Received letter from J. H. Lefroy in Athabasca [Canada]. Extract of C. J. B. Riddell's winter magnetic operations and summer plans along Red River.
J. H. Lefroy returned from McKenzie River [Canada] having established at least 350 magnetic stations between there and Red River, 'a fine pendant for [J. C.] Ross's survey' in southern hemisphere.' If expedition continues through winter, it will provide excellent survey of North American disturbances.
Sent out copies of JH's remarks on Toronto actinometer. Expects that observations recommended by JH will be made next summer. Replacement for J. H. Kay's broken actinometer will arrive [in Tasmania] next June. Possible remedies to declination readings.
Francis Baily contracted with RT to print N. L. Lacaille's catalog of stars and J. J. L. Lalande's Histoire céleste. Account was suspended after Baily's death until B.A.A.S. meeting in York approved its continuation. Requests £300 from JH, chairman of grant committee.
Sends JH a letter from Thomas Maclear, in line with Francis Beaufort's instructions.

Having difficulty drawing the Great Nebula in Orion using both JH's and [Francesco] De Vico's observations; prints of Francis Baily are almost ready.
Does not believe that a magnetic congress held at this time would be productive or representative; a better job could be done by letter.
Expands on GA's proposed letter writing scheme in place of holding a magnetic congress [see GA's 1844-7-30].
A note accompanying a draft of the report on magnetic observations to date at British stations, and a circular to be sent out.

Describes an experiment that may explain optical 'delusion' created when stars pass behind moon. Will publish it if JH finds it worthy of publication.
Sends actinometer returns for remarks and suggestions. Mentions public dinner for scientific community.
Sends actinometric returns and drawing of comet from Hobarton Magnetic Observatory. [John] Lefroy's expedition in U.S. and Canada is going well. Received the observations from Algiers.
