Hopes Richard Owen will have time to do CD’s shells in spirits.
Doubts WJB’s suggestion that moles may play a part in formation of mould.
Has enjoyed reading LA’s book [Études sur les glaciers (1840)].
Hopes LA will pardon manner in which CD has alluded to his work on glaciers in his Journal of researches, of which he sends a copy.
[Excerpt copied from a letter CD wrote to WHF.]
CD’s gratefulness to William Buckland for his guidance on the glaciated terrain of N. Wales. "I am also convinced that the valleys of Glen Roy … have been occupied by arms of the Sea, & very likely, (for on that point I cannot of course doubt Agassiz & Buckland) by glaciers also."
Asks for a meeting in order to go over the shells [which GBS was to describe in the appendix on Tertiary fossil shells in South America].
Encloses letter and paper to be forwarded to B. J. Sulivan.
Apologises for length of notes of advice for microscopic work.
Describes his research on cirripedes. Asks to borrow specimens. Comments on previous work on the subject.
Thanks for note and enclosure. Has written to [David?] Landsborough to say dried specimen was just what he wanted. Would like some more in spirits.
Very unwell.
Thanks LA and sends thanks to A. A. Gould for specimens. Describes principal findings of his research on cirripedes. Is obliged for information Joseph Leidy gave about cirripede eyes. Describes anatomical features and chief aspects of growth. Describes discovery of parasitic males and a species parasitic upon other cirripedes.
CD proposes to call for tea if he is well enough on Thursday.
Thanks J. D. Dana for cirripede specimens. Describes his work. Comments on Ibla. Would like to see AAG’s notes and figures on Anatifa. Asks for references to cirripede descriptions by T. A. Conrad.
Parcel from AAG containing cirripede specimens has been received by CD from Hugh Cuming.
Thanks LA for presentation copy of his book, Lake Superior [1850].
Comments on species of cirripedes sent by LA and A. A. Gould.
Asks to re-examine specimen of Scalpellum. Discusses publication [of Fossil Cirripedia] by Palaeontographical Society.
