In treating parts subject to cramp while the spasm is _not_ on, give them, along with other parts of the system, _general tonic treatment_, as directed on page 95. This elevates and equalizes the electro-vital action, and relieves the difficulty. TRISMUS. (_Lockjaw._) For traumatic trismus, use the B D current, of vigorous force. Let the wound be kept open and clear, except that soothing emollients may be applied. Place N. P. at the coccyx, or near it on the spine; and then treat, by firm but momentary touches of the P. P., over the lower maxillary--_pterygoid_--muscles and nerves; indeed, over the _entire_ lower jaw and its articulations. Treat five to ten minutes, if necessary, or until the jaws relax. TETANUS. This is substantially the same thing as _trismus_, except that it extends to other parts, and often to nearly all the muscles of the organism. Under ordinary treatment, it is almost invariably fatal. I am not aware that it has been sufficiently submitted to _our_ electrical system to determine satisfactorily the question of its amenability to it. Yet I see no reason to doubt that, in the most of cases, when taken within reasonable time, it may be cured. Use the B D current, in pretty strong force. Place the N. P., _long cord_, at the feet, and treat with P. P. from the medulla oblongata, or from the upper cervical vertebra, all along down the spine, for several minutes--say, three to five minutes. Then pass with P. P. over the whole trunk and limbs. Continue to treat until relaxation takes place, or all hope of relief departs. CANCERS. Cancers take on a variety of forms, distinguished by different names; but since they all require substantially the same electrical treatment, it is unnecessary here to describe them. Begin with the A B current in pretty full volume. [The _volume_ of the current is increased by increasing the quantity of battery fluid.] Use this for several weeks, and then change to the A D current. Treat daily. The time for each treatment must be determined by the judgment of the practitioner; varying it according to the peculiar character and location of the disease. If the cancer be on the face, or on any part of the head or breast, place P. P. on back of neck; but if it be in the stomach, uterus, or any of the abdominal viscera, place P. P. on spine, a little higher than the affected part. Then treat the disease with N. P., _long cord_, so as to run the current immediately _out_ from the lesion, and yet bring the latter on the _negative_ side[E] of the central point in the circuit; that is, within the negative half of the whole circuit. ASPHYXIA. (_Suspended Animation._) Use B D current, pretty strong force. Place P. P. at back of neck--second or third cervical vertebra, and treat with N. P., over all the chest and along the lower margin of the ribs, so as to excite the pectoral muscles, lungs and diaphragm. RECENT WOUNDS, CONTUSIONS AND BURNS.
