CD has come home – little altered in looks and otherwise not a bit changed. He will go to London to be there when Beagle arrives, and he and Caroline will visit Maer soon.

Describes CD’s visit to Maer on his return from Beagle voyage.

Regrets he cannot come to music meeting in Birmingham because he is very busy with the proofs of his book [Journal of researches]. A waste of life to spend a summer in ugly Marlborough Street.

Sends information about, and dates of treatment of peaty fields. Marl seems to have sunk to the natural stratum of hard white sand which lies below the peat.

Thanks for "Maer Hypothesis" ["Formation of mould" (1840), Collected papers 1: 49–53].
