298 LINUS WARD KLINE 



although the subject was inclined to think at times that the 

 stimulus had a quieting, restful effect. Here the middle section 

 from 7 to IIP is quite conspicuous and of normal length. D's 

 M.V. is 3.25 seconds. 



Fs (U) curve is platted on the same graph with A's on account 

 of their similarity in methods and in attitude of work, the vari- 

 able factor being the stimulus, F was four periods longer in 

 mapping the case, and it took him 33 more distributions to 

 learn the order of the cards. The graphs show, however, that 

 he reached the middle section on schedule time, 7P, one period 

 later than A. Fs initial record is considerably shorter than A's 

 due doubtless to the latter's motor sluggishness. A excels F at 

 6P only, due perhaps to A's superior knowledge of the boxes at 

 that time, having finished the map at the preceding period. The 

 only considerable variations in the curve occur in the maximum 

 section at 3 and 5P. There were no subjective disturbances 

 reported from the stimulus effects during the 3P but during 5P 

 both taste and noise proved a disturbance. He reported* a 

 feeling of relief when the noise ceased. The general form of 

 the curve is not unlike I's (N) in the slight break at IIP at the 

 end of the middle section and in the uniformity of the diminish- 

 ing section. Consciousness and habits in his case maintained 

 favorable relations. The growing habit was never seriously 

 embarrassed with excess of knowledge of boxes and order of 

 cards. Fs M.V. is 2.46. 



E's curve (graph 3). (U) shows in exaggerated form a break 

 at 3P, 6 to 9 distributions, that appears at the same place in 

 modified form in nearly all the curves, e.g., A, G, B (slightly), 

 C, F, D, I and J. That is it occurs under normal, pleasant and 

 unpleasant conditions. I first noticed it in a preliminary experi- 

 ment where no stimulus was used. As 3P was the first time the 

 stimulus was given, the fact calls for some notice. The chief 

 cause, whatever it may be, was aggravated by giving the stim- 

 ulus to E and G. Carbon disulphide was used for the first and 

 only time with E and produced a very uncomfortable feeling. 

 G's period came an hour later. The sulphide had been taken 

 from the room in the meantime and asafoetida substituted, but
