Criticism of Mecords of Physical Endurance. 



That the fatigue after the March and June tests was in general 

 much less than after the January test was made evident by three 

 substantial proofs. The first was the feelings of the men themselves 

 as recorded in the foot-notes to Table XI. After the March and J une 

 tests, every man of the eight who showed improvement felt " not 

 tired," or " less tired than in January test," which is the same as 

 saying "not exhausted"; or else he had gone " to limit" as in Jan- 

 uary, which means that the muscle itself refused to continue work. 

 The last was usually true of the "leg-raising," "raising 5-lb. dumb- 

 bell (triceps)" and "raising 25-lb. dumb-bell (biceps)". The o\\]y tests 

 in which there was the possibility of being mistaken as to the degree 

 of fatigue were the "rising on toes" and "holding arms horizontal." 

 In the former fatigue comes so slowly, and in the latter the pain is 

 so intense that they prove to be tests of will power or "grit " quite as
