Physiological Action.— Iodine is an irritant, 

 stains the skin yellow, and if used in concentrated 

 form may blister. It is also a disinfectant, deodo- 

 rizer, and antiseptic, and is eliminated chiefly by the 

 kidneys, the skin, the bronchial mucous membranes, 

 and the salivary glands. If administered for too long 

 a time it produces poisoning, the animal shuns water, 

 appears drowsy, has increased temperature, quick 

 feeble pulse, temporary impotence, and great depres- 

 sion. The best and most efficient antidote is starch, 

 which is to be followed by evacuents. The iodides 

 all are very soluble, very diffusible, and are rapidly 

 excreted. Iodine and ozone are set free at the points 

 of elimination, and thus they cause considerable irri- 

 tation at these parts, especially if large doses have 

 been given. They also occasion a profuse mucous 

 discharge, soreness of throat and eyes, as well as irri- 

 tation to the kidneys. 



Both iodine and iodides induce great waste and 

 rapid elimination of waste products, but if used for 

 too long a time cause anaemia, emaciation, and great 

 depression. They are classed as alteratives, resol- 

 vents, and absorbents. Iodoform, on account of the 

 iodine it contains, is a good antiseptic and somewhat
