A fossil ungulate mammal of the size of a camel, found in the Pleistocene beds of Argentina.

He was born in London, March 3, 1793. the son of a provincial theatrical manager, and was edu- cated at Kugbj'. He first played as Romeo at Birmingluim in 1810. For four years he took leading parts in his father's company, and two years later, in September, 1816, made his first appearance before a London audience as Orestes in The Distressed Mother, winning the applause of Kean. Macready's progress in the higher walks of the drama was slow, however, largely on account of professional jealousies. In 1819 he made a hit in the character of Richard IIL, and afterwards adventured on others of Shakespeare's characters with success. In 1826 he made a tour of the United States, and vis- ited Paris in 1828. He became lessee of Co- vent Garden Theatre in 1837. and his manage- ment, though brief, was distinguished by the high character of his company and his productions. Later he managed Drury Lane for a time, but without pecuniary success. He visited America a second time in 1843-44; and again in 1848-49, when lie barely escaped with his life from a riot which took place in the Astor Place Opera House at New York (May 10, 1849), as a result of the jealousy of the American actor Edwin Forrest. On his return home ilacready was engaged at the ' Haymarket, but his theatrical career was brought to a conclusion with his farewell benefit at Drury Lane, on February 20, 18.51. He died at Cheltenham on April 27, 1873. Macready was a fine and impressive player, and a conscientious student of his art. He succeeded best in the graver characters of the drama, hav- ing more of the stateliness of Kemble than of the fire of Kean.

He was at once chosen Emperor by the army, and the Senate confirmed the choice. He fought against the Parthians. neither side gaining a decisive victory, made terms with them, and returned to Antioch.

A genus of about a dozen species of plants of the natural order Cycadacea", widely distributed over Australia. The fronds, which somewhat resemble those of palms, are used in the Roman Catholic Church on Palm Sunday. The underground stem, which is large and tur- ni|>-like, but covered with scales or leaf-scars, contains a substance resembling tragacanth. and is rich in starch, which may be readily obtained by grinding and washing. All the species con- tain a poisonous principle that is destroyed by hent. "The nuts of Macrozamia spiralis are ed-
