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.

Expected another letter from JH. Awaits this letter before leaving Portsmouth.
The belladonna JH gave him is throwing up vigorous leaves. Has a scheme for making it leaf and flower in the same season. Has some ingenious machines to show JH when he calls, which may be useful to JH.
Whewell and RJ plan to visit South Wales and would like to stop at Slough en route.
Relating the events of the last three years. Charles Babbage has published his Bridgewater treatise. Charles Lyell is just off to Norway. Mr. D'Arblay dies of a fever. Hopes JH is not working too hard. Very pleasant garden at Haileybury.
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 had no communication with Thomas Phillips regarding JH's portrait and they would approve of JH's choice of H. W. Pickersgill. Will call on Pickersgill when he is in town and arrange size of the portrait.
Has been laid up with influenza, which delayed his answer. Has seen H. W. Pickersgill, who will be very pleased to paint JH's portrait. Can he arrange a meeting?
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.
Will be leaving London on 16 July and would like to meet JH at some convenient time to carry out H. C. Oersted's commission.
Would like to visit JH at Slough and bring him some communications from J. J. Littrow at Vienna Observatory, where he has been recently visiting.
Has been confined to bed with pleurisy. Davies Gilbert called yesterday and gave startling news of the wonders of James South's new telescope. Can JH inform him of its true capabilities? Gilbert talks of having an object glass of 2" diameter made of Michael Faraday's glass.
Has never seen the fair copy of William Herschel's polishing book. Will be pleased to assist Wilhelm Struve regarding the Standards. Will ask George Everest to call on him and discuss the Indian operations. How did Herschel perfect the adjustment of his object glass? Has been experimenting with the Josef Fraunhofer spots.
Does he want a scale ordered form George Dollond for Wilhelm Struve? Will not be in London when Struve arrives. Has written a paper on the Standards for the R.S.L. and will send JH a copy when printed. Comments on the comparison of Standards.
Sends details of the measurement of Wilhelm Struve's standard. Is pleased that JH has given an invitation to [E. de?] Beaumont, who is anxious to become an astronomer and is about to spend £1,200 on instruments. Wishes that JH appeared in town more often.
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.
Capt. Kater is too unwell to write, but he would like to know whether JH is likely to claim the Navy Bills for his term as Commissioner of Longitude, as Kater will do whatever JH does in this matter.
She understands Davies Gilbert's report was from James South. JH's description of the telescope meets Kater's ideas. Kater has been much struck by William Parsons' (3rd Earl of Rosse) experiments on the formation of large mirrors. Wishes JH had called him when he was in town.
