Seems clear that JH's 'falling star' [see JH's 1845-4-29] was the same one reported by a correspondent of GA's as having been seen in Nottingham; in a postscript JH is not so sure.
Comments on the various responses to the circulated questions about magnetic observations [see JH's 1844-12-5].
Describes testing William Simms's object glass and then gives details of the equatorial mounting GA used; offers to send carpenter to JH to construct mounting so JH can test object glass [diagram].
Is anxious to know whether JH has used William Simms's object glass, and seeks JH's opinion.
Provides JH with the latest Royal Observatory values for Gamma Virginis [see JH's 1845-9-30], and advises JH to change his method of measuring double stars.
Still trying to solve the problem of jogging Robert Peel's memory [see JH's 1845-10-8].
Thanks JH for his report on William Simms's object glass trials [see GA's 1845-9-29], together with some other astronomical matters, including reference to a letter from F. W. Bessel.
A note to accompany the return of a letter to JH.
Has received a satisfactory response from the Admiralty [see JH's 1845-9-30].
Asks JH to write to George Merz for an object glass for a telescope for the Cape Observatory.
Is writing about further arrangements about the telescope to go to the Cape Observatory; JH is negotiating with George Merz for it [see GA's 1845-10-28].
Has requested Admiralty funding for the proposed telescope [see GA's 1845-11-2]; GA does not like the mounting the telescope is to be given; has gathered, from Otto Struve, that it does not work well at Pulkowa Observatory.
Is returning JH's report on William Simms's object glass [see GA's 1845-10-14]; GA reiterates Otto Struve's statement about the mounting at Pulkowa Observatory [see GA's 1845-12-1].
The Admiralty has approved the purchase of the telescope for the Cape Observatory [see GA's 1845-12-1].
A note of instructions about paying for the Cape telescope [see GA's 1845-12-20].
Seeks GA's assistance in solving a puzzle in the mathematics of rotating bodies.
Provides the best values available for dispersion and separation, which will allow GA to calculate what he needs [see GA's 1845-4-4].
Is skeptical of the American observations [see GA's 1845-12-8], and reports other observations communicated to JH.
Asks for new observational data on Gamma Virginis [see JH's 1843-7-18].
Believes GA's measurements [see GA's 1845-10-1] seriously in error, and strenuously defends JH's method.
