In the measures by Dembowski, C is treated as the primary. 
As printed in Part I of the General Catalogue it is therefore 
180 0 in error. 
The measures of C do not indicate any material change, and 
therefore if the proper motion given in Part II is correct, the 
three stars have the same movement. To settle this hereafter, 
I have measured a fourth star.

A and C are respectively DM (52 0 ) 297 and (53 0 ) 266; and 
the R. A. should be as given here. The only other measures are 
those given in the General Catalogue.

The components of the triple, A, B and C have a common 
proper motion. This, from the measures of D (1832-1908), is: 
o"o45 in ioo!6 
All the other measures of the three principal stars are given 
in G. C. Part II. 
For greater certainty I have connected another faint star:

It is now certain that A and B have the same large proper 
motion. The third star is connected for an independent value 
of this motion hereafter.
