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 received his book on symbolism from the publishers. Comments on some of its views. Feels he has been treated a little harshly.
Takes it that the expense of the Sinai Expedition so far carried out has been met from the funds. Sees no objections to a continuation of the expedition.
Note with return of proof of JH's biographical sketch [see WH's 1869-1-22] of William Dawes.
Comments on some incorrect attributions to JH.
Comments on the radiant heat of heavenly bodies and the motion of Sirius.
About an increase in sun spot activity.
Note to accompany the reported observations of JH's son John.
Thinks it would be best to send his son's letter to G. G. Stokes at the R.S.L. Cannot give a positive opinion on WH's plan for seeing the prominences. Finds some discrepancies in the Report of WH's paper on Sirius and the paper itself.
Suggests the planet Mercury may be a good subject for his spectroscopic experiments. Gives comments and explanations on his proposals. May like to communicate the results to the R.A.S.
Note to correct calculations in an earlier letter [see JH's 1869-9-20].
Burn his [last] letter as he made a blunder in his geometry. Cannot imagine how he made the blunder. Gives new formulae for observing Mercury.
Grieves to say that he will be unable to attend the meeting at the Royal Institution to honor Michael Faraday, as his health is so poor. Thinks Faraday was a great man in all ways.
Best wishes on Mrs. Jones's birthday.
Many thanks for Mrs. King's volume of poetry. Comments on some of the poems.
Sympathizes with Dr. C. T. Beke but regrets he is unable to contribute towards his assistance.
JH responds to UL's concern about the Isaac Newton-Blaise Pascal forgeries [see UL's 1869-10-4].
Is fully satisfied with the objections in WM's letter regarding the individual records of barometric pressure. Gives advice on how the records should be shown.
Thanks RM for his offer [see RM's 1869-1-26]; wishes astronomers would develop an accepted system of indicating the quality of observations.
Thanks CP for sending volumes of Astronomische Nachrichten. JH notes missing copies in his collection, and asks how he might best obtain these volumes.
Comments on the mathematical ratios in chords at some length, in answer to RP's 1869-11-18.
