Abstract : The method of Amati, Jengo and Remiddi for obtaining dispersion sum rules from current algebra is analysed in some detail, for the simple case of amplitudes connecting one particle and two currents. A simple perturbation - theory model provides a warning that the assumptions made in the derivation of the sum rules may not always be valid. When they are valid they may be used to give a derivation of the sum rules that is more direct than the one using current algebra. (Author)
