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 about partially white leaves and about droplets of water forming at the tops of leaves. Has been studying the effects of spectral rays on vegetable colorings.
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'?
[Responding to JL's 1844-12-30], declines JL's request that JH write a series of articles on meteorology, because of JH's need to work on the manuscript for JH's Cape Results. Hopes eventually to write on meteorology.
Is grateful for the flowers. The Satyriums are most interesting. Comments on the variations in this species.
Exhibited JH's gift of the Satyriums at the meeting of the Horticultural Society and he has been awarded the Banksian medal. To whom shall the medal be ascribed? Any further information on the orchidaceae would be very welcome.
Sends the silver Banksian medal for JH's exhibit of 16 Oct.
Is greatly obliged for the present of flowers. Has introduced another Herschellia into the world as he has used the name for a Disa.
Will be pleased to examine the dried plants. Send them to the Horticultural Society's Garden, Turnham Green.
Has opened the box of dried specimens, but they are unsuitable for his purpose as they are not flat. Suggests that King's College or University College may be a more suitable home for them.
Is working on horticultural considerations of Cape plants and would welcome information on the temperature just below the surface of the soil in relation to the temperature of the air.
Not much is known about the circumstances that affect the color of plants. JH's researches will be valuable if they throw any light on the subject. Comments on the various theories affecting the color of plants.
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.
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.
Wonders if JH could be persuaded to write a series of articles on meteorology for the Gardeners' Chronicle. If unable, could he suggest a suitable substitute?
