disturbance. If a large quantity of pure iodine 

 or the tincture is given to a dog, the mouth and 

 tongue will be found discoloured (dark brown) ; 

 there is great pain in the throat and stomach ; 

 severe purging and vomiting — the vomited matter 

 may be yellow or brown from the iodine, or blue, 

 if there is any starchy matter in the stomach ; 

 and the breath has that peculiar unmistakably 

 iodine odour. Dogs very seldom, indeed, are 

 poisoned with iodine in this way, though it is 

 not at all an uncommon occurrence for dogs to 

 be slowly poisoned with iodide of potassium, or 

 in some cases by the pure iodine, through absorp- 

 tion into the system by the skin. The latter 

 should never be given, and only the former in 

 small doses, say from half 1 to two grains, and 

 even this quantity should not be continued too 

 long. When it is, or large doses are given, the 

 dog soon loses flesh ; he has an almost unquench- 

 able thirst, the result of gastric catarrh. Vomit- 

 ing is frequent, especially after taking a large 

 quantity of fluid ; diarrhoea may be present ; the 

 tongue is of a dark brick-red colour ; saliva flows 

 freely from the mouth, and there is no desire for 

 food. 



Treatment : In cases of acute poisoning, if the 

 patient does not vomit freely, an emetic should 

 be given, as from five x to twenty grains of sul- 

 phate of zinc in water or some ipecacuanha wine ; 

 give starch and water, also white of egg, and 

 water in large quantities, and allow milk ad 

 libitum.
