RICE DIET.

Glass IJf. Fed on undermilled rice with yellowish-white pericarp, 26 grams 

 {one-fourth usual allowance) . — Fowl number 19' was given a ration of 26 grams 

 of the same undermilled rice as was used in classes 9, 11, and 13, and this 

 amount, one-fourth that fed in class 9, was continued unchanged throughout the 

 experiment. 



A steady and progressive reduction of weight followed accompanied by in- 

 creasing weakness,

Died-. 



On August 11, the 29th day, he seemed disinclined to move, two days later 

 showed well marked early signs of neuritis, and on the following day died. In 

 this case no attempt to save by mixed feeding was made. 



A loss of 34.7 per cent to the time of sig-ns of neuritis and 39.5 per cent to 

 death occurred. 



The sciatic nerves were extensively degenerated. 



Class 15. Water only. — In a previous publication (16) we reported a case of 

 typical multiple neuritis in a fowl that had been given water, but no food, and 

 stated that the same experiments would be continued with a larger number of 

 birds. In all we experimented with 8 fowls and unmistalcably produced the 

 disease in three. Two others very probably had the disease, but we were unable 

 to save them by mixed feeding so could not obtain a clear clinical picture because 

 the signs of neuritis were obscured by those of general weakness. Hoioever, 

 the nerves of these tico foiols showed degeneration. 



The histories of these 8 fowls follow and are given somewhat in 

 detail. 



Fowl number 17 was purchased May 10, 1910, and kept in a cage on mixed 

 diet, consisting of palay, undermilled rice and kitchen stuff, imtil July 14, when 

 all food was stopped. After July 14, he was allowed only water. 



The first signs of trouble were noted on July 26, the 13th day of his fast. 

 He had difficulty in jumping to his perch. On the 21st day he could not get 

 up to it at all. When not disturbed he would stand with head close to the body 

 and eyes closed, but was not observed sitting on his knees. On the 23d day 

 he stood as above and with his knees very straight. When made to walk he 

 showed a tendency to teeter forward. He was evidently very weak and we were 

 unable to feel certain whether his condition was due to pure weakness or to 

 something else. It was feared he would die within 24 hours if he were not 



' This fowl was reported in a paper read before the Manila Medical Society 

 September 5, 1910, and published in the September Bull. Manila Med. Soc. (1910).
