of the positive pole for about five minutes, and with from ten to fifteen cells, to the painful spot--the negative pole being held to an indifferent part of the body--is likely to promote absorption. At any rate it will sometimes relieve the pain. In the later stages of paraplegia, as soon as there is diminution of electro-irritability in the paralyzed muscles they should be sponged with the Voltaic current, or Faradized; and where anæsthesia is present, a good painting with the wire brush will often be of service. [SN: Paraplegic Constipation.] Paraplegic constipation may frequently be relieved by Faradization of the abdominal muscles, and the troublesome dribbling of urine, so often present, by external Faradization of the bladder--one pole to the pubes, and two sponges from the second pole--one to the sacrum and the other to the perineum. Incontinence of urine in children may be similarly treated. [SN: Emotional Paralysis.] Cases of hysterical or emotional paralysis may frequently be benefited by the application of the wire brush, which also sometimes acts like a charm in removing anæsthesia, which, although originally of central origin, continues after the removal of its cause. Anæsthesia from section of a nerve is sometimes persistent in this way after repair of the nerve lesion. [SN: Locomotor Ataxy.] The wire brush is also useful in sometimes removing the anæsthesia present in locomotor ataxy, some cases of which may be largely benefited also by the constant current to the spine--one pole to nape of neck, and the other to the lower lumbar vertebræ.[20] [SN: Electricity in Mental Diseases.] Electricity is coming into use in mental diseases. Faradism, and especially cutaneous irritation with the wire brush, would seem to be most suitable for cases accompanied by depression or torpor, the stimulating effects being of service in inspiriting the patient, while the soothing influence of a direct application of the _constant_ Voltaic current to the brain may be employed in cases of over-excitement requiring a sedative.
