The three positions (1879-1911) give for the proper motion 
of the large star: 
o"o65 in 49! 7 
Further measures are needed for a final value.

There is probably an error of 10" in Dembowski’s distance 
of 58"49, or perhaps one-half a revolution giving 47'.'95 for 
the distance. C is DM (17 0 ) 2936.

One of the components of 2 1993 has a proper motion of 
0"76 in about 38° (± 180 0 ) . I have therefore connected a 
distant star.
