Recommends some changes in committee report being prepared that deals with the use to be made of the Royal Observatory's observational data.

Is advising Mr. R about a number of considerations to be taken into account while considering an invitation to apply for the position of Professor of Mathematics at the College of William and Mary in the United States.

Is very pleased with the results of WD's double star observations of Zeta Cancri, which William Stratford forwarded to JH.

Suggests an improvement in measuring techniques for astronomical observations, by making the angular measurement by direct and then reflected vision. JH wonders whether this idea might be appended to a paper currently under consideration by the R.A.S.

Discusses a variety of observations related to double stars, and asks FS to make some specific observations to compare with JH's work. Reveals JH's dream of going to the Southern Hemisphere for a number of years, but asks FS to keep it quiet, as 'many ties' stand in the way.

Comments with great satisfaction on WD's observations, and their close agreement with JH's for many of the same double stars.

A stiff and formal letter telling WF very clearly that JH fully agrees with the Newtonian system [as WF clearly does not], and that JH would not consider trying to apply pressure to the editors of philosophical magazines to publish WF's writings, in spite of threats from WF.

WF's manuscript, which JH returned with his letter of 1831-6-16, has not been received by WF. JH suggests some possibilities as to what might have happened, and deplores the tone of WF's letters, indicating that this tone causes JH to decline further correspondence on the subject.

Responds to TH's complaint that the government and the R.A.S. are not liberal enough with grants for science. JH rejects both complaints and explains why.

Explains to WM that in the present chaotic state of scientific responsibilities [the Board of Longitude has been abolished and the Royal Observatory at Greenwich's sphere of activity has been severely restricted], the Cape observations have not been published, but JH hopes that will soon occur. JH then asks WM to write when he arrives at the Cape, telling JH about the possibilities for an 'Amateur Observer' to live and observe at the Cape.

TH has been hurt by the tone of JH's letter [see JH's 1831-8-2] and felt he was writing to JH in confidence. JH assures TH that he has spoken to no one about any private details in TH's letter.

In reply to FB [see FB's 1831-8-25], JH believes that [Henry] Taylor, the person who had done all the reductions of the observations [Stephen] Groombridge's catalogue, should be asked to write the preface, both by reason of his familiarity with the material, as well as having earned the right to do so.

Favors concept of organization [B.A.A.S.] to guide scientific research and disseminate discoveries, but doubts that one is possible. Particular societies promoting special subjects are more likely to succeed. Anyone devoted to promoting such societies will have little time for research. Prefers to follow JH's own pursuits. Does not know James South's opinion.

Grieved to hear of Fearon Fallows broken state of health; in response to FB's request, JH reviews a number of possible candidates to succeed Fallows.

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.
