If the single measure of Ho is correct, the components of 2 
1876 have a considerable proper motion; but it does not appear 
to have been recognized in the star catalogues.

For proper motion of AB. This is given from meridian 
positions:

From the three positions by A and (3 (1873-1912) we have 
for the proper motion of one of these stars: 
o"o 76 in I 57?7 (± 180°) 
To determine which, if only one, of these stars has this 
movement, I have connected with each a third small star:
