In G. C. Part II, p. 1082, in the proper motion of A, for 
1"086 read o"o86. 
The four sets of measures of C now available (1876-1908) 
give for this motion : 
o"o 83 in 53?6 
From meridian positions: 
Kustner o"o6i in s6?2 
While C is a bright star, there is no reason for supposing that 
it has any sensible proper motion. For greater certainty, I 
have measured the faint star D.

No other measures of C. About 40' np is the interesting 
object, h 2075. This was measured at the Lick Observatory; 
central star not seen here. {Pub. L. O. II p. 166.)

These stars, too faint to be in the DM, 
are about 6' n of the 
8.7m star, DM (42 0 ) 3725. This does 
not agree with the 
description by Lewis in magnitudes, or distance which is given 
as 1 * 55 * As nothing else could be found 
in this vicinity, there 
must be a large error in the place, or in the measures.

I do not find any proper motion given the large star; not in

It is evident from the measures of CD that D has no proper 
motion. The measures of AC by 2 , A and [3 (1831-1910) give 
for the proper motion of AB:
