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.

Came to Florence on account of the sudden death of Mrs. [Joanna B.] Horner. Thanks for the translation of a book of the Iliad, but thinks only Greek scholars should read it. Has some queries regarding the migration of hippopotomi; can JH supply any facts or references?
Has been requested by Edward Twisleton of the Public Schools Commission to give evidence in favor of introducing the teaching of the elements of science in schools. Would like to know JH's opinion, and also if he is willing to give evidence.
Introducing his eldest son and his son's newly married wife.
Sending a lump of a substance quarried near Edenderry; has found some very similar in a quarry of his own. Can send some more specimens. Congratulations on his Baronetcy. Has been prostrated with bronchitis.
Origin of siliceous minerals sent by JH. Planning tenth edition of Principles of Geology. Convinced that changes in position of land and sea were principal causes of climate changes. Questions [James] Croll's theory of astronomical influences on climate, based on data from U. J. J. Le Verrier. Compares earth-pillars in Rhone valley with those in Tyrol. Wants tenth edition to include woodcut of JH's [1821?] drawings of earth-pillars.
Regarding the editions in which he cited JH's paper. Further comments on James Croll's paper, and on the effects of glacial and astronomical events. Is the quantity of heat radiated by the sun in the course of the year always the same? Thanks for the drawings of the Botzen columns.
Has ordered that a copy of his new 6th edition of the Elements [of Geology] should be sent to JH. He wants the drawings of the earth pillars for the 10th edition of his Principles dealing with the effect of rain. JH's drawing made a great impression on him.
Impressed by JH's [1824] drawings of earth-pillars in Botzen. Plans to visit them this year. Causes of earth-pillars. Speculates on climate changes on planet Mars.
Took JH's box of specimens and had a discussion with William Logan, A. C. Ramsay, and some young surveyors, one of whom had examined JH's neighborhood. Similar rhomboids to the Irish ones have been located in Wales. Hopes to have a discussion on this subject later. Can JH give, or refer him to data, the temperature of celestial space without the sun? Returns the drawings with many thanks.
Discussion on JH's geological specimens took place at the Geological Society on Wednesday. Gives some of the points raised at the meeting. Regarding the length of time that separates the extremes of eccentricity of the earth's orbit. Has raised the matter with G. B. Airy.
Has just received the accompanying letter from James Croll so that JH can save himself the trouble of answering CL's query.
Sending the results of his comparison of JH's drawing and the actual earth pillars of Ritten and Stalden.
Hopes to send a copy of his new edition [of Principles of Geology] in a few weeks. Hopes he will be satisfied with the manner in which he used JH's drawings. Comments about variations in the obliquity of the ecliptic. Quotes correspondence he has had with E. J. Stone of Greenwich Observatory. Would like JH's opinion on the matter.
Did not intend to trouble him with his proofs, but as he has cited JH in the chapter dealing with the astronomical effect on climate he sends proofs for this chapter. Would like to quote JH's two letters on the subject. The whole book is set up and hopes to send the volume in November.
Much obliged for calling his attention to M. C. E. Du Four's paper, though he cannot reconcile the general reasoning. Comments on the effect of the Sirocco on the Föhn of the Alps.
Sends Captain [P. F.] Shortland's account of his recent soundings and temperatures of the sea. Comments on these readings in the light of theory. What does JH think of the matter.
Was pleased to get his twelve pages of slips returned this morning. In one he proposes an alteration of 3% instead of 1003 to 1000. Which is correct?
Comments on the relationship between the plane of the earth's orbit and the obliquity of the ecliptic.
Received some proof sheets this morning of the Appendix to CL's book on the Antiquity of Man. Has read through the book with great interest. Comments on various points. Will have to revise their ideas on the length of human existence. Has had another letter from Twisleton so supposes he must try and write on science in schools. Have had sickness for the first three months of the year.
