Our chief data from the work set forth in the preceding paper 

 on the effects of -conjugation are from Experiment 1. In the 

 first column of table 43 are given the coefficients of correlation 

 between members of pairs for the various periods of this experi- 

 ment, as well as certain coefficients from Experiments 2 and 3. 



The coefficients from Experiment 1 are based on the data 

 given in table 29 of the preceding paper (page 379); they can 

 be recomputed* from that table by anyone desiring to test the work. 

 Besides the coefficients for weekly periods, I have given also those 

 obtained by taking for each member the number of fissions for 

 periods of two weeks, for four weeks, and for five weeks. It is 

 important to understand that these latter are not averages, 

 derived in any way from the coefficients for the separate weeks, 

 but are computed directly from the data as to the number of 



TABLE 43 



Coefficients of correlation in rate of fission between the two strains derived from the 

 two members, a and b, of pairs, and of split pairs, in experiments 1, 2 and 3 of the 

 preceding paper {Paramecium caudatum). The coefficients for experiment 1 are 

 computed from the data given in table 29 of the preceding paper, parte 379.
