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].
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].
Accepts an invitation to dine with GA, and adds comments about problems JH is having with his vision.
No summary available.
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].
Offers a few ideas to GA [see GA's 1863-2-9], but does not have a coherent explanation.
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.
Explains how to detect errors in catalogued positions of stars. List of new nebulae in [G. F. J. A.] Auwers's catalogue.
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.
A letter of introduction asking GA to admit Major Robertson and his sisters to the observatory.
Comments on GA's activity in correcting the calculation errors [see GA's 1863-6-2].
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.
Was surprised at the large vote in support of a parliamentary bill to abolish the British Standard of weights and measures; JH hopes bill will not pass.
Thanks GA for receipt of some Royal Observatory publications; is still pushing the British metrical standard based on the length of the earth's polar axis [see JH's 1860-3-2].
Comments on the ease of calculation in geodesy in JH's version of the English system of units, and asks GA for some clarifications as JH prepares the seventh edition of his Outlines Astr.
