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].

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].
JH wants to avoid using the meter in England; asks GA for the results of A. R. Clarke's calculations on the figure of the earth [see GA's 1863-10-7].
