Thanks for, praises, and comments on WH's 'Systems of Rays' paper. Says WH will have a distinguished career. Mentions other works and hopes to forward them with others he receives to WH.

Expresses regrets that George Airy's memoir on spherical aberration in telescope eyepieces and WH's 'Theory of Systems of Rays' reached JH too late for adequate treatment in JH's 'Light.'
Thanks for remainder of WH's essay on 'Systems of Rays.' Recalls error-ridden copy of JH's Light given to WH; sends correction. Wishes to propose WH for membership in Astronomical Society.
Acknowledges receipt of papers sent by WH for Astronomical Society and R.S.L. and will deliver them, but currently has not time to say more. Looks forward to enrollment of WH's name among members at next Astronomical Society meeting.
Was pleased to recently admit Capt. [Francis] Beaufort as WH's proxy in Astronomical Society.
Thanks WH for letter on [J. T.] Graves's paper [see WH's 1829-2-25]. Admits JH could be in error concerning Graves's doctrines, but will let mathematical world form its own opinion.
Regrets lack of time for WH's paper but has been occupied with nebulae and double stars. Finds it difficult to concentrate on one subject. Has proposed Edward Quin for Astronomical Society membership. Mentions [Francis] Beaufort's penchant for astronomy and the recent R.S.L. elections, as well as JH's wish to meet WH personally.
Thanks for sending extension of JH's theorem and expresses its significance. Will send copy of paper on differential and integral calculus. Includes results of calculations of orbits of double stars and mentions orbits of satellites.
Thanks for sending results about conical polarization and introductory lecture on astronomy communicated through Francis Beaufort. Had hoped to send WH JH's yet to be printed catalogue of double stars.
Gives incomplete report on observations of nebulae and double stars and theories on the Milky Way and Magellanic Clouds based thereupon. Thanks WH for his explanation of WH's new dynamical method, but JH admits that he understands only its 'general scope.'
Replies to WH's letter on 'Scotodynamics.' Cannot follow WH's analysis of velocities of vibrations and disturbances, but finds it symbolically beautiful and powerful. Notes that diploma [?] arrived and was sent to Hanover. Thanks WH on behalf of Caroline Herschel, who sent a letter acknowledging the honor bestowed on her by Royal Irish Academy.
Comments and expands on James MacCullagh's paper on laws of reflection and polarization in crystals.
In reply to WH's 1839-2-8 inquiry, JH believes that 'Skotodynamics' (the propagation of light waves) is a new line of research. Caroline Herschel is ecstatic about her Royal Irish Academy medal.
Requests another copy of WH's paper on light, recently read at Royal Irish Academy, having sent JH's own copy to Prague's [Karl] Kreil for description of [Humphrey] Lloyd's vertical magnetometer contained therein. Has WH yet found the three axes of the universe? Comments on WH's sister's 'charming' poetry.
Notice on the 'final laying up' of the Old Telescope, with a 'Requiem of the Forty-Foot Reflector,' sung by JH's family on New Year's Eve.
Requests autographed copy of WH's sister's poems, wanting to send them to an acquaintance who translated some of JH's work. Expresses a theory about cause and effect. Mentions minutes of Royal Irish Academy, a reform of the constellations, and WH's three axes of the universe.
On mode of conveyance of WH's sister's verses and the autographs for JH's acquaintance.
Has been delayed in congratulating WH on pension by a delightful visit from Maria Edgeworth. Praises highly verses sent by WH's sister to Lady Herschel.
Highly recommends a [William H.] Harvey (formerly Government Treasurer at the Cape) for the professorship of botany at Dublin.
Returns two papers, which had been missent, thus preventing JH from communicating them at a meeting.
