His recent tours in Italy and Germany, and the people he met.
Is glad to hear of his speedy return. Regarding JH's instruments and their passage through the customs. Is writing a book on Assurance Companies.
Regarding the change of ownership and policy of the Edinburgh Philosophical Journal. Would like a paper from him for the first number. Marked 'Private.'
Praises old Edinburgh Philosophical Journal. Promises to send DB some materials for publication.
Has just received his letter and Struve's observations. Comments on these and those of F. W. Bessel.
Mislaid the copy of one of JB's mss. and would be grateful if he knows of its whereabouts. In the course of his travels in Europe he has seen some astronomical instruments, which will in time surpass any British made ones and especially those of G. B. Amici and Josef Fraunhofer.
Has only fragments of the paper for which JH inquires; original was left for W. H. Wollaston to amend. Thanks for congratulations on the award of the Copley Medal. Was interested to hear about the new German astronomical instruments.
Sends GA information about indices of refraction in different glasses and in different parts of the spectrum; also recommends the writings of Josef Fraunhofer.
Is sending a letter from Dr. John Brinkley, and the corrected elements of the comet.
Regarding the magnetic polarity of the earth.
Sends pamphlet on observations they made together on Mount Cuccio. Regarding the coefficient of expansion of the atmosphere. Will repeat his observations in the coming winter. Present the other copy to the Astronomical Society.
Would be pleased if JH would obtain some flint-glass for him when he goes to Munich.
Packets will be sent Saturday by Smith, Elder & Co., so that the one for [Caroline] Herschel will not be late for Mr. Köhler.
Requests answer to JP's earlier letter. Observations of photospheres around planets and satellites.
Observations of Venus by William Herschel and JH. Only J. H. Schröter claims to have seen 'deep marginal indentations' that JP claims.
Has received JH's note, and JF will visit JH next Wednesday, accompanied by D. F. J. Arago and [C. L.] Mathieu.
Please recommend London instrument makers to supply new Edinburgh observatory. Josef Fraunhofer was asked to make only lens for transit instrument, but wants to make entire instrument. [JH annotation: Recommended Fraunhofer for entire transit instrument and Robert Molyneux for clock.]
Repeat computation for Jupiter's satellite IV [see TY's 1824-4]. Explains W. H. Wollaston's 'blue bow.' See figure 422 of TY's [Lectures on Natural Philosophy].
As R.S.L. vice president, JH should reconsider his report favoring Eilhard Mitscherlich over W. H. Wollaston. This may be last opportunity to pay Wollaston a 'just compliment.' Agrees with JH that much in R.S.L. 'nicknamed science [is] sleight of hand,' and that 'great injustice is done to men of science.' But TY expects a short life and tries not to be concerned about approval of others.
TY would rather have JH's labor made useful another year. W. H. Wollaston does not want [Royal] medal, but medal wants Wollaston. One council member felt that TY's remarks offended JH. Assures JH it was not intended.
