Lacks information on Augustin Fresnel. Praises JH's drawing as rendering unnecessary annexing one to his paper. Has not yet unpacked the new telescope sent by John Ramage.
Thanks JH for proposing WR for R.S.L. Discusses construction of air pump. Trying to simplify construction of vacuum. Will be in London in March.
Requests JH make any necessary corrections in WR's paper on 'Diff[erential] Thermometer.' Thanks JH for his efforts on behalf of WR.
Heard JH declined mathematics professorship at London University. WR is a candidate for the position. Asks for JH's support.
Cannot at present accept the situation [at University of Virginia] discussed in JH's letter. Is still a candidate for position at London University [see WR's 1827-7-28]. Thanks JH for honor bestowed.
Left his job because of precarious health. Is retired. Discusses achromatic telescopes and his ideas for correcting spherical and chromatic aberrations.
Sends [F. G. W.] Struve's observations on William Herschel's double stars because of JH's expressed interest in the work.
Announces eight copies of his Catalogus novus stellarum duplicium et multiplicium are being sent. Has delegated some work on double stars to his aid [E. W.] Preuß.
Surprised and grateful for JH's encouragement concerning his Stellarum duplicium. Informs JH that the observatory survived the fire at Abo. The university is moving to Helsingfors, Finland. [F. W. A.] Argelander will remain and is working on determining delineations of the foundation stars.
Asks where AQ can procure best instruments in England. Desires to view the interiors of English observatories. Wishes to have [Alexis] Bouvard, who is in need of a change of scene after [P. S.] Laplace's death, accompany him. Sees translations of English scientific works, especially JH's, as a desirable project.
Has missed seeing JH, who must be in the countryside with [Charles] Babbage. Hopes to see JH and ask advice for observatory at Brussels.
Thanks JH for letter. Regrets having missed possibility of seeing JH while in England. Asks JH to convince [Charles] Babbage to pass through Brussels instead of Rotterdam.
Discusses the poor health of Heinrich Olbers, and Johann Encke's inability to acquire the necessary instruments. Wants JH to send to CH a few of her 'Indexes.'
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.'
Feels distant from her family in England. Notes that the French occupation has changed Hanover from what it was when CH left in 1772.
Discussing William Herschel's financial difficulties, CH confides that 'she never felt satisfied with the support your father received toward his undertakings, and far less with the ungracious manner in which it was granted.' Regrets WH was not able to do more work with the 40-ft. reflecting telescope.
Writing her memoirs, CH sends for JH's perusal an account of her youth.
She 'can only think of what is past, and is for ever forgetting the present.'
Thanks JH for sending his second catalog of double stars; remarks that 'by the manner in which you gentlemen now attack the starry heavens, it seems that there will soon remain nothing to be discovered.'
