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.
Must report progress of meteorological reductions to B.A.A.S. Send specimen of 'Curves' before first week in September. Gives latitudes and longitudes for North American stations.
[WB's] sheets [of barometer observations] are well done. Sends European latitudes and longitudes. Will send 'Engraved Squares' soon. Notes errors in observations.
Explains 'discordances' as contraction of damp paper. Use 'Engraved Squares' to avoid this error. Possible error in barometer observations from Montreal. Diurnal 'undulation' appearing in data. American observations arrived, may fill 'missing intervals.' Keep record of expenses incurred. Postscript on color variation in stars.
Received WB's packet. Will send sheets tomorrow. Needs all 'Curves and data' before end of March for final report to B.A.A.S. JH's nerves 'shattered with night work.'
Received WB's atmospheric curves yesterday, but too late to report them [at 1842 B.A.A.S. meeting]. Final report will be presented at next [1843] meeting.
Must complete graphs of barometer curves before B.A.A.S. meeting. Did JH mistakenly include 1837 Bogota Almanac in barometer observations?
Sends two dozen more papers on barometer graphs. Must have all papers on subject by January. Pleased with WB's lunar observations.
Reduction of barometer curves is nearly complete. Must have all papers within two weeks to prepare for B.A.A.S. meeting.
WB's packet arrived safely today.
Received copies of barometer observations. Searching for original data (lists stations) that JH sent to WB. Invites additions to JH's report. Please send account of expenses.
Has check for WB's expenses.
Sends check. Asks for latitude and longitude of four American observation stations.
Delighted by Prince Albert's benefaction to [WB]. Curious results by [Robert Hunt] may lead to 'chemical discoveries of a new order.' Gratified by attention given JH's testimonial for Hunt.
Parcel arrived safely. Will examine it with interest.
WB's wave models show that barometer observations will reveal atmospheric dynamics like astronomical observations revealed planetary orbits. Encourages WB to seek simple method of temperature corrections applicable to all barometers. Offers possible mechanism. Send results to B.A.A.S quickly. Will send WB's letter to [Magnetical and Meteorological] Committee.
Omitted important detail yesterday in JH's description of self-compensating barometer. Columns must be variable, not constant.
Sent WB's paper and models to [B.A.A.S. meeting in] York, to be included in report of [Magnetical and] Meteorological Committee.
B.A.A.S. meets 18 June at Cambridge. Send contributions to report of Magnetical and Meteorological Committee to JH by 13 June.
Forwarded WB's report to B.A.A.S. at Cambridge. Sends payment for expenses. Two German meteorologists will be at B.A.A.S. meeting.
Perhaps periodic surges in atmospheric waves noticed by WB will repeat. Speaks of 'new climate' for globe. Hopes WB can attend [B.A.A.S.] meeting at Southampton.
