people may be the large amount of moisture which accumulates 
in the air while at the same time the temperature rises. Some 
of the observations made in the experiments above described 
accord with this hypothesis. 
NUTRIENTS AND ENERGY. 
The nutrients and potential energy of the food eaten and of 
that digested in the four experiments are summarized in tables 
io and 12. ‘Table 11 shows the balance of nitrogen and of 
carbon. 
In the first experiment the diet was high in protein. The 
subject, a laboratory janitor, was accustomed to somewhat 
active muscular work and had a very hearty appetite. The 
diet was of his own selection and proved more than sufficient 
for the needs of his organism during the experiment when he 
was comparatively inactive. His organism stored both protein 
and fat. 
In the next experiment, which was made with the same 
person, the diet was, the same in kind but less in quantity. 
The ration proved insufficient to maintain the nitrogen equi- 
librium, although some fat was stored. In this case, however, 
the quantity of protein lost and of fat gained were quite small, 
so that the organism was very nearly in equilibrium, especially 
as regards nitrogen.
