Thanks JDH for his and Huxley’s countering of the false attack on George [Darwin] by Mivart. Encloses a note to Mivart on which he asks JDH’s opinion.
Questions on variation in nature: taxa varying in one region but not another. Variation between vs within species. Rarity of variation in important organs within a species. G. R. Waterhouse’s views on variation in highly developed organs, which CD relates to variation in rudimentary organs.
Asks for cases of obligate self-fertilising plants.
[CD annotation proposes using the Steudel Nomenclator botanicus (1821–4) to determine if variable species occur in genera with many species.]
Representative species may complicate tabulation of varieties.
Questions for Mr Anderson about horse colouring in Norway.
Has been writing an "audacious little discussion" to show that "organic beings are not perfect, only perfect enough to struggle with their competitors".
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.
Argument, based on geographical distribution and competition, for a mundane glacial period rather than cooling of one longitudinal belt at a time.
Pleased with news of BAAS meeting
and Scott’s possible position as Thomas Anderson’s curator.
Suggests Wallace is due for a Royal Medal.
Agrees with JDH’s criticism of Lyell’s address [see 4614].
Bentham’s Linnean Society address treats continuity of life in a vague non-natural sense.
Rereading his old MS [Natural selection] CD is impressed with work he had already done.
Writing Variation much harder than Climbing plants.
Encloses request to JDH to propose, or suggest on his behalf, that the Ray Society publish a translation of C. F. von Gärtner’s Versuche und Beobachtungen über die Bastarderzeugung im Pflanzenreich (1849).
A son [George Howard Darwin] was born on Wednesday.
Sends queries on Galapagos flora.
Discusses JDH’s comments on [Journal of researches].
CD feels that with his views on descent "really Nat. Hist. becomes a sublimely grand result-giving subject".
"How differently people view the same subject, for I look at insular Floras … as leading to an opposite view to yours."
Mourns death of Lyell. Wonders whether enough men of science were attached to him to raise a fitting testimonial.
Further response to MS of introductory essay to Flora Novae-Zelandiae.
Disbelieving in permanence of species has made little difference to CD in his barnacle work.
Edward Sabine’s official letter announcing CD’s receipt of Royal Society Medal left him cold. JDH’s informal one moved him.
Applauds JDH for supporting John Lindley.
Thanks JDH for dedication of Himalayan journals. CD praises the work and suggests stylistic revisions.
Lyell’s remarks on lava beds in letter from Madeira are not original – they refer exclusively to Élie de Beaumont’s data.
More praise for Himalayan journals.
How remote was glacial action in Himalayas?
Implies Himalayas were birthplace of many plants.
Final volume of Cirripedia to be printed in two or three months.
CD welcomes the prospect of the Philosophical Club of the Royal Society as means for seeing old acquaintances and making new ones. Will try to go up to London regularly.
Admits that the warning from JDH and Asa Gray (that more harm than good will come from combat over the species issue) makes him feel "deuced uncomfortable".
Reflects upon the complexity of Agassiz; how singular that a man of his eminence and immense knowledge "should write such wonderful stuff & bosh".
Has reread JDH’s paper ["On the functions of the rostellum of Listera ovata", Philos. Trans. R. Soc. Lond. 144 (1854): 259–64].
CD gives his definition of "highness" and "lowness" as "morphological differentiation" from a common embryo or archetype. JDH’s view, with which CD agrees when it can be applied, is the same as Milne-Edwards’, i.e., the physiological division of labour. There is little agreement among zoologists and CD admits his own lack of clarity.
CD "lectures" JDH on taking care of his health.
CD’s pleasure in London trip.
CD and Emma have taken season tickets to Crystal Palace.
Edward Forbes’s "Introductory Lecture" is the best CD ever read.
CD’s view requires only that ancient organisms resemble embryological stages of existing ones. Thus "highness" in plants is difficult to evaluate because they have no larval stages. Would compare highest members of two groups, rather than archetype, to determine which group was higher. Against Forbes’s polarity and parallelism.
On individuality.
Huxley’s review exquisite, but too severe on Vestiges; sorry for ridicule of Agassiz’s embryonic fishes.
Stonesfield mammals.
J. O. Westwood deserves Royal Society Medal.
Will begin species work in a few days.
Congratulates JDH on receipt of Royal Medal.
CD gathering facts on aberrant genera of insects.
