Zero-frequency magnetic fluctuations in homogeneous cosmic plasma
  revisited
  Magnetic fluctuations in a non-magnetized gaseous plasma is revisited and
calculated without approximations, based on the fluctuation-dissipation
theorem. It is argued that the present results are qualitative and quantitative
different form previous one based on the same theorem. In particular, it is
shown that it is not correct that the spectral intensity does not vary
sensitively with $k_{cut}$. Also the simultaneous dependence of this intensity
on the plasma and on the collisional frequencies are discussed.
