Burnham: Measures of Proper Motion Stars 
The proper motions are given in A. G. Berlin: 
A o"i02 in 233?9 
B 0.096 in 238.7 
This is a system of the 61 Cygni type. 
No third star available for proper motion.

As it appears that one of these stars has a small proper 
motion, I have connected a faint star to determine which of the 
two is moving.

The change in the angle and distance of BD agrees with the 
proper motion of A. Further measures should be made of 
this, and the nearer star C.
