Urges RM to read The Times for the previous day.

Thanks RM for information RM sent on fossils. JH's brother-in-law, due to an accident, has, however, ended geological investigations.

Gives permission for publication of JH's paper ['On the Astronomical Causes Which May Influence Geological Phenomena'] in Geological Society's Transactions. Mentions report of a giant fossil found in United States.

Writes to inform RM of the arrival of Mr. Simonoff, director of the astronomical and magnetic observatory of Kasan, and indicates Mr. Simonoff's likely interests.

Attempts explanation of curious subterranean acoustic phenomenon at Nakoos. Explains other natural acoustic phenomena and eruptions of geysers in Iceland. P.S.: Do not nominate JH to council of Geological Society.

Unsatisfied with H. W. Pickersgill as the person to paint JH's portrait. JH wants to consider further what to do.

Wishes to nominate Mr. Hardin [?], who has written on Indian geology, for membership in the Geological Society.

Describes various geological aspects of the Cape area and mentions JH's astronomical work. Regrets that RM's brother is leaving the Cape.

Some geological samples have been lost on the way to England; JH comments on his ideas of the effect of the earth's hot core on the construction of the earth's crust.

Has read RM's note to the Morning Post correcting error in the report on the dinner [in JH's honor]. Wishes money had not been mentioned in RM's reply. Is grateful for all RM's work in arranging for the dinner.

Writes in great haste, thanking RM on behalf of Lady Herschel for taking 'trouble,' especially for 'Literary Tributes' apparently sent for Lady H's album.

Glad to see RM's geological labors on The Silurian System completed.

Declines RM's request that JH become a candidate for Oxford's Savilian Professorship [see RM's 1839-3-27]. JH plans to move farther from London.

Did not vote for RM's friend at the R.S.L. because JH missed the meeting. JH will also miss the next meeting of the Geological Society, as he is returning to Collingwood.

Offers an explanation of the phenomena of the freezing cave of Illetzkaya Zatchita in Russia.

On RM's stepping down as president of Geological Society. Where exactly abroad will RM pursue enquiries?

Responds to RM's request for an analysis of the cause of the difference in climate between Orenburg and Catherineburg in Russia. Agrees that Geological Society can print JH's Alpine memoir.

Willing to chair B.A.A.S. meeting next year, provided no other duties are imposed on JH's time and that no one else desires that office.

Appreciates foresight, but cannot commit to be president of B.A.A.S. meeting at Cambridge in summer of 1846. Date is too far away; personal and domestic commitments are pressing.

Can raise no objections to being president of the B.A.A.S. for 1845, but will be unable to be in York this year.
