• Further features of the plasmolytic phenomenon as was observable in Paramecium cells placed in a hypertonic solution of Na salts were studied. The phenomenon proved to be reversible, though in a small percentage of plasmolysed cells, when the cells were brought back to the normal, hypotonic medium. It was shown that K^+ as well as Li^+ had an effect similar to that of Na^+ in enabling the plasmolysis to take place. Ca^<++> ion, on the other hand, was found to antagonize the said action of Na^+ ion at Na^+/Ca^<++> values below 135, the plasmolysis being inhibited completely by the presence of Ca^<++> in a molar concentration higher than 1/100 of that of Na^+. The possible modes of action of external cations in facilitating and preventing the plasmolytic event were discussed.
