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.
Suggests a resolution of a small amount of money having to do with the exchange of some chairs; also asks about a dining room table.
Outlines advantages of placing magnetometers for Hammerfest Observatory at Edward Sabine's disposal, so that he can instruct those going to Toronto and the Cape in their use.
Comments on additional proposals for consideration by the Standards Commission [see JH's 1841-3-20 or later].
Has been experimenting with paper prepared with light-sensitive vegetable juices. Sends two specimens of JH's results.
Does not expect to come to the meeting [see GA's 1841-5-18], but sends comments on altered sections of the draft report.
Is unable to come to London for the Standards Commission meeting and thus will also not be able to come to the dinner party. Encloses some recent photographs.
Thanks RH for his 'extensive and instructive view on the present state of photography.' Found many interesting results in experimenting with vegetable substances. Surprised by RH's discovery that bi-chromate of potash is a photographic substance; JH nearly achieved this result.
Has received the maps from John Arrowsmith and sends a blank check for FB to fill in correct amount to pay the bill. Is unable to attend the Standard Commission meeting. Hopes FB can visit him in the summer.
Believes no error should be legally tolerated [see GA's 1841-5-24] in selling goods; thus the seller always provides a trifle over the due quantity.
Thanks AD for his theorems; comments on the value of such abstract speculations.
