Sodium and potassium suits. — Prdbably 200 grins, may be taken 
as an average amount of sodium chloride (common salt) in the adult 
human body. It is a most important food, and about 16 grms. are 
daily excreted in the urine, 1 and smaller amounts in the sweat and 
fjeces. If potassium chloride be substituted in the food for the sodium 
salt, disturbances arise from deficiency of the latter. The tissues, how- 
ever, retain common salt very tenaciously, so that during a dietary 
devoid of salt it disappears slowly from the urine. 
During its passage through the body, it facilitates the absorption of 
proteid food, and increases tissue metabolism. The following table 2 gives 
the probable relative amounts of sodium and potassium chlorides in 
parts per thousand : —
