will not be materially changed.

For the proper motion of A. This is a system of the 61 
Cygni type, the two equal components having slightly different 
proper motions. From the star catalogues we have: 
Stumpe o"897 in 98!7 
Porter 0.887 in 98.4 
Paris 0.929 in 97.9 
From the measures of AB (1876-1905) the relative motion 
of B is:

I have given in the General Catalogue the proper motion of 
the close pair from the measures of C (1831-1904). The later 
observations will not sensibly change that result. 
o"o36 in 205?7 
There are no other measures of D. 
Further measures of the faint stars will give an independent 
value of the proper motion of A.

2 3060 appears to belong to the 6r Cygni type, with a very 
small relative rectilinear motion, and I have therefore meas¬ 
ured a third star for the proper motion of A. This has been 
given:
