MEAN PLACES AND ANNUAL PROPER MOTIONS FOR 1800, DEDUCED FROM 

 PLACES FOR 1755 AND 1845 AND PRECESSIONS FOR 1755, 1800 AND 1845. 



Mr Farley has remarked that one of these stars, viz. e Ursse Minoris, 

 is too near the pole to allow the treatment of it as an ordinary Non-polar 

 Star to be quite satisfactory. In this case it would be preferable to use 

 the formulae for the reduction of star places which are specially appropriate 

 to the Polar Stars. In two other cases, viz. /3 Ursse Minoris and y Cephei, 

 the polar distances, though larger, are sufficiently small to make it expedient 

 to use the same formulae when the greatest degree of accuracy is required.
