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.
Has now heard that the explosion at Dover is to take place on Thursday. Hopes to see JH there. If not, will call on him at Hawkhurst.
Has ventured on the risks of an election to the R.S.L. and would like JH's support and influence with those on the Council. Was prevented from visiting Dover. Sails for Canada on 4 Mar.
Should JH be attending the B.A.A.S. meeting at Cork, hopes he will visit WP and spend a few days with him. Gives news of the progress of his great telescope.
Comments on the value of meteorological observations that TP proposes to undertake.
Is inquiring, on behalf of the Admiralty, about ordering an equatorially mounted achromatic telescope for the Royal Observatory at the Cape of Good Hope.
Approves GD's modification of driving wheel [for JH's actinoscope]. But GD's cost estimate exceeds total R.S.L. grant of £100. JH cannot approve more than £70; must have funds left for optics and clockwork mechanism.
[Writing in response to Archbishop [of Canterbury, William Howley]], accepts the honor of being named a Trustee of the British Museum with much gratitude.
Peter Stewart informed JH of EM's offer to assist JH's son William in obtaining writership appointment in India. JH and wife are deeply grateful. JH's desires for William's future.

Talks about British Museum business, including the purchase of fossils and the hiring of George R. Waterhouse.
[Writing to the Archbishop [of Canterbury, William Howley]], recommends George R. Waterhouse as a candidate for employment at the British Museum.
Expresses GW's concern if the British Museum were to require him to pledge to do no remunerative work outside what they would pay GW to do. GW, however, is prepared to make that pledge, if necessary.
Construction of JH's new instrument for photographing spectral lines is still incomplete, and A. E. Becquerel has already announced discovery. JH will return £100 granted to JH by R.S.L.
Encloses bill, which JH signed, received from J. C. Stewart. JH and family visited Dover with G. B. Airy's family, where JH witnessed noiseless explosion of 18,000 pounds of powder distributed over 18 acres.
Sorry to have caused trouble. Please send JH's 'description and sketches' to Peter Stewart at 65 Cornhill.

JH's account of a comet reminds WT of a strange sighting many years ago. Comments further on improvements in photography, both those made and those needed.
