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.
Thanks for his letter about her theory regarding aerolites. Has another query on this question.
Note to accompany forwarding of a letter; remarks on T. R. Robinson's upcoming cataract surgery.
Has written to Kew Observatory to send on the photographs.
Is sending solar autographs. Notes that in groups of spots the larger precede the smaller spots. Can JH form any theories from this?
Detached postscript that discusses the margins of the two photographs, which seem to show that all planets are in the near hemisphere.
Would like him to accept the enclosed paper on the cause and effect of dew. Comments on various points.
The volumes of the Sinai photographs will be dispatched tomorrow. The cost of the survey has been covered by subscriptions and he will forward a statement of the account later.
Has no idea whether the sunspots appeared suddenly or gradually. The Kew people may be able to help in this matter. Comments on some more sunspots.
Sends two of his publications, one on terrestrial magnetism at Berlin. Comments on the results, and wonders if JH would enlist the help of the B.A.A.S. to finance further studies by H. J. R. Petersen.
Sends map from his new atlas. Reports finding a region rich in bright stars in the northern hemisphere but distinct from the Milky Way. States that in a Royal Institution lecture, he will claim that telescopes cannot reach the limits of the sidereal system and that it is far more complex than traditionally assumed.
Has just learnt that some negatives were sent to his former place of residence. Will forward them when he goes to the City. A vote has been made from the Donation Fund of the R.S.L. for six copies of the Kew Solar negatives.
Will endeavor to obtain information on the Dock shares. Maria (HH's wife and JH's daughter) and infant are doing well.
Is grateful for his note. Would like to be certain of W. C. Wells's theory before he revises his opinion. His original paper was much larger. Gives some examples where he thinks Wells is in error.
Cannot afford fees he must pay to be ordained. Asks for financial assistance. Includes letters from a tutor and a professor.
Sends report of Edward Sabine's 'conversaziones' of 12 Mar. and 23 Apr. Mrs. Birtwhistle wrote from Peking on 2 Feb.
Forwards letter from G. A. Erman to JH and two papers by Erman. AM wants to visit JH to learn of prospects for Erman before AM leaves soon for zoological and magnetic observations in Malay Archipelago.
Thanks JH for mention of him in Outlines Astr. Sends detailed observations of Alpha Centauri system.
Describes difficulties in producing glass pen and attaching it to pendulum to produce precise curves for aligning equatorial [telescope mount]. Sent artistic sample to JH's wife.
Acknowledges receipt of letter and papers from G. A. Erman.
Desires permission to present JH's 'diagram of "macularity"' to the R.A.S.
