Abstract
Measurement results on the absorption coefficient, speed of sound, and Raleigh light-scattering intensity in two stratified solutions containing one and two ``double'' critical points are presented. A model describing the temperature dependence of the sound absorption coefficients and light scattering, considering the superposition of all phase transitions existing in the systems, is proposed.
