Jakob Leonard Chodzko, a Polish scholar, born at Oborek, in the neighborhood of Wilna, Nov. 6,1800. He studied at Molodeczno, where he enjoyed the friendship of Zan, and at Wilna, under the guidance of the historian Lelewel. Having travelled as secretary of Prince Ogin-ski through nearly all Europe, he established himself in 1826 in Paris, where he published a memoir of the prince, with an introduction entitled Ohscrvations sur la Pologne et les Polo-nais (Paris, 1827), and commenced collecting materials for a history of his country from the death of Augustus III. Afterward he published Histoire des legions polonaises en Italic (2 vols., Paris, 1829), and several other works relating to Poland. During the revolution of July, 1830, Lafayette appointed him his aide-de-camp; and after the outbreak of Nov. 29 of the same year in Warsaw, he acted as agent of the revolutionary government in France. He was an active member of the French-Polish and American-Polish committees. His writings include Taoleau des revolutions de la Pologne (1837); La Pologne historique, litteraire, monmnentale, etc. (3 vols. 8vo, 1834-'47); Ilistoire de Pologne (4to, 1855; 14th ed., 8vo, 1864); Histoire de Turqvie (4to, 1855); and Contes des paysans et des patres slaves (1864).

CHŒNIX (Gr.Jakob Leonard Chodzko 0400246 ), a dry measure of capacity among the ancient Greeks. Its size is variously given, and it is probable that it differed in the different states of Greece. Some accounts represent it as containing three cotylae, or about 1.487 pint English; others make it equal to 1.982 pint; and still others give it as equal to 3.964 pints. The choenix appears to have been the daily allowance for one man, differing probably for various kinds of grain.

A Greek epic poet of Samos, who flourished in the 5th century B. C. He was a friend of Herodotus. A few fragments only are preserved of his poems.
