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.
Has invited some astronomical friends to the meeting on Friday.
A note accompanying a new book on etymology and requesting JH comment on it.
Encourages AE to consider translating some mathematical works; additional comments on mathematics in general.
Has just heard that JH would like some deodar seeds; so he encloses some. Could also supply some young plants if he would like them.
Thanks for the deodar seeds sent; accepts JL's offer of some young deodar plants. Needs instructions on planting these. Does JL have a copy of JH's 'On the Action of the Rays of the Solar Spectrum on Vegetable Colours, and on Some New Photographic Processes'?
JH sends some examples of a unique kind of latent photograph, and adds other comments about various aspects of photography. JH has seen a good aurora. He now agrees with A. C. Becquerel's theory of the spectrum.
Twelve deodar plants are being dispatched by coach. If JH plants the seeds now he should have nice young plants by the autumn. Would be obliged for his paper on vegetable photography.
Sending some pages from the Mechanics Magazine containing details of clock escapements, superior to those at present in use.
