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.
Believes he has discovered a second satellite of Neptune; gives readings.
Has discovered two new satellites of Uranus; gives observations. Would JH suggest names for them.
Giving his recent observations of the satellites of Uranus. Has not detected more than four satellites.
Is well satisfied with the names JH has suggested for the satellites, but wonders whether the continental astronomers will accept them. Is puzzled by the orbits of two satellites.
Found he had made an error in his letter of yesterday. Encloses an amended table.
Intends to use JH's names for the satellites of Uranus in a communication unless JH has any objections.
Thinks the climate of this country is unsuitable for good observations and is thinking of setting up his telescope in Malta. What does JH think of this idea? Can JH provide an introduction to the Governor of Malta.
Illness has prevented an earlier reply thanking him for his introduction to the Governor of Malta. Expects good results in Malta.
Has been given every facility to erect his telescope in Malta. Atmosphere has been excellent for observations. Has studied the satellites of Uranus and the ring of Saturn; the latter is puzzling. Has been astonished with the views of Orion.
If the Herschels intend visiting the B.A.A.S. meeting at Liverpool he will be pleased to accommodate them.
Was indebted to JH for the names of the satellites of Uranus. Will find details of his observations in the R.A.S.M.N. Gives volumes. Is thinking of returning to Malta and erect a larger telescope.
Wishes all success to his proposed visit to Malta. Has been able to find the volumes of R.A.S.M.N. Comments on WL's system of levers for his telescope.
Thanks for his suggestions respecting the mode of observation by collimator; will give it careful consideration. Sends two photographs of the method of mounting his observation tower.
Is dismayed to find in the new edition of his own Outlines Astr. that he has attributed the discovery of Hyperion to W. R. Dawes without crediting WL; will have this corrected in a future edition.
Do not let the error in Outlines Astr. disturb him; he quite understands. The 4-foot telescope proceeds. The speculum has been polished and awaits trial. If JH is attending the B.A.A.S. meeting hopes he will visit Lassell.
Suggests names for the satellites of Uranus, in response to a request from WL [see WL's 1851-11-3].
Congratulations to WL on his discovery [see WL's 1851-11-3]; naming should occur once the various satellites have been described and verified.
Is willing to assist in obtaining letters of introduction for WL's projected trip to Malta.
Is preparing a new edition of Outlines Astr., and would like to know from WL the status of each of the satellites of Uranus and Neptune.
Asks for details of WL's system of speculum polishing and telescope construction as JH is preparing an article on telescopes for the Encyclopaedia Britannica.
