 Position 71° 46^5/; Distance 7*. 503 ; Epoch 1825.54. 



There is considerable discordance among the measures of 

 this star at different epochs — that of 17S3 making the posi- 

 tion 75° 9' sf, and that of 1802 77° 54' sf. On the whole, 

 there seems ground to believe in a slow motion of about ^-th 

 of a degree per annum in the direction np sf or retrograde 

 ( — o°.i67), while the distance has probably not undergone 

 any sensible change. Future observations must decide the 

 point. (H.)
