If in the head, first give _face-bath_, as in common colds, except with
_reversed poles_ and changing to the A D current, _very mild_ force. If
in the throat or bronchial tubes, place the P. P. of the A D current,
with _long cord_, on the back of the neck or in the mouth, and treat
with N. P., _soft_ current, upon the affected parts, eight or ten
minutes.
Repeat treatment about three times a week.
