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.
Encourages JH to visit at Nantes.
Is greatly obliged for the present of flowers. Has introduced another Herschellia into the world as he has used the name for a Disa.
Please accept her heartfelt thanks for his kindness.
Has had orders from the Treasury for full remission of duty on their astronomical instruments. Observatory will be founded early in March. Gives list of instruments added or to be added, in case JH's opinion is asked.
Is grateful for the gift to her son and for JH's time devoted to her son for his edification. Sir Gore hopes to call on the Herschels on the first fine day.
Will give a paper on fixing the image formed by the camera obscura to R.S.L. and wants to review it with JH first.
JH is indisposed, so WT will come to Slough to review paper [see WT's 1839-1-25]. Asks JH about appropriate curve on lenses for camera obscura for 2-foot focus.
Has received urgent request from Athenaeum to allow them to publish paper on 'Photogenic Drawing' before it is read to R.S.L. in light of announcement of the 'Parisian invention.'
Sent wrong paper to JH in Nov. 1838. Now sends complete meteorological journal from Mr. Lees, HD's stepson. [JH annotation: Answered 18 Jan. 1839.]
Cabinet found R.S.L. recommendations unsatisfactory. Merchants are urging the value of good geographical and magnetic charts of southern ocean. Geographical Society is preparing a document. Wolverly Attwood, M.P., questioning ministers in Parliament on this matter.
Forwards a request from C. F. Gauss for magnetic observations made in England.
Recounts a letter from William Rowan Hamilton, President of the Royal Irish Academy, commending CH on her service to astronomy.
Any news of Field Measuring bars—alteration in size of Observatory at Cape Town? Observations on use of magnetic needle. Has JH found a suitable country house yet?
Will bring CB's 'Engine' to Slough tomorrow, together with Dionysius Lardner's apparatus, which CB has 'taught to write.'
Has mentioned to Dr. T. R. Robinson their hopes of supplying the Cape Observatory with an equatorial telescope and theodolite. Encloses Robinson's comments. George Dollond would take two years to mount such a telescope. Curious paper in the Comptes rendus.
At the recent council meeting of the R.A.S., JH was nominated as president. Is returning the letters of F. W. Bessel.
Regrets that he cannot change the mind of the council of the R.A.S. over its nomination of JH as president.
Offering her services while JH is in Paris.
Recalls hospitality at Slough during EW's Eton days. Sets date to visit JH.
EW and wife plan trip to Eton soon to see sons. Hope to visit Herschels in Slough then. Despairs of Africa venture. Received details from JH's agent at the Cape of Good Hope.
