The relative motion of A and B is known with great accuracy. 
From the measures of AB the apparent motion of A is: 
o"25i in ii8?5 
The third star, measured from each, will show hereafter how 
this motion is to he divided for the bright stars. 
The proper motion of A from meridian positions is given:

The large common proper motion of the bright stars is well 
known. For future use I have connected the nearest outside 
star.

kid 56 (No. 1142) should be in the field. There must be a 
large error in the Harvard place. I could not find it any where 
in the vicinity.

The proper motion, if any, is very small, and probably com 
mon to both stars.

correction to the large proper motion of 6 Trianguli.
