Summary

Colour differences in annelids and entozoa.

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

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

Sends completed MS [vol. 1 of Living Cirripedia] with instructions for the printers; reviews number of plates and woodcuts, and offers to pay for extras and for excess corrections, if they occur. Hopes the Council [of the Ray Society] will print his second volume at the end of the ensuing year.

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

Comments on JL’s paper on Daphnia, ["An account of methods of reproduction in Daphnia and of the structure of the ephippium", Philos. Trans. R. Soc. Lond. 147 (1857): 79–100].

Summary

Finds he needs four woodcuts for the introduction [to vol. 1 of Living Cirripedia], which calls for quick action. Will send entire MS by the end of the month.

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

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

Requests HM’s article in the Witness [24 Feb 1855; see HM, "On the late severe frost", Proc. R. Phys. Soc. Edinburgh 1 (1854–8): 10–14], on the effects of frost on shells. CD expresses admiration for the two works by HM he has read.
