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.

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

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.

CD has two corrections in spelling on woodcut [for Fossil Cirripedia (Lepadidae)]. Has asked J. S. Bowerbank who should cut the blocks and suggested JdeCS get it done. Repeats arrangements to compare specimens and proofs in London.

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 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.

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.

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