Will give him great pleasure if he can assist J. Parkhurst in any way, but regulations in Messrs. Green's ships will preclude him from their service. Met Margaret Brodie Herschel at the Stewarts a few days ago.

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.
Will give him great pleasure if he can assist J. Parkhurst in any way, but regulations in Messrs. Green's ships will preclude him from their service. Met Margaret Brodie Herschel at the Stewarts a few days ago.
Giving observations of a new star observed by him and some of his correspondents.
Comments on new star reported by WH [see WH's 1866-5-18]; includes diagram of that portion of the sky.
Much obliged for his observations of June 1842. Probably the same star that is now being observed. Gives observations sent him by G. B. Airy.
Found the enclosed in a bookseller's shop, found it amusing, and sends it to JH to explain the mystery.
Comments on EH's 'Magic pictures', which JH said he produced and described in a paper twenty-six years earlier; JH is however unable to explain the process chemically.
Mostly about arranging a meeting with both JW and G. B. Airy at the Greenwich Visitation.
The packet for Wilfred Heely has just been delivered and JM will arrange for it to be forwarded to Calcutta by the Mail steamer.
Tells JH that JS's brother, James, is very ill and infirm, almost blind and with his memory failing, but wishing to be reconciled to those with whom he was in conflict in earlier times. Charles Babbage has visited. Would JH come or write?
Writes a very kind letter, encouraging JS to remember the good days when JS and JH worked together in astronomy, and to forget less happy events. [This letter was enclosed in JH's 1865-5-31 to John F. South.]
As JH rarely comes to London. and is himself in poor health, it is unlikely that JH can visit James South. JH wants, however, also to wipe bitter recollections from his mind.
Need to meet to discuss the question of publishing Charles Rümker's star catalogue [see JH's 1866-4-20].
Comments on Charles Rümker's observations and agrees to a meeting [see John Wrottesley's 1866-5-12].
Responds to meeting arrangements [see GA's 1866-5-24].
Thanks JC for his papers on 'ice-cap and eccentricities [of planets].' Comments on the papers, noting the interactions between geology and astronomy.
Comments on excellence of the lecture at the Royal Institution of JH's son [Alexander].
Wishes to ascertain certain facts for article on history and aspects of photography. Especially, asks where to find first record of JH and [Louis] Daguerre using hyposulfite of soda for fixing photographs.
Thanks JH for helping to clarify origins of Louis Daguerre's use of hyposulfite of soda for fixing photographs. Provides further information on photography, particular solar microscope photography.
In response to a letter from JH [RAS Monthly Notices, 26 (1866), 299-300] giving eye estimations of magnitudes of stars about Epsilon Coronae, suggests that the star JH observed may be 'the new variable' [T Coronae]. Reports Greenwich observations of this new variable star.
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.'
