Summary

Gives calculations on the structure of bees’ cells.

Summary

Encloses projections and models relating to geometry of bees’ cells.

Summary

Sends a model of bee cells "as bad as a Chinese puzzle". [A series of paper cut-out figures.]

Summary

Thanks for queen-bee larva and pupa.

Nervous system of Coccus.

Summary

Discusses geometry related to the structure of bees’ cells. Encloses notes and diagrams dealing with intersections of spheres.

Summary

Self-fertilisation in Fumariaceae.

[CD note on bees’ visiting some members of Fumariaceae.]

Summary

Sends proofs [of "On the tendency of species to form varieties … ", read 1 July 1858, Collected papers 2: 3–19]. CD could publish his abstract [later the Origin] as a separate supplemental number of [Journal of the Linnean Society].

JDH has studied in detail CD’s manuscript on variable species in large and small genera and concurs with its consequences. Discusses methodological idiosyncrasies of systematists, e.g., Bentham, Robert Brown, and C. C. Babington, which complicate CD’s tabulations.

Summary

Discusses the absence of a native bee in New Zealand and the insects which probably performed its fertilising function [see "Agency of bees in fertilization", Collected papers 2: 21]. Describes the success of the naturalised hive-bee and also the rapid spread of introduced members of the Fabaceae.

Summary

The CD–Wallace paper has gone to press.

JDH’s tabulation of variable species from Bentham was done in haste.

Summary

Bees’ cells; is the hexagonal shape deliberate or merely the result of lateral pressure on cylinders?

Summary

Encloses a list of British perennials which seed in New South Wales and explains the source of his information. Lists plants which have become weeds in the country.

Summary

Cannot explain impurity of his alleged pure lines.

Summary

Sends more bean seeds.

Summary

Answers CD’s queries about seed lot he has just sent.

Summary

Has examined feet of many partridges, but has not been able to obtain any quantity of mud from them.

Summary

Further answers on his seed lot.

Summary

Information about about Kattywar (Kathiawari) horses in India.

Summary

Further information about about Kattywar (Kathiawari) horses in India.

Summary

Busy with introductory essay to [The botany of the Antarctic voyage, pt III] Flora Tasmaniae [printed separately as On the flora of Australia (1859)].

Now explains greater abundance of European species in Tasmania than in Fuegia by CD’s "refrigeration" hypothesis.
