10 per cent of each other. They are, beginning at the first session 

 with this subject (October 27) 550, 506, 514, 505, 506, 501, 540, 532 c, 

 with a total average of 519 o- and an average variabiHty of 11 per cent. 

 The results are compared in figure 113, in which curves for both 

 squads and for all three factors of the table, that is, average reaction 

 time, standard deviation, and coefficient of variability, are presented. 

 Squad B shows decidedly more fluctuation from experiment to experi- 

 ment in the average reaction time than is found with Squad A. They 

 would seem to have done poorly in the first and second trials with this 

 measurement as compared with Squad A, particularly so when it is 

 considered that the data of Squad A, in comparison to that of Dodge 

 and Benedict, show that these men were somewhat slow in these 

 reactions. Squad B did poorly in their last normal experiment (January 

 5) and on the three low-diet dates made their best records, i, e., 468, 

 478, and 476. Squad A shows, on the contrary, uniform results up to 

 and including December 19. The two sessions of January 12 and 26 

 are remarkably poor for this group, being almost at the same level as
