Has gone over to CD’s side on the fertilisation of clover in New Zealand by bees.
Botanical practice can confuse CD’s compilations. Many small genera would have been species had the whole natural order [family] been known.
JDH’s low opinion of Buckle;
high opinion of Mrs Farrer.
Summary of JDH’s objections to CD’s survey of floras and conclusion that large genera vary more than small.
Continued objections to methods and conclusions of CD’s survey.
Reports that N. J. Andersson finds every European willow bar one is also American.
Has heard from David Livingstone and reports on his progress.
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.
The CD–Wallace paper has gone to press.
JDH’s tabulation of variable species from Bentham was done in haste.
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.
At work on the introductory essay to Flora Tasmaniae.
Discusses the effects of climate and geography on "vegetable strife".
Would appreciate loan of CD’s chapter on transmigration across tropics, which may help with the difficulties of Australian distribution.
Still regards plant types as older than animal types.
The Cape of Good Hope and Australian temperate floras cannot be connected by the highlands of Abyssinia.
JDH cannot abide CD’s connection of wide-ranging species and "highness". Australian flora contradicts this in many ways.
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.
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.
Fertilisation of clover by bees in New Zealand.
Uneasy about biggest genera and their varieties.
H. T. Buckle’s sophistry [History of civilisation in England (1857)].
Working on bees’ cells.
JDH has confirmed CD’s opinion on the affinities of species in great genera. Is looking at large genera in several local Floras to find the "range & commonness of varying species".
Has been "beyond measure interested" in the construction instincts of the hive-bee.
C. C. Babington agrees with JDH that botanists tend to note varieties more in large genera than in very small ones.
Heartened that tabulations of small and large genera done in different ways yield good results. JDH has done some tabulations but has not followed CD’s method of getting equal numbers of small and large genera.
