A note, sent with the manuscript papers of Stephen Groombridge, to JH as President of the R.A.S.
Has a problem with the explanation of interference bands produced by mica being placed between the eye and prism-produced dispersion; the explanation is Baden Powell's.
Writes to supply GA with an address for a reply to JH's 1840-5-16.
Regarding Prof. Baden Powell's paper on dark bands. Is making catalogues of the moveables of the observatory.
Considers paper by [Baden] Powell to be worthless. Sent it to JH today care of Mrs. Stewart.
Responds to JH [see JH's 1840-5-16 or later] indicating to what address GA had sent his reply [see GA's 1840-5-17].
Thanks GA for the time and trouble GA took in writing about interference bands [see GA's 1840-5-17]; JH's wife, Margaret, is making many visits to the dentist.
Concerning prism refraction.
A note agreeing with GA about prism interference [see GA's 1840-5-20].
Comments on a proposed request for a government grant to establish a magnetic and meteorological institute.
GA's correspondence with [R.S.L. president] Lord Northampton [S. J. A. Compton] will be read before Physical Committee. JH favors establishing national physical observatory and experimental institute, but wishes plan had been discussed more fully. Proposes sites, procedures, and instruments for magnetic and meteorological observations in Britain. Ideas for experimental institute.
Regarding the printing of Thomas Maclear's Survey papers. Work on magnetical and meteorological observations.
Sends JH a copy of extracts from unpublished papers on the question of standards, and asks for JH's comments on these extracts.
Copies of report are available if JH's friends on Board [of Visitors] want to see it. R.S.L. selected GA's polarity paper for Bakerian Lectures. Thanks for JH's influence.
Requests the views of JH, and all other Standards Commission members, on the various subjects before the Commission; GA will compile these and circulate them to all Commission members to expedite discussions at future meetings.
Responds to GA's circulated material for the Standards Commission; suggests time to digest the information.
Asks for JH's help in trying to determine the likely cost of making magnetic observations at Greenwich.
The Royal Observatory wants to make magnetic observations at Greenwich, and it appears will need to make some building alterations. Estimates are required immediately by the Admiralty/Treasury, and GA seeks JH's assistance.
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.
