CORRIGENDA Velocity Correlation Coefficients as an Expression of Particle-Particle Interactions in (Electrolyte) Solutions By LAWRENCE A. WOOLF" and KENNETH R. HARRIS J.C.S. Faraday I, 1978, 74, 933 In eqn (22) the first term inside the bracket should have as the divisor c3No. In tables 2-7, the asterix should be omitted from each of the&. In table 2 the quantity faC should be fca. This is a consequence of the hj not being symmetric ; they do, however, satisfy the relation hj/ci = J;.i/cj.
