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.

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].
Has found a house on Baker Street to take for a month.
Mentions Daniel Sharpe’s study of the Grampians.
Association of various metamorphic rocks and relationship of their foliation to their dip and strike. Discusses foliation of schists and its origin. Comments on fluidity of gneiss and schists.
Relationship of schists to alternating beds of slate in western Tierra del Fuego and the Chonos Islands.
Comments on Sharpe’s theory of curved cleavage planes.
Example of metamorphosis in a "clay-slate porphyry region". Importance of previous lines of cleavage and stratification in foliation of metamorphosed rock.

Can AH give information about D. A. Godron, "De l’espèce et des races" [Mem. Soc. Sci. Lett. & Arts Nancy (1847): 182, 239–88]? CD unable to locate reference.
Thanks AH for seeking reference. If AH cannot find Godron [see 1648] it is hopeless. Thanks for reference to C. F. Hornschuch.
Mentions his paper ["Transportal of erratic boulders", Collected papers 1: 218–27]. Discusses ice-borne rock. Reference to unpublished paper on icebergs [?"Power of icebergs to make grooves", Collected papers 1: 252–5]. Remarks on scoring by icebergs. Comments on judgment of theories by Geological Society.

CD has more specimens of Helix pomatia.
Thanks for Lepidoptera book.
Invites JL to dinner.
Mentions RH’s book on light [Researches on light in its chemical relations, 2d ed. (1854)]. Asks about coloured glass used in experiments on plants.
Unable to give information on Mrs Shaw of Crayford.
