Abstract
Calculations from the centrifugal force necessary to pull an Arbacia egg into 2 nearly equal parts, a yolk half and a clear half, indicate that the tension at the surface for 25% increase in area is less than 0.2 dyne per cm., with considerable variation in different eggs. Similar calculations based on the force necessary to pull an oil spherule away from the remainder of the egg give maximum values of 0.33 dyne per cm. for Chaetopterus, 1.1 for Illynaasa, and 0.54 for Cumingia.This publication has 2 references indexed in Scilit:
