title: THE CELL SAP OF VALONIA AND HALICYSTIS.
abstract: Comparison is made between the saps of Valonia ventricosa of Florida and the Bermuda Halicystis, formerly known as V. ventricosa. An even higher percentage of potassium is found in V. ventricosa than in V. macrophysa, while Halicystis has been shown to have very little.
