This star has undoubtedly increased in distance. In 1783 
it was barely separated with 460. M. Struve, in 1819, 
observed the angle of position with no higher power than 
126. However this is too small a power to excite great 
confidence in the measures of so close an object. The po- 
sition appears subject to a slow but regular variation, if our 
measures be correct.
