FOOD SALTS IN RELATION TO BERIBERI. 135 



tissues, we may never be able to express in terms of chemical equations 

 the pathologic processes of this disease, but I believe we do know 

 enough of its etiology to prevent its occurrence. 



By a proper diet we hope to eradicate it from the native troops. Of 

 course, predisposing causes, such as bad ventilation, overexertion, ex- 

 posure, etc., must receive their share of attention. As a result of our 

 studies, certain changes are to be instituted in the Filipino ration. The 

 rice is to be reduced to 16 ounces and native No. 2 rice substituted 

 for the polished Siam grain now supplied. One and six-tenths ounces 

 of beans are to be added. It is hoped that by these changes beriberi will 

 disappear from the Scouts.
