Response to questions on magnetic circular sent out by JH [see JH's 1844-12-5].
Sends first report of Astronomical Society council and James South's corrections for June to Dec. 1821.
Announces formation of the Astronomical Society. Will be pleased to propose [CG] as an associate.
Has received letter of 3 June 1820 reporting on the new circle at Göttingen Observatory. Will read it to the Astronomical Society and propose CG as associate. Sends some JH publications.
CG has been elected associate of the Astronomical Society. Hopes the benefits will be mutual. Details of the prize subject for the present year. Has read CG's communications on the Reichenbach circle to the Society, where it evoked great interest. Comments on this. CG's certificate has been signed by Fearon Fallows, newly appointed Cape astronomer.
Sends first annual report of the Astronomical Society and will be sending one of JH's papers ['On the Aberrations of Compound Lenses and Object-glasses,' RSPT (1821), 222-67], which JH summarizes.
Note to accompany the sending of a number of papers; comments on the orbits of double stars.
Note regarding the translation into German of JH's Light, which JH notes has already appeared in French.
Unable to visit, but has sent two papers on the orbits of double stars. Discusses double stars, noting that four double stars are now known to orbit with periods less than a century long. Wilhelm Olbers is seriously ill.
Informs CG of the awarding to CG of the Copley medal for CG's magnetic researches; hopes that the British government will support such magnetic researches around globe.
Comments on CG's paper on the south magnetic pole, and on British efforts now underway to make magnetic observations.
The instructions for making magnetic and meteorological observations are to be revised. JH asks CG's advice about this.
[Writing as an addendum to a letter on magnetic observatories circulated by Edward Sabine], JH states that various publication concerning magnetic observations will be sent to CG.
CG having now received the Greenwich and Toronto observations, JH invites CG to write further material for the forthcoming publication.
Writing on behalf of the B.A.A.S. Magnetic and Meteorological Committee, JH invites CG to submit a reply to the materials sent to him.
Has not seen enough magnetical and meteorological observations to judge their effectiveness. Encourages British government to continue these, but perhaps reduce frequency.
Has been absent the whole summer and fears that his letter acknowledging his election to the Astronomical Society may have gone astray. Is grateful for the honor. Sends a paper of his own on a new method of making observations with the heliotrope. Comments on the usefulness of this instrument.
Many thanks for his communications, especially for the one on light. This may be translated into German by J. E. E. Schmidt, and he would be grateful if JH would authorize this to be done.
Sends on a copy of JH's orbital elements for Gamma Virginis.
Thanks for his letter informing him of his having been awarded the Copley medal. Was pleased to receive the observations of the magnetic declination and inclination of London. Projected expedition of Captain J. C. Ross pleases him. C. F. Gauss is now preparing the third volume of the Resultate. Would like JH's opinion on one of the papers in this volume. Gives his own views on the magnetic poles.
