FURTHER ANALYSIS OF THE PROTECTIVE VALUE OF BIOLOGICALLY CONDITIONED FRESH WATER FOR THE MARINE TURBELLARIAN, PROCERODES WHEATLANDI. IV. THE EFFECT OF CALCIUM

R. B. OESTING 1 and W. C. ALLEE 1

1 From the Marine Biological Laboratory and the University of Chicago

1. An increase in the calcium content of extremely hypotonic water, when the calcium content is less than that found in sea water, delays the onset of fatal cytolysis for Procerodes wheatlandi isolated in such media.

2. Other electrolytes, even when increased appreciably, do not show this same protection; however, some protection of an osmotic nature is apparent.

3. The increase of calcium in biologically conditioned fresh waters is adequate to explain their observed protection for Procerodes.
