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' 5/ (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° 18' 

 or — 4°. 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.)
