Apologizes for having been too busy to sit for a portrait as proposed, thanks HO for his poems, and describes JH's current experiments related to photography.
Received Hobhouse's letter of 27 May with reply from H.E.I.C. board of directors regarding establishment of magnetic observatories in India. D. F. J. Arago recommends additional station on Socotra Island [in Gulf of Aden].
Describes three-year magnetic survey proposed by R.S.L. Asks H.E.I.C. court of directors to provide support for three observing stations: at Madras, at Bombay, and in Himalayas. Humphrey Lloyd will supervise training of observers.
Grieved that J. C. Stewart desires schoolmaster position at Cape of Good Hope. Attests to Stewart's many business talents, and asks HP to find 'more prominent station' for Stewart.
[Extract] Suggests change in proposed distribution [of Cape Results]. Richard Sheepshanks offered to subsidize portrait of JH, to be distributed with complimentary copies [of Cape Results].
Just received RP's Dec. 1837 observations, forwarded from Cape of Good Hope. JH is now president of R.S.L. joint committee of Physics and Meteorology. Meteor shower of 10 Aug. 1839. Describes global magnetic survey conducted on Göttingen Mean Time. Hopes U.S. will join survey. [Enclosure: Printed notice of global magnetic survey, listing participating governments, purposes, and instruments.]
Willing to write to [secretary of state for War and the Colonies, Charles Grant] Lord Glenelg on behalf of JS's application. JH searching for new residence.
Sends letter of recommendation for JS and returns draft of JS's letter to [Charles Grant] Lord Glenelg, with recommended changes. Promise from Glenelg's father to JS's father [A. Stewart] is grounds for JS's application.
[Richard] Jones's view is correct. Will wait to hear what Mr. [Meade?] has to say, before JH writes to Mr. Hodges.
Birth of [Maria Sophia Herschel]. Awaiting JS's news about Bombay. John [Stewart] and Matilda [Grahame] sailed for France yesterday.
Sent WT's specimens to J. B. Biot and F. J. D. Arago in Paris. Developed paper sensitive to heat rays of sun 'beyond the spectrum.' Diagram of three spectra: 'luminous, chemical, and thermic.'
Commends JW's application for Savilian professor of astronomy at Oxford [see JW's 1839-3-22]. But it is improper for JH to propose JW unless asked to do so by R.A.S. council.
Considerable comment on procedure for submitting paper to R.S.L. Urges WT to mention JH's method of washing with hyposulfite. Comments on some photographic experiments of WT.
Submits payment to J. D. Roberton for 'Association' bills. Glad that ES approves of JH's draft article on terrestrial magnetism for Quarterly Review. Fears R.S.L. was premature in proposing experimental institutions; public was not prepared for such large expenditures for science. Prefers ES's suggestion of temporary magnetical and meteorological observatory. Strong disagreement from [C. J.] Riddell in America.
Departure of J. C. Ross for Antarctic expedition is approaching. Hopes that Admiralty will soon authorize R.S.L. to assist Ross in preparing instruments and coordinating global observations.
Will send two photometers and three-year supply of paper to [?]. One goes to J. C. Ross and one to F. Eardley Wilmot at Cape of Good Hope. Instructions for using photometers. Hopes [?] Robinson forwarded actinometers to Woolwich as JH directed. These should be checked at St. Helena. Instruction for using actinometers. Sent report to Humphrey Lloyd at B.A.A.S. Returns [?]'s Daguerre newspaper containing 'impudent notice about M. Pambour and his great Wheels.'
Accepts invitation to party next Tuesday. Regrets not visiting more often at Cavendish Square or Hampstead. JH's wife and 'little one' are well.
[Two copies of] Printed letter from R.S.L. announcing proposed system for global magnetic observations. [One copy edited by JH for submission to "Your Highness" with] Request for assistance in adding magnetical observatory to John Caldecott's astronomical observatory in Travancore [India].
Report to B.A.A.S. on progress and expenses in reduction of stars in N. L. Lacaille's Coelum australe stelliferum.
Let India Board move at its own pace, and do not call on Lord Northampton. JH will write privately to 'Major J.' to suggest proper training for appointed observers.
