Summary

Asks for the address of C. W. Crocker.

Summary

Is JDH sure it is a Bletia, just received? Its pollen very different from any Epidendreæ he has seen. If it is Bletia, Lindley’s grand divisions are fanciful.

Accepts JDH’s offer to collect cases of dimorphism.

James Bateman has sent a lot of orchids with Angraecum sesquipedale. What a proboscis the moth that sucks its 11½ inch nectary must have!

Summary

For his father [James Bateman], he sends three more species of orchids and names of others described by CD.

Summary

His answer to Asa Gray.

On JDH’s view of aristocracy. Primogeniture is dreadfully opposed to selection.

Orchid book proofs ready soon – has no idea whether it is worth publishing.

Huxley on Owen.

Feeble letter from J. H. Balfour against Huxley’s lectures ["Relation of man to lower animals", pt 2 of Man’s place in nature (1863)].

Has received the "astounding" Angraecum sesquipedale with nectary 1ft long: "what insect could suck it?"

Summary

Glad CD approves of the orchids he sent.

Believes the pollinia of Mormodes are projected; thinks CD should look at the pollinia of Chysis and investigate the hybrid between Limatodes and Calanthe.

Summary

Pleased CD accepts continental extension for New Zealand, whose flora has many genera like Rubus with great diversity and connecting intermediates. Suggests geological uplifting creates more space, hence opportunities for preservation of intermediates. Sees clash with CD on causes of extreme diversity of form in a group.

JDH’s attitude toward democratisation of science.

Summary

Thanks CL for Hooker’s letter.

Discussion of Hooker’s views on glacial action and temperature with specific reference to S. America.

His squabbles with Hooker on transport of seeds via water currents,

temperate plants, and preservation of tropical plants during cooler period.

Expresses interest in seeing Agassiz’s letter.
