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.
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.
[Charles?] Pritchard has embittered the subject so he must just acknowledge the receipt of JH's 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.
Correction to R.A.S. report regarding eyepiece that RH invented for viewing sun, but which was attributed to JH by Charles Pritchard.
