The experiments of Pfeiffer ( '91) and Vl6s ( '26) gave the surface forces of living cells between 10 and 20 dynes per centimeter, which might conceivably be due to interfacial tension. I n order to distinguish between an interfacial and a membrane tension, it is necessary to measure the tension as

These are the relative proportions of materials used by Krahl et al. ( '41) in measuring cytochrome oxidase content of whole ,4rbacia eggs.
I n a previous paper (Tang, '31) the oxygen tension-oxygen consumption curve for unfertilized arbacia eggs was determined. The data were analyzed in terms of equations relating oxygen consumption to diffusion in a single cell (Gerard, '31). The critical oxygen tension, C,, necessary to just insure m
It is generally recognized that the permeability of cells is markedly affected by temperature ; and numerical temperature coefficients have been determined in a number of cases to measure the magnitude of this effect (for examples see the bibliographies given by Hober, '26, chapter 8; Stiles, '24; J
