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.
Believes he has discovered a second satellite of Neptune; gives readings.
Humphrey Lloyd wants R.S.L. and B.A.A.S. committees on magnetism to meet together at B.A.A.S. meeting in Leeds. JH suggests inviting Edward Sabine.
Informs JH that GA (and his assistants) have been making pendulum observations in a coal pit.
Sends on announcement of 'new planet Parthenope' from Annibal de Gasparis at Naples.
Acknowledges receipt of JH's 1850-5-28; GA will pass on the news to some others.
Details of how coins are tested and stamped for weight. Procedures are not regulated, and variances are common. Encloses Mr. Miller's letter on decimal coinage. [JH annotation: 'Substance sent to Airy March 21 / 53 but altogether diff in form and wording.']
Thanks GA for a letter of introduction to friends in Rome [used by JH's daughter Margaret Louisa and her new husband, Reginald Dyke Marshall]; JH is willing to serve on a committee with GA and others if he does not have to go to London for meetings.
Suggests GA alter some phraseology and tone in his response [see GA's 1858-5-4] to Edward Sabine's report on magnetic observatories.
Agenda items for 2 Mar. 1853 meeting of Commission for Restoration of Standards of Lengths and Weights.
Intends to set up a meeting with appropriate members of the B.A.A.S., in order to prepare presentation about magnetic observatories for the B.A.A.S. meetings in Leeds.
Asks GA to help in determining cost of one observation station in Peking [see Richard Owen's 1858-12-18].
Given the Treasury stance [see Richard Owen's 1858-12-18], GA sees little point in setting up one station [see JH's 1858-12-18].
Writes to inquire as to the whereabouts of the Richard Sheepshanks's papers [see GA's 1851-11-25].
Would like the brief version of Richard Sheepshanks's paper to send to William Parsons.
A notice of meeting of the Standards Committee.
Is asking JH to bring the long version of Richard Sheepshanks's paper to the next meeting of the Standards Committee [see JH's 1852-2-11].
Agrees with JH's idea of decimalizing the pound weight, but the stone should not then be used [see JH's 1852-3-5].
The standardization of weights and measures is moving ahead; the question of storage of standards must be addressed.
Has heard that one of JH's daughters [Amelia] has been hurt by burning; expresses concern.
Expresses unease about P. S. Laplace's formulation of the barometric determination of height; in a postscript comments that Michael Faraday's lecture on conservation of force is a 'strange production.'
