The studies were conducted at an apartment house located at Yurigaoka, Kawasaki-City and also at a farmhouse in Hino-Machi, Tokyo-to. The subjects were the same college girls as in the previous study and the housewives in those houses also served as subjects. Their physical status almost approximated to the Japanese standard. The subjects performed various daily activities and respiratory gas was collected in a Douglasbag and analyzed at the place using Roken type gas analyzer. 1. At the 2DK type apartment house R. M.

The serum alkaline phosphatase activities was determind of the blind school children, about 40 boys and girls of 6 to 25 years old, by the methods of p-Nitrophenol and “Phosphatabs”. The values of the two methods were compared each other and the following results were obtained. 1) Highy positive correlations were recognized between the serum alkaline phosphatase activities of the two methods. 2) Values expossed by “about Bodansky units” of the Phosphatabs were a little higher than the Bodansky units calculated from the p-Nitrophenol units using the exchange rate of 1.24 or 1.79.
