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 election to the Astronomical Society and for the award of its gold medal. Sends a proof of a new chart of the moon by W. G. Lohrmann. Sends two papers of his own. Hopes to send notice of John Pond's comet orbit in 1825.
Finds no errors in JH's letter on the parallax of Mars. Sends his own calculations. Has not found the barometrical readings JH requested.
Berlin Academy plans a new Astronomical Chart. Thanks for JH's work on the double stars. Will see he has changed his address.
Asks questions about the prospectus [see JE's 1826-3-2] prepared by the Berlin Royal Academy for a map of the heavens. Asks JE to send JH a copy of [K. L.] Harding's star atlas.
Will send JH some barometric observations; describes the barometers with which the observations were made.
Reports on interest at the Astronomical Society, especially of [Thomas J.] Hussey, in the plan of the Berlin Academy for a new star chart. JH cannot participate due to JH's commitment to re-examine his father's nebulae, which requires that JH reside far from London.
Regrets he has taken so long to answer his letter. Gives reasons why the Commission does not allocate the same zone to two astronomers. Readings of J. Grooby and T. J. Hussey. Thanks for JH's work. J. E. Bode's work will be continued.
Pleased that JE will continue the Berlin Ephemeris. Makes various recommendations regarding it. Hopes that someone will reduce Thomas Brisbane's observations of southern heavens.
Sending the first volume of his Ephemerides for the Astronomical Society, also for Francis Baily and W. H. Smyth. Comments on various aspects of the Ephemerides. Thanks for JH's excellent work on Light.
Informs JE that the R.S.L. is awarding JE a Royal Medal for JE's work on Encke's Comet.
Is carrying out a study of double stars, comments on some readings, and would welcome any of JH's observations. Is planning to build up the library commenced by J. E. Bode at the Observatory. The chart of T. J. Hussey is being engraved.
Thanks for his letter, which had been forwarded to his old address. Is pleased he intends working on double stars, though 70 Ophiuchi may prove difficult. Will send some of his own readings for double stars. Like him, he is astonished at the acrimony of the attack on Thomas Young and the Nautical Almanac.
Has been informed that JH will be going to the Cape. Comments on JH's information on double stars, and on a passage in one of his memoirs. Regarding JH's Prelim Discourse. Work of Fearon Fallows and Thomas Henderson at the Cape.
Hopes JE will write to JH at Cape. Responds to JE's comments on JH's method of dealing with double stars. Thanks for generous comments on JH's Prelim. Discourse.
Sending his observations of the recent comet. JH's journey has aroused great interest in Germany. Taking over the Observatory and expecting a visit from F. W. Bessel. Wilhelm Struve has planned a new observatory for St. Petersburg. Has met astronomer Manuel Johnson from St. Helena. C. F. Gauss has produced a method of observing the magnetic needle.
Tried unsuccessfully to observe Encke's Comet; succeeded in observing Halley's Comet, which JH discusses. Mentions JH's graphical method of treating orbits of double stars, JH's plans to return to England, moon maps, and sunspots.
JH has been elected to the Prussian Academy of Science; comments on JE's astronomical observations.
Asks JE to express JH's gratitude to the Royal Academy of Berlin for electing JH a foreign member. Discusses JE's observations of divisions in the ring of Saturn, JH's sightings of Saturn's satellites, the British Antarctic expedition, and comets.
Asks if JE or the Academy of Sciences wish to participate in the British plan to make worldwide magnetic observations.
Comments extensively on the orbits of recent comets.
