Has examined Edward Sabine's transit measurements; finds them unproblematic.

Has represented JS's interests as best JH can regarding JS's proposal. Describes himself as unskillful in such representations.

Defends Edward Sabine's transit observations, noting that JH supports them on practical rather than theoretical grounds.

Making, reducing, and publishing double star work is very difficult and, because of Wilhelm Struve's recent endeavors, less pressing than it had been. Mentions various doubles. Expresses interest in JS's plan to purchase a very large refractor.

Agrees to purchase JS's 7-foot refractor if no other reasonable offer made, but doubts he would use it extensively. Plans to concentrate on observing nebulae with JH's reflector at Slough. Relays regards and question for P. S. Laplace.

Has received materials sent by JS. Printing of paper by JS and JH on double stars is nearly completed. Urges that the issue is not whether the observations of 70 Ophiuchi made by Wilhelm Struve are better than those made by JH and JS; the issue is truth. Caroline Herschel has sent to JH a catalogue of his father's observation. Busy observing nebulae.

JH's attempts with Edward Sabine to measure the difference in longitude between Greenwich and the Paris Observatory. Supplies, for Alexander von Humboldt, JH's measurement of Mount Etna's height. Gives message for François Arago concerning paper on magnetism published by JH and Charles Babbage.

Asks JS to check over and forward to Astronomische Nachrichten JH's paper ['Letter on Fraunhofer's Claims for the Inferiority of Reflecting as Compared to Refracting Telescopes'], which paper calls attentions to errors in the catalogue of double stars published by JS and JH.

R.S.L. Council will meet 17 Nov. to discuss awarding its Copley medal; hence JS's paper, to be presented to R.S.L. later that day, cannot be considered for the award. Other matters have prevented JH from preparing annotations of JS's latest paper on double stars.

Looked for JS to talk with him about the secretaryship of the R.S.L., specifically discussing Charles Babbage's position. JH would prefer to have JS nominate Babbage.

Urges JS not to insist on a minor point of dispute about the title of a prospective member. JH feels it is inappropriate and will simply reflect against Charles Babbage, who proposed this person for membership.

Thanks JS for materials sent. Laments the decline of science in England. Believes decline has deep roots.

Explains that he does not wish to be a member of the new Board of Longitude; wishes instead to devote his energies to his research. Is leaving to travel for some months [with his bride]; cannot attend committee meetings during this period.

Is defending a change in notation for the angles of position system that JH introduced in a paper. [Postscript dated 1830-7-7 marked 'Private' and deals with business relating to the Athenaeum and a comment on Charles Babbage's book.]

Surprised at JS's response [see 1831-11-28] to his offer. Because the offer was well intentioned, repeats it and hopes that their mutual interests will lead to continued correspondence.

Commiserates with JS's problems in the construction of JS's new observatory. Seeks to smooth over a misunderstanding between them. Failing health of JH's mother.

Responds to JS's fear [see 1832-5-15] that JH has been preparing an attack on JS's double star observations by explaining in detail and providing extensive evidence that JH has no such intention.

A friend has requested JH to ask JS whether JS has a large Cauchoix objective lens that he would be willing to sell. JH has dismantled his 20-ft. telescope for voyage to Cape Town.

Assures JS that the person interested in purchasing JS's lens has worthy intentions for it, i.e., its use in a public institution. Regrets that JS distrusted JH's good intentions.

JH has seen the letter in The Times [see JS's 1838-11-12]. As JS only asked if JH's name was there, JH responds to the question of fact and does not wish further communication on the matter.
