One of the proper motions from A. G. Harv., given in Part 
II of the General Catalogue is manifestly wrong, since there 
is no relative change in the last fifty years. I have therefore 
measured a third star for verification of the proper motion, 
if any, in AB.

There is no star in the Madler place. I have measured one of 
several small stars in the field.

From the measures of the faint star (1879-1912) the proper 
motion of A is :

It is now certain that A and B are moving together, and the 
large change in C is due to that movement. (See G. C. Part II, 
pp. 294, 1058.) 
No material change in AB since 1832. The proper motion of 
<f> Piscium is uncertain from the catalogue positions :

The proper motions of these two stars, Groombridge 267 and 
266, are given in the Greenwich Catalogue for 1890: 
A o"o37 in i04?o 
B 0.032 in 121.8 
There has been no relative change, and therefore the proper 
motions must be exactly the same. For a better determination 
of this motion hereafter, I have measured a third star:
