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.
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.
Has visited Caroline Herschel, who is well. Discusses whether JH will make magnetic observations at the Cape of Good Hope.
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.
Does the person wishing to purchase JS's lens have a worthy objective in mind [see 1833-7-4]?
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.
Will bring a transit instrument to Slough so that JH and JS can determine its longitude. Proposes joint observations of the satellites of Saturn. Has been observing 61 Cygni.
Regrets having missed JH. Has observed the seven satellites of Saturn and the fifth star of the Trapezium. Wishes to observe some of the objects observed by Wilhelm Struve.
Has been ill. Should we publish our observations of 340 double stars or extend the number to 400?
Reports unfavorably on the telescope of A. Rogers. Information regarding Charles Babbage and his engines. Controversy concerning the Nautical Almanac.
Has examined Edward Sabine's transit measurements; finds them unproblematic.
Thanks JS for materials sent. Laments the decline of science in England. Believes decline has deep roots.
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.
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.]
