It is found that Chambers' formula for the response of the conduction electrons of a metal to an internal transverse electric field must be supplemented by a diffusion current when it is used for longitudinal fields. A new derivation of Chambers' formula is given by means of the Boltzmann transport equation, and the additional diffusion term in the current is exhibited explicitly.
