Comparing these equations we find the left members to be ap- 
proximately the same for all subclasses. The coefficients of x, y, 2, 
depend, indeed, only on the distribution of the stars in the heavens. 
If the stars are uniformly distributed on all squares, then the nor- 
mal equations accept the simple form (Compare Meddel. Ser. II N:o 8, 
E11): 
0.6618 z = ([ys w'] + [rev]: N , 
0.8533 y = ([yau'] + [yav']) : N , 
0.6793 2 = [7:,0'] : N . 
The deviations from this ideal form give an indication of the 
degree of dissymmetry in the distribution of the observed stars. 
The distribution of the B-stars on different squares is seen from 
the following table:
