other, I have measured a third and much fainter star:

From the measures of D by 02 and P on 29 nights, the real 
proper motion of the large star is : 
o"o54 in ii6?4 
It is specially important that the measures of AC should be 
continued. 
The proper motion is given from meridian observations:

The five positions by Eng., A and P (1891-1907) give for the 
proper motion of the primary: 
0^252 in 2 I 2?7 
This movement from meridian observations is somewhat 
uncertain in amount.

The companion star, however, is large enough to have 
possibly a small motion of its own; and I have connected with 
it a third star. A set of measures a few years hence will show 
at once whether or not B is fixed.

Further measures are required to show whether or not these 
stars are moving together. 
The proper motion of 21 Cassiopeiae is small.
