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.
Tells AB about the state of education in South Africa when JH was there, comments on his part in such reforms as were made, and gives all the credit to Sir George Napier.
Further discusses the translation of [Alexander von] Humboldt's Cosmos [see RS:HS 15.207].
Discusses use of 'force' versus use of 'power' in translating [Alexander von] Humboldt's Cosmos. Says science has outgrown 'force.' [See 1847-10-8]
Thanks AQ for package No. 32. Asks AQ to acknowledge receipt of JH's Cape Results. Commends AQ for outstanding work on magnetic meteorological and periodic phenomena.
Communicates with others JH's choice of name for new planet [Iris]. Sends position of Hawkhurst Church tower obtained from map department. Describes rainy-day eclipse and reactions to it.
Thanks WH for 'plan' of [asteroid] Iris. Family is happy to have WH's son (JH's son William's friend) with them for holidays. Recounts their playful and adventurous activities.
Has dealt with the problem of thanking H. C. Schumacher [see GA's 1847-10-6].
Gives information from W. R. Hamilton on the location of the asteroid Iris. Proposes R.A.S. begin collecting observations of sunspots, the goal being a complete series of 'the sun's aspect for every day of every year.' Offers the observations of H. Griesbach for 1846 as a 'nest egg' as well as some of his own. Requests address of G. Schwinck, who prepared a star atlas. Reports on F. G. W. Struve's Neptune observations.
Hopes JH will attend the November R.A.S. meeting to stress the importance of recording solar observations [drawings of sunspots]. On J. R. Hind's work. Says Hind is not strong enough for the work he gets through. Cannot find G. Schwinck's address; suggests contacting H. C. Schumacher.
JH expects that CH has received the copy of his Cape Results that he sent recently.
Describes the funeral of James MacCullagh; mystified why he committed suicide.
Clarifies the agenda for the next R.A.S. meeting, and reports that the large refracting telescope is on the way to the Cape.
Is prepared to report on GA's trip to see Pulkowa Observatory, if JH does not need the meeting time [see JH's 1847-10-28].
The equatorial on the Dublin Observatory dome needs improvement. In the last fifty-two months, WH has seen three new planets: Neptune, Iris, and Flora.
WH notes that quaternions derive some interesting results in problems with three moving bodies.
Thanks WS for copy of W. S. Jacob paper on American telescope. Hopes that Jacob will attempt Talbotypes of sun spots while at Aden.
Concerning the method of observation by direct and reflected vision.
Regarding H. C. Schumacher and the intended distribution of J. J. F. Lalande's catalogue.
Did he see the eclipse? Agrees with him over the H. C. Schumacher proposals.
Regarding the forthcoming meeting. Concerning the telescope used at Pulkowa.
