the disagreements are not without apparently reasonable explanations. 

 It may naturally be expected that variation will exist in the amounts 

 of the effects found in the two series. From the trend of the investiga- 

 tion it is clear that had the first series been as extensive as the later 

 series, a greater degree of correlation would have been found. 



A repetition series by an independent experimenter has proved, 

 therefore, that this subject was affected by alcohol in substantially the 

 same way as five or six other men previously studied. Furthermore, it 

 has verified, in large part at least, the direction of the former results. 

 These contributions are considered of far more significance than alcohol 

 data equivalent in amount on some new and untried individual. The 

 measurement of the alcohol effect from many standpoints on this one 

 man is believed to have accomplished more in establishing results than 

 would have been possible by following the characteristic statistical 

 method and distributing the equivalent data in observations on a group 

 of subjects. 



APPENDIX I. 



DATA CONCERNING THE USE OF ALCOHOLIC BEVERAGES OUTSIDE OF THE PSYCHO- 

 LOGICAL LABORATORY BY THE SUBJECTS OF DODGE AND BENEDICT. 



In the personal history 1 of the Dodge and Benedict subjects, statements 

 were made concerning the last use of alcohol. These statements refer only to 

 the days immediately preceding the first experiment and not to the period of 

 months during which the experiments were interspersed. They are therefore 

 supplemented by excerpts from the original protocols. These data regarding 

 the extra-laboratory use of alcoholic beverages are of significance in the inter- 

 pretation of the alcohol results of the individual subjects. 



Subject II. — October 8, 1913 (normal), no alcohol in preceding week. No- 

 vember 14, 1913 (normal), no alcohol during preceding week. November 20, 

 1913 (alcohol, dose A), no alcohol since the experiment on November 14 (a 

 normal day). December 5, 1913 (normal), " 3 glasses of cider during previous 

 week." December 19, 1913 (alcohol, dose A), no alcohol during the week and 

 no coffee. January 6, 1914 (normal) and January 13, 1914 (alcohol, dose A), 

 no data given. February 3, 1914 (alcohol, dose B), no alcohol during pre- 

 ceding week. February 17, 1914 (normal), no alcohol during preceding week. 

 March 10, 1914 (alcohol, dose B), no alcohol during preceding week. March 

 17, 1914 (normal), no alcohol since March 10 (when a 45 c.c. dose was taken). 

 These notes confirm the statement in the personal history that Subject II was 

 a "very moderate user." They are of importance when it is remembered that 

 of all the subjects compared for susceptibility to the influence of alcohol, 2 

 Subject II shows the most marked effects of the alcohol, his average percent- 

 age being +5.1. 



Subject III. — October 1, 1913 (normal), no alcohol during previous week. 

 January 5, 1914 (normal), seidel of beer and 2 highballs taken during previous 

 week; "nothing yesterday." January 12, 1914 (alcohol, dose A), no data 

 given. January 19, 1914, Monday (normal), "3 or 4 bottles of beer taken in 

 previous week; last Saturday night, also 1 bottle of Burgundy." January 26,
