Still has not heard from JH. Has put much effort into horary observations of solstices and equinoxes. Sends JH articles by AQ on temperatures of earth. Will send magnetic observations.

Welcomes JH back to England. Proof that AQ never ceased thinking of JH is that AQ never quit his horary observations. Has sent books to R.S.L. for JH. Has restarted his notices on meteors. Is determining their longitude in relation to Greenwich. [Richard] Sheepshanks brought AQ JH's portrait and bust.
Thanks for two letters. Updates JH on observatories participating in horary observations. Proposes to reduce observations. Sends second part of Brussel's annals and other works. Discusses a phenomenon on 10 August. Mentions several observations of the Aurorae Borealis.
Sends latest publications. Has received highly surprizing letter on meteors by Mr. Wood. Discusses 'famous apparitions.'
Has received JH's letter of 29 October. No need to thank for meteorological observations. Done in interest of science. Sends measurements of December 1837 and other bulletins. Asks JH to send his extra copy of AQ's Correspondence mathématique of July 1838 to [J. D.] Robertson. Asks more about satellites of Saturn. Thanks for information on meteors.
Discusses observation of meteors. Sends observations of last solstice and details of that night's constellations. Offers results of observations of occultation of Gamma[?] Tauri[?].
No summary available.
Sends continuation of Belgian meteorological observations. Just finished magnetic observations. Plans to continue certain ones. Regrets being alone, without aids, 'in front of the transit instrument, the mural circle and the equatorial.'
Addresses a few last words before departing for Italy with his wife. Sends 3 memoirs just published. Will be in Paris to observe meteors. Proposes to redo terrestrial magnetism observations in Italy.
Is comparing 'points and measures' of new stations with [François] Arago. Also busy with daguerreotypes. Thanks for encouragements. Has necessary instruments for meteorological and magnetical observations. Mentions work done and astronomers met on Italy trip. Discusses Prince Albert.
Sends publications from Royal Academy and Brussels Observatory. Asks 'particular indulgence' for one about vapors. Is now able to do observations required by R.S.L. A Gauss instrument has been mounted. Gives times of observations each day. Continues horary observations.
Still waits for the instrument that Edward Sabine had built. Wishes to make actinometer observations but has no instrument. Asks JH to have one made. Sends observations from Italy trip to Sabine to present to R.S.L. Continues horary observations.
Royal Academy of Sciences and Fine Arts acknowledges receipt of JH's 'On the Chemical Action of the Rays of the Solar Spectrum.'
Refers to meteors of August. JH's account similar to [Edward] Herrick's. More meteors seen in America. Sends magnetic and meteorological works. Had hoped to go to Glasgow.
Says JH's interest in AQ's work has been source of motivation. Notes that on 21 September and 21 December, aurora borealis and magnetic perturbations have been spotted. Asks where to procure an actinometer in England.
Is thrilled about 4 aides to help with meteorological and magnetic observations. Points out that number of stations participating in horary observations increased to 22. Lists them. Hopes to go to Plymouth [B.A.A.S. meeting].
Announces results of last observations, both magnetic and meteorological. Hopes to see JH.
Found letter sent at the R.S.L. Left with William Whewell for Plymouth. Results are forthcoming on meteorological observations that JH suggested. Regrets not seeing JH in England.
Presents best wishes to Lady Herschel. Regrets not having met on account of meeting with [G. B.] Airy at Greenwich. Is keeping four pictures of JH and has offered 2 additional ones to Prince Albert.
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.
