Summary

He has returned William Thompson’s MSS and, he believes, all his specimens of Cirripedia.

Summary

Discusses his investments.

Summary

Is honoured by his election to the Philosophical Club [of the Royal Society].

Summary

About share transfers, involving JW as a trustee of CD/Emma marriage trust.

Summary

CD expresses his inability to accept the view that the Hippuritidae are in any way a connecting link between the oysters and the barnacles.

Summary

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].

Summary

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.

Summary

Is unequal to taking chair as President of Natural History Section of BAAS meeting in Liverpool. Very little fatigue or excitement brings on swimming of head, nausea, and other symptoms.

Summary

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.

Summary

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.

Summary

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.

Summary

Thanks for money paid into his account. Has not received interest payment from Lord Powis.

Summary

Thanks JAHdeB for his present of two volumes [Description des Entomostracés fossiles des terrains tertiaires de la France et de la Belgique (1852) and "Les Crustacés fossiles du Limbourg" (1854)]. CD was interested in the remarks on geographical distribution of the Entomostraca.

CD’s second volume for the Ray Society [Living Cirripedia] is finished but not yet published.

Summary

Should like to examine the correspondent’s Madeira cirripedes but is too much occupied with other subjects of natural history.

Summary

Has found a half dozen [cirripede] specimens belonging to William Thompson and a few MS notes. Asks for instructions for sending them to RP.

Summary

Arranges to return a collection of cirripedes which belongs to her husband [Samuel Stutchbury].

Summary

Can AH spare Alcippe specimens for British Museum?

C. S. Bate has found Alcippe off Plymouth.

Discusses returning specimens to AH.

Owes to AH the discussion of powers of excavation of Verruca in Living Cirripedia [vol. 2 (1854)].

Summary

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].

Summary

Discusses specimen of Balanus crenatus.

Sorry JP’s children are ill.

Will come to Liverpool if well [for meeting of BAAS].

Summary

Sends fossil cirripedes for the museum’s collection.
