Recommends Robert Hunt to fill the professorship at King's College, left vacant by the death of John F. Daniell.
The continuation of magnetic and meteorological observatories is under question, and CW's instrument for observing atmospheric electricity should be part of the discussion.
Makes some amendments in JH's request for information [see JH's 1845-4-6].
Asks for CW's contribution to the Admiralty's scientific manual.
Strongly supports W. E. Weber as the best candidate for the receipt of the Rumford Medal [see CW's 1849-11-10].
Invites CW to come out to Collingwood next week when some other friends are coming, too.
Is pleased CW is coming [see JH's 1849-6-29]; JH asks CW to bring some of his apparatus to do polarized light experiments.
Too ill to attend a demonstration by CW of one of CW's instruments [?].
Agrees to meet JH and Edward Sabine on Saturday. Kew Observatory was given to R.S.L., but R.S.L. has not yet taken possession of it. [JH annotation: election of General Morrison to R.S.L.]
Postpones visit of Lady [Margaret] Herschel to CW. Wishes to take CW's Symphonion to Slough. Has made favorable mention of CW's tuning fork experiments in paper on absorption [JH's 'On the Absorption of Light by Coloured Media...'].
Discusses when and how often R.S.L. committees, particularly the physical committee, should meet.
Appreciates JH's interest in and encouragement of CW's experiments. Describes new experiments to elucidate theory of undulatory motion of sound and light. Invented 'kaleidophone' to display paths of vibrating rods. Hopes JH can confirm these results.
Invites CW to Slough to demonstrate CW's 'elegant experiments on light & sound.' Will need time to get JH's electric machine in order. Asks for copy of CW's paper on Jew's harp.
Accepts JH's invitation to demonstrate [on 28 Aug.] CW's portable optical and acoustical experiments and the 'whirling machine.' Asks JH to supply 'an electrical machine and a good sized jar.' Encloses copy of CW's paper on Jew's harp. Will bring another paper and new 'Symphonion' for Mary Herschel.
Returns Mary Herschel's repaired concertina. Sends CW's recent paper on velocity of electricity [R.S.P.T. 124 (1834)]. Electrical experiments CW is planning. Appointed professor of experimental philosophy at King's College.
Invites JH to Kew Green to see Francis Bauer's plates etched by J. N. Niepce's photographic process. Perhaps L. J. M. Daguerre assumes more credit than is due. Heard Niepce visited London in 1826, but his paper was rejected by R.S.L. at W. H. Wollaston's urging.
Encloses B.A.A.S. statement of objectives for Richmond Observatory, for which B.A.A.S. Council asks JH to organize goals and support annual subsidy.
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.
Agrees that vacancy in chemistry professorship left by J. F. Daniell's death at King's College should be filled by Robert Hunt, but W. A. Miller appears likely to get job.
Gives JH directions to Kew Observatory.
