JDH writes to his uncle, Reverend John Gunn, regarding recently published pamphlets on geology. Papers mentioned are written by: Sir Andrew Crombie Ramsay, John Tyndall & Charles Lyell [CL], plus a note by Hugh Falconer [HF] in ANNALS OF NATURAL HISTORY. JDH does not agree with HF's overzealous critique of a mistake by CL. Comments on the character of HF: a Scotsman JDH knows from India. JDH thinks the geology of the Suffolk valleys should be examined, suspects they are tidal not fluvial. JDH will send birds to Mr Smythe when Gunn provides the address.
