Mean Result, 



Position 61° 2' sp or nf (ss Obs.) ; Epoch 1825.252 ; 



Distance 4*.330 (30 Obs.j ; Epoch 1825.47. 



The position of this star, as determined for the mean epoch 

 1820.97, is 6o°.29, or 60° 18' sp or nf (Phil. Trans. 1824, 

 III. p. 271.) It is now 61° 2'. The change in 4.55 years is 

 — 0° 44', instead of — 2° 36' y which a computation founded 

 on a mean motion of — o*'.5792 per annum would give. The 

 determination for 1820 can however hardly be relied on for 

 so great a degree of exactness as to bring out a precise 

 quantity. The correspondence in direction is all we can ex- 

 pect, and is a satisfactory confirmation of the motion ascribed 

 to this curious star. (H. )
