The components of H 1810 are among the principal stars of 
h 2182. The DM number in Part I of the General Catalogue 
should be 2607 instead of 2617.

This may 
be a pair 
of the 61 Cygni 
type, the components 
having slightly different proper motions. 
To verify the motion 
of A as given from meridian positions, I have connected a 
faint star.
