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.

[James?] Ferguson wants Titania changed to Echo, which he has now inserted in the forthcoming Nautical Almanac. H. M. S. Goldschmidt has recovered Pseudo-Daphne. U. J. J. Leverrier does not wish to name No. 59.
Will incorporate his suggestion respecting the introduction of the current Julian date in the Nautical Almanac. The name 'Baucis' has been proposed for No. 59. Has sent U. J. J. Leverrier his own views on nomenclature. Bishop's Observatory may be moved to Twickenham.
Will send the Nautical Almanac to Smith, Elder and Co. Is pleased they agree on the naming of the asteroids. Gives readings for the approaching transit of Mercury.
About the naming of asteroids.
Has received a letter from U. J. J. Leverrier requesting a name for No. 59; sees difficulties; so would JH suggest a name. Has sent the Nautical Almanac supplement and a memoir by Yvon Villarceau to Smith, Elder and Co.
Suggests the name 'Clio' for asteroid No. 59. Gives a list of proposed names for asteroids.
Is grateful for the ample list of suggested names for asteroids that JH has sent. Outlines the difficulties over the name 'Clio'. Would prefer 'Olympia.'. Believes 'Pseudo-Daphna' will be called 'Galatea'.
Regarding the apparent disappearance of a nebula. Comments on this.
Cannot see how there can be two opinions regarding JH's catalogue of nebulae. Suitable work for the R.A.S. to publish. Further regarding the lost nebula in Taurus.
Has been considering how to incorporate JH's suggestions regarding the insertion of the Julian dates in the Nautical Almanac. Would like his views. Quotes extracts from a letter of U. J. J. Leverrier.
Encloses slips to show how he has incorporated the Julian dates. Agrees with the American lunar tables. The nebula in Taurus is invisible to William Lassell.
Was interested to receive the information regarding another missing nebula; would like to mention it at the R.A.S. The late George Bishop's observatory is now being rebuilt at Twickenham. Will return N. R. Pogson's table of Julian dates tomorrow. Has adopted the first of JH's suggestions.
Returns N. R. Pogson's tables. Has received a communication from [W.?] Lummis concerning a dark spot on the sun's disc. Has been unable to make any calculations yet.
Would like JH to add his signature to Hind's certificate for the R.S.L., and then forward it to G. B. Airy.
Explaining the discrepancy in the Nautical Almanac; will endeavor to make a clearer explanation in the next edition. Returns JH's son's memorandum.
Sees that JH mentions 'the longitude of perihelion on the ecliptic' as one of the elements he would like to have in the case of the small planets. Would like his advice.
Comments on JH's advice regarding the 'longitude of perihelion in the ecliptic.'
Explaining some of the signs in the enclosed table. Has sent the Nautical Almanac for 1867.
Sending the revision of the first half sheet for the 1867 supplement containing the latest elements of the small planets.
