It has been considered that the measurement of carbon dioxide gas released from human skin surface was very important item concerned with various methabolisms of human body, such as skin respiration, blood sugar metabolism and so on. But. the quantitative studies have been scarecely done. In this study, the very simple method for the measurement of the gas released from human skin surface has been established by using the neutralization of the reaction of barium hydroide and oxalic acid. That is ; the wrapper consisted with craft paper and polyethylene film, in which the appointed amount of barium hydroxide (W_O) was packed, were patched on the various parts of human skin surface for the appointed times at same time. It was considered that barium hydroxide reacted to the equivalent amount of carbon dioxide released from human skin surface through the craft paper of the wrapper. Then, the exrta amount of barium hydroxide (W_N) in the wrapper was neutralyzed with the known concentrated oxlic acid aqueus solution. It was suggested that the difference of (W_O-W_N) was corresponded to the amount of carbon dioxide released from the appointed area covered by the wrapper on human skin surface for the appointed times.
