conductivity is not merely perfect conductivity (hare, h is the enthalpy per
unit mass, and t.'' other symbols have their customary meanings). The curl
equation of the London theory

does not follow simply from the condition of zero vie?oeity of the fluid.
Equation (3) involves a condition more stringent than zero viscosity.. This con-
dition iv exprvesed by-saying that there ran be no "internal motion" of tho

The behavior, at absolute zero, of an electron fluid without viscosity is
examined. Introducing the Lorentz force, thr hydrodynamical equations of motion
using the Eulerian equations are set up. These lead to the nonlinear equation
