From the measures of the small stars (1877-1912) we have the 
proper motion of the large star with a high degree of accuracy, 
and this value is not likely to be sensibly changed by future 
measures. In my measures of AE in 1901 (G. C. Part II) there 
is an error in reducing the distance; for 93"49 read 88"6s. 
The measures of the three companions give the annual 
motion of A:

Therefore the corrected proper motion of 3 Equulei is: 
o"ioi in 65?5 
This motion from the star catalogues is decidedly too small: 
Auwers o"o23 in 66?7 
Boss 0.054 in 83.6
