His health is weak and he is "almost smothered" with facts and inquiries, so is trying to restrict the scope of his present work, on variation under domestication.

CD will use "weeping trees" as an example of how inexplicable the laws of inheritance are, and asks for facts on character of seedlings.

Summary

Answers D. Beaton’s criticism of Gärtner’s work, defending his results in crossing experiments and vindicating the memory of "one of the most laborious lovers of truth who ever lived".

Summary

Thanks HBD for his lectures On the germs and vestiges of disease [1861].

Thinks his reasoning that the V. M. F. ("force exhibited in the operations of life") is not a "given quantity" is satisfactory.

Asks for source of the quotation on regeneration in HBD’s work.

Summary

Tells JS Acropera capsule should be left to grow.

JS was correct on "bud-variation" in fern frond.

Does not believe Primula structure necessarily related to dioecism, but the difference in fertility of the two forms forced him to admit the possibility.
