That B has no motion seems to be certain from the several 
measures of BC during the past 25 years. In further verifica¬ 
tion of this, I have measured a third small star D.

These stars are DM (30°) 233 and 232, and the magnitudes 
8.1 and 9.3.

A similar pair, 15 s p and 6' s, was at first measured for the 
other:

The primary is reddish. B and C are 
respectively DM (59 0 ) 
273 and 276. 
In A. G. 
ITels. the DM numbers 274 and 273 seem 
to be transposed. With this correction
