Autograph Letter Signed ('R. H. Horne') from the poet Richard Hengist Horne asking the playwright James Robinson Planché to pass on his play 'Gregory VII' to Charles Kemble, and stating that he has sent another play to George Bartley.

3pp., 16mo. Bifolium. Fair, on lightly-aged paper, with traces of previous mounting to the reverse of the last leaf. Horne writes that he is enclosing a copy of his play 'Gregory VII' for 'Mr Chas Kemble'. 'I have not written his name in it, because as you were so kind as to interest yourself in the matter, I thought I would leave it in your hands so you may give it him; or say you asked me for a copy for the purpose, or say nothing - or anything. Isn't this a fine mode of expressing my confidence in your judgment? - good taste, &c' In a postscript he states that he has sent his 'Cabinet Measures [a comedy, not performed or published] to Mr. Bartley to read, at his request.' He has done so 'only with a view to his seeing how I can write for a given company'. According to the Oxford DNB Horne had already 'besieged the actor-manager William Macready' about two other plays, and like them 'Gregory VII' was not staged.
