1. The compression method for calculating the surface force of the sea-urchin egg, developed by Cole (1932), has been critically repeated using unfertilized eggs of Hemicentrotus pulcherrimus. 2. Estimation of contact area involved in Cole's equation introduces technical errors. 3. The tension recalculated by another equation including surface area as a parameter is found to remain constant irrespective of change in surface area. This is in conflict with the classical belief that the cortex of the egg of sea urchin is elastic. 4. Neither osmotic swelling nor osmotic shrinkage of the egg affects the tension.
