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.
Attached letter from Edward Sabine [see Sabine's 1847-4-7] will allow RH to communicate directly with Sabine.
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.
Skeptical over plan for galvanic illumination of wires. Has not yet seen J. B. Biot article; states he has always held Biot in high regard. Discusses naming of new planet.

Asks to be allowed to join the new Philosophical Club on a trial basis [see letter of same date to John P. Gassiot].
Asks time and place of next meeting of Philosophical Club, having received invitation lacking that information.
Comments on the paper he has sent him. Finds it difficult to give an opinion as so much verification is required.
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.
Has the papers by [Thomas] Henderson but they do not contain much information.
On a puzzling aspect of [Thomas] Henderson's papers. One column in his tables seems to have been altered in someone else's handwriting. Wants to know the origin of these corrections, and how Henderson's tables ought to be printed. Offers several options.
Believes he has worked out the German notation of star positions [see GA's 1847-2-1].
Has figured out why [Thomas] Henderson's tables [see JH's 1847-5-6] appear as they do.
Asks CB's advice on how correctly to avoid attending a Queen's ball JH has been commanded to attend.
Uses GA's comments [see GA's 1847-5-10] finally to achieve clarification of Thomas Henderson's calculations.
JH's Cape Results is ready for publication. Gratitude for support of late Hugh Percy. Regrets HP did not live to see completion of Cape Results. Trusts that AP will continue support. Asks for interview. Encloses correspondence between HP and JH to show how arrangement originated.
Further to resolving the time conflict [see GA's 1847-5-15] and sending out invitations for Visitation Day.
Sends RS his address so that RS or G. B. Airy can send proofs.
Will send measurements of the requested stars [see GA's 1847-5-15] as soon as JH can consult the appropriate papers.
Gives GA an address for the next while, and tells GA what JH has done about invitations for Visitation Day [see JH's 1847-5-19].
