not include the values for the first period. It will be seen that in part in the 

 values given in the column of normal averages are in every instance larger than 

 their comparison values in part n of the table, which is another way of saying 

 that the pulse was most rapid in the first period in normal days. The average 

 values for dose A and dose B, part in, are in the majority of instances larger 

 than the comparable ones in part n, but in general the leaving off of the first 

 period on alcohol days has not increased the final averages, 879 and 886, as 

 much as it did for the average of the normal days. Hence as a measure of the 

 effect of alcohol in terms of the average we have —53 and —28 as compared to 

 the previous —46 and —18. 



With the memory data the result of considering the averages in the way sug- 

 gested is opposed to that just described. As the series of words used in these 

 experiments varied, it seemed to the authors that the method of averaging 

 the differences would be misleading, and that if they were to use the data at 

 all, recourse must be made to the averages for a comparison. Reference to 

 their table 20, page 131, will show that the "saving" in the first period is 

 frequently much larger than in any other period during the day. It is clear 

 that if the average for the normal day includes the "saving" of the first period 

 and that for the alcohol day omits it, the comparison will give the normal day a
