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.
On Friday the compensating bars will be embarked for the Cape; William Mann will be in charge of them at the Tower. Dr. T. R. Robinson is anxious to have some of the instruments from the Kew Observatory; does JH know how they may be obtained? Regarding an actinometer made by Robinson.
Encloses two meteorological reports of J. A. Lloyd (who has been ill with fever), and a paper of Dr. T. R. Robinson.
Is dismayed that Thomas Maclear is unable to obtain manual assistance at the Cape for the compensating bars. Bars were shipped on Friday. Next time JH passes the Admiralty he will show him the debris of the actinometer.
Would like his opinion on whether an officer should be sent to the Cape to be in charge of the compensation bars sent there recently by the Board of Ordnance.
Is forwarding a note about an instrument of [Louis] Daguerre's.
Sending a letter of Basil Hall's, which please return when he has read it.
Enclosing letters from Thomas Maclear so that he may see all he says about his meteorites. Will keep the meteorite until he tells him what to do with it.
Thomas Maclear has sent him another Cape meteorite. Believes that JH gave part of a meteorite to the B.M. so does not see why this one should be sent there.
Sends hourly meteorological register for 21 Sept. in Bahama Islands. [Partial sentence about] Equipment reaching J. C. Ross at Madiera.
Enclosing a page and a drawing, which may be of interest to him. Best wishes for Christmas.
Thanks for sending him the requiem.
Sending him the last Comptes rendus that can go by post. Hopes he can arrange some other method. Is always pleased to receive his publications.
Encloses seven notes from J. C. Ross to Edward Sabine and FB.
No objection to JH publishing soundings of J. C. Ross. FB will send JH detailed records of these. Any letters to Ross must arrive by 18 June for dispatch to Hobart Town. FB has copies of Thomas Maclear's correspondence about magnetic observations.
Apologizing for the delay. Sends various map locations. Also extract from Captain F. W. Beechy's letter regarding magnetic operations.
Is preparing an estimate for Parliament and would like his views on the usefulness of re-measuring N. L. Lacaille's base, etc., at the Cape.
Is sending him Thomas Maclear's account of taking the field and of commencing his base operations.
Edward Sabine has asked him to forward J. C. Ross's notes. If JH has finished with Thomas Maclear's letter would he return it.
Admiralty wished to present him with another part of the Cape Observations, and will hold it until someone is deputed to call at the office.
Sends JH a copy of Thomas Maclear's base measurements, and will transmit JH's letter to Maclear.
