Being engaged upon a biography of Major André, he has already collected considerable matter; but wishes to leave no stone unturned in his task, and therefore begs his brethren of "N. & Q." to publish therein any anecdotes or copies of any letters or documents concerning that gallant but ill-fated gentleman. A reference to passages occurring in printed books bearing on this subject, might also well be given; for there is so little known about Major André, and that little scattered piecemeal in so many and various localities, that it is hardly possible some of them should not have escaped this writer's notice. SERVIENS. [Smith's _Authentic Narrative of Major André_, 8vo. 1808, has most probably been consulted by our correspondent. There is a good account of the Major in vol. ii. of the _Biographical Dictionary_ of the Useful Knowledge Society, and it is worth consulting for the authorities quoted at the end of the article. See also the _Encyclopædia Americana_, article "Benedict Arnold;" the _American Whig Review_, vol. v. p. 381.; _New England Magazine_, vol. vi. p. 353.; and for a vindication of the captors of André, the _Analectic Magazine_, vol. x. p. 307. Articles also will be found respecting him in _Gentleman's Magazine_, vol. l. pp. 540. 610.; vol. li. p. 320.; vol. lii. p. 514. Major André is one of the principal subjects of _The British Hero in Captivity_, a poem attributed to Mr. Puddicombe, 4to. 1782.] "_The Fatal Mistake._"--Can you tell me where the scene of the following play is laid, and the names of the _dramatis personæ_: _The Fatal Mistake, a Tragedy_, by Joseph Haynes, 4to., 1696? The author of this play, who was known by the name of Count Haynes, was an actor in the theatre at Drury Lane about the time of James II., and died in 1701. There is an account of his life written by Tom Browne. GW.
