Query: An improved formulation of Jaccard's theory of the electric properties
  of ice   In the standard derivation of Jaccard's theory of the electric properties of
ice, no fundamental distinction is made between bound and free charges. This
leads to some didactical problems like the ad hoc introduction of the so-called
'configuration vector' $\bf{\Omega}$. However, when the two types of charges
are distinguished, it becomes clear that $\bf{\Omega}$ is redundant and
proportional to the polarisation density. We also show that Jaccard's
formulation contains a wrong formula for the electric susceptibility and that
the correct $\Phi$ factor can be derived from a straightforward kinetic
approach (which Jaccard failed to do).
