A HARD-WORKING DIET. | 23 
In this and the following table the amounts of 
common salt and other minerals, and of water taken_ 
in are not mentioned, for these undergo apparently no 
changes in passing through the body. 
By water formed in the body is meant water which 
results from the oxidation of Hydrogen as distin- 
guished from water taken in as such. 
The above table represents a fair average of daily 
outgoings of an adult in health and of ordinary 
activity. Heavy exertion, whether of work or sport, 
will cause, we know, an increase in these outgoings. 
It will be readily seen, the DAILY OUTGOINGS BEING 
KNOWN FROM EXPERIMENTS, it is easy to state what 
the daily intakes must be to keep up the balance so 
that there may be no over-storage or no undue 
demand on the natural storage. 
For a person whose outgoings are as in the above 
table there must, of course, be as follows :—
