Encloses JH's letter of 11 Oct., which was not mailed to RK. Discovered traces of titanium in Astraeum. Puzzled by saline compounds that appear in JH's experiments with 'Platinoids.'
Grateful that AK withheld 'fanatical letter' addressed to Caroline Herschel. JH authorized Drummonds Bank in London to honor any check from [A. A.] Mühry up to £50 to pay for Caroline's needs. Tell Miss [Sophie] Beckedorff and Dr. Mühry to use this channel, rather than writing to JH directly.
JH's opinions regarding agreement between R.S.L. and Hudson Bay Company for survey of northern Canada. Transportation expenses should be paid by Company, officer's salary by Ordnance department, but R.S.L. may choose to bear costs in order to avoid dishonoring science. Reviews magnetic data obtained by survey.
Reports on the changes to be made to the British Museum heating system to improve heating and ventilation in the manuscripts department.
Again writes [see JH's 1847-6-9] about the heating system at the British Museum.
Agrees that H. C. Schumacher and foreign institutions should be added to list of recipients for catalogs. Please submit recommended names to B.A.A.S. Needs addresses of [W. S.] Stratford and Paramatta observatory. Complications in mailing B.A.A.S. catalog to foreign recipients.
Happy to learn that Cape equatorial [telescope] is ready. Address it to Francis Beaufort at Admiralty Office. Discusses payment. Sent [Cape Results] as GM instructed.
Is trying to establish the nature of C. I. Gerhardt's request about letters of G. W. Leibniz.
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.
Agrees to a request to forward some work to BL.
In response to a request, JH is not willing to part with any letters from his father, William, but will send one of William Herschel's notes to his sister, Caroline.
[Responding to JR's 1847-12-28], JH gives advice where to buy actinometers and what features to look for. JH cannot advise about hygrometers as these are to be used in very cold climates.
Provides details about where to buy actinometers, and what type to buy.
Tells AB about the state of education in South Africa when JH was there, comments on his part in such reforms as were made, and gives all the credit to Sir George Napier.
JH has arranged for U. J. J. Leverrier, J. C. Adams, and Wilhelm Struve to visit JH together at Collingwood. JH is writing to invite JL to join them.
Has examined southern deviation of falling bodies. His results differ greatly from WR's. Presents formula and asks WR to reconsider. Will not present these ideas to the B.A.A.S.
Has discovered a flaw in the theory of actinometer observations. Realizes that JH's actinometer observations at the Cape may be useless and that observations made at Government and East India observatories should be suspended.
Discusses use of 'force' versus use of 'power' in translating [Alexander von] Humboldt's Cosmos. Says science has outgrown 'force.' [See 1847-10-8]
States he must get to Cambridge to present his book [Cape Results] to the Queen and Prince. Seeks advice from AS on handling the matter.
Invites AS to Collingwood for Christmas. The Somervilles and the Adamses will also be present.
