in the Philippines to eat as much rice and as little meat as 

 possible. Some take meat only to improve the taste of the rice. 

 Mothers often say to the children, "Be sparing with your meat, 

 but always eat much rice." 



As mentioned above, my subjects had been in America for 

 more than one year and were therefore accustomed to American 

 diet. Naturally they longed for Filipino food. During the 

 experiments the food was given to them gratis. Since there 

 was no restriction as to the amount they should eat, it was no 

 wonder that they ate to their hearts' content, and consumed 

 much more meat than do their countrymen at home. That they 

 enjoyed the rations was shown in their desire that the expe- 

 riments be continued longer. 



Observations made among some of the Filipino students in 

 New York City who cooked their food themselves showed that, 

 when they had plenty of money, they ate more meat and less 

 rice than when in pecuniary difficulty. 



Incidentally it will be noted that F.O.S. (Tables 1, 2, and 

 3) had a higher nitrogen intake in the second period than in 

 the first and third. In the first period he was eating alone; 

 in the second also he was alone, but took 5 grams of brewers' 

 yeast daily; and in the third, he had a companion at the table. 

 Did yeast serve as an appetite improver here? (Cowgill, 10; 

 Karr, 12.) 



The nitrogen and the caloric intakes of my subjects were all 

 higher than Aron and Hocson found necessary for establishing 

 nitrogen equilibrium; herein lies the reason for their giving 

 positive nitrogen balance in all cases. 



URINE ANALYSES 



The analyses of the urine (Table 11), compared with those 

 of other' urines as given in Table 12, show nothing of partic- 

 ular interest. 



The average specific gravity is lower and the average daily 

 volume larger than those of the urine of Filipinos living in 

 the Philippines, but not than those of white men living in either 

 the Temperate or the Tropic Zones. The difference in both 

 the volumes and the specific gravities may be partly explained 

 by the difference in temperature; my experiments were made 

 in late fall while those in the Philippines, it should be borne 

 in mind, were performed at tropical temperature. 



The urinary nitrogen figures are also higher than thbse for 

 other tropical people observed in their own localities (see Table
