Continued objections to methods and conclusions of CD’s survey.

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.

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.

Replies at length to JDH’s worried reaction to his comments on lowness of Australian plants. CD distinguishes between "competitive highness", i.e., which fauna would be exterminated and which survive if two faunas were placed in competition, and ordinary "highness" of classification.

Sends record of pigeon flight from London to Antwerp. [Lord W. Lennox, Merrie England (1857), p. 185.]

Extracts from MS of vol. 4 of HCW’s Cybele Britannica [1847–59] showing the diversity of views on species among botanists.

Calculations relating to bees’ cells.

Discusses the ranges and distribution of varieties relative to the type species.

Zebra-striped asses.

Markings of a Bengal jungle cock.

Refers to some of his own articles on birds in India.

Reports the arrival of the "glorious garrison of Lucknow". The "wonderful superiority of the European to the Asiatic" made the success of the insurrection inconceivable.

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.

CD has never doubted probability of Bering Strait land connection.

Family illness.

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

Mrs Henslow’s death stirs reminiscences of happier days.

General success of survey makes CD very concerned about sources of error. Wants to meet JDH for an important talk about big genera. Arranges meeting.

Returns books by Candolle and Robert Brown.

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

Bees’ cells. Observations on Osmia atricapilla.

Describes some species of fauna peculiar to Fernando Po. The ocean currents make it unlikely that animals have been floated to the little islands [off the west coast of Africa].

Writes of domestic matters

and asks WED to observe cart-horses for traces of dark stripes on spine and cross-stripes on shoulder.

GRW’s observations of and ideas on bees’ and wasps’ cells.
