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.
