stitution of the Scottish Universities, and on the recognition of the 
right of the graduates to a share in their government, and he 
organised the first association formed for that purpose. He held 
strongly that the educational system of Scotland ought to preserve 
its distinctive character, instead of being administered from London 
and assimilated to that of England. Among minor reforms which 
he advocated was that of the introduction of a decimal system of 
coinage, weights, and measures, on which he wrote a short hut

author of several educational hooks, such as treatises on algebra, 
geometry, and the elements of astronomy, and a cyclopaedia of geo- 
graphy. Most of these have gone through several editions.

freshness of youth, but a perfect sweetness of temper, and an 
ungrudging readiness to plate his time and knowledge at the service 
of others, which advancing years seldom spare. 
His memory as that of one of the most lovable of men will be 
long cherished by hundreds of former pupils, with many of whom, 
scattered through India and the Colonies, he kept up intimate rela 
tions, and by the large circle - of scientific friends whom he was 
accustomed to meet year after year at the meetings of the British 
Association and of our own learned societies.

very old Highland family of that name, was the youngest son of 
James Drummond of Strageath, and was bom at Edinburgh on

profession; but he subsequently proceeded to Worcester College, 
Oxford, where he took his bachelor’s degree in 1830. He was 
ordained a deacon the same year by the Bishop of Llandaff, and 
a priest in 1831 by the Bishop of Gloucester and Bristol. Eor 
the first two years of his ministry he occupied the office of 
curate at Henbury and Compton, and then came to Edinburgh, 
where he entered into the incumbency of St Paul’s Episcopal
