These results are plotted in Chart VII. It will be noted 
that for n<10, the value of © is between 3.10 and 3.80 what- 
ever the value of w. Thus in all cases which are of practical 
interest, ® does not vary greatly from its value in the expon- 
ential model, i.e. 3.5. 
Values of (Rem - Re)/Reom

Then, for given values of yc and (¢-p) and the values of ©, 
calculated in $ 535, we can derive the following table.
