Replies to note from CL asking about views of glaciers.

Discusses David Milne’s Glen Roy paper ["On the parallel roads of Lochaber", Trans. R. Soc. Edinburgh 16 (1849): 395–418]. Rejects Milne’s theory that outlet of Glen Roy is blocked by detritus.

Offers arguments against glacier theory.

Ask JR to advise the Queen to issue Her Royal Commission of Inquiry into the best methods of securing the improvement of the Universities of Oxford and Cambridge.

Criticises at length the concept of submerged continents attaching islands to the mainland in the recent period. Notes drastic alteration of geography required, the dissimilar species on opposite shores of continents, and differences between volcanic islands and mountains of mainland areas. Admits sea-bed subsidence, but not enough to engulf continents. Denies that theory can explain island flora and fauna.
