[_During the last stanza_ ROGERO _dashes his head repeatedly against the walls of his prison; and, finally, so hard as to produce a visible contusion; he then throws himself on the floor in an agony. The curtain drops; the music still continuing to play till it is wholly fallen._ [The character of ROGERO is a quiz upon SIR ROBERT ADAIR, who received his education at Göttingen, and fell in love with his tutor’s daughter. His relative, LORD ALBEMARLE, says in his _Reminiscences_: “Throughout life my kinsman was an enthusiastic admirer of the fair sex, which he generally ‘loved, not wisely, but too well’”. He married, in 1805, Mdlle. Angélique Gabrielle, daughter of the Marquis d’Hazincourt and the Comtesse de Champagne. ADAIR was the son of Mr. Robert Adair, sergeant-surgeon to K. George III., by his wife LADY CAROLINE KEPPEL, daughter of Wm. Anne, second Earl of Albemarle. He was educated at Westminster School and Göttingen University; called to the Bar, but never practised. He contested Camelford in 1796; and was M.P. for Appleby, 1799–1802, for Camelford, 1802–1812. He was sent by FOX as Minister Plenipotentiary to Vienna in 1806; and by his old adversary CANNING to Constantinople in 1808; and also to Berlin. He was Ambassador to Constantinople, 1809–11, and to Belgium, 1831–5. He was a facile writer, and wrote several spirited pamphlets, including defences of his relatives, Francis, Duke of Bedford, and Admiral Keppel, Fox, and other Whigs. He contributed to the _Political Eclogues_ a poem called _Margaret Nicholson_, in which George III., Pitt, Jenkinson, &c., were ridiculed, and the _Song of Scrutina_ (on the “Westminster Scrutiny”), in the style of Ossian, in the _Probationary Odes for the Laureateship_. He was the author also of an account of his _Mission to the Court of Vienna_; and his _Negotiations for the Peace of the Dardanelles_: 3 vols., 8vo. For his services in the latter business he was made G.C.B. He was born 24th May, 1763, and died 3rd Oct., 1855. There is a curious circumstance connected with the composition of this song, the first five stanzas of which were written by CANNING. Having been accidentally seen, previous to its publication, by PITT, who was cognisant of the proceedings of the “Anti-Jacobin” writers, he was so amused with it, that he took up a pen and composed the last stanza on the spot.—ED.] [This drama was produced at the Haymarket Theatre, July 26, 1811, with alterations and additions, and some introductory matter, which contained smart hits at the Quadrupeds, which then desecrated the stage of Covent Garden Theatre. Liston performed _Rogero_; Munden, _Casimere_; Mrs. Glover, _Matilda_; Mrs. Gibbs, _Cecilia_. The following Prologue, written by George Colman the younger, in imitation of Pope’s prologue to _Cato_, was spoken by Elliston:—
