Asks whether CD has any observations to make on J. R. L. Delboeuf’s article ["Les mathématiques et la transformisme"] in Revue Scientifique [2d ser. 29 (1877): 669–79]. He would be pleased to receive a letter or article for publication.

Has not seen Delboeuf’s article [see 10786] and would be obliged for a copy. He is not likely to have any comments as he is engaged in other work.

Believes CD is in error in his notice on the scarcity of holly berries [Collected papers 2: 189–90] in asserting that holly is not a hermaphrodite.

At Asa Gray’s request, writes what he knows about Pontederia cordata.

Reply to CD’s note ["Holly berries", Collected papers 2: 189–90] from a beekeeper: attributes the scarcity of bees to the harshness of weather in preceding spring.

Thanks for essays ["Das Aufschiessen der Runkelrüben", Landwirtsch. Jahrb. Berlin 5 (1876): 31–45; "Die Züchtung neuer Getreide Varietäten", ibid 6 (1877): 193–233]. Surprised about Beta vulgaris.

CD has only a trifling point to make in criticism [of RLT’s excerpt from Diseases of women]: he believes "the high value of well-bred males is due to their transmitting their good qualities to a far greater number of offspring than can the female".

Thanks for new edition of Orchids.

The remarkable papers of Mott on Ernst Haeckel ["On Haeckel’s history of creation", Proc. Lit. & Philos. Soc. Liverpool 31 (1876–7): 41–89].

Praise for Cross and self-fertilisation: most important point proved is benefit of crossing between related individuals grown under different conditions. This explains adaptive value of dispersal mechanisms.

Has observed the scarcity of humble-bees and subsequently of holly berries this year. But does not think humble-bees ever visit holly flowers, however plentiful they may be.

Thanks for CD’s frank criticism of his views.
