Has been unable to return the papers as he has been so busy. Proposes making working drawings as he suggests. Will take the papers to the Dover Railway to ensure their safety.
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.

Glad to hear that there is a possibility that JH will visit York. Another expected visitor will be T. Donkin, brother of Bryan Donkin.
Advises that JH has been elected President of the B.A.A.S. for its meeting at Cambridge in 1845; also some comments on the magnetic survey.
Encourages [B.A.A.S.] to accept offer in enclosed letter by W. S. Stratford, volunteering to assume duties of late Francis Baily in publishing star catalogs of N. L. Lacaille and J. J. L. Lalande.
Comments and questions about a 'cone of the second order' in mathematics.
Some comments and questions on mathematics.
Sends copy of ES's memorandum to George Peacock describing progress in publication of magnetic and meteorological observations. Encloses copies of observations from Antarctic survey and Ceylon. Reasons for H.E.I.C.'s hesitation to expand survey by C. M. Elliott. Praises C. J. B. Riddell's book, which described portable magnetic apparatus that is now requested by observers worldwide. Recent changes in other instruments. Reimbursement for instruments provided to observatory in Newfoundland. Recent results of surveys on Continent, in Canada, and by Capt. Blackwood in Torres Straits.
Forwarded to George Peacock JH's letter of 11 Sept. Karl Kreil will send self-registering instruments that ES ordered for Kew observatory. Influence of vapor pressure on barometer readings. Introduction of hygrometers.
George Peacock returned JH's papers, with letter by Peacock. ES forwards these to JH.

Sends JH a letter from Thomas Maclear, in line with Francis Beaufort's instructions.
Left prints of Francis Baily for JH, and will send a pamphlet about a long standing controversy in which RS was involved.
About trying to convert some surveys to a base using RS's standard yard.
Having difficulty drawing the Great Nebula in Orion using both JH's and [Francesco] De Vico's observations; prints of Francis Baily are almost ready.
Expands on GA's proposed letter writing scheme in place of holding a magnetic congress [see GA's 1844-7-30].
A note accompanying a draft of the report on magnetic observations to date at British stations, and a circular to be sent out.
Discusses publication of James Grahame's [History of the United States of North America] revised. Includes circular describing Grahame, his project and the cost of the books.
Magnetic phenomena move in opposite directions in the northern and southern hemispheres. This contradicts a report made by JH. Asks permission to omit JH's statements concerning this issue.
