Problem I. — Relationship between the Number of Ovules formed 

 per Pod and the Percentage of Parasitized Seeds. 



In Tables I-II are shown the number of ovules formed per pod, 

 the total number of seeds matured and the number infested by 

 weevils. 



The most logical method of comparing the numbers of infested 

 seeds in pods with various numbers of ovules is to reduce actual fre- 

 quencies to percentages for each class of pods, i. c, 



Infested seeds X lOO 



Total seeds 



as given in the fourth column. 



TABLE I. 

 Infested Seeds in Golden Wax Beans. 



TABLE IL 

 Infested Seeds in Burpee's Stringless Beans. 



In both series the frequency of injury by weevils increases as the 

 number of ovules per pod becomes larger. There is only one ap-
