Summary

Is glad and proud to honour the memory of Adam Sedgwick [d. 1873].

Summary

Thanks for Études sur la coeur et la circulation centrale dans la série des vertébrés (Studies on the heart and the central circulation in the vertebrate series; Sabatier 1873).

Summary

Comments on BTL’s book [The philosophy of evolution (1873)].

"You are a bold man to speak in favour of pangenesis."

Summary

Thanks for Dionaea.

George Bentham’s last Linnean Society [Presidential] Address [Proc. Linn. Soc. Lond. (1873): viii–xxix]. Admires it greatly.

CD’s recent work leads him to a different theory [from GB’s] on the separation of the sexes of plants.

Huxley has been at Down working with CD on Drosera – very helpful.

Summary

Acknowledges CD’s cheque.

Sends CD cheque for profits on Orchids and a statement of stock on hand of CD’s works [missing].

Origin and Expression sales are stagnant.

Summary

H. W. Bates says CD is in town. WWR would like to call.

Summary

Fritz Müller is now working on the Brazilian honey-bees (Melipona and Trigona).

HM thanks CD for fertilisation references.

Summary

Has completed his book [The African sketch-book (1873)].

Summary

Sends results of his observations of cross- and self-fertilisation of Hypecoum grandiflorum and Eschscholzia californica [see Cross and self-fertilisation, pp. 331–2].

Summary

Asks for details about microscope parts.

Wants FD to ask Hooker for species of Desmodium; CD believes he has found new movements.

Also ask whether Hooker has Drosophyllum.

Summary

"The following fact with respect to the habits of ants, which I believe to be quite new, has been sent to me by a distinguished geologist, Mr J. D. Hague [see 8788]; and it appears well worth publishing."

Summary

Pleased that JC-B will review Expression.

Fears he will not be able to improve the book with JC-B’s "wonderfully curious" photographs because Murray printed such a large edition.

Would be glad to have JC-B’s notes on inheritance – "a most important subject".

Summary

Reports on insects fertilising Viola tricolor and on the fertilisation of the two wild forms [see Cross and self-fertilisation, p. 124 n., 125].

Summary

Will see whether formic acid delays germination of fresh seeds.

Thinks primer not at all a folly. Refers JDH to Asa Gray’s "child’s book" [see 8363].

Summary

HA’s paper on leaf arrangement is almost ready; asks CD to communicate it to the Royal Society. Seeks permission to quote from CD’s notes.

Summary

Discusses the arrangements being made to present a gift to Huxley [see 8872].

Summary

Observations on the leaves of Desmodium. Most are trifoliate; none has tendrils. Gives some comments from Hooker.

Summary

Thanks AD for kind review of Expression. AD’s remarks on necessity of tracing development of functions are novel and valuable.

Summary

Thanks for TE’s work on [Beroe?] with illustrations of its parts [Zoologische Studien auf Capri 1 (1873)].

Summary

CD thinks GHD’s letter is an excellent clarification [of CD’s conjectural view on the elimination of useless parts in species], but does not want to publish it as his [CD’s] own. Asks GHD to think carefully before he publishes it.
