“ In 1877 Chrystal left Cambridge to become professor of mathematics at St. Andrews university, and two years later he was elected to the chair of mathematics at Edinburgh (Nov. 1879) . There he greatly stimulated interest in mathematics in the university through the clearness and conciseness of his expositions of mathematical theory. At the same time he actively interested himself in the general academic organisation. Elected dean of the faculty of arts in 1891, he rendered valuable service in reorganising the arts curriculum. ”

“ An important treatise on ‘Trilinear Co-ordinates and other Methods of Modern Analytical Geometry of Two Dimensions’ was issued at Cambridge in 1866. Whitworth's best-known mathematical work, entitled ‘Choice and Chance, an Elementary Treatise on Permutations, Combinations and Probability’ (Cambridge, 1867) , was elaborated from lectures delivered to ladies at Queen's College, Liverpool, in 1866. A model of clear and simple exposition, it presents a very ample collection of problems on probability and kindred subjects, solutions to which were provided in ‘DCC Exercises’ (1897) . ”

“ BURBURY, SAMUEL HAWKSLEY (1831–1911) , mathematician, born on 18 May 1831 at Kenilworth, was only son of Samuel Burbury of Clarendon Square, Leamington, by Helen his wife.
