nesse,' 8vo, London [1555]. He therewith sent verses and adages written with the hand of Henry Stuart, lord Darnley, the bishop's nephew, within twelve months past, Elder then being with Darnley, who was not full nine years of age, at Temple Newsome, Yorkshire. He also refers to Darnley's noble parents as his singular good patrons. The letter is reprinted in 'The Chronicle of Queen Jane,' Sec. (Camd. Soc.) Elder was not M. A. of either Oxford or Cambridge. The Elder incorporated at Oxford as being M.A. of Cambridge, 30 July 1561 (Wood, Fasti Oxon., ed. Bliss, i. 159), was probably Arthur Elder, who had supplicated for the degree as long ago as 25 June 1556 (Reg. of Univ. of Oxf., Oxf. Hist. Soc, i. 233).

ELDER, JOHN (1824–1869), marine engineer and shipbuilder, was born at Glasgow on 8 March 1824. His family was connected with Kinross, where for several generations his forefathers had followed the occupation of wrights, for which they seemed to have a special aptitude. His father, David Elder, settled in Glasgow, and entered the establishment of Mr. Napier, the well-known shipbuilder, under whom, in 1822, he constructed the first marine engine, which was fitted up in the river Leven for the passage between Glasgow and Dumbarton. David Elder was the author of many inventions and improvements in the machinery of steam vessels, and to the excellence of his engines the success of the Cunard line of steamers, in establishing regular communication between the opposite shores of the Atlantic, was mainly due. He died in January 1866, in his eighty-second year. John Elder was his third son; he was educated at the high school of Glasgow, where he showed great excellence in mathematics and in drawing. After a five years' apprenticeship to Mr. R. Napier, and a brief time passed in English engine works, he was placed at the head of the drawing office in Napier's works. In 1852 he became a member of the firm of Randolph, Elliott, & Co., a firm that had been successful as millwrights, but had not attempted anything as marine engineers. In 1860 they began shipbuilding under the firm of Randolph, Elder, & Co.; in 1868, on the expiry of the copartnery. Elder continued the business, which reached a very great degree of prosperity. He soon became known as an engineer of singular ability. The greatest service which Elder rendered to practical engineering was the adoption of the compound or combined high and low pressure engines. Various attempts at this combination had been made before, but they had failed, owing to causes which engineers either did not understand or could not overcome. Where they had failed, Elder succeeded. Professor Macquorn Rankine, who has gone into all the details of the subject in his memoir of Elder, says that only one who had thoroughly studied and understood the principles of thermo-dynamics could have achieved this. A saving of fuel amounting to thirty or forty per cent, was effected. Elder took out many patents for improvements in marine machinery. Of some of his improvements he gave an account in papers presented to the British Association at Leeds in 1858, Aberdeen 1859, and Oxford 1860. In 1868 he read a paper before the United Service Institute in London on an improved form of war-ship, entitled 'Circular Ships of War, with immersed motive power.' In 1869 he was unanimously chosen president of the Institution of Engineers and Shipbuilders of Glasgow.
Some idea of the magnitude of his business may be formed from the fact that when in business by himself he employed four thousand men, and that from June 1868 to the end of 1869 the number of sets of engines made by him was eighteen, their aggregate horse power 6,110, the number of vessels built fourteen, their aggregate tonnage 27,027.
During 1869 he was ill for several months. He proceeded to London to get the best advice, but while there he was cut off by disease of the liver at the early age of forty-five. Elder married in 1857 Isabella, daughter of A. Ure, esq., of Glasgow. Mrs. Elder, since her husband's death, besides adding largely to the endowment of the chair of civil engineering and applied mechanics in the university of Glasgow, has recently provided an endowment for a chair of naval architecture.
Elder, as Professor Rankine remarks, was a genius in engineering. In person he was remarkably handsome, and in manner and character very attractive. He was quick and energetic in all his movements, full of resource, and remarkably enterprising. His character stood very high. Dr. Norman Macleod and others who knew him intimately pronounced him one whose great aim was to translate the facts of Christ's life into his own, especially in matters of common life. With his workpeople he was on the best of terms. He was much interested in schemes for their social, intellectual, and religious welfare; organised and contributed largely to a sick fund, and was contemplating the erection of schools and model houses on a large scale, when death ended his career. After his death the men in his employment, in begging to be
