Did not realize that JH would leave town so quickly. Cast a 10" speculum successfully after William Parsons' (3rd Earl of Rosse) plan. Is having difficulty with his grinding and polishing and would welcome JH's advice.
Sending him the elements of the new planet Astrea. Orbit is based on the Berlin observations. Differs from those given by J. F. Encke.

Has collected information about coal deposits, but GG is very troubled that the committee [coal map committee of the B.A.A.S] has not yet met and has established no procedures. Describes some of the information GG has at hand.
AS JH understands the matter [see GG's 1845-12-23], GG is the only knowledgeable member of the committee, and so it will be up to GG to present information and propose some means of moving ahead. JH makes some critical remarks about the nature of B.A.A.S. committees.
Returns to JH, and comments on, the distribution lists [for the B.A.A.S. star catalogue].
Some modifications to the telescope ordered [see JH's 1845-11-7].
