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.
Writes to announce the birth of JH's and Margaret's first daughter, Caroline Emilia Mary.
Asks help in summarizing scientific labors of her late husband, Thomas Young, for memoir by Hudson Gurney. [Addressed to 'William Herschale, Esqr.']
JH agrees to assist Hudson Gurney in writing biography of Thomas Young. Please send catalogue of Young's works. Ask Hudson Gurney to write JH.
Does not wish to see HG's biography of Thomas Young until its publication. Anything JH submits must remain unaltered, with JH's name attached. Will not give reasons. Requests copy of Young's article 'Tides' in Encyclopaedia Britannica.
Send Encyclopaedia Britannica volumes with Thomas Young's article on tides and T. R. Robinson's article on sound. When will HG's [biography of Young] be published?
Thanks NB for sending volume I of NB's translation into English of P. S. Laplace's Mécanique céleste. Praises the translation and notes that it shows the high level of science in the U.S. Will send NB some of JH's publications.
Thanks for his letter, which had been forwarded to his old address. Is pleased he intends working on double stars, though 70 Ophiuchi may prove difficult. Will send some of his own readings for double stars. Like him, he is astonished at the acrimony of the attack on Thomas Young and the Nautical Almanac.
Sending a letter he has received, and would like JH's opinion on it [probably about his telescope; see P. Barlow's 1830-3-14].
Suggests Peter Barlow should test his telescope by carrying out a series of observations.
Thanks JH for criticisms of her manuscript. Will outline principles more carefully. Hopes Lady Herschel is 'gaining strength.'
Sends first revised pages [of MS's Mechanism of the Heavens] back for further opinion. Highly respects JH's comments and believes he will be a truthful critic as a friend.
Sends new translation of [P. S. Laplace's] Mécanique céleste. Says her revision [of MS's Mechanism of the Heavens] has been effective. Still doubts the derivation of the fundamental equation. Discusses force, resistance, and reaction with regard to this equation.
Thanks JH for his communications. Anxious to get into the proof JH criticized. Sends [Joseph] LaGrange's variations of constant quantities.
Says manuscript [Mechanism of the Heavens] cannot be improved materially except perhaps on one or two small points. Will look at it again when it is together in a whole. Announces birth of JH's daughter [Caroline] that morning.
