were once adopted in January, it was necessary in subsequent tests 

 to adhere to them, so far at least as always to begin Avith the same 

 test and follow the same sequence of tests as far as the series was 

 repeated. It is clear that one's ability to succeed in an individual 

 test would dej)end greatly on what and how many tests had immedi- 

 ately preceded ; consequently the only modifications in the January 

 tests which could legitimately be adopted in ]March consisted in omit- 

 ting all tests after the first two or three. These first two or three, 

 being taken under the same conditions as before, reflected correctly 

 any change in endurance so far as those particular tests were con- 

 cerned. 



At the final series of tests in June, no omissions from the January 

 l^rogram were made ; to save time, however, the last two parts of 

 test 6, together with test 7 (which came at the end for all the men), 

 wers repeated only up to the point at which they had been carried in 

 January, although the men were able in June to carry them much 

 further, and in raanj^ cases did so of their own accord. One man, for 

 instance (W.), who in the run in January was glad to stop at 10 

 laps, went on in June to 34, running at the same speed until near 

 the end ; and this was done after having more than doubled his 

 former records in almost all of the other tests. The unlooked-for 

 inci'ease in endurance made the June tests much more time-consuming 

 than the tests in January and March. Had the men in June taken 

 test 7, and the two last parts of test 6 up to the same fatigue limit 

 as in January, some of them would have had to remain in the gym- 

 nasium (supperless) until bed time. One of the men, who in January 

 in the last two parts of test 6 raised the 10-lb. dumb-bells 318 times 

 and the 5-lb. dnuib-bells 1,863 times, Avithout doubt could have raised 

 them in June double and probably treble these numbers, but to have 

 done so would have consumed of itself an hour and a half of extra 

 time. 



In view, therefore, of the only partial repetition of test V and the 

 last two parts of test 6, these records are omitted from Table XI. 

 The first part of test 6 (liftuig the 50-lb. dumb-bell) is also omitted, 

 being given separately below. 



The following table (XI) shows the results of the three sets of tests 

 in January, March and June.' This table will repay careful study. 



^ The order in which the tests were taken was not the same for all of the nine 

 men, owing to the lack of a sufficient number of gymnasium assistants in taking 

 the tests. But care was taken that each man should himself i^reserve the same 

 order in all three series of tests. Thus, for the March series he took the first two
