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.
JH's exertions and friendship are a treasure. Will visit them on Monday next.
Has begged Edward Ryan to see JH and have a consultation about some of RJ's affairs, which he would like to settle. Pleased to hear that Willy [Herschel] is doing so well.
Wished Edward Ryan to consult JH regarding [G. H. Gordon (4th Earl of Aberdeen)]. as he knows him better. Will not make any move until he has consulted Sir James Graham. Unable to manage Monday, but any day after will suit him. Mrs. Jones is very depressed and needs a change of air.
Sending diagrams of Halley's Comet traced from a work, The Orbs of Heaven.
His letter and accompanying packet arrived for which accept his best thanks for the valuable contribution to the literature of physical geography. Is gratified by JH's commendation of his own Physical Atlas.
Thinks it may be a good idea to utilize aluminium to coat the speculum of reflecting telescopes. Is shortly to take command of iron works and furnaces and hopes to carry out experiments to produce barytic glass.
Has received news of a cargo of cryolite from Greenland. Outlines the various possibilities of using it for the manufacture of chemicals and glass. Sends his method of manufacturing aluminium.
Has no objection to his letter being communicated to the R.A.S. Comments on his observations. Thanks for his paper on musical pitch. Sees that new copper coinage is to be introduced and hopes that JH will use his influence to introduce the decimal system.
Royal Society of Edinburgh would like JH to referee a paper on the mean temperature of the earth by J. D. Forbes. Would JH be willing? Sends a little biography of the late Professor Thomas Henderson, who is now nearly forgotten in his native city.
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.
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.
