Asks JH to report how James South's telescope performs. There was a defect in the settings of the telescope. Hopes JH's method of eliminating chromatic aberration improves the microscope.
The Sir John Herschel Collection
The preparation of the print Calendar of the Correspondence of Sir John Herschel (Michael J. Crowe ed., David R. Dyck and James J. Kevin assoc. eds, Cambridge, England: Cambridge Univ. Press, 1998, viii + 828 pp) which was funded by the National Science Foundation, took ten years. It was accomplished by a team of seventeen professors, visiting scholars, graduate students, advanced undergraduates, and staff working at the University of Notre Dame.
The first online version of Calendar was created in 2009 by Dr Marvin Bolt and Steven Lucy, working at the Webster Institute of the Adler Planetarium, and it is that data that has now been reformatted for incorporation into Ɛpsilon.
Further information about Herschel, his correspondence, and the editorial method is available online here: http://historydb.adlerplanetarium.org/herschel/?p=intro
No texts of Herschel’s letters are currently available through Ɛpsilon.

Is engaged in preparing a new popular cyclopaedia, and would be pleased if JH would contribute an article on Light.
Sends Knowles's paper for his comments. The Board of Longitude has now been officially dissolved. Hopes the R.S.L. will not take on its work unless well paid by the government. Answers to JH's queries regarding the Nautical Almanac and other works of the Board of Longitude. Present time not good for state recognition of science.
