Material sent by JH [see JH's 1862-4-2] arrived safely.
Material sent by JH [see JH's 1862-4-2] arrived safely.
Acknowledgment of receipt of more material from JH [see GA's 1862-4-3].
Needs to know, from JH, the date of the nebula observations [see GA's 1862-4-9].
Responds carefully to the question of observational, and reduction, dates [see GA's 1862-4-12].
Acknowledges receipt of more material from JH [see JH's 1862-4-13].
Has now sent the last of the nebula observations to be reduced for printing [see GA's 1862-4-16].
Sends JH a copy of the form to be used for reduced observations [see JH's 1862-4-17].
Approves of form for reduced observations [see GA's 1862-4-24] and sends GA payment against expenses.
Acknowledges receipt of payment [see JH's 1862-4-25]; asks for final approval of printing structure for the nebula catalogue.
Provides final intended structure of the nebula catalogue page [see GA's 1862-4-26].
Seeks clarification of the position of one of the listed nebulae [see JH's 1862-4-30].
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]?
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.
