From J. D. Hooker [24 June 1854]
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].

From J. D. Hooker [29 June 1854]
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.
