Página 90 - General Character of the Results. In certain qualitative features, the behavior of all the liquids investigated here, except water, is alike, although there are very large quantitative differences. The viscosity increases with pressure at a rapidly increasing rate, so that if viscosity is plotted against pressure a curve of very rapid upward curvature is obtained. This is unusual;
