Comparison of data obtained by Haussühl & Pähl (1986) with ultrasound spectroscopy at 273 K with our data at 280 K (filled circles) and the data sets at ambient temperature from Jakubowski & Ecolivet (1980) (crosses) and Benoit & Chapelle (1974) (open squares). The straight line is a guide to the eye representing a perfect correspondence between the reference data and the other data sets. |
