Specific Volume of Plasma and Serum Proteins in Pregnant and in Parturient Women and Their Newborn Children as Derived from Viscosity Measurements.

1 + 0.5w (1 -s)" where -1 is the relative viscosity, i.e., the ratio of the absolute viscosity of the suspension to that of the pure solvent. The symbol (p stands for the volume fraction occupied by the dispersed substance or solute expressed either in percentage or in cubic centimeters (cc.) per 100 cc. of solution. Hence, sp divided by the weight of the solute per 100 cc. of solution represents the specific volume of the solute. This should be constant for various concentrations of a solute or a suspension unless the solute or suspension is hydrated or solvated to an extent varying with the concentration. On expansion the equation becomes
