Swift's Works

In Wilde's *Closing Years of Dean Swift's Life* (2d edit. p. 78.) is mentioned an autograph letter from Sir Walter Scott to C.G. Gavelin, Esq., of Dublin, in the MS. library. T.C.D., in which he states he had nothing whatever to do with the publication or revision of the second edition of the *Works of Jonathan Swift*. This does not agree with the statement given in Mr. Lockhart's *Life of Sir Walter Scott*, 2d edit. vol. vii. p. 215. Who was the editor, and in what does the second edition differ from the first?
