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.
Thanks for 'valuable addition' to HU's book.
Notifying him of a forthcoming meeting of the Lunar Committee of the B.A.A.S. Hopes he will attend.
Comments on the revolution of the apsides of the earth's orbit and its effect on glacier theory; further comments on the earth pyramids of Botzen [see CL's 1865-1-31], and associated phenomena.
Having read JH's paper in Good Words on the weather he commenced a series of observations of the state of the sky during three days of each lunation. Will be pleased to continue sending his observations if JH is willing to accept them.
Sending his paper on the causes of change of climate, and would be glad of JH's comments and opinion on its worth.
PS's results on light and magnitude of stars agree with JH's results at the Cape. Comments on PS's research on light of planets.
Draws JH's attention to an article in the most recent Philosophical Magazine.
In response to comments in a paper by JC, JH writes to establish his priority with respect to the significance of the revolution of the apsides of the earth's orbit and the eccentricity of the earth's orbit in affecting temperatures on the earth. JH had spelled this out in an 1830 paper for the Transactions of the Geological Society, and repeated it in his Outlines Astr.
Writes to CL about JH's response to James Croll's paper. Includes an extract from JH's letter to James Croll [see JH's 1865-2-6].
Sends copy of JT's '3rd Memoir,' along with specimens of liquid mercury ethyl and mercury methyl from discoverers Edward Frankland and B. F. Duppa.
Asks WW to check the R.S.L. council book for 23 Nov. 1826 to inform JH as to who was present.
Was pleased to receive JH's letter requesting him to communicate the subject to the Society. Has been busy preparing the Annual Report so has not had time to follow up Mr. Traye's papers.
R.S.L. approves of CP's optical work, believing it will be helpful at observatories abroad. CP comments on Alexander Herschel's prism experiments.
Regarding the editions in which he cited JH's paper. Further comments on James Croll's paper, and on the effects of glacial and astronomical events. Is the quantity of heat radiated by the sun in the course of the year always the same? Thanks for the drawings of the Botzen columns.
On the significance of the full moon and its influence on the weather.
At JH's request, WW sends JH a list of members present at the 'irregular' council meeting on 23 Nov. 1826, together with the business recorded in the minutes, which does not include any mention of the matter of the secretaryship of the R.S.L.
Attempts further clarification of the matter discussed in JH's 1864-12-20 to the P.M. Reiterates JH's recollection of a conversation between W. H. Wollaston and Humphry Davy, which JH had described in a letter [see JH's 1826-11-25 to Francis Baily] and which JH refers to in his letter of resignation to Davies Gilbert [see JH's 1827-6-27], which latter letter JH quotes.
Thanks for his letter concerning his own paper on the changes in climate. Points out parts where JH seems to have been mistaken in his views as expressed.
Does not gainsay the influence of distribution of land and sea on the climate. The change of eccentricity is also a powerful influence. Comments on this. Sees that CL's book is published. Is it too late to send his drawings of the earth pyramids?
By all means retain the specimens and send them to Lyell or anyone else as he sees fit.
