From the (3 measures of the faint star on ten nights (187S- 
1912) we have for the proper motion of (3 Orionis: 
o"o22 in I03?9 
It is not probable that this value will be very materially 
changed, but the small star is not easy to measure, and the 
motion is small, and therefore the measures should be con¬ 
tinued. The results from meridian observations are singularly 
discordant in amount as well as direction:

According to Auwers the proper motion of the large star is 
nearly all in Decl.; while the 
measures 
of AB and AD 
agree 
in placing it principally in 
RA. A 
continuation of 
these 
positions should give the real motion, which is certainly much 
larger than the meridian value.

This position udien compared with that of 02 from measures 
on 27 n (1854-1911) should give the proper motion of the bright 
star with the highest degree of accuracy. 
o'.'4i4 in i65?6 
This will be confirmed later when the nearer and fainter stars 
are sufficiently measured.

My three sets of measures of the small star C (1879-1908) 
j give, as they should do, practically the same value of the 
proper motion of the bright star as that given by the measures
