Summary:

As the error of the African chronometer is only 0m 1.1s fast on Cape mean time, he sends it. James Adamson is with TM or TM would avail himself of JH's invitation. The comet was superb last night. A most interesting phenomenon last night was the motion of the comet's nucleus over a small star.

Lack of rest prevented him calling this morning, but would like to come this evening and stay the night. Comet did not appear so round last night. There was a terrible wind. Happy with how the wall and the building protected JH's 20-ft reflecting telescope from high winds.
