These measures show that there has been no change since 
1891. Some of the early measures have large errors in the 
position-angle. The proper motion, if any, is very small.

The four sets of measures by A, Franz and P (1876-1912) 
give for the apparent motion of B: 
o'.'o 82 in 76^5 
As these stars are of about the same magnitude, the proper 
motion may be in either or both. I have, therefore, measured 
the nearest third star:

These measures will not sensibly change the value given in 
the General Catalogue for the proper motion of a Andromcdac 
from the positions 1836 to 1903.

A continuation of the measures of the small star will give 
an independent and better value of the proper motion of the 
bright star than that derived from meridian positions. With 
the time interval of 1889-1910 we have:

There is an error in the Cincinnati place of this star. It is 
identical with 2 3065 rej (No. 14). All the measures cited in 
G. C. Part II belong to 2 3065 rej.

As the first position of these stars depends upon a single 
night, the apparent change in distance may not be real.
