Regrets delay in returning CD’s books.
Encourages CD to make "disparaging remarks".
Thanks for criticism of proofs of his paper [see 5117].
Not sure whether CD believes in reversion and would like a positive statement as this is the one point C. V. Naudin especially observed. Naudin offers his remarks on ovules as a matter to be proved ["Nouvelles recherches sur l’hybridité", Nouv. Arch. Mus. Hist. Nat. 1 (1865): 25–176].
Will take earlier train to Down.
In response to CD’s request for bud-sports, he sends a piece of a fern-leaved beech.
