Arranging a visit for GA to Collingwood.
Final arrangements for GA's visit to JH [see GA's 1842-3-15].
Does not feel qualified to judge the merits of the various makes of telescopes. Suggests that the Astronomer Royal may be able to help or one of the other observatories.
Thanks AD for the corrections to JH's writing on astronomy; congratulates AD on his book on differential calculus.
Received prospectus of Kew observatory. Its objectives seem incompatible. It appears better suited as experimental institution. Refer Francis Beaufort to JH's 11 Oct. 1835 letter to Beaufort defining physical observatories.
[JH's outline of letter] Compares Wilmot's actinometer observations with JH's. Acknowledges receipt of St. Helena specimens.
As many Russian observatories are now involved in magnetic observations, JH thinks the British observations should continue [see GA's 1842-1-22].
Grateful for being made Knight Commander of the Illustrious Order of Dannebrog, but British rules forbid JH accepting foreign title.
Received WB's atmospheric curves yesterday, but too late to report them [at 1842 B.A.A.S. meeting]. Final report will be presented at next [1843] meeting.
Reviews WB's assistance in JH's meteorological investigations as testimonial on behalf of WB's application for position of curator at Kew Observatory.
Must complete graphs of barometer curves before B.A.A.S. meeting. Did JH mistakenly include 1837 Bogota Almanac in barometer observations?
Sends two dozen more papers on barometer graphs. Must have all papers on subject by January. Pleased with WB's lunar observations.
Offers to meet FB at Manchester B.A.A.S. meeting and to bring FB to Collingwood for a quiet visit.
Detailed arrangements for FB's visit [see JH's 1842-6].
Comments on expected honor from Prussian government and on British rules against officially accepting it.
Informs FB on how to visit Woolwich Arsenal and Dock Yard.
Would be pleased to be visited by C to discuss the application regarding glass [lenses] of various algebraic formulae devised by JH. Will also show C some of JH's recent work in photography.
Appreciates receiving the curious fossil, even though JH knows little of such matters.
Responds to RM's request for an analysis of the cause of the difference in climate between Orenburg and Catherineburg in Russia. Agrees that Geological Society can print JH's Alpine memoir.
