Undertakes to write geological part of Admiralty Instructions [A manual of scientific enquiry (1849), Collected papers 1: 227–50]. Has doubts as to his success.
Sends MS of his chapter on geology for Manual [Collected papers 1: 227–50]. Fears it may be too long. Does not much like it but can do no better. After hesitation, has recommended books. Defends his point that mere collection of rock specimens is "of hardly any use to Geology".
Sends MS of "Geology" for Manual [Collected papers 1: 227–50]. First parcel lost. Asks JFWH to give advice on an unclear note, translated from Élie de Beaumont, on measuring incline of lava-flows.
Describes colour changes from blue to red in valves of operculum of the cirripede genus Ibla.
Sends two valves of Ibla.
In his chapter [for Manual, Collected papers 1: 227–50], he will strike out any part that JFWH wants struck out, but if much shortening is required it will need rewriting.
Thanks JFWH for the trouble he has taken to correct printing error in "Geology".
Discusses Dr Gully’s water-cure.
As JH has accepted the superintendency of the Admiralty Manual he will try to undertake the geological part, but it will take time as he is busy on another project.
As JH is interested in colors he sends him details of the color changes that the genus Ibla undergoes. Will send him a specimen if desired.
Encloses samples of the Ibla. Outlines the method of making it change color. Hopes he will not have to re-write his geological chapter for the Admiralty Manual.
Has forwarded JH's note to Robert Mallet, who no doubt will compress his part. Encloses his own part,which he fears may be too long. Would like a chance to see the proofs. When completed would like several copies.
Sends his manuscript. P.O. has been unable to trace the missing parcel. Comments on J. B. Elie de Beaumont's method of measuring lava streams; emphasizes the importance of repeated observations. Would like copies of the manual when completed.
Thanks for his obliging note. Has already had one from John Murray. Hopes the Admiralty Manual will bear fruit. Has been at Malvern for three months and his health has improved enormously.
