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.
Compares in detail observations of several double stars made by several astronomers, and comments on differences; JH also describes a sighting of Biela's comet.
Was pleased to receive the elements of Gamma Virginis. Congratulations on his knighthood. J. J. Lister called on him recently and would like to see JH.
The time he proposes to visit them is very suitable and J. J. Lister will be there. The substance found in JH's telescope is very interesting. Hopes his mother is still well.
Has received the chronometer and will return it to Lister, together with his remarks on apertures. Charles May has found another individual suffering from color blindness. A friend has successfully made a reflecting microscope.
Sends items by F. W. Bessel and G. A. Plana. Will be dispatching boxes to various European towns next week and will be pleased to include any items from JH. His observations made recently show interesting results. Comments on these results and the influence of the bore.
Queries regarding a corroded clock face, and description of harvest bugs. Has an intermittent river in their district. Has now set up the Munich telescope and would be pleased to show it to JH. Does he want Amici's mirrors?
The black broth that the Spartans liked must have been mushroom ketchup. Suggests way of obtaining a portable dome. Sends drawing and description of the harvest bug. Is pleased to hear of his projected Cape expedition. Is carrying out observations of the moon.
Came with the intention of paying JH money, but finds he is out; what shall he do? Can he also advise him about the map for the R.A.S.?
Considers his letter a particular favor [possibly giving the news of the death of JH's mother]. May be able to meet Lady Herschel in the Spring.
His wife is ill and is now at Brighton. Has just received JH's parcel. Is pleased JH likes William Whewell's article. Adam Sedgwick has refused a living.
Is gratified that JH has consented to sit for his portrait. Let him know the artist he has selected and they can arrange sittings.
Entirely approves of his choice of Thomas Phillips for his portrait. Has already painted Hugh Percy (3rd Duke of Northumberland).
Has probably already received a letter from the Lord Provost inviting JH to become a candidate for the chair of Natural Philosophy at Edinburgh. Outlines the duties. Hopes he will also accept the presidency of the Royal Society of Edinburgh.
Has been prevented from answering his letter earlier by increased illness. If he returns to town he will have pleasure in meeting H. C. Schumacher. Believes the pound must be made of bell metal. Thought JH was on his way to the Cape, but sees his letter was written from Slough.
Obliged for the present of his papers. Will keep them until the catalogue arrives. The improvements in his 20' telescope are interesting; comments on this. Will obtain the troy pound as soon as Parliament meets.
Wonders how JH's projected volume on Astronomy is progressing. Would also like a short biography of Francis Bacon.
Sends two articles for the R.A.S. Gained much pleasure from reading JH's Prelim. Discourse. If JH has written any other books for Lardner's Cabinet Cyclopaedia, he would be glad to receive copies. Work on Light has made great impression. Has Charles Babbage finished his Logs. yet? Cholera prevalent in Vienna.
Sending check in payment of JH's article on Celestial Mechanism in the Quarterly Review. Would be pleased if JH would now write an article on comets.
Has been induced to become a candidate to represent the University of Cambridge in Parliament and encloses his address. Would like JH's support.
Returns manuscript and corrected proofs of one of JH's papers on double stars, with the rest of the paper going to Francis Baily.
