other positions, and the apparent motion of A, are given in Part 
II of the General Catalogue.

From the four positions of these stars (1875-1910), one of 
them has a proper motion of o"os8 in 286 °6 (± 180°) ; further 
measures of the faint star will show which one it is.

may not be real.

I have shown that one of the Struve components has a proper 
motion of o".22$ in ioi?o (± 180°). As they are of nearly the 
same magnitude, it is as likely to be in one as the other. I 
have therefore connected a third star, a remeasurement of 
which after a few years will show at once which one of the 
larger stars is in motion.
