Burnham: Measures of Proper Motion Stars 
Very little change in the large stars. For the proper motion 
of A we have :

The only other position of C is:

These measures imply a proper motion of A : 
o"o55 in 14H5 
If these positions have the usual accuracy, the motion from 
meridian observations is erroneous:
