and dependable for good cooperation in faithfully accounting 

 for everything done. Their diet consisted chiefly of wheat, rice, 

 and beans, and the food value of the average intake amounted 

 to 3,264 calories per day. 



The four subjects studied were natives of Peking, of about 

 average weight, namely, a little over 50 kilograms.

ANALYSES OF URINES OF STUDENTS ON A NONFLESH DIET 



Six students, taking the ordinary courses of instruction, pro- 

 vided reliable material for further experiments. They were 

 living regularly on a good mixed diet, fairly rich in protein. It 

 was thought to be of interest to compare the results obtained 

 from such subjects when living on a nonflesh diet for a few 

 days with the results from the four laboratory helpers whose 

 regular diet includes no meat except that taken at special holiday 

 times. The total nitrogen, urea, and ammonia values are ap- 

 proximately the same. Values for creatinine as they appear in 

 Tables 2, 3, 4, 5, and 6 show marked differences, indicative of 

 the endogenous metabolism, and to a certain extent a measure 

 of physiological efficiency. One laboratory helper in normal 

 health, but lacking stamina, gave no creatinine in his urine.
