method of recording reactions, i.e., to use "1" to denote peck- 

 ing at but missing grain; "2", pecking at and hitting grain; 

 "3", pecking, hitting, picking up and dropping grain; "4", peck- 

 ing at, striking, picking up and swallowing grain, or the com- 

 plete reaction. 



On the occasion of the first test the alcohol chicks with the 

 exception of Nos. 22 and 29, pecked after longer intervals than 

 did the normal chicks. Alcohols Nos. 28 and 21 did not peck 

 at all. Alcohols Nos. 33, 39 and 34 went to sleep a number 

 of times before they pecked at the grain. All of the alcohol 

 chicks were quieter than the normal, made fewer random move- 

 ments and showed little or none of the tendency to explore, 

 so apparent in all of the normal chicks. They did, however, 

 peck with accuracy equal to that of the normal chicks and 

 their records show they improved with equal rapidity. 



Alcohols Nos. 33 and 34 made only 24% and 20% of "4" 



reactions respectively on the third day. On the eleventh day 



No. 34 made 51.1% and No. 33 made 44.4% of "4" reactions. 



One of the normal chicks, No. 10, made a better record than 



any made by alcohol chicks, making 78.9% of "4" reactions on 



the eleventh day; but the records of Nos. 8, 6 and 1 were not 



so good as those made by some of the alcohol chicks. No. 7 



had 35.2%, No. 6, 44.4%' and No. 1, 47%, of "4" reactions on 



the eleventh day. The following table shows the comparative 



rate of progress of normal and alcoholic chicks of the second 



group.
