Summary

Returns books by Candolle and Robert Brown.

Summary

Examining JDH’s list. CD struck by how many plants are common to Europe, S. America, and Australia.

Summary

Hermaphrodite trees are enough to "knock" CD down. Can JDH observe Eucalyptus to see whether pollen and stigma mature at same time?

JDH’s facts showing European plants are more common in southern Australia than in South America are disturbing because they are improbable on CD’s views of migration.

JDH said he would give examples of Australian forms that have migrated north along the mountains of the Malay Archipelago.

Summary

Reports the decreased yield of pods resulting from excluding bees from the flowers of the kidney bean. Gives other observations suggesting the importance of bees in the fertilisation of papilionaceous flowers.

Cites cases of crosses between varieties of bean grown close together and requests observations from readers on the subject. States his belief "that is a law of nature that every organic being should occasionally be crossed with a different individual of the same species".

Summary

Asks LJ to lend him a copy of his paper ["Variation of species", Rep. BAAS 26 (1856): 101–5] and any notes or references he has. Although CD has a large accumulation of facts, it is impossible to see and consider too many.

His health is poor.

Summary

Fertilisation of papilionaceous flowers [Collected papers 2: 19–25].

JDH’s reactions to CD’s theory.

Discussed human fossil evidence with Hugh Falconer.

Summary

At work on the introductory essay to Flora Tasmaniae.

Discusses the effects of climate and geography on "vegetable strife".

Summary

Thanks LJ for his book [Observations in meteorology (1858)].

CD has been working on his species book [Natural selection].

Has become dreadfully heterodox on immutability of species.

His work on pigeons: variation under domestication throws the greatest light on variation in a state of nature.

Summary

Writing section on large and small genera [for Natural selection, ch. 4].

Huxley supersedes Owen on parthenogenesis.

Buckle’s History of civilisation in England extremely interesting.

Summary

Praises JDH’s Australian introduction.

Disputes JDH’s emphasis on SE. and SW. Australian flora.

Summary

An enclosure sent with the letter to JDH, 14 November [1858] (Correspondence vol. 7) - questions and comments on lists of European species found in south-west Australia and Tasmania, and European genera found in Australia.

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

CD has never doubted probability of Bering Strait land connection.

Family illness.

Summary

Expresses his strong opinion that Huxley’s paper ["Agamic reproduction and morphology of Aphis", Trans. Linn. Soc. Lond. 22 (1858): 193–220, 221–36] should be published.

Summary

Has gone over to CD’s side on the fertilisation of clover in New Zealand by bees.

Summary

Six volumes of Candolle’s Prodromus confirm rule that small genera vary less than large. Labiatae an exception to rule.

Summary

JDH wants papers at once. CD sends Wallace’s paper and CD’s abstract of his letter to Asa Gray. Sends [species] sketch of 1844 with JDH’s notes to assure JDH he had read it.

Summary

On papilionaceous flowers and CD’s theory that there are no eternal hermaphrodites. Connects this theory to absence of small-flowered legumes in New Zealand and the absence of small bees as pollinators.

Summary

Went to the show and saw EWVH’s birds.

Thinks he will give up his pigeons at the end of the summer.

Summary

[Copy of some rough notes.] References about species. Variations within species.
