• Abstract 1. A torsion ring method using a suspension wire of low torsion constant was employed for the measurement of a surface viscosity and rigidity of aqueous solutions. 2. The mechanical behaviours of the surfaces of the solutions of saponin, polyvinyl alcohol, crystal violet and horse serum albumin aged for one hour were analysed and expressed using mechanical models. The corresponding rigidity and viscosity were estimated. 3. The mechanical models observed were the Newtonian flow, non-Newtonian flow, Maxwell model with Newtonian or non-Newtonian flow, Voigt model, and three para-meter model consisting of a series combination of a spring and a Voigt element.
