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 grateful for his letter regarding the Portland vase; has shown it to Peel, who has agreed to introduce a short bill to protect such properties. Will read JH's letter to the Trustees.
Sends the Ticehurst Account books. Comments on the various funds. Regarding the local rates.
Sends the amended books. Regarding payment by the week or day. Hopes that the dispute with Mr. Morrell can be amicably settled.
Much obliged for JH calling but regrets he was out. The question [on steam] they have been discussing seems to be answered by a paper by a Prof. Karl Holtzmann he has just come across; comments on this. If JH is coming to S. J. A. Compton's (2nd Marquis of Northampton) soiree will he come and dine at St. James' Place?
Was not aware when he wrote his paper that doubt existed regarding the invariability of [the absolute heat of steam?]. Comments on the variations in the theories of S. D. Poisson and Karl Holtzmann. The experiments JH suggests would be highly interesting. Would he like to see Holtzmann's paper?
Has no doubt that any improvements JH suggests should be published. [John?] Taylor has borrowed Holtzmann's pamphlet, which will be sent as soon as returned. Karl Holtzmann's formula for air appears quite out. Gabriel Lamé evades the question. If JH writes anything on his calorimeter hopes he will mention the various questions raised.
Question of procedure about considering the magnetic observations for publication.
Thanks for JH's valuable information on actinometers. Encloses particulars that HB sent to [J. H.] Kay along with instruments.
Rejoices that JH plans to persuade H.E.I.C. to publish results of magnetic and meteorological observations. No one at R.S.L. has been in charge of these observations since Humphrey Lloyd gave it up. Submits JD's list of stations and observations. Encloses specimens of JD's pure 'anchovia' and 'Sabrina.'
Reviews establishment of H.E.I.C. observatories and comments on quality of magnetic and meteorological observations at Simla, Madras, and Singapore. Has heard nothing from A. B. Orlebar, director of Bombay observatory.
Observations from H.E.I.C. stations were supposed to be sent to foreign secretary of R.S.L. Prospects for persuading H.E.I.C. to reduce and publish these. Best methods of publication. Toronto volume should be available next week. Report by W. R. Birt was delayed.
How to obtain copies of H.E.I.C. observations. Humphrey Lloyd never intended to process data from H.E.I.C. observatories; these were added to survey after Lloyd's original (1838) offer to superintend B.A.A.S. observations. Sends copy of Toronto volume to JH to use as model for H.E.I.C. publications. Asks for JH's suggestions for Arctic observations next winter. Encloses note from [T. R.] Robinson in Parsonstown.
Lists 17 foreign and six English scientists to whom ES sent JH's letter and Toronto volume.
Is horrified at the wanton destruction of the Portland Vase in the [British] Museum. JH suggests flogging as appropriate for such acts of vandalism [see JH's 1845-3-18].
JH comments on JL's 'memoir on the heat of vapours,' indicating JH's dissatisfaction with the experimental basis (the experimental work of J. L. Gay-Lussac) for the conclusions. JH offers improvements in the construction and operation of the ice calorimeter.
Judges the unfinished portrait of Francis Baily a faithful rendering, although he is portrayed without the glasses, which he usually wore. Fears the intractability of [W. S.] Stratford and its implications for the workings of the R.A.S. Council. On the dispute between [W. R.] Dawes and [George] Bishop and how to resolve it.
Has received the missing manuscript and models from York, yesterday.
Sends the printed receipt for £1,000 being the amount of Francis Baily's legacy. Please sign and send it to his own bankers.
Introducing a Dr. Warwick, who has given lectures on the Elements of Chemical Science and who would like some authoritative advice on some astronomical matters.
Based on JH's 1821 formula in R.S.P.T., WN calculated aberrations of compound double achromatic object glasses, to be used in determining radii for grinding lenses. Explains theory. Attempting to construct 4.2-inch lens.
