Mean Result. 
Position 70° 29' sp (21 Obs.) ; Distance 1' 50 '.700 (21 Obs.) ; 
Epoch 1826.10. 
Our former measures were. Position 71 0 8 ' sp; Distance 
1' 5o".i93 ; Epoch 1821.91 ; agreeing sufficiently with the 
present determinations to render it probable that the star is 
liable to no very important change : it is true, the distance 
here given differs 5-tenths of a second from that arrived at by 
our joint observations, and that it lies in the right direction ; 
still future observations must decide whether the discordance 
between Sir W. Herschel’s measure of distance and our own, 
= 13" ’.77', have any other foundation than instrumental 
error of the micrometer employed in 1783.
