It is found that for the odd number of flux quanta, the quasiparticles called the ``composite fermions'' are fermions but for even number-, the quasiparticles are a mixture of bosons and fermions. Therefore, the theory of ``composite fermions'' is internally inconsistent.11 pages, TeXMesoscale and Nanoscale PhysicsStatistical Mechanicstext
