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.
Writes to introduce JH's son William James and his new bride to the Lyell's. Both JH and his wife, Margaret, are suffering from illness.
Comments on the revolution of the apsides of the earth's orbit and its effect on glacier theory; further comments on the earth pyramids of Botzen [see CL's 1865-1-31], and associated phenomena.
Writes to CL about JH's response to James Croll's paper. Includes an extract from JH's letter to James Croll [see JH's 1865-2-6].
Does not gainsay the influence of distribution of land and sea on the climate. The change of eccentricity is also a powerful influence. Comments on this. Sees that CL's book is published. Is it too late to send his drawings of the earth pyramids?
Thanks for his Elements [of Geology]. Evidence from the Arctic shells is decisive. Sends drawings by book post. Comments on these drawings. Near Arezzo are similar phenomena in a soft sandy limestone. Measured the tallest column at Riten and found it 74' 10" from stone cap to base.
Some comments on the variation of the eccentricity of the earth's orbit, and the geography of Mars.
Comments on why JH gave 239 degrees F as the temperature of space. Geological specimens may be given to the Geological Society or to the Jermyn Street Museum.
Comments on a table of U. J. J. Leverrier on the eccentricities of the earth's orbit.
Further comments on the theory of glacier formation, urging causes beyond merely astronomical ones.
Describes exactly the route JH took to get to the point where he made his drawings of the earth pyramids at Botzen.
Comments on some of CL's writings; further argues that a canal at Suez and/or Darien would have a major effect on European climate due to the effect of ocean currents coming through such canals.
Some minor suggestions regarding CL's proofs [see CL's 1866-10-19].
Appreciates the receipt of volume one of the tenth edition of CL's Principles of Geology.
Sends a paper, which may help to clarify the effect of the Sahara Desert on certain European winds.
On the temperatures of water in the oceans, and the freezing temperature of sea water.
