The relation between the frequency dependent dielectric constant and the fluctuations in the dielectric polarisation is re-examined from the standpoint of Felderhof's macroscopic theory of electric and magnetic fluctuations. Contributions of the electronic degrees of freedom to the polarisation are included in the formalism; they are treated as an instantaneous and non-fluctuating response to the electric field. The authors results provide a confirmation and extension of results obtained earlier using cavity and reaction fields. As such they should dispel any remaining doubts concerning this subject, which has been controversial for some time.
