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.

Asks AD for the return of a paper JH had sent him.
Cannot provide any specimens of photography or the spectrum good enough for an exhibition, as most have faded. A French chemist just announced as a discovery a fact long since known by JH.
Notes a small error in materials WH sent.
Suggests trustees of British Museum make an offer for Mme. Witte's lunar model. Cape Results at press. Observed double comet.
The committee dealing with applying to the government for aid should meet soon, and so JH wants some questions answered from one of the authors of Fauna Antiqua Sivalensis.
Has unsuccessfully tried to get in touch with [Hugh] Falconer and Falconer's publisher about obtaining further government aid for Falconer's research. Hopes RM, JH's fellow B.A.A.S. committee member, can help.
A collection of birthday greetings from JH, his wife, Margaret, and seven of their children, six of whom wrote their greetings in German. JH refers to Biela's Comet having thrown off a portion of itself, producing what JH calls a 'Double Comet.'

Continues JH's defense of Laplace's writings on probabilities [see JH's 1845-12-22].
A note to accompany a working out in convenient form an example of Laplace's probability ideas. [Enclosure not found.]
Reports that Biela's Comet split into two comets; JH has observed it several times. 30-40 pages of JH's Cape Results have been printed.
Does not possess enough knowledge of F. W. Bessel's writing to compose more than a brief obituary on him. Would like RS to help [A. B.] Orlebar of the Bombay Observatory by providing a corresponding observation of the occultation of alpha Virginis on 19 January.
Looks to reap fruits of observations. AQ's treatise on atmospheric waves has not arrived. R.S.L. has refused to 'receive and retain works communicated through them.'
Compliments of JH and his wife.
