CD gathering facts on aberrant genera of insects.
Regrets he cannot come to hear DS’s paper ["On the structure of Mont Blanc", Q. J. Geol. Soc. Lond. 11 (1855): 11–27]. Has a lively interest in the subject.
Edward Forbes has misrepresented his view on foliation and cleavage [Athenæum 30 Sept 1854].
CD is convinced DS’s view will replace Huttonian and Lyellian view of metamorphic schists.
Recommends H. C. Sorby’s paper [probably "On the origin of slaty cleavage", Edinburgh New Philos. J. 55 (1853): 137–50].
Calculating small number of species in aberrant genera of insects and plants.
Joachim Barrande’s "Colonies", Élie de Beaumont’s "lines of Elevation", Forbes’s "Polarity" make CD despair, as these theories lead to conclusions opposite to CD’s from the same classes of facts.
Asks JSH to inquire about drift-wood at Kerguelen Land.
Hooker’s observation on similarity of Kerguelen plant species to those of Tierra del Fuego strikes CD as a great anomaly, so he is searching for an answer, "however improbable".
Requests authoritative information on erratic boulders and marks of glaciers in New Zealand, and especially in southern islands.
Grief at the death of Edward Forbes.
