HEREDITY OF WILDNESS AND SAVAGENESS IN MICE 



35 



diately below this, the results for savageness are treated in a like 

 manner. Following this are given, (/) the difference between 

 the number of days required for the tests in Group 1 and in 

 Group 2, (g) the difference in decrease in the average grade of 

 wildness of Group 1 and Group 2 as shown by the difference
