The only other position is that in Part II of the General 
Catalogue. 
A is given a small proper motion: 
Battermann o"oi7 in 96?7 
Further measures of C will give a new and better value.

From six positions of these small stars by III and (I (1878- ! 
1907) we have for the proper motion of 70 Ophiuchi: 
Measures of Aa i'.'o65 in i68?3 
Measures of Ad 1.045 > n 168.3 
Some of the values in the star catalogues are: 
Auwers F'126 in 170^0 
Boss 1.123 in 169.9 
Newcomb 1.127 in 166.9 
These measures are continued for further improvement in j 
the value of the proper motion of the binary:
