Letter from Richard Owen, British Museum, to Sir John [Frederick William Herschel] 'Dear Sir John I feel much indebted to you for the pleasure you have given me in a closer acquaintance with the mode & powers of thought of the old Poet [Homer], through the rendering of a characteristic portion of his immortal work ['The Iliad'] by a congenial mind. Believe me most truly yours Richard Owen.' 29 April 1863
