  It is shown that the empirical rule that the masses of the stable mesons and
baryons of the gamma-branch are integer multiples of the mass of the pi0 meson
with a maximal deviation of 3.3% holds also for the meson and baryon
resonances, regardless whether the spin of the particles is 0 or 1/2. It is
also shown that the masses of the particles with weak decay are integer
multiples of the mass of the charged mesons times a common factor 0.853.
