TABLE Y —ConliniLed. 

 QUANTITIES OF FLESH FOODS CONSUMED (meat, fish, 



shell-fish, poultry) 

 (In "portions" of 100 calories each). 



Table V shows that during the first period all except E. and Lw. 

 reduced their consumption of flesh foods considerably. It is note- 

 worth}', as Tables XI-XIII will show, that these two were the men 

 whose improvements in endurance were probably among tlie least 

 during this period. 



During the second period Lq., W., P. and B. virtually abandoned 

 flesh foods entirely, the " portions " consumed daily averaging nearer 

 zero than .1. These men improved greatly in endurance also. On 

 the other hand, E., Lw., M. and R. reduced their flesh foods the 

 least, and their ranking in respect to increased endurance was in 

 general relatively low. 



Excretions, Body- Weight, Strength. 



The following table of nitrogen excreted in the urine is interesting 

 in connection with the preceding table. It will be seen that the 

 reduction in nitrogen daily excreted corresponds in general to the 

 reduction in proteid consumed. 



' Each figure is obtained by averaging 2 or 3 consecutive days' specimens.
