he holds court with his warriors in [Valhalla] (q. v.). He is the source of all wisdom as well as all power, and is supposed by Carlyle to have been the deification of some one who incarnated in himself all the characteristic wisdom and valour of the Scandinavian race; Frigga was his wife, and Balder and Thor his sons.
