It is pointed out that the quantization conditions derived by Lu, Wald, and Young in a paper on an anharmonic oscillator are the same as the well-known JWKB quantization condition, particularized to JWKB approximations of the third and fifth orders, which can be derived in a much simpler and more general way. A number of corrections to the above-mentioned paper by Lu, Wald, and Young are also pointed out.
