JH was in Isle of Wight and did not receive dinner invitation. Apologizes for not coming. Asks when Mrs. Somerville's book [Mechanism of the Heavens] will be published.
Other engagements preclude JH from accepting JP's invitation to present a paper at the 'general Scientific meeting' [inaugural meeting of the B.A.A.S.] to be held at York.
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.
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.
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.
Notes that 36 Ophiuchi and 30 Scorpii have parallel proper motion; believes that James South overestimates the importance of this fact. Suggests double stars for WHS to observe.
Has correlated James Bradley's observations of the Castor and the Gamma Virginis double stars systems, which observations SR sent to JH, with later observations. Agreement is excellent. JH lays out elements of orbits for each system.
JH and Margaret arrived safely. Changes in town since 1826 visit. [Letter continues 19 Aug.:] Unable to find lodgings. Both babies [Caroline and Isabella] enjoy sea.
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.
Of isomorphic crystals and their varying behavior in response to heat, and of double stars.
Comments on a number of astronomical matters including double stars, awarding of medals, and on the elements of [Halley's] comet.
Remarks by JH on proof sheet of Henry Taylor's catalog of circumpolar stars observed by Stephen Groombridge. Why is Gerard Moll, a foreigner, engaged in purely English controversy? JH wants no part of Charles Babbage and James South in this matter. Regrets JH's earlier statements. Sends extract from [Richard] Copeland's letter.
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.
Is sending mirror in perfect state for Vincenzio Antinori at Florence, together with his letter. Regarding Gerard Moll's book. Has no time to spare to attend the [B.A.A.S.] meeting at York.
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.
No summary available.
Discusses feelings about offer of knighthood. Is ambivalent. Praises the Chancellor's [Henry Brougham's] interest in science.
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.]
Thanks WW for his favorable review of JH's Prelim. Discourse. Vernon Harcourt has asked JH for his views on the establishment of a B.A.A.S. Expresses some support but numerous reservations. Responds favorably to WW's suggestion that prominent scientists prepare surveys of their specialties for the meeting.
Is sending sketches, etc., from his field book made while visiting the Isle of Wight. Disagrees with some of WF's representations.
