Admiralty has approved equatorial telescope for Cape of Good Hope Observatory. Advise JH to order it from Munich.
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.
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].
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.
Thanks JH for his help [see JH's 1840-8-14], and tells JH about a visit to Greenwich by Charles Wheatstone.
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.
Provides extensive comments, about GA's magnetic instruments and observations, in reply to Humphrey Lloyd's letter [see JH's 1842-1-17].
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.
