Scientific Intelliffence, 



There appears to be some error in the Naples observations, as the error of 

 the tables in latitude comes out with a contrary sign. The Konigsberg 

 observation is taken from Mr Bessel's observations for the year 1826, bat 

 it seems that there is an error of one minute in printing. 



The following are the elements which I have obtained from Delambre's 

 Tables of the Sun, and Damoiseau's Tables of 1824 for the Moon. In adopt- 

 ing the tables of Damoiseau, I have reduced the results from the decimal, 

 to the sexagesimal division of the circle.
