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, 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.
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.
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.
Expresses views on nature of exponential functions and defines terms that may have caused confusion in [J. T.] Graves's paper, which JH found unsatisfactory. Requests JH's reply.
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.
Was pleased to recently admit Capt. [Francis] Beaufort as WH's proxy in Astronomical Society.
Thrilled by JH's encouragement concerning WH's 'Theory of Systems of Rays.' Enthusiastic about his career prospects at the University of Dublin.
Sorry that he could not meet JH when JH was in Dublin; hopes to be introduced to JH soon. Answers JH's queries about WH's work; explains that he is studying 'the general properties of systems of rays, and of the surfaces with which they are connected.'
