Abstract
1) Upon drinking 50cc of the water of Unagiyu Spring, Narugo Spa (pH 9.2), 3 sucklings fed with mother's milk showed always higher pH values in their urine as compared with that before the drinking, but little, if any, change in the pH values of their feces. The 3 cases fed with cow's milk showed no change in the pH values of their urine too. When, however, the larger dosis of 300cc is given per child in 3 portions in one day, the infants fed with cow's milk (4 cases) also excreted considerably alkaline urine in 3-6 hours. The pH values of their feces, however, showed little change in these cases, too.
2) Upon drinking 50cc of the water of Takinoyu (pH 2.2), the pH values of their urine fell slightly in both mother's milk fed and cow's milk fed sucklings, but no change was observed in the pH values of their feces.
3) The pH values of the urine show a tendency to alkalinity in normal infants (16 cases) in 1 and 2 hours respectively after drinking 100cc and 200cc of water of Unagiyu. In normal school boys and girls (12 cases), the pH values of the urine also show alkalinity in 1 to 2 hours after drinking 100cc, 200cc or 300cc of the water of the same spring.
4) The urine of normal infants (11 cases) and primary school children (12 cases) show a tendency to slight acidity in 1 to 2 hours after drinking 100cc and 200cc of the water of Takinoyu.
