Campbell, Byron, Roscoe, and others, and which incidentally cleared up some disputed questions. Roscoe, the author of the Life of Leo X., published his edition of Pope in 1824. A life is contained in the first volume, but it is a feeble performance; and the notes, many of them directed against Bowles, are of little value. A more complete biography was published by R. Carruthers (with an edition of the works), in 1854. The second, and much improved, edition appeared in 1857, and is still the most convenient life of Pope, though Mr. Carruthers was not fully acquainted with the last results of some recent investigations, which have thrown a new light upon the poet's career. The writer who took the lead in these inquiries was the late Mr. Dilke. Mr. Dilke published the results of his investigations (which were partly guided by the discovery of a previously unpublished correspondence between Pope and his friend Caryll), in the _Athenaeum_ and _Notes and Queries_, at various intervals, from 1854 to 1860. His contributions to the subject have been collated in the first volume of the _Papers of a Critic_, edited by his grandson, the present Sir Charles W. Dilke, in 1875. Meanwhile Mr. Croker had been making an extensive collection of materials for an exhaustive edition of Pope's works, in which he was to be assisted by Mr. Peter Cunningham. After Croker's death these materials were submitted by Mr. Murray to Mr. Whitwell Elwin, whose own researches have greatly extended our knowledge, and who had also the advantage of Mr. Dilke's advice. Mr. Elwin began, in 1871, the publication of the long-promised edition. It was to have occupied ten volumes--five of poems and five of correspondence, the latter of which was to include a very large proportion of previously unpublished matter. Unfortunately for all students of English literature, only two volumes of poetry and three of correspondence have appeared. The notes and prefaces, however, contain a vast amount of information, which clears up many previously disputed points in the poet's career; and it is to be hoped that the materials collected for the remaining volumes will not be ultimately lost. It is easy to dispute some of Mr. Elwin's critical opinions, but it would be impossible to speak too highly of the value of his investigations of facts. Without a study of his work, no adequate knowledge of Pope is attainable.
