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].

Informs JH that GA has stated that he will no longer work with James South on the Board of Visitors of the Royal Observatory; wants JH to be prepared for possible trouble.

Essentially agrees with JH's plan for distribution of the star catalogues [see JH's 1846-11-18].

A notice of meeting of the Standards Commission.

Offers his suggestions for any trimming of the catalogue distribution list that may be necessary [see JH's 1847-11-17].

Responds to some of JH's concerns [see JH's 1847-12-30] about changes in instrumentation at the Royal Observatory.

A note accompanying a printed circular about the proposed changes in instrumentation at the Royal Observatory. [Encloses GA's circular to Board of Visitors.]

Proposes changes in the buildings at the Royal Observatory to accommodate the shifting of one of the telescopes [see GA's 1848-1-6].

Responds to a number of JH's concerns about buildings, instruments and printing at the Royal Observatory [see JH's 1848-1-22 & 1847-12-30].

Wants a meeting of the Board of Visitors to determine the extent of time to be given to magnetic and meteorological observations at the Royal Observatory.
