From five positions of AB by A, Doo and (3 (1876-1911) we 
have for the corrected proper motion of the large star:

Auwers 0.029 in 35.5 
Boss 0.043 in 65.3 
It should be noted that Dembowski’s measure of the other 
distant companion is of A and CD, and not A and C; and in 
my measure in 1880, the distance i6o" 47 should read i6i"04. 
About 2 0 ' up 70 Geminorum is h 456. It is round and small, 
but bisection not very exact. The measures connect it with a 
9.0 m star in the field.

Herschel said this was not identical with 2 1120, and it could 
not be if his description was correct, but probably that was 
erroneous, and it now appears to be the same as 2 1121, with 
error in the estimated angle. It is in the central part of h 459.

2 1121 is the principal star of h 459. Some of the other stars 
of the cluster were remeasured in the hope of finding a small 
star with some proper motion. So far, the differences from the 
results found by Glasenapp are no larger than the probable 
errors in the average set of measures. The observations by 
Glasenapp are:

The proper motion of A from meridian observations seems 
to be much too large. From the measures of the two com¬ 
panions (1901-1911) the motion of that star is:
