From the measures of AB the principal star has a proper 
motion of o'.'o65 in about 180°. No other measures of the 
faint star.

The proper motion of X Persci is wholly uncertain, so far 
as meridian observations are concerned: 
Auwers o'.'oos in 2i2?6 
Newcomb 0.033 in 163.2 
Boss 0.021 in 143.1 
The measures of the distant companions show that the 
proper motion of the large star is very small, if any at all, but 
further measures are necessary to give a definite value.

No change in AB. The principal star is given a small proper 
motion:

To determine whether or not AB has any proper motion, I 
have connected two small stars.

For the proper motion of AB, if an}9 I have connected a third 
star. Three small nebulae by Stone sf are too diffused for 
good measures.
