CHICKS HATCHED FROM ALCOHOLIZED EGGS 125 



All of the alcohol chicks made two or more wrong choices 

 after the first trial. Several tried to peck their way through 

 the side and two tried repeatedly to fly out at the back though 

 they had several times found the path to the box. There is 

 not one instance of this kind of behavior in the case of the 

 normal chicks of this set. Two of the alcohol chicks went to 

 sleep and had to be prodded repeatedly. 



No. 27, whose record in Maze 1 was as good as that made 

 by the normal chicks, found the right path, chose it three times 

 in succession, made one wrong choice in each of the three fol- 

 lowing trials, went straight to the box in the seventh, eighth 

 and ninth trials, then hesitated a long time before making a 

 choice on the tenth trial. 



Alcohol No. 35 failed to find its way out of the maze. The 

 first trial it was slowly pushed to the entrance at the end of 

 twenty-five minutes. After an interval of thirty seconds, during 

 which it was allowed to feed with the other chicks, it was re- 

 placed in the maze. At the end of twenty -five minutes, during 

 which it had repeatedly gone to sleep, it was replaced with the 

 other chicks. 



The following table gives the results in detail:
