Burnham: Measures of Proper Motion Stars 
The proper motion of A given in the General Catalogue from 
the measures of AB (1831-1902) will not be sensibly changed 
by the later positions :

A comparison of this position with Lamont and A. G. indi¬ 
cates a proper motion of o"o6i in declination for one of the 
stars. The 7.6 m comparison star has a 13 m companion:
