into a granulated paste with cracked white rice and water, and 

 the amounts eaten by each fowl recorded. In subsequent experi- 

 ments, the fowls were fed when they refused to eat the rice 

 provided. It was found that they would eat voluntarily some- 

 times as much as 85 grams of rice per day, although many 

 fowls may be maintained upon an average of 35 grams of rice. 

 The chickens were weighed every morning before feeding, and 

 the condition of each noted. Fowls dying were necropsied, and 

 the sciatic nerve removed to study the degenerative changes, in 

 as much as Clark has stated that microscopic evidence of poly- 

 neuritis may be observed even a week after the rice feeding has 

 been started. 



THE EFFECTS OF FEEDING WHITE RICE WITH THE COMPENSATED 



SALT MIXTURE 



Three fowls were fed on the white rice used in the subsequent 

 experiments for controls. These developed polyneuritis on the 

 nineteenth, twenty-second, and twenty-ninth days, respectively. 

 Examination of the sciatic nerves by the Marchi method showed 

 typical and pronounced Wallerian degeneration in each case. 



Three more fowls were fed on white rice plus the stock salt 

 preparation. These developed neuritis on the thirty-seventh, 

 thirty-seventh, and thirtieth days, respectively. Degeneration 

 was typical in certain fibers in one case, typical but not pro- 

 nounced in the second, and very pronounced in the third instance. 



The experiment is summarized in Table II.
