His first volume of poetry, entitled "A Rhymer's Plea for Tolerance " (1833), was followed in 1838 by "Poems, for the most part Occasional." His last work was entitled "A Day at Tivoli, with other Verses." He used his large fortune with great generosity, and is said to have left legacies to 80 persons, many of whom were his old literary friends, including B. W.

John Landen, an English mathematician, born at Peakirk, near Peterborough, in January, 1719, died Jan. 15, 1790. From 1762 to 1788 he was agent for Earl Fitzwilliam. His earliest mathematical writings appeared in the " Ladies' Diary" for 1744, and most of his subsequent papers were contributed to the " Transactions " of the royal society of London, of which he was admitted a member in 1766. He is best known by his "Residual Analysis " (London, 1764), in which he proposed a new form of fluxionary calculus, and invented a set of symbols. His plan has been thought an improvement on the method of ultimate ratios, but it lacks simplicity, and was never in general use. The principal other works of Landen are: "Mathematical Lucubrations " (4to, London, 1755); "Animadversions on Dr. Stewart's Computation of the Sun's Distance" (4to, 1771); "Observations on Converging Series " (4to, 1781); " Mathematical Memoirs" (2 vols. 4to, 1780-'89).
