Received JH's letter [29 Apr. 1821] with 'Memoirs of Astronomical Society' and observations of recent solar eclipse. Has not published eclipse calculations. Convinced that moon's diameter is accurately determined. Latitudes, longitudes for sites in Finland. 1820-22 observations from Ã…bo. Design of new Ã…bo observatory. New instruments from Munich.
Board of Longitude reluctant to pay for new building at James South's unless South and JH agree to place their observations at Board's disposal.
Next meeting of Board of Longitude.
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.
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....'
Has no errands for JH in Holland or Flanders. Asks for details on JH's and Charles Babbage's method of determining heights by barometrical observations. Hopes to use this to confirm TY's method by 'my formula deduced from refraction.'
Thanks JH for the letter informing FZ of his nomination to the Astronomical Society. Describes how JH can send packages to Geneva via the British Consul.
EW and daughter look forward to visiting Slough on Monday with Mr. Beckwith.
Please forward enclosed papers.
Begs JH to leave work and relax with RJ and William Whewell at RJ's house.
Gives directions for some time measurements involving rockets JS was planning in conjunction with JH. Mentions various double stars.
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.
Regrets having missed JH. Has observed the seven satellites of Saturn and the fifth star of the Trapezium. Wishes to observe some of the objects observed by Wilhelm Struve.
Urges JH to come to Brighton and then to return with him to Cambridge; stresses that both he and Richard Jones are anxious to talk with JH.
Discusses regions of the Alps and sends sketch of Monte Rosa. Informs JH of a brilliant student, G. B. Airy, who is constructing a calculating machine. Condolences on the death of William Herschel.
Encloses list of books on Ireland as requested. Her brother is in London. Hopes that JH will visit them should he come to Ireland.
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.
Would like very much to see JH as soon as possible. Has an instrument of [J. C.?] Schenk to show him. There is one on the way to him now from Paris.
Cannot leave the instrument with Edward Troughton later than Saturday. Perhaps Troughton had better leave the instrument in the box until GE calls.
