Thanks for his letter. Has no copy of JH's Cape Observations so cannot refer to them. Comments on articles on telescopes by JH; they do not lead him to adopt the arrangement he adverted to 10 years ago. Regarding priorities in discoveries.

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.

[Charles?] Pritchard has embittered the subject so he must just acknowledge the receipt of JH's letter.
Cites quotation from Cape Results proving that JH invented the diagonal solar eyepiece. Discusses RH's claim. Note to JH accompanies this letter.
Gratitude for JH's gift to R.A.S. of William Herschel's manuscript series on observations of double stars. Encloses two pages of proofs for JH's approval.
Presents eight-volume copy of William Herschel's 'Sweep,' transcribed by late Caroline Herschel. Reviews her career.
Charles Pritchard was wrong in ascribing priority for diagonal reflecting telescope in Pritchard's address to R.A.S. As early as 1825, JH was first to use diagonal reflector. Describes its construction.
Did not insinuate that RH plagiarized JH's idea of 'diagonal reflector,' but feels justified in defending JH's claim to being first to apply it.
Correction to R.A.S. report regarding eyepiece that RH invented for viewing sun, but which was attributed to JH by Charles Pritchard.
