The motion of this star, first pointed out by Sir William 
Herschel in 1804, is thus clearly established. The disa- 
greement. between our observations and M. Struve's is 
rather more than usual (4 0 6') ; but the star is close and diffi- 
cult. The mean annual angular motion is about o°.5io, in 
the direction nfsp , or direct.
