224 Primary and Secondarij Reduplication Series 



(7) Nature of mating DfN x dFn. 



The value of I is again very near that of n if not equal to it. 

 Assuming I = n, the observed secondary reduplication series can be 

 shown to depend upon the complicated series 



19 : 10 : 10 : 19 

 10 : 57 : 57 : 10 

 10 : 19 : 19 : 10. 



These complicated series are not very different from the simple series 



2:1:1:2 

 1:6:6:1 

 1:2:2:1, 



which would be obtained if the observed secondary series were 



Below are given for purposes of comparison the actual numbers 

 obtained (cf. (3), p. 89), the numbers to be expected upon the above 

 hypothesis, and the numbers to be expected on Trow's special hypo- 

 thesis.
