Table 3 is an arrangement of the records of animals on the 

 basis of paternal and maternal alcoholism. The first group of 

 animals are those from parents treated directly and having no 

 other alcoholic history. Thus the total 153 differs from the total 

 186 animals with treated parents in the third column of table 2, 

 since in thirty-three cases the former group had not only treated 

 parents, but also treated ancestors. The second group contains 

 all the animals with parents of alcoholic descent, but not di- 

 rectly treated, the total number is 408; these are the same ani- 

 mals that compose the fourth column of table 2. The third or 

 last group contains all of the 594 non-inbred animals of the 

 alcoholic lines. 



The individuals in each of the three groups are separated into 

 three classes. The classes of the first group are those with only 

 father treated, those with only mother treated, and those with 

 both parents treated. In the second group the young are classi- 

 fied as those from only father alcoholic, which means the father 

 was descended from treated ancestors which may have been 

 either treated males or females. In other words, this is not the 

 record of a pure alcoholic male line, but merely the alcoholic 

 effects, if any, that reach the recorded individual through an 

 alcoholic father regardless of the origin of his alcoholism. The 

 second column of this group shows the records of animals from 

 alcoholic mothers. Here again the mother's alcoholism may be 

 due to treatment of any of her ancestors, male or female. It is 

 not a purely female alcoholic line, but a maternal alcoholic line. 

 The third column of the second group shows records of animals 

 from parents both of which were alcoholic. 



In the entire second group the alcoholism of the parents is 

 ancestral, not being due to direct treatment, while in the third 

 group the alcoholism is either direct, ancestral, or both. The 

 third group is, therefore, an arrangement of all the animals from 

 alcoholic lines for a comparison of the influences of maternal and 

 paternal alcoholism. 



In the first column of table 3 it is seen that when the father 

 only is treated the results contrast decidedly with the control.
