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.
Writes of children's accomplishments. Discusses possible changes in nebula near Eta Argus.
Receives Mary Somerville's autobiography; explains poor health will prohibit him from detailed scrutiny of the writing.
Many thanks for the papers on the chemistry of the blast furnace. Remarks concerning this.
Comments on liquid and gaseous states of matter and on colloids; appreciates EB's kind words about JH's son Alexander.

About AD's health and the cold summer.

Thanks for answers and for notice on Apteryx [Maerurus ?], which JH remembers watching Richard Owen inspect. Interested in W. B. Carpenter's and C. W.

Encourages RP in his speculations about the nebulae and the structure of the Milky Way, which RP suggested is formed of a 'system of convolutions,' but raises objections to RP's views. Discusses idea that the Milky Way contains miniatures of itself and that beyond it may be a hierarchy of universes comparable to the Milky Way.
Discusses Olbers's Paradox, raises objections to RP's argument for the existence of dark celestial matter, and points out problems in RP's method of measuring stellar diameters.
