A comparison of the late positions with that of 1878 indicates 
small proper motion principally in 
declination, instead of 
R. A. as shown by the meridian observations, but the early 
position is on a single night, and therefore further measures 
are needed.

The measures of the small star (1836-1911) should give the 
proper motion of the large star with the highest accuracy. The 
seven positions by 2 , A, HI and ( 3 , from measures on 20 n, give 
the proper motion of 11 Serpentis:
