Sending his Magnetic and Meteorological Annual for 1842. Any publications in exchange should be addressed to the Institute of Mines, St. Petersburg.
Reports in considerable detail on magnetical and meteorological observation in Russia. Supports the idea of international conference of leaders in such work.
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.
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.
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.
