• We consider a system of free bosons (bosonic closed string model) which has the conformal and (abelian) gauge symmetry. In this note we state Noether's Theorem explicitly, emphasizing that there is a possibility of the appearance of a cocycle term in the relation of Poisson brackets of Noether charges already in the classical level, and apply it to the system. The cocycle term appears in the case of the gauge symmetry, but does not in the conformal symmetry one. The reason of the difference is not yet understood.
