    The length, diameter and density of cow's hair and pig's bristle was determined using cow's hide and swine's skin.
    Following analysis of variance, the average value for each of these parameters was calculated and compared. The effect of hair on the mass transfer coefficient of water at the body surface was examined. The following were obtained:
1) The maximum density of bristle on the swine's skin used for the determination was only 0.231 hairs/mm², thus we concluded that swine's bristle has hardly any effect on the transfer coefficient of water at the body surface.
2) The cow's hair affected the mass transfer coefficient of sweat at the body surface, but it was only slightly influenced by hair characteristics (length, diameter and density) and hair direction with respect to the air Stream.
3) The influence coefficient of hair is above 1.0 when the Reynolds number is within 5000, but it was lower when this number was larger. It remained at about 0.6 when the number was above 30000.
