To summarize these 18 pairings: 7 were normal con- 

 trol matings all giving vigorous young. Three were 

 alcoholic males by normal females, all gave young. Two 

 litters consisted of small animals, while the third litter 

 was very weak, two of its members died just after birth. 



Five of the matings were made between untreated 

 animals which came from alcoholic parents, second gener- 

 ation animals. One litter of 3 individuals was born, all 

 were weak and defective, one being eyeless and the 3 

 died within ten days. One other litter consisted of only 

 one individual which was born after an unusually long 

 period of gestation. Three of the matings gave negative 

 results. Thus 3 out of 5 second generation matings failed 

 to take, one gave non-viable young, and only one litter of 

 viable young was produced from the 5 matings, as against 

 7 viable litters from the 7 control matings. 



There were two matings of second generation males by 

 normal females. Both of these gave viable young, though 

 one of the females had an unusually long gestation 

 period. The normal mates seemed to have counteracted 

 the weakened condition of the second generation males.
