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.
Looks forward to the new edition of JH's Treatise Astr. Comments on the atmosphere and gases on the surface of the moon. What does JH think of these comments?
Invites CW to come out to Collingwood next week when some other friends are coming, too.
Is pleased CW is coming [see JH's 1849-6-29]; JH asks CW to bring some of his apparatus to do polarized light experiments.
Regarding the work of Yvon Villarceau on double stars. Would like a reference from Sir William Herschel's paper.
Has just been able to consult Sir William Herschel's papers. Regarding Yvon Villarceau's method of measuring the orbits. May be like his own, which he briefly outlines.
Would like to ask a few more questions regarding JH's method outlined in his last letter. Can UL submit it to the Institute?
Found his letter on return from London. Would be pleased for UL to submit part of his letter of 19 Mar. to the Institute. Further comments on part of this letter.
Read part of JH's letter to the Institute and Yvon Villarceau also presented his own method. Will see the letter printed in the Comptes rendus.
Encloses some sketches to show some remarkable changes in solar spots. Would he place the observations before the R.A.S. when finished with them.
Has just received JH's letter giving details of an interesting auroral phenomenon. Has been experimenting with wire insulates. Henry Lawson has observed streams of red light resembling aurora.
Has just published a small work to remove popular superstitions. Presents a copy to JH as a mark of respect.
Sending printed notice appealing for funds to establish a Midland Observatory. Would like a word of encouragement from JH.
Giving his views on the desirability of establishing a Midland Observatory.
Thanks for his letter regarding the proposed observatory. Points out some provisions he intends making for the observatory. Encloses extracts from letters favoring the scheme.
JH is now very supportive of EL's intention of establishing a Midland Observatory following EL's 1849-11-12.
Even though he was Vice-Chancellor [of London University], he had no opportunity of becoming acquainted with the internal regulations of the colleges connected with the University. Regarding the education of young children. Sends some music for Lady Herschel. Would like them to pay him a visit.
Was not at home when JH's letter arrived. Appointment of John [JH's son] is to all intents JH's own, and Leslie Melville will sanction any appropriation JH may desire. Thinks that JH and his wife should consider the situation before embarking further.
Has seen Leslie Melville who can be relied on to give John [JH's son] the Addiscombe appointment.
Has judged wisely for Willie [JH's son] in the present uncertain state of his health. Theodore Hope has just returned from Madeira to take his place at College. Will visit the Herschels before they set out for the Pyrenees.
Sends details of the progress of erecting the equatorial. William Mann is engaged on the Simon's Bay tide observations. The Madras Observatory post was offered to Mann but he declined it for health reasons. Comments on the affairs of [George Smalley], who is in financial difficulties. Not much news from the Cape. Comments on some of the educational news.
