The mean right ascension of Canopus, reduced to the 4th 
of January, 1822, by observations made at the beginning of 
the year, is 6 h 20® oo',oo, and by those at the end of the 
year 6 h 19" 59*,95- 
The clock, which stands at a short distance from the tran- 
sit, does not go so well as could be wished. After a great 
deal of lost labour, and by a careful examination of its parts, 
I succeeded in remedying several defects, and at length 
brought it to have a nearly equable rate. The dampness of 
the apartment, especially after rain, may have a sensible 
influence upon the going of the clock, which no artist could 
provide against.
