Has received JDH’s book [Himalayan journals (1854)]. Is very gratified by the dedication to him.
Is relieved his book [Himalayan journals] has been well received and glad he has successfully completed it.
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.
JDH thanks Gray for his critique of one of JDH's papers. JDH knows he is a difficult person when it comes to criticism. He mentions the issue of defining species & the significance of genetic resemblance & explains that he & Thomas Thomson have touched on the subject in the introduction to the FLORA INDICA. This long introduction will also include an account of the history of Indian botany, an essay on the climate & geographical account of the provinces. JDH is distributing & naming his Indian plants & laments the lack of standard nomenclature. He is currently working on Antidesmas with reference to Tulasne's paper, which is imperfect because of the shortcomings in the French collections he consulted. He mentions the difficulty in pinning down the characteristics of wild & cultivated Yew. JDH has taken a house on Kew Green for George Bentham, near William Jackson Hooker's herbarium in Hanover House. The herbarium now has a curator. Sometimes JDH thinks of abandoning Kew to write for the press in London, he finds it hard to support his growing family on a government salary whilst living in expensive Kew. JDH's father WJH is trying to secure JDH's continued employment for the Office of Woods & Forests but JDH is not optimistic. JDH stays at Kew to please his father & to have access to his herbarium & library. Nathaniel Wallich is very ill, Brown better at present. The Van Diemen's Land [Tasmania] Government have purchased 6 copies of JDH's forthcoming FLORA TASMANIAE & the income is welcome as he made no money from his Antarctic expedition southern floras. JDH describes his recent work on fossil plants, especially Trigonocarpi from coal formations, they resemble Salisburia. JDH outlines his responsibilities regarding scientific societies, he is on the council of the Royal, Linnean & Geographical societies. He has managed to secure a review of the state of the Linnean Society botanical collections. Mentions Caspar Georg Carl Reinwardt is dead at Leyden [Leiden].
JDH summarises letter from Humboldt.

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".
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.
Birth of JDH’s second child.
Asks CD’s view of "highness" and "lowness" in animals. Gives his own for plants; extent of deviation from type, e.g., floral parts deviating from leaf.
Reading B. C. Brodie’s Psychological inquiries [1854].
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.
JDH on "highness" of Coniferae: they are genuine Dicotyledons, not a link to cryptogams; that is a geologists’ fallacy. Thus they are highest plants in Carboniferous.
Does not agree with CD’s "elastic" species theory. Long correspondence with Lyell on this.
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.

JDH and F. W. Binney identify Calamites specimens as pith casts. They are cryptogams related to, but higher than, Lycopodiaceae and contradict progression.
Insects found in coal.
Lyell says Stonesfield slate marsupials are actually placentals.
JDH reading Alexander Braun on individuality ["Das Individuum der Pflanze in seinem Verhältniss zur Species", Abh. K. Akad. Wiss. Berlin (Phys. Kl.) (1853): 19–122].

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.
