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.
A note about forwarding papers related to the double star question [see JH's 1849-4-9].
Returning papers of Yvon Villarceau and an abstract of them, together with comments on them.
Has passed YV's memoirs on the calculation of orbits on to G. B. Airy for publication; copies will be sent [see YV's 1849-4-1]. Notes that YV's methods are similar to those of U. J. J. Leverrier.
Extended comments about some of GA's statements in GA's abstract of Yvon Villarceau's papers on double stars [see GA's 1849-4-11].
Identifies the positive features of the aneroid barometer as in use by the Navy.
Is thinking of withdrawing his son from Christ's Hospital owing to his frequent epileptic fits. Should he inform the Prince Consort? Outlines his recent photographic work.
Since writing to JH he has taken medical advice and decided to leave his son at Christ's Hospital for the time being. Gave a lecture at the Royal Institution on Friday evening.
Regarding tides in the atmosphere. Suggests a possible way of measuring these tides. Has never seen the subject mentioned.

Approves of James Nasmyth's application to join R.S.L. Describes good points of Nasmyth's telescope. Supposes that if he had drawing talent, he would sketch the members of the R.S.L.
Describes usual method for interpolation of altitudes at sea. JH's graphic method probably would be practicable.
Is sending a communication to JH for insertion in the R.A.S.M.N. Seems to be some problem with understanding YV's calculations of the orbits of double stars, so YV explains his method.
Is looking forward to receiving a copy of JH's Outlines Astr.; describes an aurora AP had seen at Alnwick Castle.
Sends extracts from book by Mr. Hopkins on the solar system. Has his own theories on the Augustan calendar proved to his own mind. No authority for giving the name Saras to the period of 223 lunations.
Is grateful for his Outlines Astr. Comments on its quality and usefulness. Sends the first report of the Board of Mathematical Studies.
Regarding the possibility of a new edition of JH's Treatise Astr. originally published in Lardner's Cyclopaedia. Has found it very useful for his students.
