Mean Result. 



Position 86° 46' nf (10 Obs.) ; Epoch 1825.05 ; 



Distance 35".678 (15 Obs.) ; Epoch 1825.06. 



By a mean of two measures in 1783, the position comes 

 out for that epoch 85° 24', differing but 1° 32' from the pre- 

 sent. The distance at the beginning of 1783 was 29'*. 30, 

 and the measure is called very exact; yet an increase of 

 distance to the extent of 6". 38 is beyond probability, a cir- 

 cumstance which proves the occasional occurrence of the 

 micrometrical error already pointed out, even in distances so 

 low as 30". (H.)
