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 signed the certificate, and stated that FG is known to him.
Has received JH's letter from Gassiot and submitted it to the committee dealing with members of the Philosophical Club.
Would like some suggestions for books to be awarded for the Maths prize at Eton.
Comments on the reports of the birthday celebrations for JH's aunt Caroline.
Sending a series of magnetical and meteorological observations made at the observatory. Comments on these.
Are preparing an objective for JH, which they expect to send in August.
Wants JH to name the circle of uniform temperature of the ocean near the equator. Explains the circle of uniform temperature.
Asks to be allowed to join the new Philosophical Club on a trial basis [see letter of same date to John P. Gassiot].
On WH's 'Hodograph' and theorems of parabolic motion and the relation between velocities, initial velocities, and time. Praises WH's son. Cape Results nearly finished. Revising book on astronomy. Plans to 'attack' quaternions. Mentions parabolic functions and Benjamin Peirce's claim that the discovery of Neptune was accidental.
Announces next meeting of Philosophical Club.
Asks time and place of next meeting of Philosophical Club, having received invitation lacking that information.
Presents 'tables for facilitating the approximate prediction of occultation and eclipses for any particular place,' so that seamen without specialized backgrounds in mathematics can observe and improve hydrography.
Sends some new theorems concerning undisturbed parabolic motion; believes that much remains to be discovered in this field.
Sends some results concerning undisturbed parabolic motion. Laments the Irish famine.
Sends angular results from various astronomers using similar epoches.
Studies two possible orbits of Gamma Virginis; sends complete descriptions of both, including calculation of the apparent and actual ellipse. The first orbit combines the data of other astronomers.
Skeptical over plan for galvanic illumination of wires. Has not yet seen J. B. Biot article; states he has always held Biot in high regard. Discusses naming of new planet.
Is very grateful for his assistance and encloses the page of the report in which he publicly acknowledges this. Further results since the return of the great atmospheric wave of 1845.
Is reading JH's book and marvelling at the condensed amount of information it contains. Has been observing some of Wilhelm Struve's more difficult objects. Regarding the double star Antares. Has been testing his telescope for errors and found it accurate.
Will be pleased to accept his offer of the glass wedges. Bad weather has upset his observations. Gives some of his recent observations. James Challis doubts the existence of a ring round Neptune. Is not impressed by Capt. W. S. Jacob's observations.
