Would like to see JDH’s testimonials.

Disappointed with Kosmos.

Has visited Dean of Manchester, who is very heterodox on species.

Thanks for Antarctic flora [Flora Antarctica (1844–7)].

Agrees geographical distribution will be "the key which will unlock the mystery of species".

Could JDH look over a rough sketch on species?

Comments on JDH’s Flora Antarctica. CD is delighted with it.

"I can never cease marvelling at the similarity of the Antarctic floras: it is wonderful."

Questions JDH on points raised by the work: absence of alpine flora on southern islands; comparison of climate and floras of Tasmania and New Zealand.

Is busy with shell work and cannot make it to Kew. Invites JDH to Down. Intends asking Edward Forbes and Hugh Falconer.

Can JDH come to Down on 6 December? If this is convenient, CD will ask Forbes, Falconer, and perhaps Waterhouse.

Delighted that JDH will come to visit him.

CD’s enjoyment of JDH’s visit and "all our raging discussions".

Would like to compare insects from Kerguelen Islands with those from Tierra del Fuego.
