Horace Walpole, a younger son of the celebrated prime minister, (died March 13, 1746,) was born at Wareham, in Dorsetshire, Oct. 5, 1717, and died at London, March 2, 1797. His principal works are; A Catalogue of Royal and Noble Authors, 1756; Anecdotes of Painting in England, 1791; Catalogue of Engravers in England, 1762; History of the last ten years of George II.; and a romance called the Castle of Otranto, which acquired great popularity, and was successfully imitated by Miss Clara Reeve, in her story of the Old English Baron, in 1777. Personally, and also in his manner of writing, Walpole was eccentric and heartless; but the ease, pungency, and brillancy of his style, will long keep his works before the public. He succeeded a nephew in the earldom, nearly at the close of his life.
