_Treatment._ For =toxic= cases elimination of the poison is the first consideration. For _lead_ carefully graduated doses of iodide of potassium to carry off the offending agent without increasing its poisonous action must be continued as long as the metal is passed by the urine. It may be followed by a course of strychnia, by electricity, massage and blisters. Gouty subjects may be treated with salicylate of soda, alkalies, or colchicum. The victims of Bright’s disease must be treated for the kidney affection. Where there has been =trouble of the digestive organs=, intestinal antiseptics (salol, sodium salicylate, bismuth-salicylate, beta-naphthol) and small doses of arsenious acid will sometimes benefit. In =anæmic conditions= a course of tonics (cod liver oil, iron, quinine, nux vomica) are indicated, and, to improve the local blood supply, nitro-glycerine. A rich stimulating ration, currying, an open air life, and sunshine (in summer a run at grass) are called for. In man with a suspicion of =traumatic origin=, W. H. Thomson strongly advocates a persevering use of the hot water douche to the parts first affected, the hypodermic use of morphia and atropia, and in case of local anæmia nitro-glycerine every three hours. Where there is a suspicion of inflammation he successfully employs absolute rest, with opium narcotism so as to abolish the pain, for twenty days if necessary. Aconite, antipyrin, acetanilid, phenacetin, exaglin, and gelsemium have their advocates, and may benefit in individual cases. A course of arsenic is often successful, and phosphorus and ergot have each proved of value. ATROPHY OF NERVES.
