 Distance = 4". 609 | 5 Obs. , Diff. = o''.456. Tolerably steady. 



The distance, 5". 580, taken September 29, 1824, is probably large ; still as the 

 observations were made under favourable circumstances, I cannot reconcile myself 

 to their rejection. 



Mean Result. 

 Position 84° 59' np {9,5 Obs.) ; Epoch 1825.08 ; 

 Distance 4*. 9 79 (25 Obs.) ; Epoch 1825.40. 



In 1783.33 the position was found to be 78° 42' np, so that 

 an angle of + 6° 17' seems to have been described since that 

 epoch, or +o**.i28 per annum. This star then should be 

 re-examined after an interval of 10 or 20 years, to ascertain 

 whether the presumed motion be real, or not. (H.)
