If the disease be general in the system, moving from place to place, or causing transient acute pains here and there, give general tonic treatment, three times a week, for several weeks--perhaps a month or two, provided the case be an old one. This will invigorate the nervous system and equalize the electric action. _Relief_ will be afforded soon; but for the sake of _cure_, the treatment of an old case should be continued as here directed. If the disease be _local_, use the B D current, with as much force as the patient can bear without irritating painfulness. Treat the affected part, or parts, with P. P., placing N. P., _long cord_, upon some approximate healthy part, at a point a little lower down than the part in pain. The spine, when convenient, is commonly the best point for it. In treating the painful part, pass the electrode more or less also over the nerves adjacent to the one principally affected. Treat five to eight minutes daily. SCIATICA. This is neuralgia in an ischiatic nerve, commonly the _great_ ischiatic. Use the B D current, strong as the patient can well bear. Place the foot in warm water with N. P., or place the sponge-roll N. P. at the sole of the foot, (the former is the best,) and treat with P. P. over the painful part, and also, more or less, over adjacent parts. It is also well, in order to prevent too much exhaustion of the limb, to _reverse the poles_ every third or fourth time; but in so doing, use the _long cord_ with N. P. PARALYSIS. Take the B D current, medium force. If the paralysis be in a lower limb, place P. P., _long cord_, upon the lower lumbar vertebræ, so as to reach the hypogastric plexus, and treat with the metallic brush, N. P., five to eight minutes, over all the affected parts. Then close the sitting with _reversed poles_, about one to two minutes, having P. P., _long cord_, at the foot, and manipulating over the parts affected, and especially over the lumbar vertebræ, with N. P. This is to prevent depletion by _running off_ the electro-vital fluid too much, and to force the electric current through the nerves in an upward and inward tonic-giving direction. If the disease be in an arm or hand, treat it in a manner analogous to the above; extending the treatment from back of neck to the affected parts. In case of _hemiplegia_ or _paraplegia_, run the current from the healthy _side_ of the spine, (in hemiplegia,) or from a healthy _part_ of the spine, (in paraplegia,) to and through the paralyzed parts, by placing P. P., _long cord_, on spine, and manipulating with N. P., metallic brush commonly, upon the parts paralyzed. Close the treatment with reversed poles for a moment or two, as in the preceding cases. _Old_ paralysis requires considerable _time_ to cure it. Treat about three times a week, occasionally omitting a week. ERYSIPELAS. Take the A. D. current, medium force, in all forms of the diseases.
