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.
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.
Sends along Frederik Kaiser's observations of Halley's Comet; [Robert] Everest is upset with JH because JH had signed a letter of support for a grant for T. B. Jervis.
Looks forward to the possibility of a visit from RJ.
Invitation from the Local Council to visit Cork for the B.A.A.S. meeting.
Regrets he will be unable to visit Cork for the B.A.A.S. meeting, but is conscious of the honor of the invitation.
Sends a paper of his brother, Christopher Kemplay, on a theory respecting comets. Has already submitted it to James Challis, who objects to some points. Would be glad of JH's comments.
Sending a letter he has received from a friend regarding a curious observation of the moon. Has seen the comet and encloses diagrams of its position.
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.
President of the Società Italienne des Sciences has received the invitation for members to attend the B.A.A.S. meeting at Cork. Regrets the length of the journey prevents members attending, but have nominated Michael Faraday to attend.
Sending details of a singular appearance in the heavens on 16 June.
Urges doubling number of lunar observations.
Is happy to hear that JH approves of the suggestion to send his eldest son to seek his fortune in the East. Will request that the appointment be conferred on William Herschel [JH's son]. Is spending some days with the Bryants.
Hopes that JH will maintain the road from the canals to Hawkhurst as SM possesses a right of way over it.
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.
About the health of Caroline Herschel, and other news from Hanover.
Would like JH to peruse HM's work and publicize its considerable use to Robert Graham.
WM is not the first person to write to JH on the application of photography to astronomy. Comments on the question and gives some of his own views on the subject.
Reports on GM's health and immediate travel plans.
Gives his own ideas concerning the origin of diamonds and would like JH's comments. Would also like JH's views regarding the phosphorescent light that plays at night over the magnesite excavations.
