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.
Must rearrange date of sitting for HP's preparation of a portrait of JH.
Encourages WS to spend time observing nebulae and double stars, especially the latter, 'since [James] South has given up observing, and [W. R.] Dawes is in habitual ill health.'
Postpones visit of Lady [Margaret] Herschel to CW. Wishes to take CW's Symphonion to Slough. Has made favorable mention of CW's tuning fork experiments in paper on absorption [JH's 'On the Absorption of Light by Coloured Media...'].
Reports observing curious depositions of ice around the decaying stems of vegetables during frost. Speculates on the possible source.
JH reports the birth of his son William James Herschel.
H. W. Pickersgill proposed to paint JH's portrait for free, to be given to St. John's College. Now finds JH must pay for picture. Will delay until another artist is chosen.
Expresses some concerns about the proposed painting of his portrait [see WJ's 1833-1-1].
Thanks for sending results about conical polarization and introductory lecture on astronomy communicated through Francis Beaufort. Had hoped to send WH JH's yet to be printed catalogue of double stars.
Unsatisfied with H. W. Pickersgill as the person to paint JH's portrait. JH wants to consider further what to do.
Has sought, and is agreeing with, advice given about JH's involvement with several trusts [?] during JH's time in South Africa.
Congratulates JF on obtaining, after some difficulty, the Chair of Natural Philosophy at Edinburgh. Accepts offer to discuss meteorology with JF's relation Leslie Melville[?], and hopes to mention his actinometer.
Shocked to read in paper of HK's loss. Offers condolences.
JS is most welcome to visit Slough to see new baby [William James]. [Margaret Herschel note: Invites JS to christening.]
Will write [J.-B.] Biot, but does not know to which enquiries Biot wishes JH to respond. Also wants to thank Biot for his kindness. S.-D. Poisson in a statement before the Académie des sciences has misdescribed JH's planned voyage.
The observational data from FS regarding Gamma Virginis are so significant that JH begs FS to continue to observe and send JH the results. Comments on a number of other astronomical observational matters.
JH preparing for his journey to Cape Town. Compiling a catalog of nebulae and clusters. Sending to CH a comparison of a new set of elements of Gamma Virginis and a set of observations of it from 1720-1833; JH asks CH to send a copy to Carl Gauss.
Gently rejects MP's offer to accompany JH to the Cape to act as JH's assistant. JH claims the voyage to be a 'pure family party of pleasure,' and if astronomy can not be well practiced at the Cape, the family may go on to India to visit the relatives of JH's wife, Margaret.
Has received payment from [John] Murray [for review of Mary Somerville's Mechanism of the Heavens ?]. Cannot answer Mrs. Somerville's question about poles of maximum cold.
Thanks EC's for EC's observations made with EC's excellent telescope. Discusses Eta Coronae, Gamma Virginis, EC's drawing of M51, and whether Orion changes, stating that JH is 'no believer in rapid changes in Nebulae yet there may be changes....'
Asks GS to provide hospitality to J. C. Stewart, who is traveling through Italy. Sent package of books. Hopes GS will write to JH at Cape of Good Hope.
