From the two positions the proper motion of y Orionis is: 
o"o70 in 358:3 
If the measures are substantially correct, the motion is 
practically all in declination. Further observations of the small 
star should be made. This movement from meridian observa¬ 
tions appears to be uncertain in both amount and direction. 
The separate results differ from each other as well as from 
that given above.

It is more than probable that the apparent change in distance 
is due solely to the proper motion of the large star, although 
the other is bright enough to have some motion of its own. 
This is DM (34 0 ) 1049. The proper motion of </> Aurigae is 
given from meridian positions:
