In the above, it mighthave been better to have omitted the observations of August 
6, 1818, and January 20, 1819. No difference, however, would have taken place in the 
total results ; and it may be proper here to remark, that no result has been omitted, ex- 
cept some error is clearly shown by the circumstances of the observation ; and this has 
not happened in any thing like ten instances in above 4000 observations.
