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.
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.
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.
Provides information [see GA's 1840-8-13] based on equipping the Breslau Observatory; also comments on lawyers, meteor showers, and photography.
Has passed on GA's note to Edward Sabine; cannot write more because his hand shakes too much, having just made a snow-man for the children.
Sends a letter from Humphrey Lloyd for GA's comments.
Thanks GA for his comments [see GA's 1842-1-18]; hopes that GA would be willing to have such statements, and other similar statements, made public.
Asks GA's opinion as to whether Ordinance observatories should make their magnetic observations on a 3-minute or 5-minute system.
Is organizing a committee to revise the instructions for observers at magnetic observatories; GA is on it.
Suggests to GA that his observations [see GA's 1847-11-1] might rather support than destroy the theory of the thermo-electric origin of terrestrial magnetism.
Passes along a report that someone took a 4-foot telescope to the top of Snowdon [mountain], from where he could see the eight satellites of Saturn and the rings of Neptune.
Expresses unease about P. S. Laplace's formulation of the barometric determination of height; in a postscript comments that Michael Faraday's lecture on conservation of force is a 'strange production.'
Has received GA's paper on spectral lines and is amazed that it is possible to see a spectrum in the light from faint nebulae.
About observing a grain-shaped spot on the sun; greetings to Friedrich Winnecke.
Sends GA [see GA's 1863-11-21] JH's copy of the Melbourne telescope correspondence and reports; needs information from GA and Edwin Dunkin about the sun's motion, although JH questions some of Dunkin's work.
Thanks GA for the papers sent; asks GA to review enclosed note on solar motion [see JH's 1863-11-22].
Has received the papers [see GA's 1851-10-7]; Sydney University seeks assistance in finding professors. What should the response be?
An invitation sent out by JH to invite all search committee members [Sydney Trust] to JH's house [see GA's 1851-10-16].
Note with copies of an advertising circular about the Sydney University professorships [see JH's 1851-10-16].
