If the principal star has any proper motion, the companion is 
moving with it. Unfortunately there is no third star near 
enough for comparison. The supposed proper motion should 
be confirmed.

The four positions given, including South in 1829, make the 
apparent motion of B : 
o"i53 in 27°.o 
It is obvious from the magnitudes that this proper motion 
may be in either, or both. I have, therefore, connected a third 
star:

This star wrongly identified from W2 in the General Cata¬ 
logue, and the place given is that of DM (18 0 ) 2788 (8.7). It 
should be (18°) 2786 (8.3), which is closely sp the other. The 
correct place (1880) is given here. The proper motion given 
in the General Catalogue is that of 2788. 
The principal star of S 655 has a small proper motion. The 
later positions by Doo and P (1897-1911) give: 
o"o 76 in 291° I 
Or, if the measure by South is used:
