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.
Acknowledges with pleasure JH's kind note. Owes much to JH's book in the chapter on experimental methods. JH will doubtless find Auguste Comte's book worth reading. Would like a note of any errors in JM's book.
Urges JH to study a temporary index made by William Herschel that contains observations about types of zodiacal light.
Wishes JH had added his name at the head of the list of subscribers. Thinks he is being too cautious. AJ is responsible for the whole of the work though it appears under two authors.
Has been able to obtain some deodar seeds from Ireland. Sends them, together with some seeds of the Himalayan cypress. Hopes they will prove a success.
Thanks JH for earlier letter. Discusses JH's work on chemical action of light, with which he is familiar. Sends some papers for JH's comments.
Sends comet observations from W. S. Jacob. Obtains 'another excellent epoch of Gamma Virginis.'
Regarding Captain [Charles ?] Gray's letter. Robert Peel has written asking Francis Baily and W. H. Miller to do the 'Standards.'
Recommends a method for destroying wasps' nests. Refers him to the Gardener's Chronicle for information on flowering Cape bulbs. Has no idea where he can obtain deodar seeds. Would like to see his paper on the influence of light on vegetable colors.
Francis Beaufort to publish comet information; also wants JH's opinion as to what data should be sent to Cape Observatory. James South will lecture at Royal Institution. South's requests for several historical astronomical instruments refused.
Regarding JH's answer to his own paper on the revision of the boundaries of the constellations.
Hopes that JH will maintain the road from the canals to Hawkhurst as SM possesses a right of way over it.
Can JH come to the congress on Friday?
Thanks JH for his letters about the Cape equatorial instrument.
Received a stray dispatch, dated at sea, from [James] Ross. Assumes Ross is on his way home.
Has invited some astronomical friends to the meeting on Friday.
A note accompanying a new book on etymology and requesting JH comment on it.
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.
Sending some pages from the Mechanics Magazine containing details of clock escapements, superior to those at present in use.
