 The small star is bluish, and becomes more distinct by a very slight illumination ; 

 yet it is so faint, that I can obtain no observations of distance. Night extremely 

 clear, and stars on the meridian. 



Mean Result. 

 Position 29° 28' sp (15 Obs.) ; Epoch 1825.20; 

 Distance 19".658 ; Epoch 1825.02. 



The measure of Sir W. H. in 1802 makes the angle of 

 position of this star 31' 34' sp, being only 2° & different 

 from the present. (H.)
