Position 71 0 46' sf; Distance 7". 503 ; Epoch 1825.54. 
There is considerable discordance among the measures of 
this star at different epochs — that of 1783 making the posi- 
tion 75 0 9' sf, and that of 1802 77 0 54' sf. On the whole, 
there seems ground to believe in a slow motion of about ith 
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.)
