Hopes Murray will publish after seeing MS [of Origin].

Demurs at JDH’s saying that CD changes climate to account for migration of bugs, flies, etc. "We do nothing of the sort; for we rest on scored rocks, old moraines, arctic shells, and mammifers." Has given up the Lyellian doctrine as insufficient to explain all changes in climate; CD has no theory about the cause of the cold.

CD has heard from Lyell that JM is inclined to publish his work on the origin of species. Will send some chapters as soon as copyist has finished. Sends list of 12 chapters. It will be a popular abstract of more than 20 years’ work. It ought to be popular with scientific and semi-scientific readers.
