88 Mr. South’s observations of the apparent distances 
No. CCCCXCI. continued. 
The positions of B and C respectively in 1781, were 
43° 51' sf, and 11 0 19' sf, the former indicating a change of 
8° 7', and the latter of only 2 0 7'. The distances have un- 
dergone little change. 
Here the fixity of the more distant star may be regarded 
as affording presumptive evidence of a motion in the nearer 
one, and that to a considerable amount (-{- o°.202 per annum, 
or direct.) This star therefore merits attention. (H.)

After these measures were secured, the position wire was purposely set to zero. 
The small star is decidedly above the wire, whilst the larger one remains bisected 
by it, during their progress across the field. Night very favourable ; it freezes 
slightly.

In 1783 the position is stated (MSS.) to have been 2 0 36' np, 
and the distance I3".4i. In 1802 the angle was measured at 
3 0 56' np, but (for reasons assigned), this was regarded at the 
time as a manifestly false measure, and the small star was 
judged to be exactly preceding. The total change of angle is 
4 ° 14 ', a considerable quantity for mere error of observation 
in a star of the 3d class, and which (when the observation 
of 1802 is considered ), may lead to a suspicion of a very slow 
relative motion. (H.)
