Summary

Will secure information on indigenous and naturalised bees as CD requests.

Believes Mexican and Jamaican Melipona are different.

Summary

Relieved by Wallace’s letter.

At work on introductory essay to Flora Tasmaniae.

European plants naturalised in Australia are almost all adapted to invading disturbed ground.

JDH supports Asa Gray against Alphonse de Candolle as foreign member of Royal Society.

Summary

Is sorry to hear of bad health of CD and his daughter.

Discusses, with an example, the difficulty of explaining structural differences between closely allied species.

Summary

Serial homologies in the Mollusca. Gives instances of repetition of homological parts in Radiata.

Summary

Outlines the basic categories of phanerogams.

Places Gymnospermae in the dicotyledons.

Evaluates the variable utility of embryological characters in plant classification.

Summary

Embryology of Diptera. Development of insects; metamorphosis. JL feels all insects go through metamorphosis but that in some of them, part takes place before birth.

Summary

On the strength of CD’s details about his work on species and his knowledge of CD’s former publications, JM offers to publish [Origin] without seeing the MS.

Summary

Lyell has been strongly urging John Murray to publish CD’s book [Origin]. JDH feels Lyell overestimates the public interest in such works.

Gives examples of plants showing most marked varieties on the edge of their range.

Summary

Reports his observations on the habits of slave-making ants (Formica sanguinea).

Summary

Suggests giving Marcus Huish permission to shoot over CD’s Beesby estate, but not to revoke JH’s occasional privilege to take a visitor shooting there.

Summary

Summary

The antlers of 800 deer of the glacial period have been found in a cave. They show great variety of form, but gradation from one to the other can be traced when all are laid out. Suggests CD study changes that have taken place in the species since glacial period.

Has ordered the wicked book [Origin] CD has been so long a-hatching.

Summary

Since dogs have same gestation period as the wolf it is likely that the wolf is the ancestral wild species, if it is just one species.

CD’s belief that domestic dogs are descended from several distinct aboriginal species seems to contradict views on sterility of hybrids and variation in Origin. If domestic varieties came from hybrids of wild species it will be impossible to trace ancestry. Opponents will exploit these problems.

Summary

By this post he sends for approval specimen copy of CD’s book [Origin of species]. At 14 s., 1250 copies will yield £240, two-thirds of which will go to author. Arrangements for early copies.

Summary

Will welcome CD’s work [Origin] with a "close & continuous perusal".

Believes in the "operation of existing influences or causes in the ordained becoming and incoming of living species" and so could not regard CD’s attempt to demonstrate the nature of such influences as "heterodox".
