My dear Nicholson,
        I am again at work at the Berber MS., which I have not touched since the 1st October. The Royal Asiatic Society have accepted my offer to edit it. At present their pages are occupied with the history of Darius Hystaspis from the rocks at (I think) Besittoon, near Hemadon—the most curious document which recent research has brought to light, and, I am told, confirming in detail the accounts of Herodotus.
