A STUDY OF THE INFLUENCE OF RICE DIET AND OF IN- 

 ANITION ON THE PRODUCTION OF MULTIPLE 

 NEURITIS OF FOWLS AND THE BEARING 

 THEREOF ON THE ETIOLOGY 

 OF BERIBERI.' 



By Weston P. Chamberlain, Horace D. Bloombeegh, and 

 Edwin D. Kilbouene/ 



I. Introduction: Eelationship of Eice to Beriberi and Poly- 

 neuritis Gallinarum. 

 II. Chemical Composition of Philippine Eices. 

 HI. Experiments on Fifty-six Fowls. 



Group A. 



Twenty-nine Fowls Subsisting on Polished Rice. 



Classes 1, 2, and 3, on polished rice alone. 



Classes 4, 5, 6, 7, and S, on polished rice combined loiih various 

 salts. 

 Group B. 



Thirteen Fowls Subsisting on Undermilled Rice. 



Classes 9 and 10, on undermilled rice alone. 



Class 11, on undermilled rice combined loith sodium chloride. 

 Group C. 



Four Fowls Subsisting on Unhusked Rice. 



Glass 12, on palay or padi. 

 Group D. 



Ten Fowls Undergoing Starvation. 



Classes 18 and 14, on reduced ration of neuritis-preventing rice- 

 Class 15, on water loithout any food. 



IV. General Consideration of Multiple Neuritis in Starved 



Fowls. 

 Y. Eelation op Loss of Weight to Development of Polyneu- 

 ritis Gallinarum. 

 VI. Bearing of these Experiments on the Etiology of Beriberi. 

 VII. Conclusions Drawn from the Observations.
