Take A D current, pretty _vigorous_ force in _acute_ cases; _mild_ in
_chronic_ affections. If the eruption be inflamed and acute, use _long
cord_ with N. P.; if sluggish and chronic, use _long cord_ with P. P.
Move the two electrodes parallel to each other, upon the patient, about
two or three inches apart; and pass them over all the affected surface.
Repeat the treatment daily in acute affections, and three times a week
in chronic cases.
