DE REKZKE, Jean, singer, b. in Warsaw, Po- land, 14 Jan., 1852. From an early age his voice showed remarkable qualities ; his parents, however, destined him for the bar and educated him with this end in view. Although he took his examina- tion and received the degree of advocate, he soon gave up his profession and devoted himself to music. He studied under Ciaffei, and in 1874, by the advice of Cotogni, made his first appearance as baritone at La Fenice, in Venice. His voice, how- ever, was tenor, rather than baritone, and after some years ho retired from the stage, on the advice of Sbriglia, to prepare himself for tenor parts. The event justified the step, for on his reappearance, at Madrid, his success was great; from Madrid he went to London, and in 1885 he appeared in grand opera at Paris. Later he became a great favorite in operas given in the leading cities of this coun- try. — His brother Eduard, singer, b. at Warsaw, 23 Dec, 1855, has made a reputation equally great as a bass singer. He intended to devote himself to scientific agriculture upon the family estate, but, upon the advice of his brother, he took up the study of music, under Stella and Alba, in Milan, and Coletti, in Naples. After four years he went to Paris and studied with his broth- er under Sbriglia. The two brothers have been favorites in grand opera in Paris and the other capitals of Europe; they have had equal if not, iiKleetl, greater appreciation in the United States, where they have sung for manv seasons.

While on this tour he discovered, among massive stone pillars, a small sione bearing on two sides graven characters of an unknown language. The stone was afterward sent to Paris, and there the resemblance the characters were thought to liear to the Tartaric was regarded as supporting the hypothesis of an Asiatic immigration into America. The king of France conferred the cross of St. Louis upon De Varennes, and at the time of his death he was about to resume, by the king's desire, his attempt to reach the Pacific ocean.
