Sends MS of 13 pages in answer to Nägeli, for new edition of Origin [5th ed., p. 151].
Finds JDH’s comments of utmost value. Answers some questions, and asks new ones. Transmission of variations. Relation of uniformity of structure to natural selection.
No paradox that unimportant characters are important systematically. This view removes heavy burden from CD’s shoulders. Relief that JDH does not object.
Oliver overlooked CD’s request about rutaceous flowers. Of precisely which points about the ovules does CD want illustrations?
Criticisms of and suggestions for CD’s draft MS on Nägeli [for Origin, 5th ed.].
Replies to CD’s questions. Advice on use of term "morphology". Is much struck by CD’s idea that uniformity of an organ throughout a group implies functional inutility; the paradox of this position for classification.
Does not fact that characters important in systematics are often of no use, corroborate CD’s view that such characters, if not detrimental, may persist ad infinitum?
