Thanks WCW for his article ["Microscopical objects found in mud of Levant", Mem. Lit. & Philos. Soc. Manchester 2d ser. 8 (1848):1–128]. Comments on it; offers to send Ascension Island specimens. Urges WCW to re-examine coal-beds for Infusoria to determine whether intervening beds were deposited by sea-, brackish, or fresh water.
