  Using phenomenological formulae, we deduce the masses and quantum numbers of
the quarks from two elementary quarks ($\epsilon_{u}$ and $\epsilon_{d}$)
first. Then using the sum laws and a binding energy formula, in terms of the
qqq baryon model and SU(4), we deduce the masses and quantum numbers of the
important baryons from the deduced quarks. At the same time, using the sum laws
and a binding energy formula, in terms of the quark-antiquark bound state meson
model, we deduce the masses and quantum numbers of the mesons from the deduced
quarks. The deduced masses of the baryons and mesons are 98% consistent with
experimental results. The deduced quantum numbers of the baryons and mesons
match with the experimental results exactly. In fact this paper improves upon
the Quark Model, making it more powerful and more reasonable. It predicts some
baryonsalso. PACS: 12.39.-x; 14.65.-q; 14.20.-c keywords: phenomenology,
