Attempts a more accurate estimate of work to be done on nebula catalogue [see JH's 1862-6-27].
Attempts a more accurate estimate of work to be done on nebula catalogue [see JH's 1862-6-27].
In view of the additional costs, should the nebula catalogue be reduced to a 'working list', or should JH go back to the R.S.L. for more money [see GA's 1862-6-29]?
Seeks state of the nebula catalogue so an accurate estimate of the remaining costs may be made [see GA's 1862-8-1].
Expects R.S.L. to provide additional money, but JH will finish work himself rather than go over the amount granted [see GA's 1862-8-12].
Is working on the descriptions of the nebulae for the catalogue [see GA's 1862-9-2].
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].
Asks GA for a copy of G. F. J. A. Auwers's nebula catalogue [see GA's 1862-11-17], and a sample of the nebula listing for JH's catalogue.
Anxious to receive final sheets of nebula catalogue from GA [see GA's 1862-11-19], as JH wants to enter the descriptions and complete the work.
Once again anxious about completion of nebula catalogue, and about cost over run [see Edward Stone's 1863-1-14].
Is sending JH the completed sheets of nebula reductions for printing [see JH's 1863-2-6].
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.
Is JH interested in seeing G. F. J. A. Auwers's catalogue of JH's and William Herschel's nebulae?
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.
Sends GA a list of errors found in the sheets for the nebula catalogue [see GA 1863-5-14].
Provides last list of errors and explains JH's role in detecting them [see GA's 1863-5-26]; is worried about the task of proofreading.
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.
Comments on GA's activity in correcting the calculation errors [see GA's 1863-6-2].
Correcting work is gradually drawing to a close [see JH's 1863-6-4].
Has spent much time on figures and annotations for JH's nebula catalogue [see GA's 1863-6-5]; JH needs information from a paper in GA's hands.
