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.
Is a candidate for the headship of Reading Grammar School and would be grateful if JH would give him a testimonial.
Is grateful for the testimonial JH has given him; it will be useful.
Comments on sunspot activity.
Is glad he is pleased with the work of Balfour Stewart and himself. Has applied to R.S.L. for a further grant to carry on the observations and computations for another year. Intends to finance the last year himself. Since the death of his brother he has returned to business.
Announcing the death of her husband Augustus.
Has been trying to collect letters of her husband as she intends writing a memoir on him [Memoir of Augustus De Morgan (London, 1882)]. Would be grateful if she could borrow any of his letters to JH.
Was just leaving home when her note arrived. If the letters have not been already dispatched send them in a few weeks' time.
Sending 35 letters, has 20 more that she will send later if she would like to see them. Wishes she had the photographs of insects. Thinks an appendix of all the riddles would be amusing.
Has received the packet of letters and has chosen 28 of them. Quite understands that some of the more personal ones should not be included in the memoir. Her strength does not seem equal to the task. Hopes to show the true events connected with University College. Budget of Paradoxes is ready for the press.
Has sent a work on the metric system in France, which includes JH's own valuable lecture.
Is grateful for his comments on his own paper on vision. Would he refer him to the work by Mr. Chopal on lens.
Relating his recent experiments in dioptrics. Encloses a model of his air-lens. Is grateful for the reference.
Directs RM and Charles Pritchard to examine late JH's manuscript on history of double stars, sent to Radcliffe Observatory.
Report on late JH's manuscript on General History of Double Stars, bequeathed to R.A.S.
Encloses copy of JH's letter to R.A.S. [see JH's 1864-6-29] that accompanied JH's submission of W. L. Newman's tables for determining radii of aplanatic lenses. Suspects that there was more than one volume of tables.
Turned JH's mineral specimen over to N. S. Maskelyne. Poor health of GW's wife.
Provides details of JH's health, which is very tenuous, but seems to be improving.
Writes of the gentle, peaceful nature of JH's death that morning in the presence of many of the family.
Sends prints of solar photographs taken last week at Kew, as requested by Warren de La Rue. Regrets that picture on 11 Feb. was unsatisfactory.
In Nov. 1864, R.A.S. council instructed secretary Charles Pritchard to write to JH regarding tables by late [W. L.] Newman of York, but JW finds no evidence that Pritchard complied. Cannot find Newman's tables. Pritchard may have taken them.
