 grams. The rice was served hot; it was, of course, always 

 freshly cooked for each meal as were all the articles of the 

 diet. The meals served were as follows: 



Table I. — Diets employed. 



Breakfast. 



Bread about 100 grams. 



Coffee about 500 cubic centimeters. 



Sugar about 15 grams.

It soon became evident that it was impossible to serve dinner 

 No. V and supper No. IV in an acceptable fonn to the subject of 

 the experiment and, therefore, these were eliminated. The other 

 diets were alternated. 



On the ninety-seventh day of the experiment with Groups I, 

 II, and III and on the eighty-first day with Group IV, 100 grams 

 of potatoes and 30 grams of dried codfish were added to the 

 diet and these articles were served at intervals with 300 grams 

 of rice in rotation with the other meals. The following table 

 gives the percentage of phosphorus pentoxide and of the nitrogen 

 in the articles of diet employed throughout the experiment.
