Conclusions. 133 



cording to table 26, part in, that the maximum effect came in period 

 3, as here the proportion of signs stands 80, 17, and 3 for inferior, supe- 

 rior, and neutral functioning, respectively. In no other period is there 

 so large a percentage for inferior functioning. The average effect for 

 each individual period, expressed in percentages and including all the 

 30 measurements, is: period 2, 11.7 per cent; period 3, 9.5 per cent; 

 period 4, 4.8 per cent; period 5, 7.6 per cent; period 6 (s), 8.3 per cent. 

 All are inferior except 8.3 per cent for period 6, which is superior, as 

 previously noted. The maximum average amount of change is at 

 period 2, but period 3 is not far short. The two indications for maxi- 

 mum effect do not absolutely agree as to period, but in general it evi- 

 dently occurs within 90 to 120 minutes after the dose. As the experi- 

 mental periods in the repetition series were 50 to 60 minutes long and 

 a larger variety of measurements (see p. 23) was given within the 

 period, the data do not lend themselves readily to the problem of 

 temporal incidence of effect. 



There are 16 percentile differences from the first series of observa- 

 tions on Subject VI to compare with the results of the later experiments. 

 Classified under the heads "inferior" and " superior," these stand 

 exactly 50 to 50. In 11 of the 16 cases the differences have signs 

 which the repetition series of observations verify regarding the nature 

 of the alcohol effect on this individual. For example, the supe- 

 rior progress in memorizing after alcohol is verified for this subject 

 under the specified conditions employed. In the former series, how- 

 ever, he did better than here, and was, in fact, the best of the three 

 subjects who showed superior performance. Shorter word-reaction 

 time after alcohol is another of these agreements. This one may more 

 properly be looked upon as an individual peculiarity, as it was found 

 with only one other subject (IX). The other agreements call for no 

 special comment. 



There are 5 cases in which the comparable differences of the two 

 series show conflicts as follows : patellar reflex A, 30-gram, lid reflex L 

 and L', eye-reaction time, and pulse during muscle tension. The more 

 or less detailed discussion of these conflicts given in connection with the 

 presentation of data for the individual measurements may be sum- 

 marized in part as follows: 



(1) The different results for patellar reflex A, 30-gram, are likely 

 referable to the condition that the former data were quite limited, as 

 there was only one normal and one alcohol day (dose A) . The former 

 result of slightly lengthened latency with increased amplitude in the 

 primary reflex is abnormal according to the present basis of judgment, 

 but this subject is unique in demonstrating a relatively small and in 

 certain respects peculiar alcohol effect with the reflexes. It is further- 

 more noteworthy that the reflexes alone show facilitation at the end of 

 the day.
