It is evident the small star does not belong to the other. 
The proper motion of A is given:

A continuation of the measures will give an independent 
value.

The apparent change in distance since 1825 requires con¬ 
firmation. The only other more recent measures are discordant. 
In a low-power field nf is h 3226. This is too faint and 
indefinite for accurate measures.
