The text of this edition of Don Juan has been collated with original MSS. in the possession of the Lady Dorchester and Mr. John Murray. The fragment of a Seventeenth Canto, consisting of fourteen stanzas, is now printed and published for the first time. I have collated with the original authorities, and in many instances re-transcribed, the numerous quotations from Sir G. Dalzell's Shipwrecks and Disasters at Sea (1812, 8vo) [Canto II. stanzas xxiv. -civ. pp. 87-112], and from a work entitled Essai sur l'Histoire Ancienne et Moderne de la Nouvelle Russie, par le Marquis Gabriel de Castelnau (1827, 8vo) [Canto VII. stanzas ix. —liii. pp. 304-320, and Canto VIII. stanzas vi. —cxxvii. pp. 331-368], which were first included in the notes to the fifteenth and sixteenth volumes of the edition of 1833, and have been reprinted in subsequent issues of Lord Byron's Poetical Works.
