Summary

[Six fragments, mainly diagrams.] The geometry of bees’ cells.

Summary

Relates events at home;

hopes WED gets the scholarship.

Summary

Arranges meeting with JDH at Thatched House Tavern.

Eager for JDH’s reaction to MS on large and small genera.

Summary

Arrangements for JDH to visit Down for weekend.

Summary

CD’s health has been poor owing to hard work [on Natural selection]. He has to treat of every branch of natural history, which is beyond his strength.

Summary

Reports that N. J. Andersson finds every European willow bar one is also American.

Has heard from David Livingstone and reports on his progress.

Summary

Gives calculations on the structure of bees’ cells.

Summary

CD’s receipt of diploma from Caesarea Leopoldino-Carolina Academy [Dresden].

Summary

Hopes to begin pigeon MS in a week.

Has lately been working on bees’ cells and wishes very much to examine a cylindrical one.

Summary

Discusses bees’ cells. Wants hive and swarm; would be glad to have WBT’s box with commenced cells. "I am partly a disciple of Waterhouse, but not wholly."

Summary

Pleased with JDH’s reaction to MS on large and small genera.

Confident of soundness of principle of divergence.

CD experimenting on pollination mechanism of Leguminosae. Asks JDH to investigate Fumariaceae.

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

Acknowledges receipt of £242 11s. 10d.

Summary

Thanks for queen-bee larva and pupa.

Nervous system of Coccus.

Summary

Encloses MS by A. R. Wallace. CD has been forestalled. " . . . if Wallace had my MS sketch written out in 1842 he could not have made a better short abstract!" Wallace does not say if he wishes CD to publish MS, but CD will offer to send it to journal.

Summary

There is much weight in what RIM says about not breaking up the natural history collection of the British Museum. The botanical collection might be moved to Kew, but CD thinks "it would be the greatest evil which could possibly happen to natural science in this country if the other collections were ever to be removed from the British Museum and Library".

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

Thanks for hive.

Has started [writing up] pigeons and hopes to have finished with them in a week or two.
