N. 



NATURE OF THE RICE EMPLOYED. 



All the subjects of the experiment received exactly the same 

 diet, except in regard to the kind of rice. As the experiment 

 was originally planned, it was proposed to feed three groups as 

 follows : 



I. White rice + rice polishings. 



II. White rice + alcoholic extract of rice polishings. 

 III. White rice alone. 



However, after a few days it was found impossible to persuade 

 any of the individuals to eat further the rice mixed with the 

 polishings or to prepare the polishings so that they would be 

 eaten. Although they were not informed what they were being 

 served to eat, they detected at once that the polishings were 

 mixed with the rice. They were persuaded to eat some of it 

 for a few days, then they persistently refused to partake of it, 

 even though they began to suffer from marked hunger, insisting 

 that it caused gastric disturbances and soreness in the pharynx. 

 The polishings were, of course, uncooked and were mixed with the 

 rice after it was cooked in order that there might be no oppor- 

 tunity for the criticism that the protective substances in the 

 polishings had been destroyed by heat. As there was no object 

 in continuing the experiment if the members of this group (No. 

 I) did not eat the rice, we placed them upon red (pinmua) rice." 



The white polished rice employed throughout our experiments 

 was especially milled and polished for us by Messrs. Smith, 

 Bell, & Co., Ltd. of Manila at their new mills, and the samples 

 contained 0.37 per cent of phosphorus pentoxide. The rice 



" Throughout this article the term "white rice" will be used to indicate 

 the highly polished rice and the terra "red rice" the unpolished rice.
