Epoch 1825.25. 
There is a considerable change in the position of the close 
star since the year 1823. At that time ( 1823.28 ) the angle 
was 68° 39' sf (See Phil. Trans. 1824. Part III.) Hence it 
appears that the small star has continued its motion in the 
direction there assigned to it ; and, if we may confide suffi- 
ciently in both data, with an accelerated velocity, for the 
computed motion corresponding to an interval of 2.0 years 
would be — 1°. 148, whereas the observations make it — 4 0 18' 
or — 4 0 . 3. Meanwhile the direction of the motion is as pre- 
dicted, and we may therefore regard the reality of this star's 
rotation as fully confirmed. (H.)
