One of these stars, probably the larger, has a small proper 
motion. The measures of AB (1829-1910) give for the ap¬ 
parent motion of A: 
o"o46 in 2?4 
There is no sensible change in BC (P511).

The change in position-angle seems to confirm the proper 
motion given to A in G. C. Part II. The only other measures 
are my own in 1903.

Third star measured to determine which of the nearly equal 
components has the proper motion. The apparent motion of 
A from the measures of AB (1830-1909) 
is:

The 9.2 m star measured from B is DM (36°) 349. The 
measures of this tend to show that B has no proper motion, and 
that the change in AB is 
wholly due to the proper motion of 
the principal star. The observations should be continued.

correct.
