Refraction spectra of six stars exhibit lines corresponding with 'Solar Line F.'
Expect some errors in calculations of positions for JH's catalogue of nebulae. Suggestions on format.
Is sending JH a list of 38 nebulae, their positions reduced to 1830, and described using the terms that JH uses. Comments on some of the difficulties in identifying the nebulae, and includes reference to other astronomer's work.
Sends a final accounting for the calculating work done at the Royal Observatory on JH's nebula catalogue [see JH's 1863-2-7].
Recalls translating Outlines Astr. into Chinese. Wishes to visit JH before returning to China.
Heard of JH's 'domestic affliction.' Postpones visit till next week.
