values. The pulse data are given and averaged separately for each of 

 the experimental conditions 1 to 7. 



The total averages reveal that the pulse level for the initial period is, 

 on the average, practically identical for the two groups of days, being 

 1037 and 1033 cr, as shown at the bottom of the table in the column 

 headed Period 1 . This average may be relied upon, as a comparison 

 of the individual averages in this column shows that the average 

 pulse duration for the first period of June 29, July 1, and July 3 is al- 

 most always approximately the same as the average for the same period 

 on the corresponding alcohol dates, June 30, July 2, and July 4. 



Inspection of the general averages for duration given in the next to 

 the last column of the table 1 will immediately show that in every case 

 the averages for the normal days are larger than the averages for dura- 

 tion in the first period of these days. Thus, for the pulse preceding the 



1 These averages are for periods 2, 3, 4, 5, and 6 and do not include period 1.
