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.
Asks JH's opinion about GA's plan not to print a separate volume of magnetic and meteorological observations for 1848.
Will reconsider the proposal about printing observations [see JH's 1849-3-29], and get back to JH.
Is passing on a request for a copy of JH's Cape Results from C. L. Littrow of Vienna.
Has little advice to offer JH about time calculation [see JH's 1849-3-29], except for fairly standard reminders.
Glad to hear that Margaret Louisa [JH's daughter] is coming to visit GA's family; could JH send along the key to the R.A.S. strong box?
A note about forwarding papers related to the double star question [see JH's 1849-4-9].
Some responses to the question of copyright and of revision of articles prepared for the Encyclopaedia Metropolitana.
A note of thanks for a copy of JH's Outlines Astr.
Regarding the 'chilled' casting of a telescope.
Returning papers of Yvon Villarceau and an abstract of them, together with comments on them.
Informing JH that they have been appointed members of a committee for proving a three foot reflector for the Cape Town Observatory.
Responds to a JH question about the accuracy of the calculations for the figure of the earth in GA's article in the Encyclopaedia Metropolitana.
Is William Dawes equatorial telescope available for purchase?
Tells GA about the internal counterpoise system in use in some German telescope mountings, and includes a diagram; JH knows nothing about chilling speculum metal [see GA's 1849-3-7].
Some concerns about GA's intent of attaching magnetic and meteorological observations to the R.A.S.'s Astronomical Observations [see GA's 1849-3-28].
Has heard nothing beyond what GA has said [see GA's 1849-9-25], but agrees with GA's assessment of the situation.
A number of copies of the Cape Results were sent out, including one to Charles Ludwig Littrow [see GA's 1849-6-22]; JH will now try to trace the books whereabouts.
Asks GA if he knows of any rules or pitfalls in calculating time from earlier times [even B.C.] to the present.
Responds to GA's 1849-4-4, and sends the key.
Is making a case for JH's priority claims with regard to the means of determining double star orbits, in conflict with Yvon Villarceau.
