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 just returned from abroad and found his letter of April awaiting him. Hoped to visit Vienna when abroad. Has received money for the clock. Hopes to send his own paper on double stars later. Encloses some papers for distribution. Measured height of Etna when in Italy. Met Josef Fraunhofer and had an instructive discussion with him.
Anticipates appearance of JH's work on double stars; asks for suggestions for employment for a young man from Germany, and offers some suggestions about refining the study of refraction.
About books and papers, being sent both ways.
Bad weather has prevented him from observing the transit of the comet. Has purchased a refractor similar to the one at Dorpat.
About observing comets, problems with book sellers and shipping books. JL has written a popular astronomy in which he deals with perturbations, precession, and other difficult topics. Would JH like a copy?
Sends some additions to an earlier paper on object glasses of telescopes; also some observations of the August comet, made by other astronomers.
Has been overwhelmed with work, which accounts for the delay in writing. Thanks for communications. Both are now printed. Comments on some of the points raised.
Thanks for comments on JL's papers [see JH's 1828-7-24]; Charles Babbage had visited JL.
Is sending papers for the Astronomical Society Memoirs, on telescope lenses and the construction of telescopes, planetary observations, and the use of equatorial telescopes. Is anxious to see JH's writings on light and his nebulae catalogue.
Unable to be at Katers' home for dinner, but will arrive later. JH is pleased to find HK's and JH's measurements of Mars agree with those of JH's father, William, and compares these with some other measures.
Accidentally found some verses on a scrap of paper, and wondered if it would fit the music of Cherry Ripe; sends verses to MK.
Asks MK's permission to allow a close friend to make use of the words once sent to her by JH as suitable for the music of Cherry Ripe.
Confusion around [James] Grahame's possible use of the verses that JH had offered to MK as suitable for the music Cherry Ripe.
Had difficulty with actinometer observations on Etna, but obtained a few. Has just obtained a living in Somerset. Is working for the Encyclopaedia Metropolitana at the moment but hopes to make a set of actinometer observations soon.
Met Mr. Smedley a few days ago and the latter has the impression that JH is to write the article on Heat for the Encyclopaedia Metropolitana. Comments on this and wonders if he can request the articles from JH. Sends letter via Charles Babbage.
Charles Babbage communicated [Edward] Smedley's note requesting JH to write an article on 'Heat' and an Introduction to Physical Science. Appears to be some misunderstanding as JH does not wish to write on Heat, no interest in the subject, but is prepared to write on Physical Optics. When will the latter article be required?
Hears a letter from JH has miscarried. Anxious that JH should write an article on Heat as FL is too busy.
Concludes original letter lost. Impossible to do any further work for the Encyclopaedia Metropolitana. Hopes FL will write the article.
Their letters have missed more than once, and JH's last letter is now at the Return Office. Would like to see this letter to learn JH's views on the article on Heat. Gives own ideas how article should be written, too busy himself, so hopes JH can write it, or does he know any other person?
