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.
Argues against JH's position that weather forecasts cannot be made for more than 48 hours in advance.
The argument continues [see JH's 1864-1-17 & GS's 1864-1-16].

Discusses translating the Iliad. Discusses Emile Gautier's theory of the maculae, which does not seem to explain what they see.
Submits some observations concerning the experiment mentioned in JH's last letter [1864-9-25]. Discusses in detail his results of an experiment concerning the impossibility of a stable equilibrium. Decides stable equilibrium exists only in vertical position, not in horizontal. Sends another copy of his latest paper. Mentions a printing error in his memoir concerning molecular attraction.
Outlines disadvantages of establishing a gold currency in India.

Regrets 'stupidity' of Italian post office, which lost note sent to JH suggesting reprinting of passage from Treatise Astr. of 1833 on operations of sun in second edition of JT's book. Also wants to publish JT's 'extremely philosophical views' on muscle contraction.
Is not 'at liberty' to speak of experiments on change of refrangibility of 'extra-red' rays. Discusses other experiments on extra-red regions, having used various prisms but not obtaining JH's results.
JT does not have 'luxury' of using sunshine; uses electric light. Perhaps this adds to inability to obtain heat spots [see JH's 1864-11-16].
Replies to JH about the date of the transit of Mercury [see JH's 1864-1-[26]].
