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 the elements of Irene from J. F. Encke, which places the planet near Egeria. Eduard Heis has asked for JH's address as he has prepared a paper on variable stars.
Sending a table of variable stars. Appears to have seen the new planet [Psyche] on 29 Jan.
Takes the earliest opportunity of announcing the discovery of a new planet [Melpomene]. Gives readings.
Regrets the trouble JH has been caused, but it was due to the non-arrival of his letter. Cannot claim fellowship of the R.S.L. as he did not attend any of the meetings following his election. Gives a list of his planetary discoveries.
Has found another planet [Fortuna]; gives readings. Finds that the famous eclipse of Thales took place in 585 B.C., not 610 B.C., as stated by Francis Baily and Mr. Altmann.
Angelo Secchi has found the second head of Biela's comet. Gives the elements of J. R. Hind's last planet (Fortuna).
Has discovered a seventh planet [Kalliope]. Gives readings.
Has discovered an eighth planet. Gives readings. Proposes to call it Thalia.
What would JH like done with the column 'Equinoctial Time' in the Nautical Almanac?
Regrets he has been wrongly styled F.R.S. Comments on the projected Lawson Observatory at Nottingham and the high value placed on the instruments. Outlines his plan for the Equinoctial Time column in the Nautical Almanac.
Has heard from W. H. Smyth that JH is suffering from serious and protracted indisposition. Hopes he will soon be restored to health as he himself has been.
JH's copy of the Nautical Almanac for 1864 will be forwarded to the R.A.S. J. H. Mädler has solved the problem of one of William Herschel's observations.
Has been studying the star discovered by Anthelm [Voituret Anthelme] in 1670. The star he discovered in Ophiuchus has not disappeared as stated by some astronomers. Bishop is seriously ill.
Has received several letters from German astronomers on U. J. J. Leverrier's suggestions for the re-naming of the asteroids. Comments on this. Is preparing a report for the R.A.S. and would like to hear JH's views on the subject.
Is very pleased he agrees with the present system of naming the asteroids; so does G. B. Airy. George Bishop died yesterday, and the Observatory is now in the hands of Bishop's son.
Sends his calculation of the number of days from the commencement of the Julian period to 1 Jan. 1801; the result agrees with that of JH.
[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.
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.
