Arrangements for foreign editions [of Expression]. Delay by Heliotype Company is provoking.

Thanks GH for his Theory of the ants [1869] and offers to supply any zoological information that he can.

Is sending Drosera back

and "the curious Kerguelen book".

"Drosera has almost been the death of me."

Hopes the accursed man [Ayrton] does not give JDH any more trouble.

Discusses JTM’s research on habits of insects. "How incomparably more valuable are such researches than the mere description of a thousand species."

Will consider JVC’s comments on Expression when he prepares a new edition.

Is much vexed about Drosera.

Land-level changes and volcanic activity.

Thanks for "Embryology of the fossil cephalopods", [Bull. Mus. Comp. Zool. Harvard 3 (1872–4): 59–112].

Regrets error in attributing acceleration concept to E. D. Cope instead of to AH in last edition of Origin, and misrepresentation of their joint view.

Discusses printing of Expression.

THF’s article in Nature ["The fertilisation of a few papilionaceous flowers", 6 (1872): 478–80, 498–501] is extremely good.

Suspects he now has answer to why common peas and sweetpeas hardly ever intercross, a point which half drove CD mad for years.

Thanks JVC for correcting his blunder on spelling of "Arrotino" [see Expression, p. 184]. "No Frenchman has a greater tendency to spell all proper names wrongly than I have."

Wants to make a present to her on the move to a new house.

CD would have been honoured to have EL translate forthcoming work [Expression], but J. V. Carus is already half way through this task.

Will let CIFM know [probably about John Murray’s terms for an Italian translation of Expression].

Thanks for information about hornless fossil Bos etruscus and Miocene fossils of genus Sus [see Descent, 2d ed., pp. 505, 521].

No summary available.

Remarks about an enclosed specimen,

and extract of letter from W. A. L. Marshall [8560].

ARW’s good review of J. C. Houzeau de Lehaie [Études sur les facultés mentales des animaux, in Nature 6 (1872): 469–71].

Spiralling of tendrils.

Has worked hard on Drosera.

Is interested in tracing the "nerves" of Dionaea which follow the vascular bundles. Finds he can paralyse half of the leaf by pricking it at a certain point.

Wishes AG to carry out two experiments on D. filiformis.

Has received AG’s Dubuque address [Am. J. Sci. 3d ser. 4 (1872): 282–98].

Condolences on death of JDH’s mother.

Supports the abolition of prize fellowships at the universities.

Discusses presentation copies of Expression.

Asks for London address of George King [Superintendent of Royal Botanic Garden, Calcutta], so he can ask about worm-castings sent by King from S. India. Has just received a splendid letter from John Scott on worms.

Asks where he can buy Dionaea.
