POISONING BY BROMINE AND IODINE. 



Poisoning by these agents is rare in domestic animals. Bro- 

 mine 2 drs. killed a dog in 5 hours; 10 to 12 drops in i oz. 

 water intravenously killed a dog suddenly, and 5 to 6 drs. of 

 iodine by the mouth killed in a few days (Orfila). A horse had 

 colic from taking y^ oz. iodine (Tabourin), others died from the 

 effect of 2 drs. doses intravenously (Patu). 



Symptoms. Violent colicy pains, salivation, emesis in vomit- 

 ing animals, diarrhoea, iodine or bromine odor, acute coryza, red 

 eyes, dilated pupils, weakness, debility, vertigo, convulsions. 

 If the patient survives the glandular sy-stem undergoes atrophy, 

 with emaciation and scally skin eruptions. 



Lesions. After large doses there are congestion, ulceration, 

 corrosion and sloughing of the oesophagus, gastric and intestinal 

 mucosa, and more or less yellow discoloration of the parts. The 

 odor is characteristic. With iodine there may be blue iodide of 

 starch in the ingesta. 



Treatment. Favor emesis b}' tickling the fauces and giving 

 tepid water, orapomorphia subcutem. Boiled starch is the best 

 antidote and may be given freely, both by mouth and rectum. 

 Opium is often called for to relieve suffering.
