Summary

Discusses cirripedes collected by JDD.

Gratified that he agrees "to some extent" with CD’s views on coral reefs.

Mentions his health.

Asks for JDD’s publication on cirripedes.

Sends message from William Baird concerning Crustacea research of J. O. Westwood.

Mentions Joseph Leidy’s discovery of cirripede eyes.

Summary

Thanks JDD for information.

Discusses Acasta sporillus.

Comments on review of first volume of Living Cirripedia [Am. J. Sci. 2d ser. 14 (1852): 125–7].

Asks JDD to examine Lerneidae.

Will read with interest the geographical discussion of Crustacea when JDD’s volume [Crustacea (1852–5)] appears. John Lubbock will purchase a copy.

Discusses error in Living Cirripedia.

Summary

In reply to CD’s query [see 2072], JDD describes what little is known about the crustacea of the Antarctic and southern lands.

Knows of no species of the cold temperate south identical with those of the cold temperate north.

Summary

Responds to JDD’s objections to his views on the three pairs of appendages in larvae of cirripedes. Reports observations which confirm his views.

Gives his confidential opinion of A. White, C. S. Bate, T. Bell, and W. Baird.

Interested in JDD’s observation that Crustacea are not most developed in the tropics. If JDD ever works it out either in number of species or rank, CD would be glad to have result.

Comments on article by Henri Milne-Edwards ["Crustacés", Ann. Sci. Nat. (Zool.) 18 (1852): 109–66].

Summary

On the colours of sexes in Crustacea; the structure of male crabs.

Summary

Wants CD’s advice on who would undertake describing the Crustacea from the Challenger expedition [1872–6].

Summary

Responds to CD’s criticism of his use of word "Kingdom" in discussing geographical distribution of Crustacea.

Summary

Thanks him for information concerning Crustacea.

Comments on natural history study in the U. S.

Mentions work done by Huxley on Crustacea ["Description of a new crustacean", J. Geol. Soc. Lond. 13 (1857): 363–9];

John Lubbock on larvae of Diptera.

Summary

He has gone through the whole embryology of the Crustacea and has arrived at a pretty well-established genealogy of the whole class; has even tried to write a history of the whole tribe. Finds he cannot adopt the old separation of Orders in the Class; the limits between them are indistinct.

Would like to study embryology of Limulus. Asks CD’s help in obtaining a female specimen.

Outlines his proposal to establish a marine zoological station.

Summary

Responds to CD’s query about the blind fauna of Mammoth Cave.

Gives information from L. Agassiz. Distribution of Crustacea, especially along southern coastlines.

Summary

Admires JDD’s work on Crustacea, corals, and geology.

Commends young John Lubbock to his attention. Hopes JDD can give him encouragement; if he can resist his "great wealth, business, and rank, he may do good work in Natural History".

Summary

Thanks for sending translation of A. W. Malm’s paper ["On flatfishes", K. Svensk. Vetensk. Akad. Handl. N. F. 7 (1867–8) no. 4]; thinks it establishes that eye migrates across surface of head rather than through the skull.

Considers the relationship between direction of locomotion and the presence of stalked eyes in Crustacea.

Summary

Discusses attachment of antennae in larvae of cirripedes.

Asks for information about how parasitic cirripedes are attached to host.

Summary

On structure of Crustacea; size of claws [see Descent 1: 330–1].
