88 ON AN IMPORTANT ERROR IN BOUVARD'S TABLES OF SATURN. [16 



into a single term, 25"'85 sin {^-2^' + 43 '88} 



which T find very closely to represent Bouvard's Table XLII. 



After correcting the above error, and making a proper alteration in 

 the inclination and place of the node, the remaining errors of latitude are 

 in general very small. I subjoin a correct table, to be used instead of 

 Bouvard's. The constant added being 36"'0 instead of 26"'0, it will be 

 necessary to subtract 10"'0 from the final result.
