One of these stars, and presumably the larger, has some 
proper motion. The three sets of measures, on 8 n (1880- 
1912), give for the movement of Lalande 40682: 
o"o57 in i8i?7 
The only value found from meridian positions is the follow¬ 
ing: 
Boss o"o75 in 206^9 
AB and D (12.8) 
For the proper motion of AB. This is given

The change shown by the Cincinnati measure of 1879 is 
probably explained by a large error in that distance.

The large star has no certain proper motion from meridian 
positions:

There is a faint star about 10" from C. 
No change in AB. The measures of the small star must be 
continued for the proper motion of 59 Cygni. This is un¬ 
certain from the star catalogues:
