Abstract
Talk given at QCD 97, Montpellier, July 1997. In the first part of the talk, I presented a review of the results for the light quark masses obtained on the basis of chiral perturbation theory. As this material is described elsewhere, the following notes only concern the second part, which dealt with the behaviour of the effective theory in the large N_c limit.
