essary to know the normal constituents of the saliva. During 

 the last year several investigators have reported on one or more 

 of the salivary constituents but a complete correlation between 

 the dietary and salivary constituents is lacking. The work pre- 

 sented here is very incomplete and represents only one phase of 

 a complete survey of the mineral metabolism being made on a 

 number of adult human subjects. 



The results thus far, given in a brief form in the following 

 table, have been obtained from weekly analysis of saliva sam- 

 ples from six healthy adults, all of whom have been on a fixed 

 diet for a periods of eight weeks.
