There is a notable alteration perceivable in the position of 
this star. A measure on the 1st of January, 1783, marked 
“ very exact," makes the angle 43 0 54' nf, and the distance at 
the same time was found to be 6".25. The change of position 
amounts to — 6° 50', being — o°.i66 per annum, retrograde. 
Future observations must decide on the reality of this motion, 
and whether this is entitled to more than a provisional place 
among the Binary stars. (H.)
