STUDIES IN STELLAR STATISTICS. II. 27 
The principal results of table 3 are here confirmed. The diver- 
ging behavior of the Bo stars brighter than the 5" magnitude is again 
manifested. For the other subclasses there seems to be no surely 
established difference between the results for different classes of magni- 
tude. This is most clearly found from the values of the absolute 
magnitude (M), which for stars brighter than the 5" magnitude differ 
only by some tenths of a magnitude from the values found from all 
stars brighter than the sixth magnitude. 
The order of the subclasses 
Bi, be. Bs. Ds, Bo 
? 
is here confirmed. Roughly speaking we may divide the B stars into 
two principal groups: The stars belonging to the subclasses Bı and 
B2 having an absolute magnitude amounting to — 4*,3 (corresponding 
to R =  Siriometers) and the stars belonging to the subclasses Bs, 
Bs and Bo an absolute magnitude equal to — 2”.s (corresponding to 
R = 3.3 Siriometers). 
The total number of B-stars brighter than the sixth magnitude 
is 479, 
12. Antapex. From the obtained values of U": R, V'':R and 
W'':R the coordinates of the antapex may be deduced. 
In the following table I give these values for each one of the 
subclasses, separately computed for the stars brighter than the 5° 
magnitude and for all stars brighter than, the 6" magnitude. In the 
2*, 3" and 4" column I give moreover the values of the rectilinear 
spherical coordinates of the antapex.
