Position 18 0 19' np (20 Obs) ; Distance 6". 677 (15 Obs.) ; 
Epoch 1825.57. 
In 1783 the position was 16 0 o' np, and in 1802 16 0 46' 
n p, so that this star has undergone no change. The distance 
too is nearly as it was. (H.)

This star so much resembles the last measured double star (No. 708), that on ob- 
serving it in the field of the telescope, I thought I had perhaps neglected to alter the 
direction of the instrument. The small star bears but the most feeble illumina- 
tion ; and although the night is in every respect favourable for delicate observa- 
tions, still the results must be regarded with some distrust.

Observed when 15 minutes east of the meridian. Night very fine ; but the small 
star will not bear any illumination. Measures of precarious accuracy. 
Mean Result. 
Position 20 0 21' np ; Distance 5".478 ; Epoch 1825.57. 
In 1783 (1783.21) the angle of position was 13 0 o' np. 
Thus in 42.36 years + 7° 21' have been described, being at 
the rate of -|- o°.i73 per annum. (H.)
