Discusses depths at which ripple-marks appear on sea-floor.
Personal and social comment.
Mentions receiving Agassiz’s Lake Superior [1850].
CD is pleased with the drawings for Fossil Cirripedia but wants a few corrections which he would like very soon.
On Himalayan stratigraphy. Believes JDH’s observations of glacial action are the first ever done east of Urals.
Barnacles and the species theory; impressed with variation.
Effect of CD’s species sketch on JDH’s view of willow systematics.
Thanks CSB for drawings of [cirripede] larva and for permission to cite unpublished paper ["On the development of the cirripedes", Ann. & Mag. Nat. Hist. 2d ser. 8 (1851): 324–32]. Describes method of preserving specimens. Mentions Balanus common on tidal rocks at Tenby.
Thanks LA for presentation copy of his book, Lake Superior [1850].
Comments on species of cirripedes sent by LA and A. A. Gould.
Asks him to send additional cirripede specimens.
Has received plates. Gives instructions for scale and arrangement of engravings.
An enquiry about the availability, size, and cost of cork-lined boxes for entomological collections.
Reports on the fossil cirripedes sent him; several are new, some are "elegant".
Thanks CSB for cirripede larvae.
Has been unwell.
Cannot see transverse articulation referred to and does not believe in it.
Sends species synonyms.
Discussion of Chthamalinae.
Suggests using asphalt to seal specimen containers.
Comments on mouth of larva.
CD asks for the return of a specimen [to be used for illustration in Fossil Cirripedia (Lepadidae)], so he can do some identifying.
J. S. Bowerbank has again asked on behalf of the Palaeontographical Society what progress has been made.
Returns one figure and sends two minute new species to be figured [for Fossil Cirripedia (Lepadidae)]. "Pray observe how time slips by."
CD insistently requests JdeCS to have all rough illustrations [for Fossil Cirripedia (Lepadidae)] done in time for next Council meeting of the Palaeontographical Society.
CD has received an enormous lot of Scanian and Copenhagen cirripede fossils, some of which he thinks may be better than those sent to JdeCS earlier; asks him to delay engraving foreign specimens until CD has time to go through the new lot.
Fossil cirripede specimens have arrived.
Describes progress on his monograph [Fossil Cirripedia].
Would be grateful for the paper on Lithotrya. Asks for information.
Has heard that Louis Agassiz maintains the doctrine of several species of man "much I daresay to the comfort of the slave-holding southerners".
Homeopathy excites his wrath even more than clairvoyance.
New specimens have shown CD he has two distinct species under one name [in Fossil Cirripedia (Lepadidae)]. He adds new figures and suggests deletions. Will come to London when he has proofs.
About to go to press with "wearyful" Fossil Cirripedia [vol. 1 (1851)];
would like to borrow proof-sheets of Frederick Dixon’s work [The geology and fossils of the Tertiary and Cretaceous formations of Sussex (1850)]. Would also like to borrow a specimen of Balanus glacialis from Royal College of Surgeons. Encloses formal request [see 1356].
Asks to borrow specimen of Balanus glacialis from the Museum of the Royal College of Surgeons. It will be necessary to disarticulate it, but CD will return the valves to the Museum.
