If e is small enough, it is plausible that this travelling wave perturbs to a wave of Equation (3) but there are two reasons for caution; firstly, it is a singu lar perturbation as higher derivatives are being added and, secondly, we know that the sixth order term must be relevant.

For a class of potentials, we show a simple functional relation among secular coefficients of the harmonics in the naive perturbation series.
