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.

Would like to visit the Mint with his family.
Demand for silver coins by Commissariat department [in Malta] must wait until Mint has met demand by Bank [of England]. Address all official letters to C. E. Trevelyan, even if responding to letters signed by GA.
[Marked 'Private.'] Governor of Bank [of England] is in 'great fuss' about not receiving silver coins. What is Mint doing? Suspects some 'nonsense' behind this urgent demand for silver. In C. E. Trevelyan's absence, GA will not act precipitously.
[Marked 'Private.'] Ordered Commissariat officer in Malta to send home £51,000 of silver coin for use by Mint in meeting demand of Bank [of England] for coins to export. Wishes government would take steps to reduce export of silver. Concern over public reaction to reducing silver content of coins.
Considers Thomson Hankey's note ridiculous; pressure by Bank of England for more silver coinage is unnecessary. Reassignment of Mint residences to Mint officers. Discourages plan to extend piece work wages to include Mint officers.
Procedures for evaluating refinery leased to Anthony de Rothschild. Problem of accurately weighing small coins. Size of permanent staff in Mint office should be determined by ordinary work, not by times of pressure. Consider borrowing temporary clerks from other government offices. Returns draft of JH's letter to Rothschild.
Wages for a weighing room assistant. There is no extra copy of Coinage Act. Believes Treasury would approve of bonus for delivery of more silver or gold than planned.
Recalls meeting JH in 1840, introduced by R. C. Stewart of Bombay. Saw JH's letter on artificial production of ice in Year-Book of Facts for 1851 (p. 157). Describes WM's unsuccessful experiments with commercial powders in tropical climate. Asks for information about portable air compressors. Local surgeon, Dr. Porteus, whom JH met at Cape of Good Hope, asks to be remembered to JH's family.
Offers some explanations for the reports in the papers [see JH's 1852-9-6] of seeing strange objects in the heavens; GA calls it 'hemiplegia.'
Sends parallax measurements for Alpha Centauri.
William Mann goes to England to receive transit circle. TM describes plans for the instrument.
