The measures of A and (3 in 1901 give the relative motion of 
A as in Part II of the General Catalogue:

The only other measure of AC is:

Assuming C to be fixed, as it probably is, the proper motion 
of A from the two positions is : 
o"i 67 in 90?5 
To determine this hereafter, I have measured a small star 
from C:

in the small star B. The later measures indicate no change in
