No. 552] INHERITANCE OF FECUNDITY 705 



The different gametic constitutions in respect to fe- 

 cundity which are to be expected in Barred Plymouth 

 Rock males and females are shown in Tables III and IV. 



Of these expected types six (1, 2, 3, 4, 7 and 8) were 

 found and used in the experiments in the case of the 

 males. In the case of the female class 5 birds were the 

 only ones not actually tested out in the breeding experi- 

 ments. Birds undoubtedly belonging to each of the 

 omitted classes have been reared in the course of the ex- 

 periments, but not yet submitted to continued breeding 

 test. 



The gametic constitutions of pure Cornish Indian 

 Games in respect to fecundity are given in Tables V 

 and VI.
