As it is uncertain which of the Struve components is moving, 
I have connected a third small star.

I have previously given in the General Catalogue the proper 
motion of x Cygni from the measures of the distant star, D 
(1851-1883).

From the single measure of C by HI, and the three ft 
positions, on ion (1876-1911), we have the proper motion of 
x Cygni: 
Measures of AC 0^474 in 22°. 2 
Measures of AD 0.475 in 17.8
