a cereal diet. On several occasions 

 hospital convalescents excreted no creatinine in the urine. Ex- 

 aminations were made in the regular manner, care being taken 

 to see that no interfering factor was introduced ; also satisfactory 

 controls were made with solutions of known strengths of creat- 

 inine.

ANALYSES OF URINES OF STUDENTS ON ORDINARY DIET AND ON A 

 DIET OF AN EXCESSIVE AMOUNT OF MEAT 



Further experiments were made with two other diets con- 

 taining meat, in moderate and in excessive amounts. The terms 

 moderate and excessive refer to Chinese ideas upon this subject. 

 The students were all in good health, taking daily exercise at 

 tennis or other games, and were living upon a normal, middle-

 a variety of foodstuffs made up into the usual soups and mixed 

 dishes, in which the vitamines and essential proteins are well 

 provided for by many lightly cooked vegetables and various 

 chopped meats. In these experiments it was hoped that we 

 might realize results comparable in nitrogen value to the Euro- 

 pean standard. However, they more nearly approach the 

 results given by Campbell (3) for Singapore workmen, which he 

 attributes to the heat and the humidity. Our results were
