the head. If in
the throat, place N. P. somewhere on the dorsal vertebrae, and treat with
P. P.--tongue instrument--in the mouth about five minutes, and then with
end-sponge cup externally upon the affected parts as much longer. Use
the B D current, in good medium strength, twice a day.

CATARRH. (_Chronic._)

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.

DIPHTHERIA.

Use the A D current, strong force. Place the N. P., _long cord_, upon
the lower cervical vertebrae, and then treat, _first_, with the _tongue_
instrument, P. P., in the mouth, as far back on the tongue as can be
borne, three to five minutes. _Next_, manipulate with sponge-cup, P. P.,
or the tin electrode filled with sponge, over all the front parts of the
neck and throat, down to the chest, five to eight minutes.

Treat as often as once in two or three hours.

APHONIA. (_Loss of voice._)

This affection requires treatment variously, as it depends on one or
another procuring cause.

If it be the result of recent "cold," inducing acute catarrhal
irritation in the larynx, treat _first_ as for _common cold_, and
_close_ the sitting as follows: Place N. P., _long cord_, of A D
current, in good medium force, upon back of neck or in the mouth, and
treat three to five minutes, twice a day, with P. P., over the front
parts of the air pipe in the neck; mostly over the _larynx_--Adam's
apple.

If it be from paralysis of the larynx, treat with B D current, rather
strong force; placing P. P., _long cord_, on back of neck or in the
mouth, and work with N. P. over the _larynx_, and somewhat over the air
tube of the neck generally. Treat three to five minutes, daily.

If, as is sometimes the case, the difficulty proceeds from a relaxation
of the diaphragm, with general sagging down of the thoracic and
abdominal viscera, so as to draw upon the trachea, then treat the whole
trunk tonically, using the B D current. Place the N. P. low on back of
neck, and treat with P. P. over the abdomen and thorax, and especially
all around the edge of the diaphragm--along the lower line of the false
ribs. Treat with m
