Wishes to resign from the secretaryship of the Astronomical Society.
Shocked by death of [Professor E. D. Clarke], JH supports [J. S.] Henslow as candidate to succeed Clarke. Apologizes for incorrect charging of JW for Analytical Society Memoirs [see JH's 1822-2-23]. Asks JW to find out whether William Whewell will write article on physical astronomy.
Has he received the copies of the Vienna Observations? Encloses a small pamphlet of interest to mariners. What does he think of Josef Fraunhofer's micrometer for observing double stars? Is writing this letter on his birthday.
Mr. Schenck will consider favorably proposition made when JH passed through Berne, provided it is compatible with S's position and suitable for a married man.
Sends the formula for finding the maximum diameter of the planets.
Observatory plans are progressing well; GP also sends some Cambridge University news.
Would like his help on observations of double stars. Comparison of data. Gives details of stars and distances of certain planets from the earth.
Next meeting of Board of Longitude.
Regarding the method of dispatch of papers for foreign members.
Encloses JH's translation of J. J. Littrow's method of determining latitude by pole star. It already appeared in F. X. Zach's Correspondance astronomique.... Send Francis Beaufort's survey of Karamania coast.
Has had a letter from [J. C.?] Schenk of which he encloses a copy as it was possibly intended for JH. Will be pleased to hear about his expedition to Monta Rosa. Has found new method of estimating the mean temperature of the air. Was too late to see Vesuvius in eruption. Let him know if he wishes to say anything to Schenk.
Tells CB that JH has seen a calculating machine made by some 'rascally frenchman'.
Asks JH to check accuracy of Nautical Almanac entry for Jupiter's satellites III and IV on 20 Aug. 1819. Thanks for JH's note, but tell James South 'he is bound to give his reasons....'
Fears JH misunderstood TY's remark about the injustice of James South's accusation regarding Nautical Almanac. TY was not trying to provoke South's hostility. Sends 'Schumacher's No. 10' for JH's perusal.
Discusses JS's efforts to reform the Nautical Almanac, including JS's Practical Observations on the Nautical Almanac. States that in this 'awful crisis' JS has no hostile feelings toward its superintendent, Thomas Young.

P. L. Guinand has informed the Astronomical Society that he can make flint glass free from the usual imperfections. Would like any information from JN. One of his papers has been named as likely to receive a prize. Hears that an arithmetical machine has recently been demonstrated before the Institute. Have any details been made public?
