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.
About arrangements for the christening of daughter Caroline, and about the health of the family.
Has been laid up with a cold and unable to answer his letter. Congratulations on the new baby. Hopes mother and child are doing well. Will wait for confirmation of his son's marriage before sending the news to the papers.
Still making arrangements for the christening [see JH's 1830-4-15]; concerned that it should be done soon.
Has had a letter from Henry Foster regarding his pendulum experiments at Ascension.
Requests advice in determining optimal time for visit to England. Thanks for invitation to Slough. Mentions completion of his sixth volume of observations, the introduction of which could prove interesting to JH. Fascinated by JH's observation of a sixth star in the trapezoid of Orion.
Sending two volumes of her Fishes and explaining the reason for the delay.
Takes a moment to write. Sends various brochures and observations on magnetic intensity in Germany. Asks JH to give a copy of it to [Charles] Babbage and [Henry] Kater. Congratulates JH on being named correspondent to the Institute of France. Lost his father-in-law. Has asked [James] South to press construction of AQ's instruments, but no luck. Requests JH visit Edward Troughton and the instruments.
Sending a list of the stars to be observed to test the strength of his telescope.
Will send engraving of late husband, Thomas Young, to JH. Hudson Gurney nearly finished with memoir. When will JH be done? Wishes to announce biography of Young.
Tells AQ of 'negligent inattention' regarding Belgium's instruments. Has extracted promise from [William?] Simms that the equatorial should be finished by Christmas and mural circle within the following year. Mentions seeing Colonel Blake and [G. P.] Dandelin. Regrets [P. F.] Verhulst's illness. Discusses lichen.
Sending back part of manuscript [Mechanism of the Heavens] for criticism. Hopes Mrs. Herschel and baby are well.
Has received the R.S.P.T. Also comments on several chemical matters, including isomorphism and crystallization.
Announces second volume of translation of JH's Light is out in Paris. Is sending a copy. Work progresses slowly. Problems because of revolution. AQ's collaborator [P. F.] Verhulst is very ill. Will leave for Italy soon. Discusses his previous trip to Germany. Saw [William] Whewell. Has received Astronomical Society's memoirs.
Reports on good health and behavior of JH's new daughter, Caroline Emilia Herschel. Comments on Greek music and on recent results of the R.S.L. Glass Committee.

Thanks TH for some crystals, including borax, as well as a paper by J. J. Lister. JH has been cutting the borax crystals preparatory to grinding and polishing them; JH has used these crystals to observe a phenomenon previously seen with a mass of niter.
Sending a paper by J. J. Lister on the microscope and some crystals of Borate of Soda. Carlo Gemmellaro has been examining temperature of air in the subterranean passage near Nicolosi. Hopes JH will visit Tottenham; would give him great pleasure to see him.
About the prices of telescope mirrors, and specifically the one of T. J. Hussey; recommends use of certain stars to test the optical quality of the mirror.
