Some account has already been given of this Letter in the Advertisement to the fourth quarto volume.[2] That part of it which is contained between the first and the middle of the page 67[3] is taken from a manuscript which, nearly to the conclusion, had received the author's last corrections: the subsequent part, to the middle of the page 71,[4] is taken from some loose manuscripts, that were dictated by the author, but do not appear to have been revised by him; and though they, as well as what follows to the conclusion, were evidently designed to make a part of this Letter, the editor alone is responsible for the order in which they are here placed. The last part, from the middle of the page 71, had been printed as a part of the Letter which was originally intended to be the third on Regicide Peace, as in the preface to the fourth volume has already been noticed. It was thought proper to communicate this Letter before its publication to Lord Auckland, the author of the pamphlet so frequently alluded to in it. His Lordship, in consequence of this communication, was pleased to put into my hands a letter with which he had sent his pamphlet to Mr. Burke at the time of its publication, and Mr. Burke's answer to that letter. These pieces, together with the note with which his Lordship transmitted them to me, are prefixed to the Letter on Regicide Peace. II. Letter to the Empress of Russia. III. Letter to Sir Charles Bingham. IV. Letter to the Honorable Charles James Fox. Of these Letters it will be sufficient to remark, that they come under the second of those classes into which, as I before observed, we divided the papers that presented themselves to our consideration. V. Letter to the Marquis of Rockingham. VI. An Address to the King. VII. An Address to the British Colonists in North America. These pieces relate to a most important period in the present reign; and I hope no apology will be necessary for giving them to the public. VIII. Letter to the Right Honorable Edmund [Sexton] Pery. IX. Letter to Thomas Burgh, Esq. X. Letter to John Merlott, Esq. The reader will find, in a note annexed to each of these Letters, an account of the occasions on which they were written. The Letter to T. Burgh, Esq., had found its way into some of the periodical prints of the time in Dublin. XI. Reflections on the Approaching Executions. It may not, perhaps, now be generally known that Mr. Burke was a marked object of the rioters in this disgraceful commotion, from whose fury he narrowly escaped. The Reflections will be found to contain maxims of the soundest judicial policy, and do equal honor to the head and heart of their illustrious writer. XII. Letter to the Right Honorable Henry Dundas; with the Sketch of a Negro Code.
