Encloses 12s for the year.

Anxious for February number of the Journal.

F. J. Muñiz has offered fossil bones collected around Buenos Aires to the Royal College of Surgeons. He believes he can complete their Megatherium skeleton and provide other specimens. CD feels he should be encouraged in his work.

Concerning the purchase of shares.

If FJM wishes to sell the fossils he has discovered, CD suggests he appoint some agent to dispose of them.

Is surprised at the account of the earthquake in the pampas.

Offers to send his South America.

Greatly admires FJM’s zeal

and would welcome any information on the domestic animals of La Plata.

Can JDH come to 7 Park St. on Wednesday?

Asks to call on RC.

Notes on part of CD’s species sketch.

Maer purchase-money; London and Birmingham Railway Company shares.

Will come to 7 Park St. on Wednesday for a palaver on distribution, species mutability, migration, etc.

Illness has delayed his departure. Will try to call on JDH on Thursday.

Corrects a misunderstanding of his description of salt deposits [in South America, pp. 74–5]. The salt referred to was from Rio Negro, and was coarsely crystallised and free of other saline substances found in sea-salt. CD believes its lesser value in curing meat is owing to the absence of muriates of lime and magnesia and suggests that it might be worth while to add them to the Rio Negro salt.

Has received copy of CL’s Principles [7th ed.].

Comments on reading Annales des sciences naturelles.

David Milne’s and Robert Chambers’ views on Glen Roy.

Mentions sales of South America.

Memorial presented by members of the British Association for the Advancement of Science and other scientific societies, submitting that natural history is inadequately provided for by the present constitution of the Board of Trustees of the British Museum.

Thanks for JDH’s notes on species sketch. Proposes to drive to Kew to discuss them with him.

Honoured by GL’s review of Volcanic islands.

Sends copy [of South America].

Sends copy of South America.

Will consult BS’s article in the Bulletin.

Recommends article by Daniel Sharpe ["On slaty cleavage", J. Geol. Soc. Lond. 3 (1847): 74–105].

Cites his description of thin laminae in volcanic rocks in Volcanic islands. Suggests similar process may have affected metamorphic schists.

Thanks him for offer of his book [Lehrbuch der physikalischen Geographie und Geologie (1844–7)]. Since he reads German poorly, BS should send book only if short and inexpensive.

Health permitting, proposes to visit Kew on Friday.

Health bad, cannot get to Kew.

Will send Nulliporae to [L. A.?] Reeve.

JDH’s proposed India trip.

Will sorely miss discussions with JDH on species theory.

CD is getting on wretchedly with cirripedes.
