1823 is the year of the tract on the _Measure of Value_ and the _Quarterly_ article on Tooke; 1824 of the paper on Population in the _Supplement to the Encyclopædia Britannica_, and the article on the New Political Economy in the _Quarterly Review_.[997] In 1825 he lost a daughter, and went for his own and his wife’s health to the Continent. In that year he contributed his first paper to the Royal Society of Literature, of which he had been made an Associate two years before; and that year saw Empson take the place of Mackintosh at Haileybury. In 1826 was published the sixth edition of the essay, the last published in his lifetime. In 1827 we find him before the Emigration Committee, and we have from his pen the _Definitions in Political Economy_, and the second paper contributed to the Royal Society of Literature. In 1829 letters passed between him and W. Nassau Senior, which were appended by the latter to his _Lectures on Population_. In 1830 he wrote the _Summary View_, which involved no new effort. Indeed his whole time seems to have been spent in revising his _Political Economy_ in the light of his public and private discussions with Ricardo, though he did not live to print the new edition himself. Shortly before his death he said to some one who rebuked him for his delay: “My views are before the public. If I am to alter anything, I can do little more than alter the language, and I don’t know if I should alter it for the better” (Empson, _l. c._ p. 472). He was one of the first Fellows of the Statistical Society, founded in March 1834, and its first Annual Report contains a high eulogy on him and his work; but he did not live to take much share in its proceedings. He died suddenly of heart disease on Monday, 29th December, 1834, on a visit to Mr. Eckersall at St. Catherine’s, where he was spending Christmas with his wife and family. He is buried in the Abbey Church at Bath, in the north aisle of the nave. Of his three children, two survived him, of whom one, a daughter, is still living.[998]
