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.
On Nov. 4 observed a red star, which does not appear in any of the recent maps or charts. Gives readings. JH may be able to throw some light on it.
Is grateful for JH's efforts in bringing his case before the government. Hopes to prove useful to the cause of science if his health permits.
Has discovered another planet {Irene]. Gives readings. Suggests source of name.
Thanks for the name [Irene]; will lose no time in making it known. Observed a faint nebulous light around the planet.
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.
Thanks for congratulations on marriage of HH's daughter. Notes HH's review of J. C. Prichard's Natural History of Man in December issue of Quarterly Review, written while on holiday in Armenia.
Marriage of HH's eldest daughter. Thanks for JH's letter of introduction to George Bishop and J. R. Hind.
Delayed answering JH's letter until HH could find details of works by 'Göttingen Professor,' but has had difficulty in locating them. Any treatise connecting epidemics with fungous origins would be of interest. Will bring distressing medical case to attention of one of HH's committees. HH's Medical Notes and Reflections, 3rd edition (1855).
Comments on JH's paper on Sensorial Vision (1858). Covered some of this ground in HH's own book, Mental Physiology (1852).
Regarding the reasons for the confusion in the nomenclature of the genus Wellingtonia and Sequoia. Comments on the aquatic Anacharis.
