_William Jones_, an eminent mathematician, was born in the Isle of Anglesey in 1680. At a very early age he applied himself diligently to the study of mathematics; and in his twenty-second year he published a “Compendium of the Art of Navigation,” which was much approved of. He began his career in teaching these sciences on board of a man-of-war; and he was present at the capture of Vigo. On his return to England, he gave instructions in the mathematics in London, and having attracted the notice of some influential men, he was appointed by Lord Hardwicke secretary of the peace. He enjoyed the friendship of the great mathematicians and writers of the age, among whom were Newton, Halley, Head, and Dr. Johnson. He was member of the Royal Society, and then vice-president. He was author of several valuable papers on mathematics, which were published in the Philosophical Transactions. He died of a polypus in the heart in July, 1749. Sir _William Jones_, the celebrated oriental scholar, was the son of the subject of the preceding article, and was born in London, September, 1746. He received his early education at Harrow School, where he was sent in his eighth year. He very soon attracted the notice of the masters by his splendid genius; and in 1764, he was entered at University College, Oxford. While here, he supported, at his own expense, a native of Aleppo, for the purpose of acquiring the true pronunciation of the Arabic. And having undertaken the office of tutor to Lord Althorpe, he went with him to the German Spa, where he perfected himself in the German language; and on his return, he distinguished himself by translating the “Life of Nadir Shah” into French, which language he wrote with much elegance. He obtained a college fellowship, and afterwards entered himself as a law student in the Temple. In 1772, he published some poems, and in the same year was elected a fellow of the Royal Society; and in 1774, he was called to the bar; about two years after, he was made commissioner of bankrupts. In the mean time, he published several works, chiefly in oriental literature, which excited the admiration of the world; and at the same time he was advancing rapidly in professional reputation. In an election for the University of Oxford he offered himself as a candidate, where, however, though respectably supported, he did not succeed. On the accession of the Shelburne administration, he obtained what had long been the summit of his ambition—the appointment of Judge in the Supreme Court of Judicature in Bengal, to which he was nominated in 1783, and received the honour of knighthood. He married Miss Shipley, the daughter of the Bishop of St. Asaph; and in the same year he arrived at Calcutta. While in India, he wrote numerous translations from the Hindostanee, and formed there a society, similar to the Royal Society of London, of which he was chosen the first president. He next undertook to compile a complete digest of the Hindoo and
