About some major variations in terrestrial magnetism readings.
The reductions are essentially complete; encourages JH in his part of the work and concludes 'It will be a noble work' [see JH's 1862-11-5].
Astronomische Nachrichten 1392 compares positions of forty nebulae by G. F. J. A. von Auwers, H. L. d'Arrest, and P. E. Laugier. Calculations for JH's [Catalogue of] Nebulae are complete and ready for inspection.
Accounts for money spent in reducing JH's catalogue of nebulae. Encloses sample page from catalogue and Astronomische Nachrichten No. 1392 [see JH's 1862-11-18].
Invites JH to R.A.S. dinner on 9 Jan. to meet Sir G. C. Lewis.
Concerning Thomas Maclear.
Is sending JH the completed sheets of nebula reductions for printing [see JH's 1863-2-6].
Sends a final accounting for the calculating work done at the Royal Observatory on JH's nebula catalogue [see JH's 1863-2-7].
Giving results (including diagram) of a comparison of earth currents and magnetometer disturbances.
Will take into account JH's suggestions [see JH's 1863-2-13] and see where this leads.
Is JH interested in seeing G. F. J. A. Auwers's catalogue of JH's and William Herschel's nebulae?
Did JH receive G. F. J. A. von Auwers's catalog of JH's and William Herschel's nebulae?
Sends copy of G. F. J. A. von Auwers's catalog of JH's and William Herschel's nebulae. Observatory has another copy. Notes odd lines seen in 'Refraction Spectra of 11 stars.'
Refraction spectra of six stars exhibit lines corresponding with 'Solar Line F.'
Expect some errors in calculations of positions for JH's catalogue of nebulae. Suggestions on format.
Does JH need the original calculation sheets to deal with the errors in the nebula catalogue [see GA's 1863-2-23]?
Addresses each error JH discovered in reduction of JH's catalogue of nebulae [see JH's 1863-5-15].
Is working on the correction of calculation errors [see JH's 1863-5-31]; GA and his assistants will deal with the problem of proofreading.
Responds to JH [see JH's 1863-6-2] about basic rules for admission to the observatory [for JH's future guidance]; GA discourages the visit of ladies 'who understand nothing and learn nothing.'
Correcting work is gradually drawing to a close [see JH's 1863-6-4].
