North following this, is a double star of the 4th class ; but its stars are so ex- 
tremely faint, that it is not measurable with this instrument.

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 0 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 0 6' different 
from the present. (H.)
