Mean Result. 

 Position 11° 17' sf (42 Obs.); Distance 2". 716 (21 Obs.) ; 



Epoch 1825.30. 



This position, compared with that of 1822.44, gives a 

 motion of + 2** 53'. The supposition of an annual motion of 

 + o°.30, assigned in the former Paper, would give + o°.54'. 

 The present observations therefore confirm this motion fully 

 in point of reality, and direction, but indicate an acceleration 

 which (considering the number of observations) may have 

 some claims to probability. The distances disagree more 

 than might have been expected. (H.)
