190 KNIGHT DUNLAP 



to rest the hand in spite of instructions to the contrary, hence 

 he was allowed to support it on the paper from the start. The 

 tracings were from left to right, as in normal writing. It has 

 since been found better to turn the sheet upside-down and work 

 from right to left. 



Comparison of the records with the personality and behavior 

 of there actors is instructive. Reactor A is past thirty years 

 of age, not a regular drinker, but has taken drinks socially at 

 long intervals during the past ten years. Has never been intoxi- 

 cated. Brilliant intellectually, physically vigorous and athletic. 

 Blood pressure unusually low. Showed no symptoms of intoxi- 

 cation during the test, except a flushing of the face. No ill 

 effects until eight hours afterwards (evening). Then dizziness, 

 weakness, and nausea with vomiting. Felt better after relieving 

 stomach, and showed no effects when seen the next morning. 



Rector B is past twenty-five; had seldom tasted liquor or other 

 alcoholic beverages. Keen intelligence, but emotionally unstable, 

 in the sense of being easily depressed or elated. Tends to be 

 excitable at times; has plenty of grit and persistence, physically 

 and intellectually; has slight hyperthyroidism, but otherwise 

 physically sound. Stands exercise (walking, tennis, dancing) well. 

 Has been described as ' 'a good sport. ' ' Blood-pressure normal, but 

 pulse rapid. This reactor showed evidence of intoxication at 

 an early phase of the test, and at the end was hysterically drunk; 

 laughed a great deal and staggered violently in attempting to 

 walk. In the test preceding the final one, worked with the chart 

 upside down without noticing it. About an hour after finishing 

 became sick and vomited. Felt better later, and ate some 

 lunch. Sick again in the evening, passed miserable night, and 

 had characteristic sick feeling and headache in the morning. 

 Strong revulsion against alcohol, and usual "never again" at- 

 titude, which lasted five days. 



The individual differences are strong here, and emphasize 

 the danger of conclusions- from experiments on alcohol which 

 neglect the correlation with the physiological and psychological 

 characteristics of the reactors. The necessity of prolonged 

 observations on each subject is also indicated. Subject A very
