  By constructing the super-particle representation of the free boson gas, we
propose a new statistics in which the particles are non-exclusive. This
statistics can be considered as a generalization of Bose-Einstein's. The
possible condensation of this statistical system is studied. It is found that
the chemical potential below the condensation temperature is linearly
proportional to the temperature rather than a constant. With an proper choice
of the exclusion factors $\gamma_l$, Hadane-Wu's fractional statistics is
retrieved in this representation.
