Has finished geographical distribution chapter and asks JDH to read it.
Is it just to say embryological characters are of high importance in plant classification?
Will read JDH’s printers’ slips on variation.
CD has been so ill, he wonders whether he will get his book done, though so nearly completed.
Sends MS [of Origin] on geographical distribution. Wants JDH to correct facts and say what he most vehemently objects to.
Has received JDH’s note on plant embryology.
Will finish last chapter (except recapitulation) tomorrow.
Pleased with JDH’s response to geographical distribution chapter;
CD disagrees with Lyell’s view that glacial epoch is connected with position of continents.
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.
Outlines the basic categories of phanerogams.
Places Gymnospermae in the dicotyledons.
Evaluates the variable utility of embryological characters in plant classification.
