  The reformulation of nonequilibirum thermodynamics, to include the treatment
of thermodynamic fluctuations, is applied to the hydrodynamic fluctuations of a
simple fluid. It is shown that the nonequilibrium thermodynamic scheme leads to
the explicit form of the Fokker-Planck equation which describes the time
behaviour of the probability distribution function of these hydrodynamic
fluctuations as well as the irreversible processes which are connected with
this behaviour.
