Die Versklavung der Seele der Anderen, two years a body of information has been accumulated which shows that the scanning acoustic microscope (SAM) is a powerful instrument for detection of cracks and elastic discontinuities. This ability is due to the dominant role played by leaky surface waves in the contrast of the SAM. When a Raylei
