  Practical expressions are derived for evaluation of electrical and thermal
conductivities and thermopower of degenerate electrons in the outer envelopes
of neutron stars with magnetic fields. All tensor components of the kinetic
coefficients are calculated (those related to conduction along and across
magnetic field and to the Hall currents). The kinetic coefficients are
presented as energy averages of expressions containing energy dependent
effective relaxation times of two types, associated either with longitudinal or
with transverse currents. The calculation is based on the effective scattering
potential proposed in the previous paper (astro-ph/9903127), which describes
the electron-ion and electron-phonon scattering, taking into account
correlation effects in strongly coupled Coulomb liquid and multi-phonon
scattering in Coulomb crystal, respectively. Analytic fitting formulae are
devised for the effective relaxation times at arbitrary field strength. Basing
on these results, we calculate the transport coefficients at various
temperatures, densities, and magnetic fields pertinent to the neutron star
envelopes.
