Regrets not having seen JH in England. Discusses horary observations. Lists current projects. Talks about C. F. Gauss's reactions to magnetic observations by JH in two hemispheres and difference of lines for Europe and America. Gives results for August meteors.

System of meteorological observation works well but no English station. AQ is willing to publish results in England if need be. Points out additional observers for September.

Discusses meteorological observations. Stations increased from 26 to 28. Talks about 36 hours versus 24 hours periodical observations and asks for JH's opinion.

Discusses advantages and disadvantages of 24 versus 36 hour series in meteorological observations. R.S.L. officially endorses 24 hours, but AQ should continue 36 hours if best for him. Does not possess the Comptes rendus of French Institute and cannot therefore see No. 413. Will attempt to procure sight of it. Asks AQ to return [P. F.] Verhulst's work to him. Expresses respect for AQ's work. Asks for understanding if JH does not answer every letter promptly.

As 'perpetual Secretary' of the Academy, AQ expresses thanks for JH's work 'On the Advantages to be Obtained by a Revision and Re-arrangement of the Constellations.'

Thanks for letter of 3 December and for encouragement. Informs JH that 30 observatories participated in observation of winter solstice. Is beginning to study humans in their different relations.

Sends works on meteorology and instructions for natural periodic phenomena. More proselytes in horary observations. Asks for JH's recommendations for those observing meteors in the other hemisphere.

Thanks JH for interest taken in periodic phenomena. Discusses train information and preferred hotel accommodations for JH's visit.

Continues horary observations suggested by JH. Also magnetic observations. Discusses observations of migration of birds. November has been cloudy so far and meteors cannot be seen.

Has succeeded in increasing stations around Alps for meteorological observations. [G. B.] Airy is very obliging. Hopes one day to collect all meteorological observations in Sur le climat de la Belgique.

Has worked hard to augment number of stations for horary observations. Now close to 80. Asks JH's advice whether the R.S.L. or B.A.A.S. would print his observations.

Thanks for letter regarding equinoxes and solstices. Intends to work on physical phenomena of globe. Resumes meteorological observations. Awaits Cape Results.

Deprived of news from JH. Works on physical phenomena of globe. Calls attention to [J. C. A.] Peltier's work on electricity of air of barometer. Asks JH to please write soon.

Thanks JH for introducing him to Robert Kane. Hears that JH will publish Cape results. Impatient to see them. Mentions JH's philosophical work.

Hopes JH has received letter thanking JH for Cape Results. Sends meteorological work. Hopes to quit barometric wave observations of atmospheric waves. Has worked with aides on meteorological variations. AQ's mother died.

Lists volumes for JH sent to R.S.L. One includes observations of transit instrument of 1836-1839. Also follow-up on climate of Belgium. Thanks for wonderful reception in London.

Congratulations on marriage of JH's daughter Caroline Herschel. Expects JH has received works sent 1852-12-11. Sends more but assures JH he must not read everything.

Sends list of works received on an official form. Followed by letter. Suffers deeply from death of his wife, daughter, and her son. Had hoped to see JH in London, but JH was absent.

Hopes he has not lost JH's friendship. AQ's son left military to help AQ. Death of Prince Albert was a shock.

Cruel illness has kept him from work for a while. Just finished Histoire des sciences mathématique et physique chez les belges. AQ's son works with proper motion, double and multiple stars, and absolute positions.
