In freshwater the caiman gains water at the rate of 3.5ml/kg hr or 1.1 pl/cm2 hr. Of this 70% is the result of uptake through the skin, the rest being due to drinking. This gain in water is excreted by the kidneys as a hypotonic urine. Urine sodium losses are reduced by active sodium uptake from the

Mean water movements across the double chitin membrane of the Limulus gill are 5,000-7,000 pmoles/cm2.h. The carapace is much less permeable to water than the gill; this difference is probably due primarily to the greater thickness of the carapace. Variations in serum sodium concentration due to sal
