Will take into account JH's suggestions [see JH's 1863-2-13] and see where this leads.
Is sending JH the completed sheets of nebula reductions for printing [see JH's 1863-2-6].
Is JH interested in seeing G. F. J. A. Auwers's catalogue of JH's and William Herschel's nebulae?
Giving results (including diagram) of a comparison of earth currents and magnetometer disturbances.
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.
Sends a final accounting for the calculating work done at the Royal Observatory on JH's nebula catalogue [see JH's 1863-2-7].
Offers a few ideas to GA [see GA's 1863-2-9], but does not have a coherent explanation.
Once again anxious about completion of nebula catalogue, and about cost over run [see Edward Stone's 1863-1-14].
Acknowledges receipt of nebula catalogue sheets from GA [see GA's 1863-2-6]; apologizes for JH's anxious letter [see JH's 1863-2-6].
Has found a few minor errors in the calculations checked so far [see GA's 1863-2-6]; comments on magnetic tracings JH received from GA.
Might have saved JH some work if he had known what G. F. J. A. Auwers was doing [see GA's 1863-2-20]; has found some more errors in nebula calculations.
