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.
J. T. Boileau and L. E. O. Ludlow were appointed by H.E.I.C. to direct Indian observatories. R.S.L. is concerned that it has no choice in selecting directors. Instruments for H.E.I.C. observatories. Should JL request additional staff for all 16 observatories, or only for nine permanent ones?
Has he succeeded in obtaining a Daguerrotype for J. C. Ross? Thinks one or two would be desirable. Has got one himself and obtained good results. Two of his family are ill, which brings him to town. Hears that JH has got colors, which is a great step.
