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.
Sends a proof, which please return with the necessary alterations and additions. JH's daughter is quite well.
Has been looking at JH's treatise on meteorology, especially the part relating to the barometrical formula. It seems that JH missed JL's paper on refraction published in Transactions of the Astronomical Society, and is therefore not aware of the true nature of P. S. Laplace's atmosphere; comments on this.
Does not possess the Transactions of the Astronomical Society, which contains JL's paper. Had to limit the scope of his article so could not deal with the point mentioned in JL's letter. Comments on P. S. Laplace's formula.
About the barometric formula for the measurement of heights.
Of course JH is right; regrets he gave him so much trouble. Hopes his own construction of P. S. Laplace's atmosphere is correct. Hopes JH's daughter had a prosperous journey.
Acknowledges receipt of [JH's Cape Results].
JH's conjectures are natural but Augustus De Morgan had nothing to do with JL's Treatise on Probability. JL wrote it in conjunction with J. E. Drinkwater Bethune, although the title page does not show the names of the authors. Understands what JH means about the moon but cannot see what will be gained. Sorry to hear of JH's mishap.
