He writes that the bulk of the Paper has already been read before the Royal Asiatic Society but not published. He asks that Clarke will proof the Paper. He also sends a manuscript concerning the "mundane system of the Farsis". He writes that Mr Norris had sent 3 copies of one of Newbold's Papers that had recently been published but that he will require about 10 further copies and asks if Clarke will send copies with the Author's respects to the Foreign Societies, a list of which he has left with Mr Reid. He will also require 50 copies of his Mineral Resources and asks Clarke to manage this for him.
