VALENCY RULE AND ALLEGED HOFMEISTER SERIES IN THE COLLOIDAL BEHAVIOR OF PROTEINS. I. T~E AcTIoN

I t has generally been held in the colloidal literature that different anions of the same valency have different effects on such colloidal properties of proteins as swelling, viscosity, or osmotic pressure, and that the anions could be arranged in definite series according to their influence on these properties. Such series are known under the name of the Hofmeister series. A number of authors have published such series, but the series of no two authors agree. Pauli ~ gives the following series for the influence of acids on the viscosity of blood albumin,
