Given the Treasury stance [see Richard Owen's 1858-12-18], GA sees little point in setting up one station [see JH's 1858-12-18].
Comments on JH's observing a 'falling star.'
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.
Gives formula for defining the measure of the scale of an actinometer.
About a grant to support [H. J. R.] Petersen while he carries out the reduction of terrestrial magnetic observations.
Would support the application for a grant [see JH's 1870-5-12], but would like to see some changes in the way calculations are made.
About some major variations in terrestrial magnetism readings.
Comments on GA's theory of the thermo-electric origin of terrestrial magnetism.
Has read the syllabus of GA's lectures on magnetism; it reminds JH of his attempt to solve the problem of 'Mahomet's coffin', which JH still believes would work.
About William Whewell's accident, and the ideas of E. F. W. Klinkerfüss on the behavior of light due to the motion of a star source.
About JH's visit to Carl Friedrich Gauss, and Gauss's well-devised magnetic measuring instruments.
Response to a letter from JH to G. G. Stokes [1867-5-5] seen by GA, on the problem of the effect of the telescope on illumination from a light source, especially related to a solar eclipse.
There is a need for a meeting of the Committee of Physics [R.S.L.] to discuss the current method of making temperature corrections for magnetic observations.
Detailed response to JH's 1846-10-22 about the matter of temperature corrections for magnetic observations.
Suspects that the original complainant about temperature corrections [see JH's 1846-10-22] was in fact working with a faulty magnetometer.
A committee meeting is being called [see JH's 1846-10-22].
Responds that R. A. Proctor's theory [see GA's 1870-2-5] is possible, and explains why.
Is considering a new edition of Outlines Astr.[?] and wants to provide the latest determinations of the periods of rotation of the planets.
Asks for JH's help in trying to determine the likely cost of making magnetic observations at Greenwich.
Provides information [see GA's 1840-8-13] based on equipping the Breslau Observatory; also comments on lawyers, meteor showers, and photography.
