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.
Encloses note about transportation of rockets, telescope, and chronometer, with suggested schedule for experiments.
Invites to dinner. Will try to arrange meeting between ES and Danish hydrographer Captain Lahrtman[?].
Sends plans for and detailed explanation of device to suspend cot or couch in ship so as to 'destroy' ship's motion and alleviate seasickness.
Mentions cirrus cloud formations foreshadowing aurora. Is unable to attend R.S.L. committee meetings and concerned that 'outlying' members be able to relay opinions through letters.
Had hoped to attend ES's soiree, but has influenza. Praises ES's report on Mr. McClintock's magnetic observations at Port Barrow.
Clarifies role and methods of R.S.L. Council and scientific committees, suggesting that members of Physical Committee need to be better informed about its activities.
Gives reasons for and discusses technicalities of supporting pendulum experiments at astronomical and geodesical stations in Indian trigonometrical survey.
Regarding report on magnetic observatories to be laid before R.S.L. president and council.
ES has been forwarded letter explaining why 'great telescope' at Melbourne will not work and suggesting construction corrections, on which JH, who believes such 'a priori condemnation' unjustified, comments herein.
Encloses letter on and discusses extent of government aid for proposed Hammerfest magnetic observatory and various alternatives with regard to it.
Thanks to [Francis] Ronalds for supply of paper. Comments on ES's discovery about direction of change in earth's magnetism, relating it to sun's and other electric currents. In this light, discusses auroras. Mentions abolishing of R.S.L. scientific committees and possible successor to John Caldecott.

Approves of ES's actinometric methods, but wonders about absorbent power of alcoholic liquid. Laments 'sad conclusion' to career of 'Hansa,' and hopes her companion is more successful.
Discusses significance of Col. Napier's pendulum observations to research on earth's constitution and gravitation.
On what is to happen at the expiration of a three year period assigned for the undertaking of certain magnetic observations.
Comments favorably on report by W. R. Birt on Kew meteorological observations. Sees special significance concerning atmospheric electricity.
Encloses differences determined through indications of portable barometer, standard, thermometer, and various other instruments.
