The change shown in the distance of C is not likely to be 
real; the first measure is only a single night. 
From positions by Ho (2), Doo (2) and P (7), making alto¬ 
gether measures on 43 n, we have for the proper motion of B: 
0^250 in 359?7

As a further check on this extraordinary motion of a very 
small star, I have connected with it one still fainter.

There is no indication of proper motion in A or in the com¬ 
parison star, DM (2°) 3444, from these and the measures of 
1890.
