Sends paper from [Erik] Acharius to be read at Linnean Society in due course. "Grieves [...] deeply" to hear that "it is all over" with his "old & valued friend", [Thomas] Marsham; but takes consolation that "the warning afforded by losing elderly friends is rather soothing than dreadful", in comparison to sudden sorrow of losing younger friends.

He is setting of on a 6 week tour tomorrow with [Thomas William] Coke, one of his "best-loved friends", to Staffordshire, Wales, Lancashire, Cumberland, and Northumberland; looking forward to seeing [William] Roscoe, [Thomas] Johnes, and Bishop of Carlisle [Samuel Goodenough].

Sorry to hear that Marsham has disappointed [James] Sowerby as to money, fears "all is not right".
