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.
Has just been showing Michael Faraday some of his experiments on the influence of magnetism of bodies slowly precipitating; comments on this and will be pleased to carry out any experiments for JH.
Has been pursuing his magnetic experiments with crystals and will be publishing a memoir on them. Comments on these experiment. Is there a difference in the mass of the earth at the poles?
Is giving a series of lectures at the Collegiate Institution. Has made some interesting discoveries recently and has deposited a paper with Faraday for communication to the R.S.L. Comes to the conclusion that chemical action can be suspended by magnetic force. Comments on this.
Has often thought of the inactive condition of iron and has made some notes before he received JH's comments. Has overcome all JH's objections to the intrinsic difference in the two poles. Comments on some of these experiments.
Is desirous of procuring impressions of prismatic spectra from all parts of the globe. These should show the chemical influence of the solar rays. The B.A.A.S. may be able to help or Colonel Edward Sabine. Can JH use his influence?
Has been working for a long time on the supposed influence of magnetism on chemical action. Outlines an experiment he has used to show whether magnetism affects chemical action; would like his comments.
Encloses a copy of his own paper from the P.M. Has not found time to do the experiments suggested by JH, but hopes to shortly. Is revising some papers on the physical powers of the universe for re-publication.
Is grateful for JH's request to add his name as a subscriber to his book. Sends a volume entitled the Poetry of Science for JH's acceptance.
Is pleased he approves of his style. Regarding the experiments on the germination of seeds. His own son is progressing satisfactorily.
Is thinking of withdrawing his son from Christ's Hospital owing to his frequent epileptic fits. Should he inform the Prince Consort? Outlines his recent photographic work.
Since writing to JH he has taken medical advice and decided to leave his son at Christ's Hospital for the time being. Gave a lecture at the Royal Institution on Friday evening.
Regarding tides in the atmosphere. Suggests a possible way of measuring these tides. Has never seen the subject mentioned.
Sends a copy of the Britannic Censor. Outlines his aims in producing this new periodical.
Her brother has sent JH's letter and she will be only too pleased to send her poems for whatever purpose he requires them.
Has just received the news that Hartnell's son has passed the exams at Trinity College, Cambridge.
Enjoying the beautiful scenery, but the weather has not been good. Many thanks for the beautiful translation of Frederick Schiller. Has he added anything to his photographic discoveries? Saw some calographic pictures at Charles Wheatstone's, which improved on the Daguerreotype.
Would like some suggestions for books to be awarded for the Maths prize at Eton.
Sends JH a mathematical theorem.
On the deviation from the perpendicular of falling bodies.
Sending a copy of the English Universities. Has quoted JH in the third volume. Hopes that university reform will be a popular topic.
