218 GENERAL THERAPEUTICS FOR VETERINARIANS 



for copper poisoning (non-poisonous ferrocyanide of copper) and 

 for caustic iron salts, e.g., iron chloride (formation of ferrocyanide 

 of iron); copper salts, the important antidote for phosphorus 

 poisoning (formation of insoluble phosphorus copper), magnesia 

 oxide and magnesia carbonate, the antidotes for acids (formation 

 of salts of magnesia), arsenic and metallic salts (decomposition); 

 iodine and the iodides, the antidotes for the alkaloids in general 

 (precipitation) and for chronic metallic poisonings (formation of 

 metaUic iodides, which are more soluble and therefore more readily 

 eHminated from the body); potassium bromide, which combines 

 with iodine and iodoform, forming potassium iodide; sulphur and 

 potassium sulphide (hydrogen sulphide), antidotes for mercury, 

 lead, copper, tartar emetic and arsenical poisonings (formation 

 of insoluble metallic sulphides); sulphuric acid and its salts, 

 specific antidotes for lead poisoning (formation of insoluble lead 

 sulphate), carbolic acid poisoning (formation of non-poisonous 

 potassium sulphocarbolate), calcium poisoning (formation of 

 plaster-of-Paris) and barium poisoning (formation of barium sul- 

 phate); the calcium salts (lime water, calcium carbonate, chalk, 

 snail shells, oyster shells, egg shells, marble, sepia stones, sugar 

 lime), antidotes for oxalic acid poisoning (calcium oxalate is 

 insoluble and consequently not poisonous); tannic acid and the 

 plants which contain it (oak bark, cortex salicis, salvia leaves, 

 coffee, tea, acorns, nutgall, ink, cinchona, catechu, rhatany root, 

 tormentilla, walnut tree leaves), important antidotes for poison- 

 ing by alkaloids and glucosides (formation of slightly soluble or 

 insoluble tannates), also for poisoning by the metaUic salts, espe- 

 cially tartar emetic, lead acetate, silver chloride and iron sulphate 

 (formation of metallic tannates); ammonia, chlorine and potas- 

 sium permanganate, local antidotes for snake bites and insect 

 stings; old oil of turpentine and ozone water, antidotes for phos- 

 phorus (oxidation to phosphoric acid), albumin, antidote for the 

 metallic salts (formation of metallic albuminates), caustic acids 

 (formation of serum albumins) and chlorine, bromine and iodine 

 poisoning; gelatin and gum, antidotes for metallic poisonings 

 (sublimate poisoning), alum and tannic acid poisoning (formation of
