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.
Responds to meeting arrangements [see GA's 1866-5-24].
A note to accompany forwarding of papers and letters relating to Charles Rümker's observations [see GA's 1866-5-31].
Did not realize [John] Hennessey was considering constructing an achromatic telescope. Thanks ES for considering his son, Alexander, for the Melbourne post.
Has heard about William Whewell's accident. Hopes he will recover, but knows his advanced age may hinder this. Wishes WS to send news of progress.
Thinks William Whewell's excitement may be a 'precursor to exhaustion.' The hope of recovery is very slight. JH is interested in Whewell's article on Plato.
Thanks WS for communicating the events of William Whewell's last days.
Discusses how to denote the positions of the celestial bodies in solar photographs. Advocates a system that shows differences of heliocentric longitude on the sides of the sun.
Helioautographs are beautiful. Advises keeping original plan for presentation. Says 'Clarke's' [Harvey Carlisle's] article on William Whewell in MacMillan's is satisfactory. Describes an 'absurd paragraph' regarding Whewell in François Moigno's Mondes.
Says the plan for the exhibition is ingenious. Discusses the 11 year cycle of sunspots and says the sun was spotless the previous day.
Congratulates WS on his recovery. Thanks him for the meteor observations. The evidence points to an 11 rather than a 10 year period [in sunspots?].
Thanks JC for his paper on the 'Influence of the Tidal Wave on the Moon's Motion.' Expresses disagreement with a number of aspects of JC's argument.
Thanks JC for his papers on 'ice-cap and eccentricities [of planets].' Comments on the papers, noting the interactions between geology and astronomy.
Thanks CP and R.A.S. Council for funds to help with JH's catalogue of William Herschel's double stars. Alexander Herschel will begin work soon on the project.
Thanks for remarks on early portions of JH's Iliad translation. Hopes MA can go over 2800 particularly 'shaky' lines.
Reports on paper [R.S.P.T., 156, 181-] by [William] Huggins on spectra of certain nebulae with mode of determining their brightness. Doubts some presuppositions, but regards paper as fit for publication in R.S.P.T.
Describes experiment involving viewing spectrum of a light flash as it advances and recedes. [Marked 'not sent on further consideration.']
Maintains that a first class refractor is not needed at Masouri in India [see ES's 1866-9-4]. No special characteristics there justify the great expense of such a project.
Thanks for note [see JT's 1866-5-26] on improvement of the lecturing style of JH's son [Alexander]. JH's son has studied lecture's subject deeply and loves science; JH hopes will be physics professor at a 'considerable institution.'
RM has inadvertently sent letter intended for 'S,' a chemist, to JH. Having read letter, JH comments that he esteems 'S,' but thinks it advisable to tell 'S' that B.A.A.S. as a body will not recommend 'S's invention to government.
Describes the problem of 'probability of three points on a plane forming an acute triangle.' Notes Augustus De Morgan has the same solution to the problem.
