Query regarding the diagrams in one of JH's articles in R.S.P.T. Has purchased one of the compound lenses on JH's recommendation, and relates some experiments with it. Would be pleased for JH to call at his house.
Is sorry he will be unable to see him. Is sending copies of their paper for distribution.
Has examined Edward Sabine's transit measurements; finds them unproblematic.
Has represented JS's interests as best JH can regarding JS's proposal. Describes himself as unskillful in such representations.
Defends Edward Sabine's transit observations, noting that JH supports them on practical rather than theoretical grounds.
Encloses paper sent by Mr. Perkins for R.S.L, and impression just received from printer.
Concludes original letter lost. Impossible to do any further work for the Encyclopaedia Metropolitana. Hopes FL will write the article.
Completing the catalogue of 2500 nebulae. Impressed with a French biography of William Herschel, although CH notes a few occasions where 'too great a stress is laid on the assistance of others.'
Their letters have missed more than once, and JH's last letter is now at the Return Office. Would like to see this letter to learn JH's views on the article on Heat. Gives own ideas how article should be written, too busy himself, so hopes JH can write it, or does he know any other person?
Apologizes for delay in writing. Describes JH's travels across Europe back to England. Is sending GP copies of JH's papers in physics, mathematics, and astronomy, especially double stars. Describes a new instrument, a floating collimator, described by Henry Kater at the R.S.L. [Rough notes for a later letter on the back of part of this one.]
Thanking him for his friendly reception when in Italy. Is sending GA journals and pamphlets likely to be of interest to him. Regarding various papers on the electrization of mercury. Please send details of Giuseppe Bianchi's barometer.
Sends JH a sketch of an experiment already made.
Is grateful for his letter and also for the brochure. Sees the folly of his own impatience. Regarding object glasses of telescopes.
Asks WS for account of the performance of his new [Josef] Fraunhofer telescope. Corroborates WS's double star motion data, except for 70 Ophiuchi, where JH and [James] South find no motion. Asks for observational targets and urges care in WS's observational technique. Mentions WS's intention to undertake celestial zone with [F. W.] Bessel. Describes [Henry] Kater's 'floating collimator.'
JF was elected associate of Astronomical Society. Will send Society's Transactions and JH's 'Absorption of Light.' W. H. F. Talbot delivered JF's 'Crown glass Prism.' JH presented J. G. Soldner's observations to Society and proposed Soldner as associate.
Presented WR's paper on a new photometer to R.S.L. Discusses how objections may be avoided. Believes [John] Leslie's photometer should be thrown aside.
Will receive 1827 Astronomical Yearbook through Mr. Hunnemann. Would be glad if he could hurry up the Parramatta Observations from K. L. C. Rümker. Various queries regarding publications.
Notes and comparisons for their recent observations of stars. Was interested in the account of Henry Kater's collimator and hopes it will be adapted for Greenwich.
Still anxious to become a fellow of the R.S.L. Thanks JH for offer. Would like to be elected before end of present session.
