Reports on examination of observations of 1769 of Venus's transit over the sun's disc. Discusses variations at different sites in 'breaking and formation of the black drop,' and possible causes of error in original observations. Will send copy of paper.
Intrigued by discovery of 'willow leav[e]s' on sun's photosphere, bought new telescope eyepiece. Reports observations on 'leav[e]s' and overall 'rice-like' texture of sun under telescope.
In response to a letter from JH [RAS Monthly Notices, 26 (1866), 299-300] giving eye estimations of magnitudes of stars about Epsilon Coronae, suggests that the star JH observed may be 'the new variable' [T Coronae]. Reports Greenwich observations of this new variable star.
In GA's absence, ES reports on the state of completion of the final copy of the nebula catalogue [see JH's 1863-1-13].
As G. B. Airy is in Scotland on vacation, ES sends the requested information [see JH's 1863-7-8].
Gives details of calculations [for JH's catalogue of nebulae]. Three more weeks of work needed.
