Because of health, CD will postpone coming to London until all drawings are finished.

Asks JdeCS, if he is able "with any honesty", to "purloin" for him a proof-sheet of Frederick Dixon’s plate with cirripedes [in Geology and fossils … of Sussex (1850)].

Requests statement of total owed to JdeCS as a guide to the future.

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."

The Palaeontographical Society will give him only one plate for foreign species. Work should stop until he knows how many will fit in. He must know what progress has been made.

Urges dispatch on illustrations [for Fossil Cirripedia]; CD’s MS has been ready for some time and all depends on JdeCS. Suggests a way to hasten progress.

CD wants Lepadidae drawings [for Fossil Cirripedia] harder, with lines of growth more distinct; he wants no shading or similarity to lithography, which he thinks has harmed natural history. He realises that mutilated specimens may make accuracy difficult.

CD is pleased with the drawings for Fossil Cirripedia but wants a few corrections which he would like very soon.

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

CD asks for the return of a specimen [to be used for illustration in Fossil Cirripedia (Lepadidae)], so he can do some identifying.

J. S. Bowerbank has again asked on behalf of the Palaeontographical Society what progress has been made.

Returns one figure and sends two minute new species to be figured [for Fossil Cirripedia (Lepadidae)]. "Pray observe how time slips by."

CD insistently requests JdeCS to have all rough illustrations [for Fossil Cirripedia (Lepadidae)] done in time for next Council meeting of the Palaeontographical Society.

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.

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 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.

CD is pleased with plates [for Fossil Cirripedia (Lepadidae)]; most corrections need only a touch. Requests revises soon and asks how much he owes.

CD likes the plates [for Fossil Cirripedia (Lepadidae)] except pl. I [Scalpellum], which calls for several revisions; he sees that not all corrections were made, but assumes they called for too extensive changes.

CD appreciates JdeCS’s care. Sends specimens, noting points to be observed. He adds that the figures which have been most troublesome are those of which drawings were made [for Fossil Cirripedia (Lepadidae)].

Comments on JdeCS’s plates [for Fossil Cirripedia (Lepadidae)]. Asks if JdeCS can lend him specimens of fossil Balanidae.
