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.
Believes he has worked out the German notation of star positions [see GA's 1847-2-1].
Has figured out why [Thomas] Henderson's tables [see JH's 1847-5-6] appear as they do.
Reports that the RAS has an available balance of £77. He calculates that to complete the printing of J. J. L. Lalande's Catalogue of Those Stars in the Histoire céleste française... and N. L. Lacaille's Catalogue of 9766 Stars in the Southern Hemisphere, however, will require £83 pounds; WS hopes to cut costs so that they do not overspend their grant.
Asks CB's advice on how correctly to avoid attending a Queen's ball JH has been commanded to attend.
Concerning Thomas Henderson's reductions of N. L. Lacaille's observations.
Uses GA's comments [see GA's 1847-5-10] finally to achieve clarification of Thomas Henderson's calculations.
Sending to JH some information about 'L's catalogue' [either N. L. Lacaille's Catalogue of 9766 Stars in the Southern Hemisphere or J. J. L. Lalande's Catalogue of Those Stars in the Histoire céleste française....]
Although WS is suffering from gout, he promises to work on the layout of J. J. L. Lalande's Catalogue of Those Stars in the Histoire céleste française....
Congratulates JH on finding solution [to Thomas Henderson's notations]. Sends extract of 11 Mar. 1841 letter from Henderson, stating that Henderson used computations in Francis Baily's edition of N. L. Lacaille's catalog. RS's notes on observation and reductions of J. J. L. Lalande. Sent skeleton of RS's 'Preface' to W. S. Stratford.
Discusses the layout of J. J. L. Lalande's Catalogue of Those Stars in the Histoire céleste française....
About a time conflict involving the R.S.L. and Visitation Day at the Royal Observatory.
Asks JH for measures of several double stars.
A note enclosed with the printed observations made with the Northumberland equatorial telescope.
Has directed the printers, Taylors, to send JH's booksellers the parts of the Barometrographia as issued, free of all costs. The science of meteorology attracts little attention at the moment.
Believes that RS's suggested correction, 'when translated into its equivalent value in terms of the inclination,' will provide sought-for values.
JH's Cape Results is ready for publication. Gratitude for support of late Hugh Percy. Regrets HP did not live to see completion of Cape Results. Trusts that AP will continue support. Asks for interview. Encloses correspondence between HP and JH to show how arrangement originated.
Suggests JH visit tomorrow at noon.
Reports that the printing of J. J. L. Lalande's Catalogue of Those Stars in the Histoire céleste française... and N. L. Lacaille's Catalogue of 9766 Stars in the Southern Hemisphere (which includes a preface by JH) is 'progressing satisfactorily.'
A notice of meeting of the Standards Commission.
