In order to compare the observed values with the hypothe- 

 tical values, the third column is added here. As the computed 

 densities are sys-

 than the ob- 

 served, we may 

 suspect the cor- 

 rectness of the 30 

 above formula. 



Next, let us 20 

 observe the dis-

of their densities, the actual counting give the following results.

Here again the graphical representation of these results is 

 given in Fig. IV and as a result of the examination of this,
