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.
Would like FH to study a phenomenon that JH has noticed on the sun's disk and that has no connections with sun-spots.
Proposes to travel to visit FH next day to observe the sun with him.
Thank you for his letter. There are no misprints or conflicting statements in his Familiar Lectures. Explains the various points.
Returns his Australian friend's speculations. Comments on these theories regarding atoms, etc., and gives other books and articles showing that his theories are not unique.
Agrees to allow Lord Oxmantown [Laurence Parsons] to add JH's remarks to Lord Oxmantown's paper.
Comments on UL's paper on meteors. Outlines the nebular theory of the solar system.
Does not think Mr. Thornton's pamphlets solve the problem of squaring the circle as the circle is 3/4 of the circumscribed square. Comments further on these theories.
Cannot supply testimonial as he has no knowledge of any other of JM's writings, nor does he know him personally.
Concerned about 'Commercial weight' of new standard of weights and measures.
Advice on choosing executors, drawing will, and disposing of MB's property. Sends semiannual dividend from Drummond's.
Alterations to MB's will. Objects to MB's plan to return to live in Mr. Binsted's house at Anstey.
Gives more reasons for objecting to MB, 80 years old, leaving Stubbington and moving to Anstey [see JH's 1867-2-10].

Describes JH's theodolite by G. F. Reichenbach and offers to loan it for PB's survey [of Sinai Peninsula].
Suspects that discrepancy between old and new commercial weights of Standard Pound may be due to trapped air in new standard. Needs WM's reply soon, so JH may inform India Committee on weights and measures.
Discusses WM's reply regarding commercial weight of new Standard Pound.
JH is busy correcting first proofs of pages on double stars. Thanks for binding JH's star [allineations?]. CP's suggestion [see CP's 1867-3-27] to JH's son Alexander, to collect and edit William Herschel's papers, entails too much work for one editor. JH dreads thought of such work. Doubts CP's claim that WH observed fixed star in Corona.
