“…Table I shows the values obtained and it suggests that the amount of water lost was independent of the surface exposed, furthermore, the chloride concentration was increased by a similar amount in both coelomic cavities. the relative volumes of these two cavities (Smith, 1946), it would be necessary for water to pass into the ampullae from the perivisceral cavity in order to permit such a large quantity to be lost via the ambulacral surface. In order to examine the permeability of the various structures present in the starfish, isolated preparations of the tube feet, tube foot ampulla systems, stomach and gut caeca were made.…”
