The resistivity of metals has been considered in the light of modifications to the Fermi energy, Debye temperature, and band structure brought about by changes of pressure, temperature and impurity concentration. The changes of Fermi energy have been formulated in terms of the diffusion thermopower provided the electron scattering is quasi elastic. A new relation between the temperature coefficients of resistivity at constant pressure and constant volume is established and verified for the alkali metals. The implications of the resistivity corrections to the study of deviations from Matthiessen's rule are also discussed.
