[The note on vegetarianism beginning at p. 211 of Shelley's edition of Queen Mob was, after the issue of that poem in 1813, made the substance of a pamphlet of which the title page is reproduced opposite. Internal evidence shews the pamphlet to have followed and not preceded Queen Mob. The alterations and additions are not very important; but the inclusion of this extremely rare and highly characteristic tract in the series of the Prose Works seemed more desirable than the plan of merely giving the variations with the notes to Queen Mob. The Vindication is a 12mo. pamphlet consisting of fly title (as at back of this note), title page as given in facsimile opposite, pp. 1 to 39 of text, and pp. 41 to 48 of Appendix. As mentioned at p. 551 of the fourth volume of the Poetical Works (Library edition), there is a copy in the British Museum with the bottom of the title page (including the date) torn off. The fly title is also wanting. My own copy, from which this reprint is made, is perfect, and is the only one I ever saw or heard of beside that in the Museum. I believe this little treatise was reprinted as an Appendix to an American Medical work (Dr. Turnbull's Manual on Health, New York, 1835); but, not having been able to see a copy of this book, I cannot say whether the pamphlet or the Queen Mob note is there reprinted.—H.
