Authors reported that Kapok was much affected on buoyancy by several kinds of mineral oil, as a conclusion of "On the efficacy of buoyant materials" last year. In this paper we will, furthermore, make clear the character of Kapok being affected on buoyancy by animal or vegetable oil, and etc. That is, we measured the Surface Tension of several kinds of oil and infiltrative velocity of them into Kapok. Then we tried some model tests of Kapok, and we followed tests of Kapok Life-jackets. And, the conclusions to which have come to authors as the result of above experiments are as follows: …a) Kapok is affected not only by mineral oil but also by animal or vegetable oil, e.g., Whale Oil or Rape-seed Oil. b) Kapok tends to be more affected by oil which has low Surface Tension. c) Anti-oil coating by painting on canvas cover is scarecely effective to protect Kapok from oil, etc. And, in point of fact, many people have been rescued by Kapok at the sea casualties. Kapok, however, has abovementioned defects in its character as the buoyant material of life-saving appliances. Accordingly, a counterplan, such as using P.V.C. or Polyethylene cover, must be considered against oil for the progress in saving life at sea.
