The preceding table proves most satisfactorily the regular motion 

 of the Pole Star in declination between 1755 and 1825, and also 

 the extreme degree of exactness of the determinations of the de- 

 clination by observation. Therefore, as far as observation is con- 

 cerned, the latter part of the value of the luni-solar precession above 

 determined, viz. 50,"381 + 0,035 u is probably very small. That 

 it is also insensible from proper motion in declination, is likely from 

 the unchangeableness of the relative positions of Polaris and its 

 attendant. Hence 50",381 may be considered a very near deter- 

 mination of the luni-solar precession in 1 788.
