N2  - The velocities of propagation of elastic waves in caesium thiocyanate have been measured along the three orthorhombic axes and normal to the (110), (011) and (101) planes using a double-transducer technique at 10 MHz. The velocities are found to be consistent with the orthorhombic crystal symmetry, and in favourable agreement with a recently published rigid-ion model calculation. The calculated elastic stiffness constants have values C11 = 18'9±0'7, C22 = 20·6±1·0, C33 = 28·1±1·6, C44 = 1'96±0'05, Css = 7·30±0·2, C66 = 3·04±0·07, C12 = 7'8±4'3, Cl3 = 14·8±4 and e23 = 6·3±4GPa. The calculated values for the adiabatic bulk modulus and the low temperature limiting value of the Debye temperature are 13·2 ± 3·5 GPa and 132 K respectively
