We show that a definition of the topological susceptibility χ on the lattice in terms of local fields, with the proper additive and multiplicative renormalizations, is well defined, self-consistent and compatible with results we obtain by the cooling method. Moreover, we can follow the behaviour of the multiplicative renormalization during cooling, and check its dependence on the coupling constant. © 1990.
