PHOSPHORUS STARVATION : I. 



87 



I have analyzed both varieties of the rice, samples of which I obtained 

 from the captain, and also samples of his former "Calcutta" rice. The 

 differences in the phosphorus content are exceedingly striking; slight 

 variations in the nitrogen content are also to be noted. The following 

 is the table of analyses :

Another occasion to study the connection between food and beriberi 

 arose owing to an outbreak of the disease among the lepers at Culion. 

 Here a careful, exact investigation of the data, such as was made in 

 relation to the ship's crew, was impossible, because the people, or at 

 least a part of the people at the leper colony, obtain their own food- 

 stuffs, growing a little rice and catching a few fish, etc., but from the 

 list of foodstuffs which I have given below, it will be seen that in Culion 

 also, rice was the main constituent of the food. Beriberi, to a slight 

 extent, practically was present at all times among the inmates of the 

 colony. In November, 1909, the number of beriberi cases increased 

 rapidly, with a still greater rise in December, 1909, and the first part 

 of January, 1910. The following is the dietary :
