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 been put (with GA and W. S. Stratford) on a B.A.A.S. committee to publish the J. J. L. Lalande and the N. L. Lacaille star catalogues [see GA's 1842-11-7]; sends draft request for a grant.
Proposes a plan for the distribution of printed copies of the star catalogues [see GA's 1845-7-25].
Believes he has worked out the German notation of star positions [see GA's 1847-2-1].
Uses GA's comments [see GA's 1847-5-10] finally to achieve clarification of Thomas Henderson's calculations.
Has dealt with the problem of thanking H. C. Schumacher [see GA's 1847-10-6].
Is still working on the distribution list for star catalogues [see GA's 1846-11-19].
Encourages GA to make requests to ensure that the Royal Observatory instruments are first rate [see GA's 1855-10-24].
Thanks GA for his description of Madeira; JH will try to get to Greenwich next day.
Asks GA if he knows of any rules or pitfalls in calculating time from earlier times [even B.C.] to the present.
Needs a good artisan to construct the framework of a solar spectrum photographic apparatus.
Arranging with GA for the provision of regular R.A.S. publications to be supplied to a foreign member.
Would support improvements, both in number and quality, of lunar observations at the Royal Observatory; current practices produce unacceptably large predictive errors.
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.
Extended comments about some of GA's statements in GA's abstract of Yvon Villarceau's papers on double stars [see GA's 1849-4-11].
Seeking information to help JH prepare an obituary notice, for the R.A.S., of F. W. Bessel.
The books are on their way [see GA's 1847-3-30].
Will be happy to supply a copy of the Cape Results [see GA's 1847-9-27]; the next asteroid should be called Flora, to provide 'young goddesses for Mars and Jupiter to admire.'
Has sent an R.S.L. membership application certificate for GA to sign and send on.
Suggests reducing the number of Greenwich astronomical observations printed, but not reducing the magnetic and meteorological observations.
