From J. D. Hooker   [24 June 1854]



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].

To J. D. Hooker   27 [June 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.

To Edward Sabine   28 June [1854]


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.

From J. D. Hooker   [29 June 1854]



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.
