Agrees to contribute to W. S. Stratford memorial presentation. Agrees with JH that Jupiter satellite observation was an optical illusion; sends sketches of more Jupiter observations. Sends data obtained with new instruments.
Microscopes installed successfully. Describes observation of second satellite of Jupiter transiting the disk of the planet and how it seemed to linger at the planet's edge.
Hopes to meet with Charles Babbage in Vienna. Inquires if JH received a set of books from University of Padua for the Astronomical Society. Praises JH's double star work; uses it for own observations.
Giving news of the intentions of her son (Charles Babbage) and his experiences on his travels.
Further regarding Richard Taylor the printer. Reports on observations of Mars by William Pearson. JH's new micrometer is aiding his observations of double stars.
Regarding the printing for the Astronomical Society. Errors in FB's astronomical tables.
Thanks for the two communications. J. F. Encke's work on the Ephemeris. Francis Beaufort's remarks concerning Richard Taylor the printer. Hoping for fine weather for observations.
Regarding Richard Taylor the printer and the printing of the papers of the R.A.S.
Mr. Knowles has left college and taken the plates of quartz that illustrated the experiment so well. Sends further explanations of the experiment he previously mentioned to JH.
Encloses letter from Edward Ryan. NW departed Bengal on 10 Mar. and brought home [8,000+ plant specimens] for H.E.I.C.
Discusses atmospheric refraction, Francis Bacon's distinction between argument and testimony, and the manner in which the Board of Longitude was dissolved.
[Richard] Taylor is very anxious that the Astronomical Society reconsider its decision to discontinue his services as printer of the Society's publications. Suggests presentation of a gift to William Stratford for his services as secretary of the Astronomical Society.
Has found some errors in the sheets of computations HK sent. Lists these. Comments on astronomical work of [William] Richardson and on the reading of 'The repeal of the Longitude Acts Bill.'
Has given away all his drawings; all he has left is a small oil-color of Christiana. Comments on the scenery of Norway. Hopes the paintings will stimulate interest in a country of which he is very fond.
Hears that the Board of Longitude is to be dissolved; it will therefore be necessary to seek a new source of income for the continuance of the Optical Glass experiments. Will be guided by MF's wish whether to continue the experiments. Charles Anderson has showed him curious experiments with the fusion of Fluor with clay.
The furnace is breaking away at the top, and he encloses Joshua Ramsay's estimate for its repair. Thinks the present a suitable time for the repairs. Would JH speak to the Council?
Understands the Board of Longitude has been dissolved. Wonders what the position now is regarding the Optical Glass Committee. Outlines his own views and would welcome DG's instructions.
Has just returned from an exhausting meeting. Has no doubt funds will still be available for the Optical Glass experiments. Has written to Michael Faraday.
Has had a note from J. W. Croker stating his willingness to help. Would like a sketch and details from Michael Faraday of the experiments now going on.
