Ready to send nebula data to GA for reduction; question of dates need decisions [see GA's 1862-1-30].
Ready to send nebula data to GA for reduction; question of dates need decisions [see GA's 1862-1-30].
Is sending first part of observational data for nebula catalogue [see GA's 1862-3-31].
Forgot, in earlier note [see JH's 1862-4-2], to indicate agreement with GA's suggestions [see GA's 1862-3-31].
Responds carefully to the question of observational, and reduction, dates [see GA's 1862-4-12].
Has now sent the last of the nebula observations to be reduced for printing [see GA's 1862-4-16].
Approves of form for reduced observations [see GA's 1862-4-24] and sends GA payment against expenses.
Provides final intended structure of the nebula catalogue page [see GA's 1862-4-26].
Provides the information in response to GA's request for the position of one nebula [see GA's 1862-5-27].
The R.S.L. grant is almost used up; how much more money will be needed for the nebula catalogue [see GA's 1862-6-25]?
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].
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].
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.
Sends GA a list of errors found in the sheets for the nebula catalogue [see GA 1863-5-14].
