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.
Inquires about appropriate person to add to the Cape Observatory staff, if FB can persuade the Admiralty of the need. Thanks JH for his comments on chloride of silver; were much better than W. H. F. Talbot's.
CG (Lord Glenelg) raises questions about the suitability of Mr. Train for a position teaching in the government schools at the Cape of Good Hope.
Mentions visit of 1 Feb. 1839 from W. H. Fox Talbot. Reports that JH has now 'accomp[lishe]d the whole problem [of photography].' Describes JH's recent results.
More about paper being published in both the R.S.P.T. and Athenaeum.
Further observations on the alterations at Cape Town Observatory. Any news of the measuring bars?
Sends HS's observations of magnetic declination and dip near London for forwarding to Carl F. Gauss. Encloses a letter from Edward Sabine.
Questions JH's intent to display 'photogenic drawings' to R.S.L.
Discusses own efforts in meteorology. Must wait to print second edition of work on storms. Appreciates nomination for R.S.L., but has little time for such pursuits.
Asks JH to keep him updated on English research of the dynamics of light. Currently considering the 'propagation' of light waves, as distinguished from their mere 'preservation'; asks whether this is a new study.
Considerable comment on procedure for submitting paper to R.S.L. Urges WT to mention JH's method of washing with hyposulfite. Comments on some photographic experiments of WT.
JH welcomes WT's mentioning JH's method of fixing with hyposulfite. JH has put some of JH's images on display at R.S.L. Mentions JH's recent experiments relating to photography. Comments regarding a paper submitted to R.S.L. by WT and on some experiments of WT.
Has a few pounds surplus from the subscription for JH's vase and wonders if it could be used to supply a plinth for the pedestal. Does JH agree? Perhaps Lady Herschel can supply the wording.
Wants to withhold description of 'developing' process until it is perfected to obviate others using it. Also refers to second process to make 'positive' and 'negative.'
Asks permission to use information from JH's letter in Astronomische Nachrichten. Believes [Alexander von] Humboldt can explain observational anomalies that JH notes.
JH will as WT requests stop mentioning JH's hyposulfite fixing process and await publication of WT's process. Reports in detail on some of JH's experiments relating to photography and to spectrum analysis. [In a P.S. dated 1839-2-13,] JH states: 'I have discovered your secret of fixing [or its] equivalent.'
In reply to WH's 1839-2-8 inquiry, JH believes that 'Skotodynamics' (the propagation of light waves) is a new line of research. Caroline Herschel is ecstatic about her Royal Irish Academy medal.
Saturday's experiments have brought a severe inflammation of the eyes so has been unable to use the aerolite. Returns it, but will try some experiments later if JH sends it back.
Thanks WS for his pamphlet on the 'Statistical Zoology of Britain.' Comments on the dynamics of animal and plant ecology.
Some comments on JH's light and photography experiments, especially effects of different kinds of glass and fixing with ferrocyanate.
Sends JH pamphlet on intimate connection between a country's zoology and its political statistics. Regrets that JH wished not to be nominated for presidency of R.S.L. on returning from Cape.
