Dampness of filter paper, 10-45% moist, put under the pressure of 45g/cm2 wasmeasured by a galvanometer. By this method, the process was estimated how the moisture on the water-proofed cloth under pressure passed to the filter paper un derneath, with the lapse of time. This measurement can be used for evaluating the function of water-proofing: when the moisture on the filter paper was little, the amount of moisture by an electric current meter and the amount weighed in the balance showed almost the similar results ; whereas, when much moisture passed into the filter paper, the galvanometrical value was much at variance with the measurement by the balance. This measurement showed that all-wool flannel and polyestel-and-wool flannel showed no difference in water-proof ness. Two kinds of rayon-and synthetic flannel, processed with water-proofing chem icals, were inferior to the above three in water-proof ness.
