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.
Received the enclosed silver plate on which is an impression made by the moon; has he any comments. Has been experimenting with solution of bichromate of potash and sulphate of copper exposed to actinic influence. Has been giving his attention to ferrotypes recently.
Has forwarded some of the late Professor Thomas Henderson's manuscripts to JH. An application may be made to the Government for a pension for the daughter. The books are to be sold and he will send a catalogue.
Wonders if JH could be persuaded to write a series of articles on meteorology for the Gardeners' Chronicle. If unable, could he suggest a suitable substitute?
Magnetic questions have been sent to foreign observers but not the British. Why?
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.
A copy of the question circular, signed by JH, sent to GA [see GA's 1844-12-17].
As secretary of Wernerian Club, CM requests information from JH on atmospheres of moon and planets.
Sent out copies of JH's remarks on Toronto actinometer. Expects that observations recommended by JH will be made next summer. Replacement for J. H. Kay's broken actinometer will arrive [in Tasmania] next June. Possible remedies to declination readings.
Mostly news of JH's family; JH inquires as to the state of health of JL's mother.
JH expresses some concern about the accuracy of a wet bulb thermometer, as he is not clear about the nature of the experimental base for its use.
Sends 30 copies of JH's letters by coach. Will charge to the B.A.A.S. account.
Requests information on behalf of the Magnetic and Meteorological Committee of the B.A.A.S. Desires AQ's assessment of past achievements by 1845-3-10. Lists works to be forwarded before end of year.
Requests papers relative to a preface to the catalogue of [N. L.] Lacaille's stars, so that the catalogue may be printed.
Requests that JH write a recommendation for C. P. Smyth's nomination to the position of Astronomer Royal for Scotland.
Is obliged for his list of James Dunlop. Has been reading JH's memoir of Francis Baily. Comments on this.
Sending the note for JH's son on how to decimalize fractions of a pound. JH's memoir has gone to press. Would like details of JH's work on the Southern stars for the Annual Report.
Still working on his Cape observations.
A note of acknowledgment for receipt of books, which JH has forwarded.
Requests AD's views on the benefits deriving from the worldwide system of magnetic and meteorological observatories. Various publications coming from these observations will be sent to AD.
