=The causes= are limited to the licking of wounds which have been dressed with iodoform. =The symptoms= include gastric disturbance, somnolence, coma, and the signs of iodism. The only =lesions= are those of fatty degeneration of the kidneys and liver. =Treatment= comprises the exhibition of vomitants, stimulants, and diuretics. IODINE POISONING: IODISM. Death by iodine poisoning is absolutely exceptional: the complications described under the name of iodism are rather to be referred to saturation of the organism than to true poisoning. =The cause= of iodism is unduly prolonged administration of iodide of potassium, or of iodine in solution. =The symptoms= include discharge from the eyes, coryza, hypersecretion from all the mucous membranes, and gastric disturbance. The cutaneous eruption exhibits special peculiarities, including desquamation of the epidermis in the form of branlike scales, and pruritus. The first indications in =treatment= are to discontinue the drug and to administer stimulants and nutrients like milk, cod liver oil, etc. STRYCHNINE POISONING. Strychnine poisoning is most commonly due to over-doses of the drug accidentally given during treatment. =The symptoms= comprise tetanic convulsions, hyperæsthesia and dyspnœa. As a result of muscular rigidity, the ribs cannot be moved, and death by asphyxia follows. =Treatment= comprises the use of anæsthetics, and the administration of chloral hydrate, as long as the contractions continue. Bromide of potassium, tobacco, tannin, etc., are also useful. * * * * * The chief part of the botanical descriptions in the following list have been extracted, by permission, from the Annual Report for 1898 of the United States Bureau of Animal Industry, p. 392. To Dr. D. E. Salmon, who gave this permission, and who also kindly supplied the blocks, the writer (Mr. Dollar) desires to express his very sincere thanks. Considerable modifications have been made, and in the case of the more important poisonous plants, details of symptoms and treatment have been added.
