• 1. A phenomenon identified as plasmolysis was found to be obtainable in Paramecium, when immersed in NaCl solutions from 0.2M to 0.6M or in Na-acetate solutions from 0.1M to 0.7M. 2. In solutions of the same salts either above or below the said concentration ranges, there may be exosmotic flattening of the cell body induced, but no plasmolysis at all. 3. Hypertonic solutions of KCl, KNO_3, CaCl_2, artificial saline and sucrose were never found to have such a plasmolysing effect. 4. Possible mode of action of the Na ions in causing plasmolysis in Paramecium was discussed.
