but the early measure is on a single night.

From four positions on nn by 3 and Doo (1877-1912), the 
proper motion of a Orionis is : 
o?o68 in 39? 3 
A continuation of the measures of this and two nearer faint 
companions will confirm this value. 
From meridian observations we have:

The measure of 1783 is obviously largely in error. The three 
positions by 3 (1879-1911) give for the proper motion of the 
bright star: 
o"o62 in 289?2 
It is not probable that the faint star, B, has any sensible 
movement. There is no othe 
r star near 
it.

The distant Herschel companion appears to have the same 
proper motion as the large star. The values of this movement 
from meridian observation are :

From all the measures of both companions (1840-1911), the 
corrected proper motion of 6 Aurigae is: 
AC R. A. + o'(039 Decl. — o?o66

Therefore the annual movement is:
