Abstract
SOME years ago, du Noüy discovered the very interesting fact that blood serum is able to maintain its normal surface tension. When a surface-active substance like sodium oleate is brought on the surface of a serum solution, the surface tension is lowered for a very short time, but in a few minutes regains its original value (whereas the decrease of surface tension of water is a persistent phenomenon).
