Example of the use of the tables. — Let it be required to calculate the apparent 

 place of the 7 satellites for 1789, Oct. 18, 7^ 51"* 54^, to the nearest minute 

 of time and to lOths of a degree. 



* The quantity marked Tj 12°. 58, which is applied to every one of the satellites, is the comple- 

 ment of 11* 17° 25', or geocentric place of Saturn, taken from the Nautical Almanac, for midnight 

 of the required day, and to the nearest minute, which is sufficiently exact. This complement, or 

 12® 35' in conformity with tlie tables, is reduced to decimals of a degree 12°.58. — Orig.
