POISONS AND POISONING 389 



Mercury poisoning results when animals lick off blue ointment, 

 an agent containing a large percentage of mercuric bichlorid 

 that has been applied to kill lice. Drinking water containing 

 mercuric bichlorid in solution has caused poisoning. In severe 

 cases a bloody diarrhea appears. Milk is a satisfactory antidote. 

 In chronic mercuric poisoning potassium iodid has given good 

 results as an antidote.
