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.
Is publishing a work on rare atmospheric phenomena. Lists names of persons who have assisted with observations. Would like to inscribe the book to JH.
J. F. Daniell informs JL that the table was calculated by William Galbraith. James Apjohn states everyone is in agreement that the absolute heat of steam is constant, but JL disagrees. Intends raising the matter of John Southern's experiments at the next meeting of the B.A.A.S.
Obliged by JH's letter. Would he let him know what he thinks of raising the matter of repeating John Southern's experiments. His own eldest son has gone to Langley; he shows little aptitude for figures but a decided turn for Natural History.
Observed Comet Mauvais. Is grateful for JH's intervention on Observatory matters. Extra Meridian Instruments defective. Continues observations of variables. F. E. Wilmot's land survey cancelled. Magnetic survey progressing. Mary Maclear ailing.
JM is traveling in Germany for some time and intends to end up at a scientific conference in Bremen. He encourages JH to try to attend that conference so they may become acquainted.
About the financial arrangements for Caroline Herschel [see JH's 1844-1-2], and news of her health.
B.A.A.S. have been trying to arrange their 1846 meeting at Cambridge. William Whewell alone is opposed to this suggestion. Everyone agrees that JH should be the next president when the Dean of Ely retires. Can they have JH's views.
Regrets he made a mistake in his letter; he meant 1845, not 1846. William Whewell has been overruled and the B.A.A.S. are to meet at Cambridge in June 1845.
Rejoiced to receive his friendly letter, even though they have no hopes of seeing him in 1846. They are still on friendly terms with William Whewell, though they disagree on the Cambridge meeting.
Gives news of the death of JN's father.
Offering hospitality to JH should he attend the B.A.A.S. meeting at York. Has been studying the theory of the manufacture of achromatic telescopes. Comments on the quality of glass available. Swiss seems to be best, though expensive. Deplores the loss of Francis Baily.
Glad to hear that there is a possibility that JH will visit York. Another expected visitor will be T. Donkin, brother of Bryan Donkin.
At the request of Mr. Clift, acknowledges JH's communication of the case of the Mare with the intestinal calculi. The specimens are very acceptable.
Advises that JH has been elected President of the B.A.A.S. for its meeting at Cambridge in 1845; also some comments on the magnetic survey.
Comments and questions about a 'cone of the second order' in mathematics.
Some comments and questions on mathematics.
Not acquainted with proposal by A. T. Kupffer. Replies to queries by B.A.A.S. committee regarding continuation of magnetic and meteorological observatories. Expects self-registering instruments to supersede human observers soon.
Approves of proposal by A. T. Kupffer and Edward Sabine for international magnetic congress under JH's leadership. [Reply to JH's 1844-7-22 to HL.]
As secretary of Wernerian Club, CM requests information from JH on atmospheres of moon and planets.
Agrees to host congress at Cambridge to assess data from [magnetic and meteorological] observations. Suggests adding D. F. J. Arago to list. Will include this in GP's address to B.A.A.S at York. [JH annotation: List of five members.]
