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.
Recommends a method for destroying wasps' nests. Refers him to the Gardener's Chronicle for information on flowering Cape bulbs. Has no idea where he can obtain deodar seeds. Would like to see his paper on the influence of light on vegetable colors.
Sending a paper in which he recommends JH's Prelim. Discourse; it is addressed chiefly to mechanics.
Received his letter just as he was about to lecture. Regarding the Institution, there are five or six telescopes in use and G. B. Airy is to deliver lectures, so JH's work may be useful.
Well-wishers of the Ipswich Museum hope to raise a fund for a lithograph portrait of G. Ransome; wonders if JH is interested in becoming a subscriber. Richard Owen is to deliver a lecture at the anniversary meeting next month.
Drawing attention to his prediction of the storms of 1838 and 1839.
Sends a copy of an ephemeris of Biela's comet for November and December.
Has just completed the orbit for the binary star Mu2 Bootis. Sends details. Could not send his notice of Biela's comet to W. R. Dawes as he did not know his address.
Is grateful for details of his method of calculating the orbits of double stars. Comments on some of his observations.
Will apply JH's principle at the first opportunity. Has made some successful observations of the star Epsilon Arietes. Intends observing Castor on every fine evening.
Communicating the elements of Castor and Corona by JH's method. Comments on these readings.
Sending him the elements of the new planet Astrea. Orbit is based on the Berlin observations. Differs from those given by J. F. Encke.
Regarding the strange appearance of the comet of Biela. Will observe the double star as soon as he has an opportunity.
Is obliged for his notice of the separation of Biela's comet; has sent extracts to H. C. Schumacher. Sends some observations made that evening. [Francesco] de Vico announces a new comet; so far he has been unable to trace it.
Has not been able to secure any angles of Gamma Virginis due to poor weather. Perplexed over the difference between J. H. Mädler and W. R. Dawes. George Bishop will be pleased to send any measures he may require.
Sends his observations of y Cygni. Comments on the differences in the readings of various observers. Still unable to observe the double star JH requested, but the weather has been poor.
Obtained first rate measures of the double star on 31 May, but since then the atmosphere has been hazy and so unable to send any further measures. Thinks it worthwhile to observe all the stars in Cassiopeia and Ophiuchus.
Elements of the new comet observed at Regent's Park.
In case he has not received a letter from Berlin he sends details of the planet of U. J. J. Leverrier.
Discovered a telescopic comet in Cepheus. Gives readings.
Has discovered another member of the group of planets between Mars and Jupiter. Gives readings. May be the lost planet of Niccolo Cacciatore.
