Would like to reprint JH's paper 'On the Projection of the Sphere' in their Educational Times. Can he supply a reduced diagram?
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.

Points out error in his own book and enlarges on that point.
James Challis has informed him that J. C. Adams is to be the new Observer at Cambridge. Does not see how he himself can ever obtain the post. Seems likely that he may give up the profession.
Thanks for the case of wine. Saw Alexander Herschel this morning and is getting some information from him. Has been on board the Warrior.
Thanks JH for a memoir on the projection of a sphere. Expresses the wish that map-making, so neglected, be taken up thoroughly.
About a request of JH for some palladium from the R.S.L.
Tells JH that he can be ready to see him at any time.
Forgot to reply to his letter as he locked it away. Regarding the supply of oxygen. Does not think it applicable in the case of a confinement.
Many thanks for his new projection of the sphere. J. L. Lagrange has two papers of 1779 on the subject. John Lee elected president at the R.A.S. He himself has resigned from the council.
Encloses pamphlet on atmospheric electricity by Joseph Henry and two pages about 'Carpet experiments' in New York by Joseph Lovering. U.S. going through 'sad political trial.' Does astronomy offer examples of severed systems or broken planets being re-united?
Discusses 'autograph of the sun' he sent earlier. Discusses measuring relative temperature of sun. Has an unpublished letter of Galileo to Cardinal Barberini regarding sunspots.
Note to accompany sending of palladium [see GS's 1861-3-14].
Appeals for JH's support of the Life Boat Institution.
Thanks for the palladium [see GS's 1861-3-22].
Claims to have demonstrated that light intensity increases as distance from light source increases. Applies this to inner planets, where sun should appear dimmer than on Earth. [JH annotation: 'Frivolous & Vexatious.']
Reminds JH that the algebraic formulation of the theory of the achromatic telescope eyepiece was formulated by GA.
Is sending a tract on 'Probable Errors.' Further observations on JH's article on telescopes.
Expresses thanks for sending Smithsonian Contribution to Knowledge, a report by A. D. Bache, and materials from the American Philosophical Society.
The Churchwardens of Hawkhurst are inviting JH to the Easter dinner.
Recognizes the validity of GA's claim to the eyepiece theory [see GA's 1861-3-27]; JH did not have space to deal adequately with the subject of telescopes.
