Forwards list of questions from CD relating to GNS’s paper on Caldy [see 576].
No summary available.
Is grateful for the suggested emendations to his paper. Comments on the action of iodine on silver and its oxide. When can he expect publication of his paper? Has noted a peculiar property in the calorific rays when copying engravings. Encloses some Daguerreotype papers.
Is not well and is planning a holiday. Will be in the vicinity of Hawkhurst next Saturday and would like to visit JH.
G. B. Airy needs HL to send him the information used to set up colonial magnetic observatories.
Sending check and a note from the editor of the Quarterly Review.
Thanks RH for a sample of Daguerreotype paper. Comments on some aspects of the action of 'thermic' rays and 'chemical' rays in photography.
Magnetic observations have been made regularly for a year and a half at the college at Cambridge by W. C. Bond. After JH's letter another set of instruments has been obtained to make another series of observations. Money from Hugh Smithson has been loaned to Arkansas. Comments on red auroral light seen. With the more frequent steamship service now hopes for quicker communications from JH.
Is trying to reduce the ill feeling between GN and Andries Stockenström relating to the governing of the Cape colony; JH feels hampered by limited information.
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.
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.
Returns papers dealing with the treatment of Andries Stockenström by Sir George Napier.
Requests documents about the disagreement between George Napier and Andries Stockenström, which developed at the Cape. In the course of this request, JH expresses his feelings on the matter.
Reports on letter from Humphrey Lloyd and latest information from [J. C.] Ross's voyage. Has received JH's meteorological plates.
Will give Humphrey Lloyd's and his own latest magnetic data to JH for use in JH's report to the B.A.A.S. Observations continue in Milan. Year-long observations will soon be completed at Dublin Observatory. Proposes 400-page publication of simultaneous observations. Mentions Lloyd's insistence on processing incoming data himself.
Explains efforts at using a makeshift apparatus for 'fixing the spectrum.' Discusses current confusion and ultimate hope surrounding JF's meteorological recommendations. In a postscript, notes observations of meteors in Persei.
Thanks for JH's letters and the paper on photography with special reference to the effects of heat. Was present at the R.S.L. during consideration of a national observatory. Would like JH's opinion. Is working on a supplementary report on meteorology.
