909, 952, 992, and 986 a; the average for all the periods, excluding period 

 1, is 925 o", (2) the pulse cycle after alcohol is shorter, 770, 810, 816, 

 826, and 869 a, the average for periods 2 to 6 being 813 <r as contrasted 

 with 861 a for period 1 ; the smallest average is that for period 2 of 770 o\ 



In section n of table 22, the average difference for all of the normal 

 periods is +21 a, and for the alcohol periods, —49 a. Inspection of the 

 individual differences shows that those for alcohol are quite regularly- 

 minus. On non-alcohol days the signs are more evenly distributed, but 

 the larger number are plus. As seen from section in of table 22, 

 alcohol produces a faster pulse with this subject during the condition of 

 the finger movements by the percentile values of —9.4, —5.6, —9.3, 

 — 12.9, and —7.0 for periods 2 to 6, respectively, the average for these 

 periods being —7.9 per cent. The alcohol effect, i e., faster pulse, is 

 therefore the same as that found in the tetanus pulse and under experi- 

 mental conditions 1 to 7, but is not so large as the average in table 21. 



In considering the probable cause of the relative acceleration of the 

 pulse after alcohol, Dodge and Benedict pointed out that the mean vari-
