Letter, from George Henry Noehden to Sir John Herschel, dated at The Albany, London Autograph letter signed by sender. Is grateful for John Frederick William Herschel's assistance regarding the Persepolitan writing. G. C. Renouard's communication appears to be conclusive. Hopes he can convey the information to the Royal Society of Göttingen. Would like a copy of the whole inscription if this is not imposing too much. 3 August 1817
