Mean Result. 
Position 6o° 38' sp (20 Obs.); Distance 2o".25i ( 15 Obs.) ; 
Epoch 1826.09. 
Our former measures of this star gave, Position 6i° 3' sp; 
Distance 19".454; Epoch 1822.04; the former according 
sufficiently with the present determination ; the latter differ- 
ing more than might be expected, viz. nearly 8-tenths of a 
second : whether this arise from a real motion of one of 
the stars, or from erroneous observation, remains to be 
ascertained.
