    CHAPTER IV WATER SUPPLIES Water is one of the necessities of life but its need is often not realized until it is difficult to obtain. It forms more than a half of the human body and is constantly being got rid of in the breath, sweat, urine and feces, so that a man loses three to five pints a day according to the amount of muscular work and sweating that he does; this loss must be replaced o1 damage will result to the body.
