5. This author believes that the work of Bernstein is a considerable improvement in clarity over that of Allis. A sketch of the derivation of the flux equations after Bernstein but specialized to zero magnetic field is given in the author’s complete report: Princeton University Plasma Physics Laboratory Report MATT-180, 1963.
