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 published a pamphlet on the True Figure and Dimensions of the Figure of the Earth, which he sends for his comments. Has had no success with G. B. Airy. Has found an error in J. F. Encke's work on the comet.
Thanks for his frank statement on his pamphlet, but would like his opinion later when he has studied it more thoroughly.
James Glaisher has made two more balloon ascents and reached six miles high. W. R. Birt has been observing at Hartwell during the present lunation and discovered several new spots, a sea, and craters. Sends details. Is sending a petition to H. J. Temple (3rd Viscount Palmerston) for a pension for Birt and would be glad if JH would look it over and sign it.
Further to publication of JH's work [see GS's 1862-8-28 & 1862-8-12].
Note accompanying proofs of a contribution by JH to 'Survey of Literature, Science, and Art'.
Note accompanying some material being returned to JH.
Confirms through personal experience a passage in JH's Physical Geography regarding an 1860 earthquake.
Is grateful for the ? which made him laugh. Hopes that Lady Herschel will accept the enclosed.
Regarding the pictures of the moon by M. M. Gussew. Gives details of the eclipse of 1860. Heliograph has been working at his observatory since February. G. Sabler has now left and will doubtless do good work when he receives his instrument from J. H. Dallmeyer.
Sorry to hear about JH's pain. Encloses notes from GA's testimony to parliamentary committee investigating changing standards of weights and measures. GA's work continues on 'veritable precessions.'
Encloses letter from G. J. Stoney, who had journal of WP's nebulae observations. Hopes WP's observations will be helpful for JH's proposed catalogue of nebulae.
Delighted with performance of WL's telescopes in Maltese climate. Invites JH to visit. Awaiting JH's catalogue of nebulae. Seeking assistant.
Describes galaxy-like gaseous nebula with interior elliptical ring.
More about the nebula catalog JH is preparing [see HA's 1862-3-12], and still wondering if there is some way HA's observations might be used.
