[ Algernon Percy, 4th Duke of Northumberland. ] Two Autograph Letters Signed (both 'Northumberland') to Admiral William Henry Smyth, the first regarding 'Dr Braun in Rome', and the second sending condolences on the death of his daughter.

ONE: 2pp., 12mo. Bifolium with mourning border. In good condition, on lightly aged paper. He is enclosing a letter from 'Dr Braun in Rome', and suggests that Smyth will be able to correct the translation. 'I am sorry Dr Braun is not more successful, but he has zeal in the Cause, & will not lose an opportunity.' TWO: 3pp., 12mo. Bifolium. In good condition, on aged paper, with remains of mount on blank page. A letter of condolence on the death of Smyth's tenth child, Caroline Mary Smyth (1834-1859). Northumberland has refrained from writing while the death was 'a fresh wound', 'for I know that no human condolence could give you any solace to your grief'. His wife, who shares in his sentiments, thanks Mrs Smyth [ Eliza Anne Warington, the bluestocking 'Annarella' (1788-1873) ] for sending her a sermon, 'as it was an assurance of a kindly feeling, & of mutual sincere condolence'. The letter ends with news of a visit to Alnwick by Doctor Lee and his wife.
