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.

The book on the coinage of England in the 1670s is by one William Jeake. Comments on the diversity of coins available at that date and how their values changed by proclamation. Should the present coinage be decimalized he hopes the half crown will be withdrawn.
Asks for the experience of other countries in introducing decimal coinage.
Has he heard the names of the coins decided on by the Commons when the Pound is decimalized? W. R. Hamilton has informed him that he has heard from JH. Is going to the seaside tomorrow.
Thanks for AD's report on coinage [see JH's 1853-4-11], and for AD's puns.
Intends to send on Francis Baily's letters soon. Would like to see the coinage report.
Is sending the packet of Francis Baily's letters today. Sees that Thomas Wright, the Milky Way man, kept a shop in Fleet St. and was a mathematical instrument maker. Warren de La Rue has doubtless sent him his picture of Saturn.
Has found a seventeenth-century mathematical manuscript amongst Francis Baily's papers with JH's handwriting on it; can he explain the mystery? There is also a letter from P. L. M. Maupertius to James Bradley, which he proposes sending to the R.S.L.
JH's copy of Apollonius's work on conic sections was given to Francis Baily. [P. L. M. de] Maupertuis's letter to [James] Bradley is 'real prize.' Comment on AD's puns. Finds W. R. Hamilton's Quaternions 'horribly metaphysical.'
