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.

CD returns home Saturday and would like his servant to take his MS [of Living Cirripedia] to Adlard that morning; he does not have a copy and would on no account re-undergo the labour he has spent on it.

Wants his MS [of Living Cirripedia] taken to Adlard by a trustworthy person and wants to be told when and how it was done; leaves a note for Adlard that he wants proof on the 17th or 18th.

G. B. Sowerby’s plates [for Living Cirripedia] are ready for the printer.

Thanks DS for writing about his research on foliation and cleavage. Discusses nature of slate and metamorphic schists.

Makes suggestions for the paper DS is preparing for the Royal Society and raises questions for his consideration; CD hopes he can attend the Society meeting when the paper is read ["On foliation and cleavage of Scotland", Philos. Trans. R. Soc. Lond. 142 (1852): 445–62].

Thanks GCH for Balanus specimens.

Ray Society has given CD 22 copies [of Living Cirripedia, vol. 1].

Returns Lake Superior [1850], which he already has received from Agassiz. Thanks for pamphlets by C. B. Adams [on Mollusca, Contrib. Conchol. 10 (1851): 189–206; 11 (1852): 207–15].

Describes his dissection of an unusual cirripede [Alcippe lampas] with 12 males attached [see Living Cirripedia 2: 556, 558].

Objects to early deadline for submitting manuscript [of Living Cirripedia 2 (1854)]. Discusses illustrations by G. B. Sowerby [Jr].

Volcanic activity of Mt Kilauea as described by Dana [Am. J. Sci. 2d ser. 9 (1850): 347–64]. Discusses the mechanics of volcanic eruption. Disputes view of William Hopkins that simultaneous action by volcanoes of different heights must come from separate lava sources. Notes relationship of continental elevation to volcanic action.

Thanks for specimens of cirripedes attached to rocks, which show no boring. CD hopes to see some on limestone.

Encourages CSB to do research on the complemental males of Scalpellum vulgare.

Discusses geological foliation and cleavage. Urges ACR to read CD’s remarks on subject in his South America before ACR publishes his paper ["On the lower Palaeozoic rocks", Q. J. Geol. Soc. Lond. 9 (1853): 161–79].

Discusses JAHdeB’s drawing of a Verruca.

Describes meeting of Geological Society [1 June 1853].

Mentions his criticism of Murchison’s lecture on flints.

Describes Robert Chambers’ "On the glacial phenomena in Scotland" [Edinburgh New Philos. J. 54 (1853): 229–82].

Mentions controversial election of members to the Royal Society.

Will quote CSB on discovery of Alcippe lampas.

Hopes CSB continues to look for Verruca on limestone.

Discusses use of CSB’s larvae illustrations [for Living Cirripedia].

Sends thanks for recent specimen, which gave him conclusive evidence that Verruca acts only on calcareous rocks.

Asks for a reference on carbonic acid.

Is glad CSB progresses in research on spider-like Crustacea.

Asks about source of paper on the metamorphosis of Pycnogonida for C. S. Bate.

Comments on CL’s plan to visit Tenerife.

Discusses inclination of strata on islands and around mountains.

Personal affairs of several scientists.

Visit by Henslow.

Notes publication by Hooker [Himalayan journals (1854)].

Asks JSH to inquire about drift-wood at Kerguelen Land.

Hooker’s observation on similarity of Kerguelen plant species to those of Tierra del Fuego strikes CD as a great anomaly, so he is searching for an answer, "however improbable".

Discusses views of Daniel Sharpe on foliation and cleavage. Recalls his own previous discussion [in South America].
