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.
Asks permission to include JH on R.S.L. committee, headed by C. J. Selwyn (relative of George Peacock) and Dr. Beale, to purchase portrait of Peacock from artist Douglas Blakiston. Self-recording magnetic instruments have reached Washington safely.
Will assist JH in preparing review of terrestrial magnetism. Progress in publishing vol. 2 of observations from St. Helena. Prince Albert favors new observatories and hopes to see JH [at B.A.A.S. meeting] in Aberdeen. Research in British colonies. Demonstration of Mr. Gossert's apparatus by [T. R.] Robinson.
A. D. Bache reports that self-recording instruments are installed at Washington observatory and ready to begin observations. ES is making field observations to confirm changes in magnetic lines in England since ES's 1837 survey. [JH annotation: Summary of Bache's letter. Joint survey by Smithsonian Institution and U.S. Coast Survey will begin when Bache receives full instructions from Sabine.]
Does JH wish to alter ES's reply to A. D. Bache? Origins of names for American rivers. Hopes JH is well enough to accept the invitation of Lord Aberdeen [G. Hamilton-Gordon].
Replied to J. A. da Silva that Kew Observatory would gladly train Portuguese observers and superintend manufacture of instruments, but that ES could not speak for English government. [JH annotation: Summary of letter from da Silva, director of meteorological observatory in Lisbon, requesting training for Portuguese observers at Kew, British influence on Portuguese government to join magnetic survey, and advice on instruments.]
Notified Richard Owen that Kew observatory is ready to receive trainees for magnetic observations. Stewart Balfour estimates six weeks to train observers, who will then take instruments and leave for British Columbia or Shanghai. New observatory at University of Mississippi in U.S. American Association for the Advancement of Science has expressed interest in magnetic survey. Success in photographing sunspots, which R. C. Carrington and Warren de La Rue will supervise. Recent observations.
Encloses ES's résumé of magnetic surveys accomplished by U.K., written to encourage similar surveys in China and North America. Perhaps JH may append this to JH's report.
Proper procedure for communicating with Charles Grey. Cost and effectiveness of self-registering instruments versus older visual instruments. ES's method of estimating observatory expenses. Importance of observatory in Shanghai.
Extract of letter from Charles Grey, asking B.A.A.S. to inform Prince Albert of estimated expenses for proposed five-year survey of terrestrial magnetism. As president of joint committee of B.A.A.S. and R.S.L., JH should answer this. Entry of three U.S. observatories may eliminate need for observatory in Newfoundland. Recent visit to Kew by A. T. Kupffer suggests that Russian stations may soon have self-recording instruments. Proposes suspending observatory in Falkland Islands until colonies decide to join survey. Dutch observatory in Java. Describes buildings needed for observatories. Estimates expenses for six years.
Announces meeting of Kew Committee at Observatory on 29 Aug.
Announces meeting of Council at Marishal College, Aberdeen on 14 Sept.
Shares JB's experiences with visual abnormalities similar to those described in JH's 'Sensorial Vision' (1858). Encloses copy of related subject that JB found in Section 45 of John Locke's 'On the Conduct of the Understanding.'
Sending CD's new book, The Origin of Species. Acknowledges CD's deep obligation to JH's Prelim. Discourse. 'Scarcely anything in my life made so deep an impression on me....'
Regarding JH's question about formulae for intensities of reflected light, BP encloses a paper concerning G. G. Stokes's conclusions about the direction of the plane of vibrations.
Has shown JH's son's letter to [C. E.] Trevelyan and encloses his reply. Affairs in India may become more dangerous.
About GA's plans to attend the B.A.A.S. meeting in Leeds.
Would be glad to accompany JH to Kew to see instruments.
Will travel to Kew Tuesday. Encloses answer to Duke of Newcastle regarding proposal for colonies. Welcomes any comments from JH.
Encloses letter from Colonial Office to R.S.L., which was referred to ES because [B. C.] Brodie was out of town. Brodie hopes to see JH when JH comes to London.
Discusses [Angelo] Secchi's letter. Can supply the Jesuits in Cuba with magnetic apparatus they need. Discusses Secchi's views on cause of earthquakes and volcanic eruptions.
