, are in existence. The first is contained in Moore's
Life
(1830); the second was published in America, in FitzGreene Halleck's edition of Byron's
Works
(1847); of the third, edited by Mr. W. E. Henley, only the first volume has yet appeared. A comparison between the letters contained in these three collections and in that of Mr. Murray, down to December, 1813, shows the following results: Moore prints 152 letters; Halleck, 192; Mr. Henley, 231. Mr. Murray's edition adds 236 letters to Moore, 196 to Halleck, and to Mr. Henley 157. It should also be noticed that the material added to Moore's
Life
in the second and third collections consists almost entirely of letters which were already in print, and had been, for the most part, seen and rejected by the biographer. The material added in Mr. Murray's edition, on the contrary, consists mainly of letters which have never before been published, and were inaccessible to Moore when he wrote his
Life
of Byron.
