Plans to come to London to examine the proofs of JdeCS’s plates [for Fossil Cirripedia (Lepadidae)]. Has new German specimens; one is unknown and must be introduced but a woodblock will do.

CD likes the engravings [for Fossil Cirripedia (Lepadidae)] but is distressed by JdeCS’s slow progress and is being pressed by owners to return their specimens.

Sends thanks for a note and returned drawing.

He is sending more text.

Expresses sympathy to MSH on W. J. Hooker’s illness.

Will send his comments on Hodgson’s physico-geographical memoir ["On the physical geography of the Himalayas", J. Asiat. Soc. Bengal 18 (1849): 761–88] directly to him.

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

CD will write again when he returns to Down and has looked over his MS.

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.

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