Burnham: Measures of Proper Motion Stars 
The proper motion of the principal star is said to be: 
A. G. Ber. o".220 in 74^2 
No other measures of C.

No material change in this since 1881, and it is therefore 
certain that the binary has no sensible proper motion.

One of these stars has a proper motion of about o'.'29 in 238° 
(± 180°). The measures should be continued, and a third star 
connected.

These positions tend to prove that the proper motion of A is 
in Declination, as shown from the measures of AB, and not 
in R. A. as given from meridian positions.
