The comparison star might well have 
some proper motion so 
far as magnitude is concerned'. In this 
instance the motion, if 
any, is small. For the proper motion of

The relation of these stars in some of the catalogues is not 
consistent with the micrometer positions, nor with the recog¬ 
nised proper motion.

To show hereafter whether or not B has any proper motion, 
I have connected it with a 11.5 m star.

B is Lalande 5994, and from meridian observations, has no 
proper motion. The only measures are : 
1894.03 i8o?oi 175^92 2n Eng 
1907.89 180.84 I7S-63 3 n P 
These positions give for the proper motion of A: 
o"i 64 in 97?9 
If these measures are combined with the meridian positions 
in A. G. Berlin and Cin. 13, the proper motion is: 
o"i 84 in iii?6 
Some of the values from catalogue places are:

As a further contribution to this matter in the future, I have 
connected each with a faint star which it is practically certain 
has no sensible proper motion.

If the large star has any proper motion, it is very small and 
very uncertain.

From these positions the apparent proper motion of 
x Ceti is: 
o"323 in 74?4 
The motion from meridian observations seems to be too small. 
It is not probable that the small star, DM (2 0 ) 521, 
has any 
sensible movement. It is 
given in A. G. Albany, Schjellerup 
and other star catalogues.
