As G. B. Airy has chosen not to stand as a candidate for the astronomical position in Dublin [Astronomer Royal of Ireland], JH is strongly supporting DL for that position.

On the questions of the usefulness of occultations and the use of mean time in astronomy, JH would much value WS's opinions.

Informs FB that it is JH's intention to resign as secretary of the R.S.L. at the next anniversary meeting.

Asks that list of errata be published before a committee meets to investigate 'the subject of Mr. Lee's [?] animadversions.'

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.

Communicates to WS the award of the Royal Gold Medal for his 'magnificent work on the New Catalogue of 3112 Double Stars.' Informs WS that award is for research completed within 5 years of presentation.

Received letters of 8 Dec. through [Charles] Babbage, including interesting work on statistical returns for Netherlands. Rejoices at prospect of new observatory in Brussels. Promises to do his utmost to help. Honored to be correspondent of Academy of Brussels. Requests AQ address further letters to JH as 'President of Astronomical Society.'

May not be able to separate double stars with the twenty foot reflector. Is reviewing nebulae. Regrets [Josef] Fraunhofer did not live to see WS's work. Speaks of standard catalogue of 2881 stars as joint labor of all observatories. Interested in bright stars with minute companions.

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.

Has more leisure after resigning as Secretary to the Royal Society. Is sending his and [James] South's magnitude scales and positions of observation for WS to compare. Lists common double stars and offers means of comparison. Remarks on 'new star,' the fifth star in the trapezoid of Orion.

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.
