Abstract : An N/D model of weak amplitudes analogous to the ladder approximation of Bronzan, Gerstein, Lee and Low is discussed. It is applied to the case of vector-vector current commutators and spinor-spinor anti-commutators. The model does not of course yield the detailed assumptions of current algebra but is consistent with them. It shows how these assumptions are compatible with the analyticity properties usually assumed for invariant amplitudes. By means of the model it is possible to indicate the problems involved if a boot-strap calculation is to yield the results of current algebra. (Author)
