These positions unfortunately depend upon a single observa¬ 
tion. Comparing them with the recent measures, we have for 
the proper motion of A : 
AC R. A. + o"i23 Decl.—0^146 
AD 0.168 0.197 
+ 0.145 —0.171 
Further measures of these stars will decrease the error 
probable in the result given here.

A comparison of the present position of the faint star a with 
the rough setting of 1904 tends to show that it is not moving in 
space with the other.

A and B are relatively fixed. As the proper motion of 100 
Piscium is very uncertain from meridian observations, I have 
connected two faint stars.
