Thanks for his books. Encloses one of his own pamphlets on Atoms, which will show his personal view of mind versus matter. Comments on some of Haig's terminology.

Still relating to the manuscript of WF's not yet returned to him [see JH's 1831-7-28], JH explains very carefully how it was sent back and where WF should look for it. [Correspondence books contain a shorter version, partly torn out.]

Was pleased to receive his letter and comments on his book (Prelim. Discourse). Much of the book was written in great haste, but will bear his comments in mind should a new edition be required.

Gives a reply to the query on life assurance, but is not clear what the question is really about. Is flattered by the suggestion for a passage to the Cape in a Naval vessel, but has made up his mind to travel privately.

Expresses JH's preferences with respect to the appointment of the Cape Observatory astronomer in terms of the choices available [Follow-up letter to JH's 1831-9-13].

Is grateful for BH's interest over the matter of travel to the Cape. Gives his own views on the intentions of Sir James Graham. Intends to see Graham personally and thank him for his interest.

Provides detailed observations made by JH on his ascent up Monte Rosa in the Alps.

Writes asking that James Grahame's father-in-law, Rev. Wilson, be retained as pastor of the Protestant church at Nantes.

Returns his packet of papers together with the letters of M. J. P. Flourens, [J. P.?] Müller, etc. Does not feel competent to judge papers such as MH's, which lie outside his field of knowledge. Should rid his mind of bias on the part of Council. Submit papers as from himself.

Pressure of business prevented him from replying earlier. Reserves his advice for matters that fall within his own researches. Thinks it would be advisable to obtain the opinions of several competent Fellows, not on the Council.

Thanks GB for the gift of a work on medicine, and then JH proceeds to comment at some length on various aspects contained in it.

Thanks for the offer of 25 copies of the Admiralty Manual. Thinks contributors should receive 6 copies instead of the 2 copies originally intended. Some misunderstanding of his proposals regarding returns of information. Printer has made a blunder in the Manual and JH has given orders for new pages to be substituted.

In an article commenting on a pamphlet about the alleged decline of science in England, JH's name has frequently been taken in vain. JH writes to protest.

Asks that in JD's lectures at King's College, London, he remove an unfair and incorrect reference to JH.

Wants to ensure that a letter of JH's on the decline of science controversy is to be published in Brewster's journal.

About the solution of algebraic equations and JH's previous work on this topic.

Comments on analytic symbolism in mathematics.

Thanks JD for his letter [see JD's 1831-11-26].

Expresses thanks for RH, in a paper on George Boole in the British Quarterly Review, giving JH credit for having published 'my introduction of the mode of separation of the symbol of differentiation from the differentiated function and executing on it operations analogous to those of common algebra.'

Having now learned that the offensive article in the Edinburgh Review was by DB [see DB's 1831-12-1], JH writes in surprise that DB could have written what he did, and requests that JH's letter [see JH's 1831-11-25] be returned unpublished. JH will decide how to proceed.
