A HARD-WORKING DIET. 353 



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 :
