Position 6i° 2' sp or nf (35 Obs.) ; Epoch 1825.252 ; 
Distance 4".33o (30 Obs.j ; Epoch 1825.47. 
The position of this star, as determined for the mean epoch 
1820.97, is 6o°.29, or 6o° 18' sp or nf (Phil. Trans. 1824, 
III. p. 271.) It is now 6i° 2'. The change in 4.55 years is 
— o° 44', instead of — 2 0 36', 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.)
