Summary

Thanks JWF and G. R. Waterhouse for cirripede specimens.

Summary

Discusses illustrations [for Living Cirripedia 1 (1851)]. Mentions drawings by G. B. Sowerby [Jr].

Summary

Thanks him for cirripede specimens. Discusses RF’s collection.

Summary

Describes progress of research on fossil cirripedes. Comments on specimens sent by JS. Asks about age of several European formations, and for information about specimens.

Summary

Thanks SPW for his history of Aptychus, which makes A. D. d’Orbigny’s view [that it is a cirripede] improbable. [See Fossil Cirripedia 1: 3.]

Specimens SPW sent are very useful and interesting.

Summary

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.

Summary

Regrets delay in sending pamphlets for JDD.

Thanks him for information concerning cirripedes.

Sends thanks to Charles Pickering for information about plant distribution.

Discusses boring species of cirripedes.

Believes Harry D. S. Goodsir mistaken about parasites on Balanus ["Observations on organs of generation in Crustacea", Edinburgh New Philos. J. 36 (1843–4): 183–6]. In fact parasites are the males of the species.

Summary

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.

Summary

Has not completed description of NTW’s Loricula. Wants permission to have it figured by James de Carle Sowerby. Does NTW have other fossil cirripedes?

Summary

Has received plates. Gives instructions for scale and arrangement of engravings.

Summary

Reports on the fossil cirripedes sent him; several are new, some are "elegant".

Summary

Gives his opinion that the larval antennae in Lepas correspond with the inferior antennae, the superior not present, as in most Daphnidae. [See 1381.]

Summary

Discusses woodcut illustrations [for Fossil Cirripedia, vol. 1]. Wants species descriptions to be in both Latin and English.

Summary

Thanks for fossil cirripede specimens.

Describes progress on his book [Fossil Cirripedia] and his work on living cirripedes. Asks to borrow specimens.

Comments on book [F. C. L. Koch and Wilhelm Dunker, Norddeutschen Oolithgebildes (1837)].

Sends thanks to Friedrich Adolph Roemer and R. A. Philippi for specimens.

Summary

Thanks JS for fossil cirripedes. Discusses the specimens. Sends thanks to J. G. Forchhammer for specimens.

Summary

Has sent G. B. Sowerby Jr some skeleton plates [for vol. 1 of Living Cirripedia] which the Council [of the Ray Society] may also wish to see, along with GBS’s finished drawings. He reminds EL that he has not heard about colour for the plates and adds he has not been told what type should be used; gives estimated lengths of part 1 in different sizes of type (part 2 will be fully twice the size of this). Hopes if the Council does not publish part 1 in 1851 it will publish all in 1852.

Summary

Explains that he is working on recent and fossil Cirripedia, and asks if WD can aid him with specimens of Roemer’s Pollicipes species.

Summary

Discusses fossil cirripede specimens from RF’s collection. Comments on problems of describing their valves.

Summary

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].

Summary

Has lost a good many days and will need another fortnight to finish the pedunculate fossil cirripedes. The Palaeontographical Society will publish the fossil species. "If I was but better in health, I shd work quicker."
