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.

Had a parcel from the Admiralty but no word about the tide gauge. Sends the Simon's Bay observations, also the P. P. Barraud chronometer, which loses time at a great rate.
