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.

Notes that actinometer observations prove faulty due to problem with instruments. Asks that WS notify Indian observatories to join others in terminating such observations until JH finds method of getting around problem.
Approves naming the new planet Neptune and continued designation of JH's father's planet as Uranus. Suggests reasons and alternatives.
Speculates on name for JR's 'hot and cold basins' and on causes of equatorial heat and polar cold.
Believes he has worked out the German notation of star positions [see GA's 1847-2-1].
Asks to be allowed to join the new Philosophical Club on a trial basis [see letter of same date to John P. Gassiot].
Uses GA's comments [see GA's 1847-5-10] finally to achieve clarification of Thomas Henderson's calculations.
Thanks WH for 'plan' of [asteroid] Iris. Family is happy to have WH's son (JH's son William's friend) with them for holidays. Recounts their playful and adventurous activities.
On WH's 'Hodograph' and theorems of parabolic motion and the relation between velocities, initial velocities, and time. Praises WH's son. Cape Results nearly finished. Revising book on astronomy. Plans to 'attack' quaternions. Mentions parabolic functions and Benjamin Peirce's claim that the discovery of Neptune was accidental.
Has dealt with the problem of thanking H. C. Schumacher [see GA's 1847-10-6].
Is still working on the distribution list for star catalogues [see GA's 1846-11-19].
Advice as to best way to present JL's method of calculating the orbits of comets to R.A.S. If JL desires R.A.S. to undertake calculations, might be some difficulty.
Asks time and place of next meeting of Philosophical Club, having received invitation lacking that information.
Reports on and recommends for publication experiments in paper [see RSPT, 137 (1847), 253-] by [A. F. J.] Claudet on effect of solar radiation on silver plate's mercury deposit, but questions conclusion about triplicity of photographic action.
The books are on their way [see GA's 1847-3-30].
Seeks London bookselling agent through whom to direct copies of JH's Cape Results for Dublin scientific groups. Discusses pretty names for new planets. Thanks for WH's memoir on quaternions.
Will be happy to supply a copy of the Cape Results [see GA's 1847-9-27]; the next asteroid should be called Flora, to provide 'young goddesses for Mars and Jupiter to admire.'
Encloses post office order; not knowing WG's 'Christian' name; hopes that WG can sign 'William.' Apologizes for being unable to attend 'the Dinners.'
Believes all actinometric measurements made are useless because they did not take into account the rate of expansion of the liquid, which is not constant.
Asks whether JL wishes to present method [see JH's 1847-12-4] at next R.A.S. meeting.
