Abstract

The experimental observation of critical phenomena in liquid-vapour, binary liquid, magnetic and other systems is discussed. A wide variety of techniques is considered. Each method is treated in detail, and its advantages and inherent problems discussed. Recent precise work is stressed. The results are presented in a normalized graphical form and integrated with data obtained from older techniques whose reliability is assessed in the light of present knowledge. An introduction to the main physical ideas is provided.
